Can you put eco mode to be 125W manually somehow and test it ? I saw somewhere on forum that some guy put manually at 125W, he got almost same perfomance as stck (-+1-2%) but temps are between 70-75c undel load with nzxt x73
@@strehicabih5246 You can find the PBO values for any TDP with a simple interpolation on the values provided by AMD for 65, 105 and 170W. Following this, I set my 7950X to 125W TDP with the PBO settings : PPT=169W, TDC=125A, EDC=187A , this gives acceptable thermals (80°C max with high end air cooling) and performances even closer to the stock ones. Adding a slight undervolt using the Curve Optimizer setting, performances are even better than stock, with a 30% energy saving! If targeting 125W TDP, 105 being 20 less than 125 and 65 less than 170: PPT = 142 + (230-142) * 20/65 = ~169W TDC = 110 + (160-110) * 20/65 = ~125A EDC = 170 + (225-170) * 20/65 = ~187A
He should go to that cat sanctuary on Lanai that Dr. Ian Cutress went to (on his TechTechPotato channel a while back - "How to Pet 600 Cats"). Besides it being a cool haven for cats, it's on a Hawaiian island, so a great place to visit and unwind - and maybe visit the other islands as well.
Agree with those conclusions 105W definitely seems the way to go, but can we appreciate that chip in 65W mode managed to run all 16 cores at 4GHz and did it at only 19 degrees above ambient. That seems mad. The mobile versions of these chips are surely going to be monsters.
These cpus should have launched with 105w tdp and 170w should have been optional. That would have given much better press and 95*c issue wouldnt have existed
Dragon range is supposedly going to be an around 60W TDP mobile chip with more than 8 cores. I wonder if they'll do something like a 7950HX that's basically the soldered version of this.
@@DigitalJedi dragon range is literally Ryzen 7000 desktop on mobile. The reason they can do this is because the IO die on Ryzen 7000 was built from the IO section of Ryzen 6000.
Think of it like this - people used to overclock back in the days to get massive gains in performance but now, company's have pushed the cpu to limit, there is nothing left to over clock BUT you can undervolt your CPU massively to gain efficiency instead of power. This way, people who care about efficiency win, and people who care about mad performance also win
With all vendors pushing their products hard out of the box it seems opting in for efficiency is something that’s going to be more commonplace. These efficiency results bode well for Zen 4 mobile!
If you have 2 CPUs for the same price. One is less performance but more efficient, and one is less efficient but has more performance. The one with the most performance is going to outsell the one that's most efficient every time. "Efficiency" is almost exclusively an argument that a fanboy uses to defend their favorite brand when it falls short on performance. X is more efficient than Y, so X is a better per watt value. Meanwhile the rest of us are popping the IHS's off our CPUs and using liquid metal to run more power through them.
@@twiggsherman3641 For some users that's certainly the case, but not everyone. I'll happily take a 6% (at worst!) performance hit if it reduces total power consumption - which directly relates to both heat output, and electricity bill - by 40%. That's a nutty trade-off. I fully respect enthusiasts wanting to push peak performance, even if they have to double their power (and heat) to reach it. Great for them! I'm enthusiastic about efficiency. I still want great performance, I just don't want a space heater in my room to get there.
@@twiggsherman3641 Well, ideally you want one that can do both! That way if you care not for the power use you can get max perf but if you care for power or heat production, you can still get good performance :)
@@twiggsherman3641 You mean like when Intel did the same back in the day:)? Sorry, but power efficient is still a thing. Even if you have the highest performing SOC... if it runs at a blazing hot to cool - it wont matter because people will still see it has something that can't really afford if they're paying 100s of extra dollars just to run and cool it. There is also still the mobile half that does have to play the efficient game because of the battery limits we still have today.
@@John__K well,, we do need a psychological shift on that cause before 100C was the most chips could handle long term but Zen 4 design can handle up to like 115C so 95C on these chips is more like 80C on older chips and for all-core thats not bad at all.
@@ImInYourBrains That's nice to hear. However, 70~80C has been the long term safe~zone for cpus since like... forever. Lab tests that try to simulate endurance of decades(hopefully decades and not just 3-5 years) are not enough for me. I need actual time passing of 5+ years under such conditions to get convinced that this doesn't affect their longevity.
Keep in mind that you don't get the same efficiency improvement shown near the beginning of the video for all workloads, i.e. for gaming there's probably no efficiency difference; they should've shown the average power consumption for each test alongside the performance numbers
I understand that GN is usually looking at hardware from a more traditional sense, hence constantly reminding that "300MHz all core". But the reason why many people look at these ECO modes is that the thermals and system noise concerns overcome the significance of the performance. For me, it's not that you "lose 300MHz all core and that's a lot", but rather you "lose 6% of the core clock while reducing 50% power consumption". That's a truly impressive and disproportionate improvement. Personally, I care about these things because I am an ITX gamer nowadays, and there is a limited thermal budget for the system and a limited noise budget for my own sanity. My logic in looking at this is "what's the best performer at certain wattage that my cooling system can handle", and from that point, even a 20-30% weaker than stock 7950X is still within consideration. Although realistically, the best performance-to-cost ratio probably lies somewhere around a TDP limited 7700X or a 13700K for gaming.
From a gaming standpoint, what's your reasoning for the 13700k over the 13600k? IMO the performance gain is negligible to the price difference, and the 13600k outperforms everything in the field in a gaming sense except the other 13 series, and they don't lead by an incredible amount either. I almost don't even understand why the 7's exist anymore, with the 13600k being 14 core 20 thread, and having impressive workbench capability anyways. Seems like if you really needed something more from a workbench standpoint, you would just get a 13900k or 7950x as nothing else really justifies the price to performance difference.
@@guy_autordie I think that's a great option as well. If you are doing it for the noise and thermals that's great. With the price difference over a 13600k if it was done from a more energy saving standpoint you'd have to leave it on nearly 24/7 for a year or use it for a couple to negate the $100 difference.
@@Wrenchingandnursing I just took 13700k as an example of something "not the flagship". I'm not that familiar with the 13th gen lineup, and the i5 may as well be more sensible than the i7 for gaming purposes with a limited power budget. I just vaguely remember that people were picking the 12700k as the sweet spot amongst the 12th gen lineup. I think the mid-range SKUs still have unique spots in this performance vs package power chart. Say we set a 65W power envelope, for the 7600X to the 7950X the average W/core decreases respectively. I think the peak performance per W probably lies somewhere around 6-9W/core like the 105W 7950X, so for a 65W limit the 7700X might make the most practical sense, in that you don't lose 30% of performance like you do for a 65W 7950X, but still has the thermals under control. But that's a very rough guess and might as well be wrong since CPUs work in very complicated ways, and we've seen that the games don't scale very well with these Ryzen core counts, so maybe a 45W envelope 7600X is all you need for the best overall price-gaming performance-noise experience for going AMD. Again I don't know too much about the Intel chips, but they seem to draw not that much power in gaming compared to some other workloads. My guess is that given a certain power limit, the 13700K might still be better than the 13600K, but maybe not by a huge amount, so the 13600K might as well be the most reasonable choice.
I was going to build a sane system to replace my positively ancient 1700X. Now you make me consider an ITX system with a 7950X (or X3D as my timing permits) that's been power limited.
I think dropping 30C is something most people would want and notice far more than the 5% slower CPU. With how fast the CPU is, I think it make sense for most users like that.
if you'd just adjust the PBO curve offset or PPT limits manually rather than using the Eco preset, I'm sure you can get results within 1-2% of the top results while still reducing power and thermals massively. also, remember that it's not always just about the cost of energy. being able to half the output of your 700 Watt "room heater" is a blessing during hot summers.
Probably, similar thing for older 3000 and 5000 series, where manually adjusting the limits can get you pretty close to stock performance while also getting most of the savings of eco-mode. Also don't forget about noise, not everyone has the nicest cooler and although they're much better these days the stock coolers are a bit noisy when they ramp up more than about 30-40%, so being able to maintain that more often is also a big benefit.
Negative PBO curve offset seems stable for days then randomly gives me WHEA errors, it's not something a person buying for a workstation would want to use. One flipped bit might be hours or days of lost work.
@@finestPlugins really? Zen 4 should be better than Raptor-L it’s on the 5nm node, whereas intels 10 super fin thing is probably closer to 6nm (7 with increased transistor density) nowadays
@@tranquil14738 The intel node is less efficient, its just certain benchmarks do better on Intel and therefore "trade blows" even though overall the AMD architecture is infact more efficient, especially with less aggressive boosting. But to be completely honest it's not a huge difference, Intel have optimized their process pretty well and at reduced power frequencies is pretty efficient too. However out the box with uncapped Turbo Boost, Intel consumes ridiculous amounts of power lol
Efficiency is something I believe is a mark of great generational improvement. All the companies can just blast powers each gen to get more performance but getting more performance or getting the same performance as last gen but consuming less power is something truly amazing these days.
AMD should intoduce a 7950E processor. It could be exactly the same but with default 105w tdp. If they saved the better quality binned dies for this the performance would be about the same as well.
@@GamersNexus I am not sure. I mean, would it be better than buying a regular 7950 and set the power limit to 105W? What I do think however the Eco mode should be more promoted and super easy to access, even for user who usually don't change stuff in the BIOS (because people who temper with the BIOS are a tiny minority). At least here in Europe power efficiency matters ... thanks to skyrocketing electricity bills.
105W looks like a great balance of speed and efficiency while 65W would be good for really big tasks where you can leave the computer on for an extended period of time (say overnight or out for a meal or whatever).
17:17 is impressive how the 7950X in 65W ECO mode performs better than the 5950X stock 8' vs 9.4' (16:16) and given the efficiency chart 11.8W vs 18.9W (15:15) if you want the maximum performance with the minimum power draw is an option, in fact with that efficiency I wouldn’t be surprise if we see 16 core CPUs in laptops soon
like wise bro and to think intel might have cheaper platform people only think in short term cost, for me the cheapest electricity bill for years of productivity/gaming wins. That's why i prefer efficiency/performance
This is just what I was looking for. I'd be interested in seeing an undervolting video, as well. A comparison with the 13900K in an "Eco" mode and undervolted would also be interesting. I'm a big proponent of performance per watt.
I'd love to see a 13900K undervolted and maybe even downclocked a bit. I think you could shave maybe 400mhz off of the P-cores and still have a total monster of a chip. The E-cores can mostly be left alone, but taking them down to just 4.0ghz wouldn't hurt to bad either.
105w Eco mode + mild undervolt would further increase the efficiency, including scenarios where only single or few cores get stressed. With no loss in performance, except when all or most cores are stressed
Perfect timing! I was waiting for someone to do a deep dive on ECO mode...great video! I will be building a 7950X in the next month or so...and will run it in ECO mode. Makes a lot of sense not to drive the CPU so hard for such small gains.
Exactly my thoughts. I basically wanted better then ryzen 5000 performance but at least same efficiency. The 105 watt eco mode is even better then expected. It looses barely performance, few % tops, but it still 'crushes' the 5950x, win win situation.
Yeah it's what we were all expecting to find, ya? The 7950X is waaay outside it's efficiency curve at stock settings. I imagine if you could hard limit the PPT to 170w, that'd be where the efficiency curve peaks and you get the best performance for the wattage. Good testing guys! Love this! :D
It's funny how NVidia and Intel did EXACTLY the same. This is just for the WOW effect and also to please investors. The customers and the environment are dirt to them.
If you have a 7950X, you could try to enter the following manually into PBO: 186W, 125A, 197A -> This is exactly in-between AM5 105W cTDP and AM5 170W cTDP mode according to the table at 5:55. I bet you only see slightly lower performance in benchmarks only but won't be noticing ANY difference between Stock and this setting. Also, it will probably still lower temperatures down by 20 Kelvin, which might even result in higher clocks (and thus even higher performance) depending how constrained your cooling solution is!
If you want 125W TDP, which is 20 higher than 105, the diff between 105 and 170 being 65: PPT = 142 + (230-142) * 20/65 = ~169W TDC = 110 + (160-110) * 20/65 = ~125A EDC = 170 + (225-170) * 20/65 = ~187A
@@plaiseek1503 I didn't target a specific TDP here, just something in-between the two. Just for testing purposes. I don't have a 7950X and I won't upgrade until there's a CPU with 3x the single core performance than my TR 3960X and 50% faster than it in multi core.
Totally anecdotal, but I'm running my 5800X in Eco Mode and the heat reduction has been well worth it, especially this past summer. I haven't noticed too much performance reduction in games either, but nothing I run is SUPER demanding. Definitely worth exploring
I'm using cheaper 5700x, it is just a 5800x with Eco mode factory default. I can manually increase its PPT to match 5800x stock. For new buyer with some knowledge, buying 5800x instead of 5700x doesn't make sense.
@@linearz I actually got the 5800x for cheaper than a 5700x on some crazy sale less than half price so in that case I wouldn't say no. I do agree with a big price gap it's not exactly a compelling buy haha but peformance is generally like 2 to 3 percent worse max 5% so very close cpu... The 5800x does sometimes have more substantial single core peformance too but all these things are small anyone would give up to save a chunk of money even if you can eco mode the 5800x and stock it for a lil more juice.
Thanks for all the hard work Steve & GN team. As a graphic designer with a 6 year old entry-level CPU, this has felt like the year to start fresh with AM5, and I'd been waiting on eco-mode reviews to pick between the 7950 or 7900 and find a sweet spot that works for me so this gives me a clear answer.
Just upgraded to 7700X yesterday and met with absolutely fans blasting with first benchmark because of 90+ temps. But I knew that before buying. After enabling ECO mode, which for 7700X would be 65W as it is 105W TDP stock. Huge difference in temps(Barely hear fans as temps stay around 60) and decent power consumption. And while it is not same CPU, I dont expect huge drop in performance with 7700X either.....eco mode is the way to go. I somewhat understand the need to extract everything out of the CPU while sacrificing power and thermals...because performance sells. At the same time, they almost lost my sale if it wasn't for the eco mode, I just wish they mentioned it more. Although it was kinda simple option in the bios if you search it and I believe Ryzen master has it also. I didn't actually know that. After reading couple articles I though you had to input numbers in the BIOS/PBO and thats what I first did. Didn't actually work for some reason, but then I found simple eco mode setting in bios and that worked well.
Try PBO undervolt 20mV.. it's will go from 150w max to 99w max (more or less) with 1-2% loss in frequency it's will be good mix of performnce per watts Am waiting my 7700x to arrive.. still didn't decide what Mobo I should get.. Am leaning between Asus TUF B650 & MSI Tomahawk B650.. Tomahwak is better but slightly more pricy
@@Jack_Sparrow131 I keep that in mind, but dont want to mess too much right now. It works and I'm happy with performance, temps and power. I went with Tuf B650 as I also had Tuf B550 and had no problems with it.

@@Jack_Sparrow131 I bought Corsair 6000Mhz EXPO ram and after updating bios to latest I did enable it. Asus has EXPO I and EXPO II, one being EXPO with some extra ASUS settings I guess.

On first day, I did notice some weird things, like my mouse didn't wake PC up, keyboard did....aswell my PC didn't pick up my TV HDMI when waking up, had to switch to monitor with Win + P and back TV. But day 2 and now 3....mouse wakes it up, TV gets picked up. Looking good so far!
@@Kr1sVr thanks for the details.. yeah seems the bios updates helped a bit for ironing some bugs & compatibility overall I'll guess I'll go with B650 TUF also, it's not great like Strix or even Tomahawk.. but at least it's cheaper & good overall Best of luck to you mate
So basically the 105W ECO mode runs at about 60% of the power and achieves almost the same performance as stock. Almost the same productivity performance as 13900K but consumes half the power.
My personal interest in this is that I donate my spare CPU cycles through boinc when I don't need them. For that, I limit my (4800H laptop) CPU to 20W using power saving mode. In that case, the efficiency is absolutely worth it!! Balanced mode is 10% higher frequency for 75% more power and I don't even bother with High Performance mode. I just suspend boinc when I want to use my computer quickly!
FR this is third time AMD launched 7000 series, there will be confusion for times to come... Why did they do that, idk. Itsenot like they ran out of numbers.
I use "handmade" eco mode on my 5950x. I could immediately feel and see the difference in room temperature (12m² room ) at the end of my workday as I am running VMs, containers and compilers the whole day long
Keep in mind the 65 watt mode is probably for mini atx systems where you can pair it with a small rtx a4000 or a4500 or similiar card so it would also make for a tiny workstation that could be tucked away in the corner of your mancave. You could use a itty bitty air cooler or 120 mil radiator and take up a fraction of the space a tower would and still run cool and quiet by adjusting the fan and power consumption of the small workstation cards.. I'd love to see some tiny workstation builds with this cpu
HP or Dell usually try in their workstation lineups, but forget to configure the TDP limit accordingly and make the whole thing fry itself in two years. I can only hope it'll get better, eventually...
The answer is “fast enough”. Realistically unless you have a ridiculous multi 4K monitor setup, just about any mid range CPU is fast enough for gaming, even at high refresh rates. Once past about 120fps, you are beyond the limits of human biology anyway, any difference is barely perceptible. These high core count CPUs only make sense for compute workloads. For gaming you are just paying extra for bragging rights. If you are a gamer and already have a decent AM4 setup, the 5800X3D will do you fine for several years to come.
@@chrisward000 4K is less noticible than 1080p, where you are CPU bound to hit the upper fps limits at 200fps+. Once you're running 1440p or higher the eco mode is plenty and 1% lows are more important so you don't see fps drops from your fps g-sync cap.
@@tilapiadave3234 A bit overpriced at launch, but recent discounts made it a good option for anyone on AM4 with Ryzen 3000 or older. I would not put one in a new build, but way cheaper than a full system upgrade to go to Ryzen 7000 or Intel.
@@chrisward000 the 3d is basically the same as the 5800x and 5700x at 4k so not a good example even at 1440p its rarely of note. You mostly want it at 1080p as it's a monster for that for those on am4 socket.
I do a lot of Blender type workloads. Stock my 7950x was just way too hot == noisy. Set it to 105 eco and lost maybe 5-7 percent performance maximum. But my machine is relatively quiet now and energy costs have gone through the roof so that's better too
What are your idle, medium low (games) and all core load temps? I'm insanely curious what temp it will be (95°C is unacceptable to me - biggest reason my 3570k Intel lasted 8 years, i do not trust a perma 95°C cpu to make that) but if the eco mode shaves op permanent 10°C in cinebench, all-core loads (and much more in others), that would make me accept it. If it shaves off 20°C while using something like Noctua cooler, I would finally stop doubting the ryzen 7000 series (except for DDR5 and motherboard prices).
@@kw7865 Thanks a lot, that seems totally what i would fine acceptable (much better then 95°C). Friend is recommending me strongly the Noctua ND-12U, over Noctua ND15 but both are on my shortlist.
A small amount of under-volting is what you want. You can get the thermals and power draw down significantly, and the "overall" performance up (due to absent thermal throttling). It needs a PBO2 'tune'. Ideal power is close to stock, but just a bit down.
This actually helps a ton in deciding whether to even bother with Ryzen 7000. 105W Eco being both faster AND more efficient than my current 5950X is very tempting. I'm still waiting for the 3D version, though
First thing I did when I got my 7700X was PBO undervolt by 25mV and reduce the power limit to 85W and the performance was basically the same as stock, but with much lower temps. I was pretty happy with that.
I just ordered 7700x & would try & see.. the reviews says it's around 150w max at 100% usage.. With your 85w, it's like 40% power less power for nearly the stock GHz speed? not bad For me, I'll try to go to 105w (undervolt) with slight OC (might be able to get a better boost?) BTW what Mobo did U get? all the B650 I found was expensive.. Asus B650 TUF is $240 while MSI Tomahawk is $270 I like Tomahawk because it's have better thermals & more sata 3 ports.. but the TUF price is better Feels hard how my B450 Tomahawk was $100 in 2019, while this new Tomahawk is $270 (2.7x increase)
Have they ever thought to factor in the effect of Steve's hair falling into the PC cases and how it could affect airflow and temps? I mean, dude has a lot of hair! 🤣
I'd actually love to see GamersNexus do a dedicated deep-dive video on PBO curve optimizer for the new Ryzen generation. Since a lot of Ryzen users tend to optimize their boost clocks via an UNDERvolted (negative offset) PBO curve optimizer, I'd love to see GN revisit the topic of Ryzen's curve optizer and achieving good clock numbers that way while reducing power.
I actually had a 5950X running in Eco mode but mostly because it was installed in a small form factor system. Only took a hit in multi core performance surprisingly.
That makes sense. Boosting only 1 of 16 cores should stay well within the power limit when the other cores aren't loaded heavily, and of the other cores are clocked lower to begin with because of the ECO mode, you can actually send more power to that single core due to the additional thermal headroom. I noticed something similar when I was undervolting my 9750HK laptop. I lost about 10% on multi-core performance, but gained 9% on single-core while never touching the 135W power limit. I actually stayed below 120W even in a full Cinebench R23 10-minute test.
@@glosan9516 Do you use the default Eco mode or do you have a handmade one? I am running (95W TDP): 128W PPT, 80A TDC, 125A EDC but hoping to see if anyone finds a better balance based on the efficiency curve like what Debauer showed for NVIDIA.
Surprising results, but at the same time not too surprising results. This is just how CMOS works: Power consumption scales exponentially compared to switching frequency. The 105W results, however are very surprising. Thanks.
So, TL;DW, 105 eco mode is for productivity, 65 eco mode for gaming, and stock if you want to compensate for something, have a seriously intensive CPU workload, really love the sound of fans at 100%, or you're too cold. Great breakdown, as always, from Tech Jesus.
The 65w mode is perfect for making a professional workstation the size of a shoebox. Most artists are freelancers, and the desire for smaller and lighter weight workstations is real.
105w mode can be used for cost saving. You can get a cheaper cooler, or more likely not replacing an existing cooler. It may also allow you the extra headroom on an existing power supply to allow for a GPU upgrade, without requiring a PSU replacement.
I have been undervolting/limiting basically everything lately. Those last 5% for the price of 30% are not my thing in the current market and noise preferences.
This is my first time watching on my monitor at 4k and wow the new cameras are paying off, Amazing DoF, RT, Steve with Global illumination is just tooo real.
As an audio professional, 30 degree drop while staying with 90-95% of stock performance is HUGE. Less heat means less fan noise, which is a big deal when the thing that makes you money is your ability to listen. What an awesome CPU
Ecomode could be well worth it in select circumstances, as power cost approach the cost of the cpu itself. With 170W saved in 65W ECO, with 24/7 operation and power costs at 0,4€ (not unseen in Europe right now) the CPU would gulp 595€ in just a year. At the end a 100% utilization is unlikely though and opportunity costs can be significant. 105W ECO could be a good tradeoff for highly efficient computing and lower running costs.
With a 25% perf drop you lose 1000€ (Cpu+Mb)* 0,25 = 250€ in opportunity costs (roughly), so you need to redline your cpu but you could save maybe/roundabout 300€/year.
I power limit my 4090 to only 80% and don't feel bad at all. It performs light years above my 3090 Ti still. I undervolt my 5900X as well and it does better in performance and temperatures.
I UV 5800X somewhat out of necessity, running Hyper 212 Evo cooler, and prefer under 80C for video transcodes. I am able to get essentially stock performance though. They say 95C is fine, but I would rather have more safety margin.
I kept looking at 0.1% and 1%. It looks like stock is doing quite a lot better there and 7700x was doing by far the best in a lot of those - the “top” CPUs in some of those were dropping under 60fps for 0.1%.
I actually really think eco mode has a place in the laptop market. Imagine being able to plug in your laptop and get the full 170-watt performance, but when on battery it consumes 65 watts. Accompany this with the ability to swap between integrated graphics and a dedicated GPU. You could have a laptop that can GAME hard when plugged in but have a really good battery life.
Laptops have done this since forever, albeit not as much for battery life and thermals as much as laptop batteries aren’t powerful enough to drive desktop CPUs running at full tilt.
I've been running my 7950x in 105 mode for over two months. I haven't had any issues. Like none. It doesn't get hot, my fans stay quiet and I haven't noticed a huge drop in performance. I love it.
What a great video. Just bought myself a 7950X to build a Linux workstation. I choose it over the 13900K because of efficiency concerns. I will definitely use the 105W Eco Mode.
I am impressed with the AMD ECO mode. You can dial the 7950X back to 105 watt or even 65 watt. And in those modes it will in worst case preform equal or better to 12900k.

I've struggled with not sleeping for a while, and I want to thank you. Now I just turn on a Gamers Nexus video and Steve's voice going on about watts, voltage and hertz puts me to sleep within 5 minutes! It's great, I start the latest episode and boop! Sleeping like a baby.
Would love to see an updated and deep dive on PBO with information and tips from AMD directly (or at least have them confirm your findings\data). Especially things like tuning Curve Optimizer for Ryzen 5000 and 7000
der8auer has interesting videos on power efficiency of Zen4 and 13th gen, in increments of 25W. For curve optimizer, -10 should be fine for everyone, and most should be able to do -15 or lower. My tip would be test idle stability, I can run -25 Cinebench (5800X), but crashes at idle unless I go to -15. Wish there was an option to boost idle voltage.
@@xeridea idle voltage already runs at 1.4-1.5 volts, not sure why you would want to increase that. If youre crashing at idle regardless of your CO settings you probably have plenty of other settings tuned poorly. I would do some more some research before giving advice.
@@four20thirdeye My idle voltage for 5800X is 0.95 volts, load is 1.15-1.25. Zen4 voltages are similar, or slightly lower. I have no earthly clue where you got 1.5V for idle. CPUs haven't ran at this voltage in ages. Even OC people don't even run that high without liquid nitrogen. Do you think CPUs run 2 volts under load? I suggest you hold back commenting altogether, you clearly have no idea what you are talking about.
I wish there was a bios where you can set a frec/volt curve like afterburner but for cpu in the bios and a option to set it per core that would be the best thing ever you would also have full control over the boost steps that way
I think Curve Optimizer in PBO does exactly that. You can adjust them per core, and there is even a tool called CoreCycler that you can use to test stability.
@@smallbutdeadly931 In the latest version of CoreCycler I've also included PJVol's PBOTuner tool that allows you to control the CurveOptimizer and power limits from within Windows itself, so you don't need to restart your computer and go into the BIOS to change the CO values during stability testing. It's a cool tool for quick testing, but of course it comes without any liability whatsoever. Additionally it seems to support CO values for the 5800X3D, which is disabled by default in the BIOS.
@@smallbutdeadly931 no i menan i like to set 0.8Ghz 0.9v , 1.5 Ghz 1.1v , 2.5Ghz 1.3v , 3.5 ghz 1.35v 4.5 Ghz 1.48v i want to also be able to edit the steps between like that not just the end points also every core is diffrent i testet pbo alot with 5800x but just check afterburner voltage curve settings exactly that customisablitty is what i want on a per core basis
Thanks for this very helpful content. I´m planning to build a 7950X system next week and as I will stick to air cooling (Noctua D 15) 105 W Eco is the way to go, stock settings are a pure waste of energy. With some luck in silicone lottery and a negative value in curve optimizer the results could get even closer between stock and 105 W.
I wish you could change the ECO mode without a reboot on the fly. That would be great. When I am just chilling with a browser and Discord and such, not gaming or doing work, I could put it to 65W mode. When I do work I could switch it to 105W mode or a custom profile.
Steve, I think many of us, sim games players, need more tests with games like Flight Sim, KSP, or big strategy games that have lots of activity on big maps. In a near future, having a big multi-threaded CPU might be a nice thing for those games, that are usually more demanding than average AAA FPS or online games.
@Gamerss Nexus, please retest by 65 watt in ECO mode but under volt. This can sometimes take advantage of the 5NM technology and result in massive gains in games. This will not work well in all core but can sometimes boost a couple cores extremely high and hold the boost. Thanks
When you look at the power efficiency numbers, you can see why AMD is doing so well in the server market. Tweaking the CPU for efficiency is roughly what is happening for a server that runs 24/7 and the difference with Intel is just massive. Though there's no Xeon or Epyc on the chart though but it was interesting to see.
Thanks this was exactly what I had asked for, focus on *energy* efficiency. I’m a professional and perf matters but heat and noise can become a higher priority above a certain level. The Zen 4 looks good in 105 W ECO mode.
I've been waiting for Gamer's Nexus to cover this. I'm one of those people who want to game without consuming an expensive amount of power. For those reasons, I don't usually buy Intel or Nvidia if AMD is being much more power efficient with their products.
Ah man, this was super interesting. Been waiting for this since the launch! Man, I know you guys probably don't have the time, but I'd love to see those same gaming comparisons w/ the lower-end CPUs in ECO mode. I'm wondering if gaming is affected just as much less even for the 7700X, for example. I'm assuming "yes," but it's really interesting and would be cool to know. Maybe when the X3D stuff comes out.
Eco mode is definitely impressive. I live in QLD, Australia and it can get pretty hot in my office. If I got this chip I'd be running the 105W Eco mode for sure. Nice review, as always.
I’m happy to see this testing borne out. I’ve been on a 7950X on my build running in 105W Eco mode and have been perfectly happy, especially since power where I live is closer to 40 cents/kWh all in. The one thing that I think might be worth it is that while I’m running an AIO cooler now, I know I could probably get away with a good double tower air cooler and be reasonably comfortable knowing that it should be able to keep up.
Pretty impressive on ECO mode gaming. What would really impress me is if AMD could shave the price some, not that I would build such a system, but for those who are wanting to.
It almost feels like 105 mode was the original design (especially with the temps) and then at the last minute they blasted it to higher and allowed the 95c temps.
This efficiency is incredible! AMD designed these things to basically auto-overclock out of the box, but you can easily just put 105W "Eco Mode" on and get almost the same performance! One has to wonder how severely impacted the 13900K would be in all of these same test at a 160Watt limit (the same Wattage that AMD's 105W eco-mode uses in all core workload)
So I tried limiting my 7950x by temp. Before I would get a cinebench score of around 6050-6150, tried tweaking a few things in bios, got 6240 but BSOD'd and stability went out. Went back to defaults with D.O.C.P and thermal limit of 85 degrees with fans only spinning up at around 80 degrees, before that total idle. I got a scores between 5950-6050, giving up at most 200MHz, most of the time I was only about 100MHz under stock. Ryzen Master was also showing that I was running at around 154W instead of the 170-230W... Yes, the selli g point of this CPU is unbridled performance I'd your cooling application is sufficient, but, when you turn it down to reasonable levels its efficiency is off the charts. Great job AMD!

This might sound ridiculous. But I suggest this: de-lid the 7950X, set the eco mode to 65w, and put it under LN2 to see how far the frequency goes.
@@exxor9108 Delidding wouldn't make any difference at all if you're already under LN2
Can you put eco mode to be 125W manually somehow and test it ? I saw somewhere on forum that some guy put manually at 125W, he got almost same perfomance as stck (-+1-2%) but temps are between 70-75c undel load with nzxt x73
Why u not testins AMD processor with AMD card with "AMD Smart Access Memory"? they says its +15% perfomance.
@@strehicabih5246 You can find the PBO values for any TDP with a simple interpolation on the values provided by AMD for 65, 105 and 170W. Following this, I set my 7950X to 125W TDP with the PBO settings : PPT=169W, TDC=125A, EDC=187A , this gives acceptable thermals (80°C max with high end air cooling) and performances even closer to the stock ones. Adding a slight undervolt using the Curve Optimizer setting, performances are even better than stock, with a 30% energy saving!
If targeting 125W TDP, 105 being 20 less than 125 and 65 less than 170:
PPT = 142 + (230-142) * 20/65 = ~169W
TDC = 110 + (160-110) * 20/65 = ~125A
EDC = 170 + (225-170) * 20/65 = ~187A

He should go to that cat sanctuary on Lanai that Dr. Ian Cutress went to (on his TechTechPotato channel a while back - "How to Pet 600 Cats"). Besides it being a cool haven for cats, it's on a Hawaiian island, so a great place to visit and unwind - and maybe visit the other islands as well.
All the shouting, man...
@Defective Degenerate Neither does being laid up in bed after collapsing from exhaustion, and in that scenario you have less choice in the scheduling.
Agree with those conclusions 105W definitely seems the way to go, but can we appreciate that chip in 65W mode managed to run all 16 cores at 4GHz and did it at only 19 degrees above ambient. That seems mad. The mobile versions of these chips are surely going to be monsters.
These cpus should have launched with 105w tdp and 170w should have been optional. That would have given much better press and 95*c issue wouldnt have existed
@@mtunayucer but YOU HAVE TO BE THE FASTEST... that's all the zombies care about.
Dragon range is supposedly going to be an around 60W TDP mobile chip with more than 8 cores. I wonder if they'll do something like a 7950HX that's basically the soldered version of this.
@@DigitalJedi dragon range is literally Ryzen 7000 desktop on mobile. The reason they can do this is because the IO die on Ryzen 7000 was built from the IO section of Ryzen 6000.
Think of it like this - people used to overclock back in the days to get massive gains in performance but now, company's have pushed the cpu to limit, there is nothing left to over clock BUT you can undervolt your CPU massively to gain efficiency instead of power.
This way, people who care about efficiency win, and people who care about mad performance also win
With all vendors pushing their products hard out of the box it seems opting in for efficiency is something that’s going to be more commonplace. These efficiency results bode well for Zen 4 mobile!
If you have 2 CPUs for the same price. One is less performance but more efficient, and one is less efficient but has more performance. The one with the most performance is going to outsell the one that's most efficient every time. "Efficiency" is almost exclusively an argument that a fanboy uses to defend their favorite brand when it falls short on performance. X is more efficient than Y, so X is a better per watt value. Meanwhile the rest of us are popping the IHS's off our CPUs and using liquid metal to run more power through them.
@@twiggsherman3641 efficiency is as important as performance because it creates headroom to rise performance by more power consumption
@@twiggsherman3641 For some users that's certainly the case, but not everyone. I'll happily take a 6% (at worst!) performance hit if it reduces total power consumption - which directly relates to both heat output, and electricity bill - by 40%. That's a nutty trade-off.
I fully respect enthusiasts wanting to push peak performance, even if they have to double their power (and heat) to reach it. Great for them! I'm enthusiastic about efficiency. I still want great performance, I just don't want a space heater in my room to get there.
@@twiggsherman3641 Well, ideally you want one that can do both! That way if you care not for the power use you can get max perf but if you care for power or heat production, you can still get good performance :)
@@twiggsherman3641 You mean like when Intel did the same back in the day:)? Sorry, but power efficient is still a thing.

There is also still the mobile half that does have to play the efficient game because of the battery limits we still have today.
105W seems like no-brainer for code compilation for the sake of maybe less noise. Thanks for benchmaking this stuff.
That is a really good point, noise is also highly affected with this as well!
Indeed, pretty sure i also prefer my cpu to be around 60C and not 95C lol
@@John__K well,, we do need a psychological shift on that cause before 100C was the most chips could handle long term but Zen 4 design can handle up to like 115C so 95C on these chips is more like 80C on older chips and for all-core thats not bad at all.
@@ImInYourBrains That's nice to hear.
However, 70~80C has been the long term safe~zone for cpus since like... forever.
Lab tests that try to simulate endurance of decades(hopefully decades and not just 3-5 years) are not enough for me. I need actual time passing of 5+ years under such conditions to get convinced that this doesn't affect their longevity.
Keep in mind that you don't get the same efficiency improvement shown near the beginning of the video for all workloads, i.e. for gaming there's probably no efficiency difference; they should've shown the average power consumption for each test alongside the performance numbers

@@tilapiadave3234 Still 15 (gas) vs 47 cents per kwh here.
I understand that GN is usually looking at hardware from a more traditional sense, hence constantly reminding that "300MHz all core". But the reason why many people look at these ECO modes is that the thermals and system noise concerns overcome the significance of the performance.
For me, it's not that you "lose 300MHz all core and that's a lot", but rather you "lose 6% of the core clock while reducing 50% power consumption". That's a truly impressive and disproportionate improvement. Personally, I care about these things because I am an ITX gamer nowadays, and there is a limited thermal budget for the system and a limited noise budget for my own sanity. My logic in looking at this is "what's the best performer at certain wattage that my cooling system can handle", and from that point, even a 20-30% weaker than stock 7950X is still within consideration. Although realistically, the best performance-to-cost ratio probably lies somewhere around a TDP limited 7700X or a 13700K for gaming.
From a gaming standpoint, what's your reasoning for the 13700k over the 13600k? IMO the performance gain is negligible to the price difference, and the 13600k outperforms everything in the field in a gaming sense except the other 13 series, and they don't lead by an incredible amount either. I almost don't even understand why the 7's exist anymore, with the 13600k being 14 core 20 thread, and having impressive workbench capability anyways. Seems like if you really needed something more from a workbench standpoint, you would just get a 13900k or 7950x as nothing else really justifies the price to performance difference.
not itx gamer, and I will take a 7700X @65/105W all day.
@@guy_autordie I think that's a great option as well. If you are doing it for the noise and thermals that's great. With the price difference over a 13600k if it was done from a more energy saving standpoint you'd have to leave it on nearly 24/7 for a year or use it for a couple to negate the $100 difference.
@@Wrenchingandnursing I just took 13700k as an example of something "not the flagship". I'm not that familiar with the 13th gen lineup, and the i5 may as well be more sensible than the i7 for gaming purposes with a limited power budget. I just vaguely remember that people were picking the 12700k as the sweet spot amongst the 12th gen lineup.
I think the mid-range SKUs still have unique spots in this performance vs package power chart. Say we set a 65W power envelope, for the 7600X to the 7950X the average W/core decreases respectively. I think the peak performance per W probably lies somewhere around 6-9W/core like the 105W 7950X, so for a 65W limit the 7700X might make the most practical sense, in that you don't lose 30% of performance like you do for a 65W 7950X, but still has the thermals under control. But that's a very rough guess and might as well be wrong since CPUs work in very complicated ways, and we've seen that the games don't scale very well with these Ryzen core counts, so maybe a 45W envelope 7600X is all you need for the best overall price-gaming performance-noise experience for going AMD.
Again I don't know too much about the Intel chips, but they seem to draw not that much power in gaming compared to some other workloads. My guess is that given a certain power limit, the 13700K might still be better than the 13600K, but maybe not by a huge amount, so the 13600K might as well be the most reasonable choice.
I was going to build a sane system to replace my positively ancient 1700X. Now you make me consider an ITX system with a 7950X (or X3D as my timing permits) that's been power limited.
I think dropping 30C is something most people would want and notice far more than the 5% slower CPU. With how fast the CPU is, I think it make sense for most users like that.
Yup. I want my computer to run cooler so my room doesn't get as hot from it. So I'm loving the eco mode
ECO mode in my asus bios makes my 5800x run with temps that made my jaw drop to the floor
if you'd just adjust the PBO curve offset or PPT limits manually rather than using the Eco preset, I'm sure you can get results within 1-2% of the top results while still reducing power and thermals massively. also, remember that it's not always just about the cost of energy. being able to half the output of your 700 Watt "room heater" is a blessing during hot summers.
Probably, similar thing for older 3000 and 5000 series, where manually adjusting the limits can get you pretty close to stock performance while also getting most of the savings of eco-mode.
Also don't forget about noise, not everyone has the nicest cooler and although they're much better these days the stock coolers are a bit noisy when they ramp up more than about 30-40%, so being able to maintain that more often is also a big benefit.
Americans are used to their air conditioning so they don't think about that.
@@Sunlight91 lots of Americans do not have air conditioning.
On 5800X, I can actually get higher than stock performance at slightly lower power with voltage offset. Probably similar with Zen 4.
Negative PBO curve offset seems stable for days then randomly gives me WHEA errors, it's not something a person buying for a workstation would want to use. One flipped bit might be hours or days of lost work.
I would love to see benchmarks between different CPUs (Intel and AMD) limited to the same power limit.

@@tranquil14738 The intel node is less efficient, its just certain benchmarks do better on Intel and therefore "trade blows" even though overall the AMD architecture is infact more efficient, especially with less aggressive boosting.

@@finestPlugins Japanese train stations would beg to differ.😁
Efficiency is something I believe is a mark of great generational improvement. All the companies can just blast powers each gen to get more performance but getting more performance or getting the same performance as last gen but consuming less power is something truly amazing these days.
Yeap. Amd and Apple are working wonders with their chips in this regard
AMD should intoduce a 7950E processor. It could be exactly the same but with default 105w tdp. If they saved the better quality binned dies for this the performance would be about the same as well.
Interesting idea! What does everyone else think?
@@GamersNexus i like it
@@GamersNexus I am not sure. I mean, would it be better than buying a regular 7950 and set the power limit to 105W?

65W Eco mode is more likely to be interesting for the datacenter where power costs, density and cooling matter a lot more.
105W looks like a great balance of speed and efficiency while 65W would be good for really big tasks where you can leave the computer on for an extended period of time (say overnight or out for a meal or whatever).
17:17 is impressive how the 7950X in 65W ECO mode performs better than the 5950X stock 8' vs 9.4' (16:16) and given the efficiency chart 11.8W vs 18.9W (15:15) if you want the maximum performance with the minimum power draw is an option, in fact with that efficiency I wouldn’t be surprise if we see 16 core CPUs in laptops soon

This is just what I was looking for. I'd be interested in seeing an undervolting video, as well. A comparison with the 13900K in an "Eco" mode and undervolted would also be interesting. I'm a big proponent of performance per watt.
I'd love to see a 13900K undervolted and maybe even downclocked a bit. I think you could shave maybe 400mhz off of the P-cores and still have a total monster of a chip. The E-cores can mostly be left alone, but taking them down to just 4.0ghz wouldn't hurt to bad either.
105w Eco mode + mild undervolt would further increase the efficiency, including scenarios where only single or few cores get stressed. With no loss in performance, except when all or most cores are stressed
Look forward to seeing these results for the full range of AMD and intel
Perfect timing! I was waiting for someone to do a deep dive on ECO mode...great video! I will be building a 7950X in the next month or so...and will run it in ECO mode. Makes a lot of sense not to drive the CPU so hard for such small gains.
Exactly my thoughts. I basically wanted better then ryzen 5000 performance but at least same efficiency. The 105 watt eco mode is even better then expected. It looses barely performance, few % tops, but it still 'crushes' the 5950x, win win situation.
Yeah it's what we were all expecting to find, ya? The 7950X is waaay outside it's efficiency curve at stock settings. I imagine if you could hard limit the PPT to 170w, that'd be where the efficiency curve peaks and you get the best performance for the wattage. Good testing guys! Love this! :D
It's funny how NVidia and Intel did EXACTLY the same. This is just for the WOW effect and also to please investors. The customers and the environment are dirt to them.
If you have a 7950X, you could try to enter the following manually into PBO: 186W, 125A, 197A -> This is exactly in-between AM5 105W cTDP and AM5 170W cTDP mode according to the table at 5:55. I bet you only see slightly lower performance in benchmarks only but won't be noticing ANY difference between Stock and this setting. Also, it will probably still lower temperatures down by 20 Kelvin, which might even result in higher clocks (and thus even higher performance) depending how constrained your cooling solution is!
If you want 125W TDP, which is 20 higher than 105, the diff between 105 and 170 being 65:
PPT = 142 + (230-142) * 20/65 = ~169W

Thanks for all the hard work Steve & GN team. As a graphic designer with a 6 year old entry-level CPU, this has felt like the year to start fresh with AM5, and I'd been waiting on eco-mode reviews to pick between the 7950 or 7900 and find a sweet spot that works for me so this gives me a clear answer.
Just upgraded to 7700X yesterday and met with absolutely fans blasting with first benchmark because of 90+ temps. But I knew that before buying.
After enabling ECO mode, which for 7700X would be 65W as it is 105W TDP stock. Huge difference in temps(Barely hear fans as temps stay around 60) and decent power consumption. And while it is not same CPU, I dont expect huge drop in performance with 7700X either.....eco mode is the way to go.
I somewhat understand the need to extract everything out of the CPU while sacrificing power and thermals...because performance sells. At the same time, they almost lost my sale if it wasn't for the eco mode, I just wish they mentioned it more.
Although it was kinda simple option in the bios if you search it and I believe Ryzen master has it also. I didn't actually know that. After reading couple articles I though you had to input numbers in the BIOS/PBO and thats what I first did.

Best of luck to you mate
So basically the 105W ECO mode runs at about 60% of the power and achieves almost the same performance as stock. Almost the same productivity performance as 13900K but consumes half the power.
And generates massively less heat
The problem is you can also turn down the 13.9k and get better performance.
@@WaterZer0 But the point here is, this is a toggle option, while Intel might be more complex, if it was a toggle, GN would test it as well.
@@WaterZer0 you need to do custom tuning
@@WaterZer0 Zen 4 can also use curve optimizer. Your argument is moot.
My personal interest in this is that I donate my spare CPU cycles through boinc when I don't need them. For that, I limit my (4800H laptop) CPU to 20W using power saving mode. In that case, the efficiency is absolutely worth it!! Balanced mode is 10% higher frequency for 75% more power and I don't even bother with High Performance mode. I just suspend boinc when I want to use my computer quickly!
For a minute there i thought it was the 7900XTX you were benchmarking, i was like only GN could do something like this this early hahah
FR this is third time AMD launched 7000 series, there will be confusion for times to come...
Why did they do that, idk. Itsenot like they ran out of numbers.
hahaha, I had to check and make sure I didn't write that in the description or title by accident!
To be fair, Steve _did_ take the 7900XT(X?) with him in the last video. 😬
I use "handmade" eco mode on my 5950x. I could immediately feel and see the difference in room temperature (12m² room ) at the end of my workday as I am running VMs, containers and compilers the whole day long
Me too for my 5900x! When it doesn't make the room warm too. I wished there were more videos about how to run more efficiently than power at any cost.
Same, but I like turning it off in the winter 😆
@@futuza haha. My house is isolated too well. In winter it's perfect
Wasn't the 5950x a super 'cool' cpu? I looked up some tempts to compare to the insane 7950x, and they were mostly 65-80°C (defintiely not 90°).
@@Matti6950 Yeah, but like 65°C is definitely going to warm your room up XD.
Keep in mind the 65 watt mode is probably for mini atx systems where you can pair it with a small rtx a4000 or a4500 or similiar card so it would also make for a tiny workstation that could be tucked away in the corner of your mancave. You could use a itty bitty air cooler or 120 mil radiator and take up a fraction of the space a tower would and still run cool and quiet by adjusting the fan and power consumption of the small workstation cards.. I'd love to see some tiny workstation builds with this cpu
HP or Dell usually try in their workstation lineups, but forget to configure the TDP limit accordingly and make the whole thing fry itself in two years. I can only hope it'll get better, eventually...
Would love to see how the R7 5800x3d fares in comparison in all those games! Great video, thanks for all the infos team!
The answer is “fast enough”. Realistically unless you have a ridiculous multi 4K monitor setup, just about any mid range CPU is fast enough for gaming, even at high refresh rates. Once past about 120fps, you are beyond the limits of human biology anyway, any difference is barely perceptible. These high core count CPUs only make sense for compute workloads. For gaming you are just paying extra for bragging rights. If you are a gamer and already have a decent AM4 setup, the 5800X3D will do you fine for several years to come.
@@chrisward000 4K is less noticible than 1080p, where you are CPU bound to hit the upper fps limits at 200fps+. Once you're running 1440p or higher the eco mode is plenty and 1% lows are more important so you don't see fps drops from your fps g-sync cap.
5800X3D , WAY over-priced EXTREMELY overhyped waste of sand
@@tilapiadave3234 A bit overpriced at launch, but recent discounts made it a good option for anyone on AM4 with Ryzen 3000 or older. I would not put one in a new build, but way cheaper than a full system upgrade to go to Ryzen 7000 or Intel.
@@chrisward000 the 3d is basically the same as the 5800x and 5700x at 4k so not a good example even at 1440p its rarely of note. You mostly want it at 1080p as it's a monster for that for those on am4 socket.
Was looking for more CPU testing. Should be good
Back then it was overclocking, now it's tuning for efficiency. Weird times we live in! I'd pick the 105W mode all day over stock if I had a 7950X.
Yeah, undervolt is the way to go man.
I would love to see eco mode vs setting PPT and CO manually. Great review!
I do a lot of Blender type workloads. Stock my 7950x was just way too hot == noisy. Set it to 105 eco and lost maybe 5-7 percent performance maximum. But my machine is relatively quiet now and energy costs have gone through the roof so that's better too
What are your idle, medium low (games) and all core load temps? I'm insanely curious what temp it will be (95°C is unacceptable to me - biggest reason my 3570k Intel lasted 8 years, i do not trust a perma 95°C cpu to make that) but if the eco mode shaves op permanent 10°C in cinebench, all-core loads (and much more in others), that would make me accept it. If it shaves off 20°C while using something like Noctua cooler, I would finally stop doubting the ryzen 7000 series (except for DDR5 and motherboard prices).
@@Matti6950 medium (RUclips and other bits) below 50c. Rendering up to 70c. Noctua D15
@@kw7865 Thanks a lot, that seems totally what i would fine acceptable (much better then 95°C). Friend is recommending me strongly the Noctua ND-12U, over Noctua ND15 but both are on my shortlist.
A small amount of under-volting is what you want. You can get the thermals and power draw down significantly, and the "overall" performance up (due to absent thermal throttling).
It needs a PBO2 'tune'. Ideal power is close to stock, but just a bit down.
This actually helps a ton in deciding whether to even bother with Ryzen 7000. 105W Eco being both faster AND more efficient than my current 5950X is very tempting. I'm still waiting for the 3D version, though
First thing I did when I got my 7700X was PBO undervolt by 25mV and reduce the power limit to 85W and the performance was basically the same as stock, but with much lower temps. I was pretty happy with that.
I just ordered 7700x & would try & see.. the reviews says it's around 150w max at 100% usage..
With your 85w, it's like 40% power less power for nearly the stock GHz speed? not bad
For me, I'll try to go to 105w (undervolt) with slight OC (might be able to get a better boost?)
BTW what Mobo did U get? all the B650 I found was expensive.. Asus B650 TUF is $240 while MSI Tomahawk is $270
I like Tomahawk because it's have better thermals & more sata 3 ports.. but the TUF price is better
Feels hard how my B450 Tomahawk was $100 in 2019, while this new Tomahawk is $270 (2.7x increase)
And 48 watts at idle? Vs Intel at 14 Watts ,,, hmmmm REAL WORLD AMD is far FAR less power efficient.

@@djashjones Did you just call Steve's video rubbish?
Have they ever thought to factor in the effect of Steve's hair falling into the PC cases and how it could affect airflow and temps? I mean, dude has a lot of hair! 🤣
I'd actually love to see GamersNexus do a dedicated deep-dive video on PBO curve optimizer for the new Ryzen generation. Since a lot of Ryzen users tend to optimize their boost clocks via an UNDERvolted (negative offset) PBO curve optimizer, I'd love to see GN revisit the topic of Ryzen's curve optizer and achieving good clock numbers that way while reducing power.
I actually had a 5950X running in Eco mode but mostly because it was installed in a small form factor system. Only took a hit in multi core performance surprisingly.
Same with my 5900x. Single core performance actually increased slightly in Eco Mode.
That makes sense. Boosting only 1 of 16 cores should stay well within the power limit when the other cores aren't loaded heavily, and of the other cores are clocked lower to begin with because of the ECO mode, you can actually send more power to that single core due to the additional thermal headroom.
I noticed something similar when I was undervolting my 9750HK laptop. I lost about 10% on multi-core performance, but gained 9% on single-core while never touching the 135W power limit. I actually stayed below 120W even in a full Cinebench R23 10-minute test.
@@glosan9516 Do you use the default Eco mode or do you have a handmade one? I am running (95W TDP): 128W PPT, 80A TDC, 125A EDC but hoping to see if anyone finds a better balance based on the efficiency curve like what Debauer showed for NVIDIA.
Basically: If you have a AMD Ryzen 9 7950X, run it at 105W eco mode, for wallet, longevity and thermals.
makes sense. Though if I was gaming I would just run it lower it seems to the 65w mode.
The new camera, lens, and/or LUT on the vids is looking great! Love seeing the evolution of the channel. Keep up the amazing work!
I had no idea how bad the power efficiency was on the fx 9590. 200 watts on a 4 core 8 thread processor is honestly insane to think about now.
Surprising results, but at the same time not too surprising results. This is just how CMOS works: Power consumption scales exponentially compared to switching frequency. The 105W results, however are very surprising. Thanks.
So, TL;DW, 105 eco mode is for productivity, 65 eco mode for gaming, and stock if you want to compensate for something, have a seriously intensive CPU workload, really love the sound of fans at 100%, or you're too cold.
Great breakdown, as always, from Tech Jesus.
The 65w mode is perfect for making a professional workstation the size of a shoebox. Most artists are freelancers, and the desire for smaller and lighter weight workstations is real.
105w mode can be used for cost saving. You can get a cheaper cooler, or more likely not replacing an existing cooler. It may also allow you the extra headroom on an existing power supply to allow for a GPU upgrade, without requiring a PSU replacement.
I have been undervolting/limiting basically everything lately. Those last 5% for the price of 30% are not my thing in the current market and noise preferences.
This is my first time watching on my monitor at 4k and wow the new cameras are paying off, Amazing DoF, RT, Steve with Global illumination is just tooo real.
Thanks Steve!
What is your monitor?
@@syntrx8185 LG OLED 48 C2. I normally watch on my phone haha.
Lot of numbers instead of that mumbo jumbo, one of the best take on the subject I've seen on YT, thx!
As an audio professional, 30 degree drop while staying with 90-95% of stock performance is HUGE. Less heat means less fan noise, which is a big deal when the thing that makes you money is your ability to listen. What an awesome CPU
Ecomode could be well worth it in select circumstances, as power cost approach the cost of the cpu itself. With 170W saved in 65W ECO, with 24/7 operation and power costs at 0,4€ (not unseen in Europe right now) the CPU would gulp 595€ in just a year. At the end a 100% utilization is unlikely though and opportunity costs can be significant. 105W ECO could be a good tradeoff for highly efficient computing and lower running costs.
With a 25% perf drop you lose 1000€ (Cpu+Mb)* 0,25 = 250€ in opportunity costs (roughly), so you need to redline your cpu but you could save maybe/roundabout 300€/year.
I power limit my 4090 to only 80% and don't feel bad at all. It performs light years above my 3090 Ti still. I undervolt my 5900X as well and it does better in performance and temperatures.
I UV 5800X somewhat out of necessity, running Hyper 212 Evo cooler, and prefer under 80C for video transcodes. I am able to get essentially stock performance though. They say 95C is fine, but I would rather have more safety margin.
What is total system power consumption?
@@Praxss, I've never measured it before, but the 4090 alone is less than 400 watts when gaming/running benchmarks.
When you realize that the 7950x is beating or closely competitive at 105watts vs Intel 13900K's 240 watts that speaks volumes for efficiency.
I kept looking at 0.1% and 1%. It looks like stock is doing quite a lot better there and 7700x was doing by far the best in a lot of those - the “top” CPUs in some of those were dropping under 60fps for 0.1%.
I actually really think eco mode has a place in the laptop market. Imagine being able to plug in your laptop and get the full 170-watt performance, but when on battery it consumes 65 watts. Accompany this with the ability to swap between integrated graphics and a dedicated GPU. You could have a laptop that can GAME hard when plugged in but have a really good battery life.
Don't laptops already do that?
Laptops have done this since forever, albeit not as much for battery life and thermals as much as laptop batteries aren’t powerful enough to drive desktop CPUs running at full tilt.
65W is quite a lot for battery. 15W to 25W would be better in this case.
No proper laptop has the cooling for a 170W CPU.
170w on laptop? LOL
Considering the cost of making electricty, offgrid users will surely appreciate the 65W mode.
So it's good that the choices are there.
I've been running my 7950x in 105 mode for over two months. I haven't had any issues. Like none. It doesn't get hot, my fans stay quiet and I haven't noticed a huge drop in performance. I love it.
would u recommend 65W if I wanna do render 24/7? What temps are you hitting and what MOBO would you recommend?
What fans do you use though?
I’ve been intentionally limiting perf on my 5900X + RTX 3070ti. It’s addicting.
Great video, it'd be even better if you can test manual pbo2 tune with curve optimizer and custom ppt, edc and tdc limits.
What a great video. Just bought myself a 7950X to build a Linux workstation. I choose it over the 13900K because of efficiency concerns. I will definitely use the 105W Eco Mode.
I am impressed with the AMD ECO mode. You can dial the 7950X back to 105 watt or even 65 watt. And in those modes it will in worst case preform equal or better to 12900k. If you need the max power you will be able to flip a switch and unlock the full potential. For my work I see that as very tempting. As you can select to have a docile office 65 watt CPU office PC. Or a semi HEDT PC in the same package
I've struggled with not sleeping for a while, and I want to thank you. Now I just turn on a Gamers Nexus video and Steve's voice going on about watts, voltage and hertz puts me to sleep within 5 minutes! It's great, I start the latest episode and boop! Sleeping like a baby.
Would love to see an updated and deep dive on PBO with information and tips from AMD directly (or at least have them confirm your findings\data). Especially things like tuning Curve Optimizer for Ryzen 5000 and 7000
der8auer has interesting videos on power efficiency of Zen4 and 13th gen, in increments of 25W. For curve optimizer, -10 should be fine for everyone, and most should be able to do -15 or lower. My tip would be test idle stability, I can run -25 Cinebench (5800X), but crashes at idle unless I go to -15. Wish there was an option to boost idle voltage.
@@xeridea idle voltage already runs at 1.4-1.5 volts, not sure why you would want to increase that. If youre crashing at idle regardless of your CO settings you probably have plenty of other settings tuned poorly. I would do some more some research before giving advice.
@@four20thirdeye My idle voltage for 5800X is 0.95 volts, load is 1.15-1.25. Zen4 voltages are similar, or slightly lower. I have no earthly clue where you got 1.5V for idle. CPUs haven't ran at this voltage in ages. Even OC people don't even run that high without liquid nitrogen. Do you think CPUs run 2 volts under load? I suggest you hold back commenting altogether, you clearly have no idea what you are talking about.
and ^thats^ why I want some information from AMD
The savior for SFF builds.
I like it when you do these kind of Videos. They somehow are so much lighter on my brain. Well Done. Thank You.
It is surprising eco mode doesn't lose hardly any performance, especially in games where it's near identical performance.
Most games barely touch the CPU anyway, so it won't matter if they're not getting full juice.
@Defective Degenerate where did you see performance lost for 105w
I wish there was a bios where you can set a frec/volt curve like afterburner but for cpu in the bios and a option to set it per core that would be the best thing ever you would also have full control over the boost steps that way
I think you can do that with the Ryzen Master software (or Intel's XTU for their CPUs).
I think Curve Optimizer in PBO does exactly that. You can adjust them per core, and there is even a tool called CoreCycler that you can use to test stability.
Read about the AMD Curve Optimizer!
@@smallbutdeadly931 In the latest version of CoreCycler I've also included PJVol's PBOTuner tool that allows you to control the CurveOptimizer and power limits from within Windows itself, so you don't need to restart your computer and go into the BIOS to change the CO values during stability testing.
It's a cool tool for quick testing, but of course it comes without any liability whatsoever.
Additionally it seems to support CO values for the 5800X3D, which is disabled by default in the BIOS.
@@smallbutdeadly931 no i menan i like to set 0.8Ghz 0.9v , 1.5 Ghz 1.1v , 2.5Ghz 1.3v , 3.5 ghz 1.35v 4.5 Ghz 1.48v i want to also be able to edit the steps between like that not just the end points also every core is diffrent i testet pbo alot with 5800x
but just check afterburner voltage curve settings exactly that customisablitty is what i want on a per core basis
ECO mode blew my mind and my stock temps were already very low compared to others online.
Thanks for this very helpful content. I´m planning to build a 7950X system next week and as I will stick to air cooling (Noctua D 15) 105 W Eco is the way to go, stock settings are a pure waste of energy. With some luck in silicone lottery and a negative value in curve optimizer the results could get even closer between stock and 105 W.
Would be great to have a physical button on a PC case that instantly would switch between stock and 105W Eco. Maybe label it “Turbo”…
Boomer spotted!
Meanwhile I grew up thinking it made things faster, like turbo buttons on game controllers.
What a novel idea! Just for shit and giggles when it's on make it use the eco mode, too.
I wrote an AutoHotkey script to switch Windows performance profiles for essentially this effect!
iunderstoodthatreference.jpg
I looked at thumbnail and my first thought was 'um, why it doesn't support winamp'?
rip...
I wish you could change the ECO mode without a reboot on the fly. That would be great. When I am just chilling with a browser and Discord and such, not gaming or doing work, I could put it to 65W mode. When I do work I could switch it to 105W mode or a custom profile.
Steve, I think many of us, sim games players, need more tests with games like Flight Sim, KSP, or big strategy games that have lots of activity on big maps. In a near future, having a big multi-threaded CPU might be a nice thing for those games, that are usually more demanding than average AAA FPS or online games.
I prefer to roll coal with my CPU.
@Gamerss Nexus, please retest by 65 watt in ECO mode but under volt. This can sometimes take advantage of the 5NM technology and result in massive gains in games. This will not work well in all core but can sometimes boost a couple cores extremely high and hold the boost. Thanks
When you look at the power efficiency numbers, you can see why AMD is doing so well in the server market. Tweaking the CPU for efficiency is roughly what is happening for a server that runs 24/7 and the difference with Intel is just massive. Though there's no Xeon or Epyc on the chart though but it was interesting to see.
Thanks this was exactly what I had asked for, focus on *energy* efficiency. I’m a professional and perf matters but heat and noise can become a higher priority above a certain level. The Zen 4 looks good in 105 W ECO mode.
I've been waiting for Gamer's Nexus to cover this. I'm one of those people who want to game without consuming an expensive amount of power. For those reasons, I don't usually buy Intel or Nvidia if AMD is being much more power efficient with their products.
Check out derbauer's video on 13900K launch day
I just want full power 100% of the time.
That's definitely an option... just load up Prime95 and let it replace your heater!
Don't forget to spice things up with smallest FFT
Do you even know if you can utilize it meaningfully?
IMO amd should've released both ryzen 9 in the 105w configuration and let the users overclock beyond that as they see fit.
Ah man, this was super interesting. Been waiting for this since the launch! Man, I know you guys probably don't have the time, but I'd love to see those same gaming comparisons w/ the lower-end CPUs in ECO mode. I'm wondering if gaming is affected just as much less even for the 7700X, for example. I'm assuming "yes," but it's really interesting and would be cool to know. Maybe when the X3D stuff comes out.
Thanks for the amazing content Steve and team!
6:13 cheeky Steve... probably got more info behind the scenes when he went to the AMD rdna3 reveal
Eco mode is definitely impressive. I live in QLD, Australia and it can get pretty hot in my office. If I got this chip I'd be running the 105W Eco mode for sure. Nice review, as always.
Waited for this discussion for a month now!😊👍
Glad to finally see a Intel X processor in your list. Thank you Sir.
I’m happy to see this testing borne out. I’ve been on a 7950X on my build running in 105W Eco mode and have been perfectly happy, especially since power where I live is closer to 40 cents/kWh all in. The one thing that I think might be worth it is that while I’m running an AIO cooler now, I know I could probably get away with a good double tower air cooler and be reasonably comfortable knowing that it should be able to keep up.
This is really timely. Thanks!
Have you recently upgraded your lightning/+ or camera setup. If not still very pleasant for my eyes, keep the good work coming! Thank you.
Pretty impressive on ECO mode gaming. What would really impress me is if AMD could shave the price some, not that I would build such a system, but for those who are wanting to.
Amazing no mention of idle usage or real world usage for those needing pc on 24×7
It almost feels like 105 mode was the original design (especially with the temps) and then at the last minute they blasted it to higher and allowed the 95c temps.
I thought Steve's next video would be the 2nd 1:00 am, but hes early this time.
This efficiency is incredible! AMD designed these things to basically auto-overclock out of the box, but you can easily just put 105W "Eco Mode" on and get almost the same performance!
One has to wonder how severely impacted the 13900K would be in all of these same test at a 160Watt limit (the same Wattage that AMD's 105W eco-mode uses in all core workload)
So I tried limiting my 7950x by temp. Before I would get a cinebench score of around 6050-6150, tried tweaking a few things in bios, got 6240 but BSOD'd and stability went out. Went back to defaults with D.O.C.P and thermal limit of 85 degrees with fans only spinning up at around 80 degrees, before that total idle. I got a scores between 5950-6050, giving up at most 200MHz, most of the time I was only about 100MHz under stock. Ryzen Master was also showing that I was running at around 154W instead of the 170-230W... Yes, the selli g point of this CPU is unbridled performance I'd your cooling application is sufficient, but, when you turn it down to reasonable levels its efficiency is off the charts. Great job AMD!
