i have got a gtx 1070 undervolted and underclocked pulling around 85w down from the stock 140w if i leave the card at stock, plus my old haswell i7 pulls around 50w during gaming. From the wall i measured 175w total power draw while running dying light 2 which i find to be pretty damn efficient for the performance of the system as it runs great at 1080p and i only lose about 7fps typically.
@@JudeTheRUclipsPoopersubscribe yea Pascal was nuts when it came to power efficiency, even the 1080 (the launch flagship) still only needed a single 8-pin, which I still find impressive
@@exaltedb it's also amazing how much you can tweak pascal cards. I mean I managed to get -200mv and dropped the core down 100mhz to 1760mhz and it's stable and running great and barely lost any performance.

@@FriENTlyFire Yeah dude The 2600 was a nice budget CPU at the time, but I upgraded from one to a 5600 about 2 weeks ago and it gave my RX 570 a massive boost. Considering the 6600 is twice the performance of an RX 570, you'll see an enormous improvement by making an upgrade.

Using the laptop screen I can probably save some more power and use 1080p more. Just have to see if I can change the screen for 144hz to 60hz to save more power
yep, your 2070 super max q is no less efficient than these desktop GPU-s. 3000 laptop cards are even more efficient, so this guy was wrong when he was talking about "the most efficient GPU on the market" because that's the laptop 3080 ti.
It's worth noting that NVIDIA and AMD report power usage differently through software, so it's not really 100% comparable. It's better to have a physical measurement of power draw using something like the NVIDIA PCAT instead.
Exactly! Many people don't realize amd is pulling more then the let on! I find it funny the real knowledgeable have all explained how it works. Yet people still want to act like ita 200watts to 250watts eveb at the high end.

From my experience, using RX 6600 XT and RX 6800. You have to set the minimum frequency to 100mhz lower than max value. The frequency keeps fluctuating if the min is kept at stock value (i think it was 500mhz). Do not worry, on idle, it will not stay at the min frequency, it will downclock to very low value.
No. Best performance is somewhere in between. Idk why, but amd overclocking is just wierd. (Source: did a lot of tinkering with 69xt, from 180 watts, to 500+)
@@DawidDoesTechStuff on my 6900xt efficiency improved when not hitting power limits. Lowering max clock helps too. I ran it at 180w with significantly more than stock performance. RDNA 2 OC is like voodoo magic 🤦♂️. Let's hope rdna 3 is a bit less wierd.
I think you weren't getting any higher clocks when moving the slider because you were hitting power limit, if you moved the power limit slider to the right, it would let the card reach the clocks you want it to, but then again that's against the point of the video because you're increasing wattage for minimal gains probably.
@@DawidDoesTechStuff There is 1 more thing you can do to squeeze the absolute limit of the card. Take out those RGB lighting on the GPU . It shares the same power budget with the entire card. Since your Nvidia A2000 doesn't have any lighting, the RX6600 should be the same too.
@Dirk Jefferson Nah, if you give the card more power and voltage it will actually reach the clocks you set in Wattman, though the performance you gain with those overclocks compared to the extra power you're using isn't all that great, as with any overclock. The highest I had my 6600XT run at was around 2900 Mhz on the core before it got too unstable with a SPPT Softmod.
I loved the 5000 series GPUs because you could push a 5700XT to be faster than a 2080 and use 250w. Or you could basically run fanless at 60w on alot of older games
Funnily enough they talked about this on DF direct the other week and they concluded that software optimisation is the fly in the ointment with trying to quantify this sort of thing!
Did you try limiting the clock speed on the 6600 to -20? In my experience on a 5700XT, that cuts the power draw roughly in half for about 80% performance, no voltage tweaking necessary.
@@DawidDoesTechStuff heh.. Funny it's completely the opposite answer of what I got, when I said the same thing, except it was 2100 mhz, instead of - 20%, however the same point. Don't forget to undervolt, while you underclock to get even better results 😉.
Ooo goodie! Don’t expect miracles; the 6600 isn’t pushed as hard from the factory as the 5700XT was, which means it’s closer to optimal efficiency already.
@@gismo3564 What I told both of you is correct. I did try manually lowering the core frequency while undervolting. I set the card to around 2300Mhz to try and get any voltages below 1100mv to stick, but the card still kept crashing. Although when I set the voltage back to 1100mv and continued testing, I reset the core frequency to default. (In game it kept hanging around 2400Mhzish, regardless of what I did to the core frequency slider. The driver seemed to just ignore any manual core frequency input) So I didn’t test performance/power draw with a manually lowered core clock, I just used it to try and get a more aggressive undervolt stable which didn’t work. Haha! Hopefully this clears it up. 😂
This video opens the door to another question... Could a RX 6500 XT be power-throttled to the point where it could be powered exclusively by the PCI-X slot?
If I remember correctly PCs won't boot with a GPU that are not connected to power if they normally need power cables. Would be nice though if every GPU had a 75W mode. Though it wouldn't surprise me if a 75W 3060 wouldn't perform roughly the same as the MSRP-wise more expensive A2000 as both chips are essentially GA106 and we can't have that. (75W GA107 3040 to replace the 1650 pls...)
i have a sapphire rx6600, and it's night and day compared to my 3050. with the undervolt i've put on it, it never throttles inside of a deskmeet b660, and i have to run benchmarks to even get it above 78C. it's a great card, the only thing i miss from NVIDIA is stability and custom resolutions - the 6600 has a tendency to crash when upscaling and alt-tabbing.
it is what I've been saying since last year when I got myself a 6600xt. But not a single person in the comments would believe me, because no big youtuber talked about it. the 6600xt is the best card when it comes to FPS/efficiency
Also with amd's overclocking, your clocks will be limited by the power limit ie( if your clocks are set to 2700mhz, but your hiting a power limit, the clock wont go up until you raise the power limit) as a side note you can use a tool called morepowertool to raise the max and min on the sliders
Reminds me of the time when I was messing around with RX580 and 5700XT. Those would undervolt like crazy and ramp up the efficiency quite a bit... but it would also come with some framerate hit if I tried to maximize efficiency (which was fine, as they usually didn't affect the gameplay). Still couldn't catch up to the 1660 and 3060 I have owned though, which was trickier to undervolt but incredibly efficient from the get go.
Actually limiting the max frequency in Adrenaline gives you a way bigger reduction in power consumed than can be set with the power slider, and for just a moderate decrease in FPS, if it's efficiency you seek...
Power limit slider is useless in these cards. You need to reduce the max frequency of the card to e.g. 2200 MHz and you start to see the power usage drop. You lose 10% performance but your power consumption will drop a lot more. Also the minimum frequency should be 100-200 MHz less than the max frequency to keep the clocks more stable.
Yep, the RX 6600 is quite impressive from a performance per Watt perspective, though if you want the best RDNA2 card in that respect you should check out the RX 6800 non-XT. According to the powertests Igors Lab did the non-XT Version of the 6800 basically consumes power like a 3060ti (so around 200-210W board power stock, though with a bit of undervolting it can get even lower then that) while, depending on the game, performing like or even above a 3070ti. So in terms of FPS per Watt the RX 6800 non-XT is almost twice as efficient as any other card according to his charts. Edit: One tip for Over- and Underclocking AMD cards, keep the Core sliders for min and max Frequency within 100 Mhz of each other, otherwise they won't do much because by only moving the max slider you're basically just telling the card the upper boost limit but due to the min slider beeing too low it won't actually try to boost that high.
I remembered this video recently and decided to do my own testing on how to improve GPU efficiency. Only I went about it a completely different way that paid off big time! I dialed down all the sliders in the Radeon tuning section to their minimum and then at the lowest voltage I decided to slowly increase the frequency back up until I reached as far as I could go while still being stable. Once you reach a certain point you'll have to dial the power limit back up to continue on. Just keep the voltage at minimum! Using this method on my reference RX 6800, I was able to achieve 85% of the stock frequency! This gave an over 25% improvement to performance per watt in FurMark and as much as 60% in games! Theoretically speaking, I imagine this margin grows even greater with the more powerful the GPU you use. This is considering how number of GPU cores and the larger the memory bus matters more than raw clock speeds. I'd love to see this tried on a 7900 XTX!
One thing I've found with cards that are tricky to effectively limit the power on is that if you limit the frame rate instead, you can get satisfactory power reductions. Limiting the frame rate to the same level as the A2000 may have resulted in a closer match, though it looks like the 6600's advantage in GTA V wouldn't give enough headroom for this to make much of a difference.
I am wondering if underclocking & even more undervolting will bump the efficiency of the RX6600 at all, as AMD cards are clocked very high to be competitive, but their sweet spot frequency for efficiency could be much lower (guessing under 2000Mhz). Additionally, if the card is slightly underclocked, it might not need a high memory frequency to keep it well fed with data (memory underclock), which could in turn make its efficiency even better.
RX 6600 is bottlenecked by the power limit, so overclocking does not make any difference. If I unlock my power limit to 120% I easily gain another 10% fps. So when undervolting, instead of reducing power consumption, you're actually increasing the clock speeds. What might actually make this card more efficient is an undervolt combined with underclocking
Hi Dawid, I have been watching your LP GPU video's and I was wondering if you could help me find a more efficient Graphics card for power than the a2000. I live in an area where power is incredibly expensive, so I have never had a GPU. I have been using UHD intel graphics my entire gaming lifetime.
The a2000 is very expensive as it costs more than a 3060ti and less than the 3070. Do the math to figure out how long you would have to keep your computer on before the cheaper graphics card becomes too expensive due to power. The quadro T1000 is expensive but uses 50 watts A used 1050ti is cheap but uses 75 watts just like the a2000 The rx6400 is new and cheap, but without pcie gen 4, its bad
MSI's Mech 6600 vbios is practically identical to this one, and i think it's already undervolted as far as they're comfortable with - remember this card is supposed to be 132W not 100W. compared to my EVGA 3060, the efficiency of this thing is just absurd. the 6600 XT and 6900 XT are also incredibly efficient if tuned well.
Using More Power Tool (MPT) you can lower RDNA2 voltage to 650mV and clocks to around 1400Mhz, this is where there is the most efficiency in my experience. Almost double the stock FPS/Watt. You also can extend the power limits lower and higher with MPT. You also need to test power consumption at the wall, as others have pointed out. I'd love for this to be expanded because I've done some testing with 6800xt, 6700xt, and 6800m, all to see peak efficiency for off grid gaming.
When it comes to tuning rx 6000 gpus, it seems that setting the maximum and minimum clock at 100mhz apart (for example 2500min and 2600max) improves stability a fair bit. It lets you do a bit more in term of overclocking or undervolting before the gpu becomes unstable. The youtuber "ancient gameplays" has a pretty comprehensive video on this. Also, it is worth noting that when it comes to power efficiency, it is highly beneficial to underclock the gpu. Every gpu that I have tested so far was clocked pretty significantly past its efficiency window. Reducing the clocks by for example 100mhz leads to a significant decrease in power consumption, while not having a proportionally negative effect on fps. I tried this on a Sapphire 6650xt nitro+ which can draw up to 203 watts in performance mode. I paired it with a 12400 and measured power draw at the wall, since according to Igors Lab the read outs of programms are pretty inaccurate, especially for amd. Tldr: With undervolting and underclocking, my total system power usage went from 265 watts average to 158 watts average while loosing arount 11% performance in the heaven bench mark. Sucks to loose performance, but good to know you can tweak cards towards efficiency pretty far with very little effort. Would be awesome though to get a video of you using the morepower tool to reach max efficiency :D
I'm surprised about how much life I've gotten out of my five year old GT 1030, it will not perform on low graphics at all for anything like Battlefiled or Halo Infinite Fortnight however it'll do just fine for Fallout and Elder Scrolls games. I find multiplayer games incredibly boring and stale even compared to a 10 year old game such as New Vegas so an old entry-level card is all I currently need until I have the need to use a more powerful card.
Wow nice i also have a gt 1030 its actually very nice to at least squeeze out some horsepower from that lil baby, ill stick with it until i get unbroke and buy a new 1060 or higher
@@seven7000_ It's a fun little card, I run mine on an old small form factor HP with an Xeon.

Was definitely worth the $70 I spent back in '17.
Undervolting AMD cards is a whole other situation that I feel like you havent really figured out. I would suggest you have a look at someone that usually playes with SFF. Perhaps Optimum Tech could help you? I would walk you through it but I'm not famous. Otherwise, as always I enjoy your videos and appreciate that you continue to have interesting content. Prost
Perhaps they're already pushing the 6600 as much as they can on the power envelope it's at. Granted, that's not the nicest model, so it's possible it's not got a great binning to begin with.
Very interesting video! If you’re doing a follow-up, could you also overclock/undervolt the A2000 further? Also I think the 6600 XT will actually be more efficient if you can undervolt the crap out of it with morepowertool.
Maybe do a video making a super efficient gaming pc? Super efficient CPU GPU combo and an appropriate screen to match? Really enjoyed this video though !
You should try with a much higher end card. At lower power draws the more cores (CUDA or your regional equivalent) will give you more performance per watt - which is why high end laptop GPUs are insanely efficient. Also from my own experiments I was able to get a 2070s down to about the power draw of a 1660ti with some 30% more performance.
Hmmm... What about unplugging the 6-pin connector? Then you will be forcing the GPU down to the 75W from the PCIe slot. I would be really curious if the card would be able to run that way...
The rx 6800 (non XT) normally rates really high for efficiency, and only pull about 215w by default. They use a really low mv by default and have the 128mb infinity cache. I think they might beat the rx 6600 in many efficiency tests with undervolting as many miners achieved great results doing.
Actually the whole motivation of this video (tweaking the rx6600 for maximum efficiency) is totally pointless without the right tools (MorePowerTool). My thoroughly undvolted (SoC/GPU/MEM) and power limited 6900XT already blows the A2000 out of the water at capped 75W in terms of efficiency. But it's a bit more expensive, so probably not the best comparison.
So to start with the RGB advertising from Be Quite, I don't like devices with RGB lighting at all except for monitors. I convert PCs that have RGB so that they don't have RGB, for example by turning off RGB in the BIOS or removing the RGB controller and throwing it in the trash. But what I can say about small graphics cards is that I prefer the low profile graphics cards to the huge blocks you have in the PC case.
I would have used a fair gpu benchmarking method, battlefield favours Radeon and GTAV favours Nvidia, Furmark is a great gpu stress test that you could use to test more fairly
I've undervolted my RX 6700 XT from 1.2V to 1.12V. It never passes over 200W (in Furmark reports 199W, in games it's closer to 150-160W). I'm in general really impressed from effectiveness of Navi cards, as it's really nice - at least compared to some terrible older AMD cards (R9 290X and R9 390X, we all remember). Really hoping, that next generation will kickass in this aspect, especially after all the RTX4xxx power consumption rumours.
I ended up not doing the needed research and ended up with my current PC with these specs. 12th gen Intel core i9 16GB DDR4 GT 1030 1TB SSD and a 180 watt power supply... I need a GPU that won't kill my PC (It needs to be as power effective as possible) but I want the best performance possible too. I was thinking of getting an RX6600 because I think they only draw 100 watts under load.
My settings on my rx 6600 is 1.075V and 2Ghz, it consumes 50W max at -20% performance, 2.08FPS/W equivalent on the GTA one. Could probably reduce a bit more voltage or whatever for better power consumption since i only bought it because my former GPU was broken and in most cases only need 10-20% of its performance.
I have the exact same rx 6600 model, powercolor hellhound, I got it for a very fair price, really happy to see its efficiency and insane amount of fps it gives, we love rdna2, nice video dawid, keep it up!
Mr Dawid, if you want to see better efficiencies, drop the clocks down. Instead of "give me as many frames as you can get" tell the card "give me 60 (or however much you want) frames but in a most efficient way". In your example, even by dropping fps (I don't just mean capping them at 100, I mean underclocking to the point where it's the highest stable result you get) to 100, you'd be able to underclock a lot, which in turn will make undervolting waaay easier (from my experiences at least, the gpu may crash at 800mV (lowest possible) at 800MHz but taking it up to 840mV makes it stable at 1000MHz etc)). In my example, I can play some games (for example grounded) at stable 45fps (I know it triggers some people that not everyone plays at 144fps, I know) with ~40-50W instead of 45fps at 80-90W using default gpu settings (capped at 45fps) or ~70-80fps (~67% more) (uncapped) at 125W (178% more). This is efficiency. Would also make a sensible video material as a follow up to this one. If I wanted to play at 60fps I'd probably get it to something like 70W at most which compared to default settings would be 55W less (44% less) for ~15fps less (~20% less).

5:56 You're doing it wrong! Don't undervolt with sliders! By undervolting with sliders you make the GPU crash by lowering the lowest power states (because the lower ones are more susceptible to crashing), but you want to undervolt the highest power state - the full performance power state. You could've used the knobs in advanced mode in WattMan or even MSI Afterburner's voltage/frequency curve! MSI Afterburner info: The voltage/frequency curve actually works and can reduces state 7 voltage (or whichever state is the highest one). IIRC I've reduced the power consumption of my RX 580 by about 1/3rd without dropping its clock speed by a significant amount. If you want, you can also reduce other power states with the voltage slider, but the slider won't reduce the highest power state voltage as much as the curve does. That's because the slider reduces all voltages at once (same as in WattMan), while the curve allows you to fine-tune each power state without dropping the lowest state below the crashing point (same as advanced mode in WattMan). On the contrary, the frequency curve only increases the highest power state's frequency (also in both programs, I think). MSI Afterburner guide: 1. Start by undervolting with the voltage slider as low as the card can take it without changing the frequencies. This decreases the voltage of all power states at once, including the lowest one. The voltage/frequency curve can't reduce the lowest one (on my GPU). This step is only important if you want to decrease idle and V-sync power usage. 2. Reduce all the frequencies with the frequency curve to allow more undervolting if you wish. The frequency slider only affects the highest power state. 3. Don't touch the frequency slider, it's not needed. When you can't bring the voltage slider down any more, reduce just the highest power state's voltage with the voltage curve. It probably has a minimum voltage, under which changing the curve won't bring the high state voltage down any more (this could be tweakable by changing the BIOS). 4. Keep reducing the highest power state frequency with the curve to allow more undervolting on the highest power state curve. 5. There you have it. You've (probably) successfully undervolted all power states, while undervolting the highest power state much more than the lower ones. Note: the sliders and the curve complement each other but don't display the sum effect in their numbers. For example, -50mV on the slider and -50mV on the curve results in -100mV, but each one still shows -50mV.
Unfortunately the AMD voltage slider is SUPER weird. It DOESN'T actually set a limit on the voltage. What it does do is encourage the card to reach higher clocks at a given voltage. So it will be more efficient, but not by much and it will use just as much power. If you REALLY want to make things more efficient, you need to use MorePowerTool and set a limit on the voltage. This will DRASTICALLY reduce the heat output and allow it to be much more performant and efficient. You can probably get away with -50mv. I was able to get away with -75mv on my 6800xt and it runs fantastic. Not sure about the 6600 tho Hopefully this provides some useful info. Sorry you made an entire video only to realize AMD's driver voltage control is basically non-existent lol
I actually set TDP slider to same wattage as RX 6500 XT on RX 580 and it gets more fps per watt than 6500 XT and then I undervolted it and it completely blows away that 6500 XT, not to mention uses way less power and doesn't roast my tights no more. But for real, this makes me question if RDNA 2 is really all that efficient. It just seems that GCN was badly sabotaged by wattage limit set to the moon and then overvolted the crap outta them. Considering how popular Vega undervolting was, it seems to span across a whole range of GCN cards. And even argument "but you can also undervolt RDNA 2" doesn't work well, since it seems that they are from factory on knife's edge when it come to voltage and maximum wattage. In BF5 RX 6600 couldn't even reach last 200 MHz of boost, despite undervolt, meanwhile, my RX 580 runs out of boost and just uses less watts at that point. I know taht this is something for HWUB to make a video about, but that made me curious. What makes this case even more interesting is that you can modify vBIOS of those GCN cards and set maximum wattage lower or tweak timings for extra perf gains too, meanwhile that's not available on RDNA 2 cards at all. You can set RX 580 to 10 watts if you want, meanwhile RX 6000 is like "-6% is best I can do".
LOL. While crypto mining was still profitable I run RX6600 XT using 63W. You need to decrees GPU Clock while maximizing memory speed. If I remember correctly I run GPU at around 1300 MHz. BTW that A2000 is also seriously underclock vs standard cards
The undervolt and power limits are not the same. If you lower your power limit, the clock speed will reduce too. However, if you undervolt it, the power will be reduced but the clock speed will remain the same. By the way, GTA 5 prefers Nvidia GPUs. That's why A2000 wins in GTA 5.
You need the most CUDA cores possible. 100 cores at 1000 MHz is much more efficient than 50 cores at 2000 MHz despite similar performance, especially since power consumption is exponential with voltage. A 3090 Ti will probably be the most efficient per Watt if it's undervolted and underclocked a massive amount. They also use better bins on the highest end parts so you should be able to undervolt more than a 3080 (lowest end G102)
Thing is, you didn't overclock the A2000. This tiny thing can easily clock to 20% gains in fps with no considerable increase in power. So unfortunately RX6600 loses this battle.
You need to set lower clock speed to allow GPU core run in more optimal part of V/F curve. This curve is not linear, at lower clocks card will gain efficiency due lower voltage. No need to decrease voltage slider, it's not fixed value. You might even need to increase slider if voltage drops too much at lower clocks. Also overclocking will increase voltage because new higher clock speed is higher on the curve. Very similar to Zen3 CPUs, highly dynamic and voltage follows clock speed. I'd use HWInfo or GPUz to monitor GPU voltage.
You're doing it wrong. At least from an nvidia perspective. Try msi afterburner. The voltage cure editor. That's the way i do it and it works very well... if you know how to do it right. I've got my rtx 3060 ti at 950 mv running at 2000 mhz, constant, under load. Not only did i reduce the voltage, not only does it run cooler, it also gives me a much higher score in time spy. 800 points boost to be exact. Just learn how to use msi afterburner.
A couple of comments on this one already, but the RX 6400 is another low power option, TDP of 53W and tested on Tom's Hardware at 53.7W. However, it's just not as fast as the A2000, so the lower power might not be enough.
Your math's is wrong dude ;) What most people are interested is (FPS/W) / COST . A2000 is too expensive to be considered for anything. But cards that deliver lots of FPS per W and are not too expensive are winners today.
MATH!!! Aluminum! lol Though ya do say against/again and been correct. We don't in Murica. Even many Canadians say it the right way. People get mad when I say (uh-gaynst) or (bee-n) Love You D! 😉😉
Idle curiosity: What if you pull the power connector from the RX6600 so it can only draw power from the PCIe connector? Maybe no life, maybe horrible instability, maybe flames! ...or maybe that will force the card in to a low power mode to prevent drawing too much from the motherboard.
I wonder how it would work if let's say 60 FPS limit was also enforced all the time... along with messing around with other sliders of course... just to see "for how cheap I can go in terms of GPU power draw to get 60 FPS in e.g. GTA V before stability goes out of the window?" :-)
the 6600 has gotten a lot better from my understanding since its release, there was some major driver changes and the new amd thing that helped all 6000 series with preformance(i forget what its called)

You should build a "green pc" that is super power efficient. Kinda like the one LTT made a couple years ago
i have got a gtx 1070 undervolted and underclocked pulling around 85w down from the stock 140w if i leave the card at stock, plus my old haswell i7 pulls around 50w during gaming. From the wall i measured 175w total power draw while running dying light 2 which i find to be pretty damn efficient for the performance of the system as it runs great at 1080p and i only lose about 7fps typically.
Green pc = no pc
@@JudeTheRUclipsPoopersubscribe yea Pascal was nuts when it came to power efficiency, even the 1080 (the launch flagship) still only needed a single 8-pin, which I still find impressive
Agreed. I'm super horny for super efficient builds. Something about optimization gets me going.
@@exaltedb it's also amazing how much you can tweak pascal cards. I mean I managed to get -200mv and dropped the core down 100mhz to 1760mhz and it's stable and running great and barely lost any performance. You definitely can't do the same thing with an ampere card without it crashing and being unstable.

@@FriENTlyFire yeah you gotta change asap
@@FriENTlyFire Yeah dude
The 2600 was a nice budget CPU at the time, but I upgraded from one to a 5600 about 2 weeks ago and it gave my RX 570 a massive boost.
Considering the 6600 is twice the performance of an RX 570, you'll see an enormous improvement by making an upgrade.
i don't think it was, the 3700X never reached 90%, the 6600 was always near 90%. Looks like it's GPU bound to me.
@@steveqi9309 You can be CPU bound by Single threaded performance or by IPC, CPU clock speeds or RAM configuration, doesn't necessarily have to be from high CPU usage, also if the GPU isn't fully utilized (97%+) and it's not the hardware it could also be poor game optimization or driver related.
I pegged my laptop 2070 Max-Q to 1185mhz and it uses 70w or less whilst gaming and in conjunction with disabling turbo boost I've been getting ±60fps gaming experience in resident evil 7 at 1440p max Ray Tracing (with interlacing)
The reason I'm doing this is to conserve power on my campervan battery.
Also note that Resident Evil 7 RE Engine is an optimization beast. That thing runs amazing in lots of configurations. Capcom really nailed it with that one
@@Chronologo Oh 100%, same with all of them to be honest! Love these games so much. Can't wait for Resi 4 remake! I figured as long as I can have a 60fps 1080p experience I'm good and I worked out total system draw is probably around 100w or thereabouts which should enable me about 4 and a half hours worth of gaming assuming the sun has gone.
Using the laptop screen I can probably save some more power and use 1080p more. Just have to see if I can change the screen for 144hz to 60hz to save more power
yep, your 2070 super max q is no less efficient than these desktop GPU-s. 3000 laptop cards are even more efficient, so this guy was wrong when he was talking about "the most efficient GPU on the market" because that's the laptop 3080 ti.
you should have limit gpu freq not the allowed power draw, i saw that on my own 6700xt ... just lock it at a lower rate
It's worth noting that NVIDIA and AMD report power usage differently through software, so it's not really 100% comparable. It's better to have a physical measurement of power draw using something like the NVIDIA PCAT instead.
as he said
Only Measures how much PC is pulling out form wall are realisable. Due different GPU drivers stress cpu in different manner.
Exactly! Many people don't realize amd is pulling more then the let on! I find it funny the real knowledgeable have all explained how it works. Yet people still want to act like ita 200watts to 250watts eveb at the high end.
@@reviewforthetube6485 Yeah, that's unrealistic, unless you undervolt.
True story...my 6600xt is usually drawing about 20% more watts at the wall using a killawatt plug. Wattman is way off
You can use the morepowertool to do much more tweaking to the 6600. Lower to power limit to whatever you want, also undervolting the memory.
This.

From my experience, using RX 6600 XT and RX 6800. You have to set the minimum frequency to 100mhz lower than max value. The frequency keeps fluctuating if the min is kept at stock value (i think it was 500mhz). Do not worry, on idle, it will not stay at the min frequency, it will downclock to very low value.
Nope: it can hurt 6600 XT's performance by around 20%. Try comparing Furmark benchmark scores
No. Best performance is somewhere in between. Idk why, but amd overclocking is just wierd. (Source: did a lot of tinkering with 69xt, from 180 watts, to 500+)
I did also spend a bit of time playing around with the min value. Sorry I should have more clearly showed it in the video. 👍
@@DawidDoesTechStuff on my 6900xt efficiency improved when not hitting power limits. Lowering max clock helps too. I ran it at 180w with significantly more than stock performance. RDNA 2 OC is like voodoo magic 🤦♂️. Let's hope rdna 3 is a bit less wierd.
@@b127_1 Haha!! It did really feel like Voodoo magic when I was playing around with it. Let’s just say the weirdness gives it character. 😅
I think you weren't getting any higher clocks when moving the slider because you were hitting power limit, if you moved the power limit slider to the right, it would let the card reach the clocks you want it to, but then again that's against the point of the video because you're increasing wattage for minimal gains probably.
Yeah, that’s kinda what I was thinking. The card just didn’t have any more performance to give with that power draw.
@@DawidDoesTechStuff There is 1 more thing you can do to squeeze the absolute limit of the card. Take out those RGB lighting on the GPU . It shares the same power budget with the entire card. Since your Nvidia A2000 doesn't have any lighting, the RX6600 should be the same too.
@@fleurdewin7958 whole 0.1W lol
@Dirk Jefferson Nah, if you give the card more power and voltage it will actually reach the clocks you set in Wattman, though the performance you gain with those overclocks compared to the extra power you're using isn't all that great, as with any overclock. The highest I had my 6600XT run at was around 2900 Mhz on the core before it got too unstable with a SPPT Softmod.
I loved the 5000 series GPUs because you could push a 5700XT to be faster than a 2080 and use 250w. Or you could basically run fanless at 60w on alot of older games
Funnily enough they talked about this on DF direct the other week and they concluded that software optimisation is the fly in the ointment with trying to quantify this sort of thing!
I agree. This kind of thing is very difficult to very accurately determine.
Did you try limiting the clock speed on the 6600 to -20? In my experience on a 5700XT, that cuts the power draw roughly in half for about 80% performance, no voltage tweaking necessary.
I did not try that. That’s an interesting suggestion. I’ll go give that a try.
@@DawidDoesTechStuff heh.. Funny it's completely the opposite answer of what I got, when I said the same thing, except it was 2100 mhz, instead of - 20%, however the same point. Don't forget to undervolt, while you underclock to get even better results 😉.
Ooo goodie! Don’t expect miracles; the 6600 isn’t pushed as hard from the factory as the 5700XT was, which means it’s closer to optimal efficiency already.
@@gismo3564 What I told both of you is correct. I did try manually lowering the core frequency while undervolting. I set the card to around 2300Mhz to try and get any voltages below 1100mv to stick, but the card still kept crashing. Although when I set the voltage back to 1100mv and continued testing, I reset the core frequency to default. (In game it kept hanging around 2400Mhzish, regardless of what I did to the core frequency slider. The driver seemed to just ignore any manual core frequency input)
So I didn’t test performance/power draw with a manually lowered core clock, I just used it to try and get a more aggressive undervolt stable which didn’t work. Haha! Hopefully this clears it up. 😂
@@DawidDoesTechStuff 🤓
In my experience, somewhere above 100fps GTAV will soon become CPU bound on a single thread, making GPU changes become much less relevant.

@@denis2381 I don't think you know what simping means.
You could set a framerate cap. It would reduce the power usage and improve frame times, which looked pretty choppy on the A2000 graph.
You can use "more power tool" to reduce the power draw further. You may be able to get down to 50ish watt or something like that.
Although the A2000 is factory undervolted, I wonder if it can be manually undervolted some more and what the results would be.
DLSS, frame capping, and some PPT lowering and underclocking can also help.
This video opens the door to another question... Could a RX 6500 XT be power-throttled to the point where it could be powered exclusively by the PCI-X slot?
If I remember correctly PCs won't boot with a GPU that are not connected to power if they normally need power cables. Would be nice though if every GPU had a 75W mode. Though it wouldn't surprise me if a 75W 3060 wouldn't perform roughly the same as the MSRP-wise more expensive A2000 as both chips are essentially GA106 and we can't have that. (75W GA107 3040 to replace the 1650 pls...)
i have a sapphire rx6600, and it's night and day compared to my 3050. with the undervolt i've put on it, it never throttles inside of a deskmeet b660, and i have to run benchmarks to even get it above 78C. it's a great card, the only thing i miss from NVIDIA is stability and custom resolutions - the 6600 has a tendency to crash when upscaling and alt-tabbing.
Crashing because you have unstable undervolting.
Lmao user issue, not nvida and amd issue. Use a stock 6600 and never had a problem.
it is what I've been saying since last year when I got myself a 6600xt. But not a single person in the comments would believe me, because no big youtuber talked about it.
the 6600xt is the best card when it comes to FPS/efficiency
your right my 6600xt was a monster at mining for that reason
Not exact,HUB talked few time about it
@@dederen1492 all those videos just appeared half a year after release. I've been commenting under a lot of videos xD
Also with amd's overclocking, your clocks will be limited by the power limit ie( if your clocks are set to 2700mhz, but your hiting a power limit, the clock wont go up until you raise the power limit) as a side note you can use a tool called morepowertool to raise the max and min on the sliders
Reminds me of the time when I was messing around with RX580 and 5700XT. Those would undervolt like crazy and ramp up the efficiency quite a bit... but it would also come with some framerate hit if I tried to maximize efficiency (which was fine, as they usually didn't affect the gameplay). Still couldn't catch up to the 1660 and 3060 I have owned though, which was trickier to undervolt but incredibly efficient from the get go.
Actually limiting the max frequency in Adrenaline gives you a way bigger reduction in power consumed than can be set with the power slider, and for just a moderate decrease in FPS, if it's efficiency you seek...
Power limit slider is useless in these cards. You need to reduce the max frequency of the card to e.g. 2200 MHz and you start to see the power usage drop. You lose 10% performance but your power consumption will drop a lot more. Also the minimum frequency should be 100-200 MHz less than the max frequency to keep the clocks more stable.
Yep, the RX 6600 is quite impressive from a performance per Watt perspective, though if you want the best RDNA2 card in that respect you should check out the RX 6800 non-XT. According to the powertests Igors Lab did the non-XT Version of the 6800 basically consumes power like a 3060ti (so around 200-210W board power stock, though with a bit of undervolting it can get even lower then that) while, depending on the game, performing like or even above a 3070ti. So in terms of FPS per Watt the RX 6800 non-XT is almost twice as efficient as any other card according to his charts.
Edit:
One tip for Over- and Underclocking AMD cards, keep the Core sliders for min and max Frequency within 100 Mhz of each other, otherwise they won't do much because by only moving the max slider you're basically just telling the card the upper boost limit but due to the min slider beeing too low it won't actually try to boost that high.
I remembered this video recently and decided to do my own testing on how to improve GPU efficiency. Only I went about it a completely different way that paid off big time!
I dialed down all the sliders in the Radeon tuning section to their minimum and then at the lowest voltage I decided to slowly increase the frequency back up until I reached as far as I could go while still being stable. Once you reach a certain point you'll have to dial the power limit back up to continue on. Just keep the voltage at minimum!
Using this method on my reference RX 6800, I was able to achieve 85% of the stock frequency! This gave an over 25% improvement to performance per watt in FurMark and as much as 60% in games!
Theoretically speaking, I imagine this margin grows even greater with the more powerful the GPU you use. This is considering how number of GPU cores and the larger the memory bus matters more than raw clock speeds. I'd love to see this tried on a 7900 XTX!
I steal windows keys from best buy display PCs
This rx6600/6600xt shud be revived as a 5nm navi 34(7500xt) without any 6pin
75w can easily be done if AMD optimise it thoroughly
A fairly efficient card, but impressively less expensive. I have a newfound respect for the little 6600 I have as a spare GPU.
One thing I've found with cards that are tricky to effectively limit the power on is that if you limit the frame rate instead, you can get satisfactory power reductions. Limiting the frame rate to the same level as the A2000 may have resulted in a closer match, though it looks like the 6600's advantage in GTA V wouldn't give enough headroom for this to make much of a difference.
I am wondering if underclocking & even more undervolting will bump the efficiency of the RX6600 at all, as AMD cards are clocked very high to be competitive, but their sweet spot frequency for efficiency could be much lower (guessing under 2000Mhz). Additionally, if the card is slightly underclocked, it might not need a high memory frequency to keep it well fed with data (memory underclock), which could in turn make its efficiency even better.
RX 6600 is bottlenecked by the power limit, so overclocking does not make any difference. If I unlock my power limit to 120% I easily gain another 10% fps. So when undervolting, instead of reducing power consumption, you're actually increasing the clock speeds. What might actually make this card more efficient is an undervolt combined with underclocking
The most efficient card on the market is the laptop 3080 ti lol. At just 90-100 watts it performs like a desktop 3060 ti.
you keep doing the same wrong thing Dawid, you need to measure the watt using hardware, especially for AMD cards.
Hi Dawid, I have been watching your LP GPU video's and I was wondering if you could help me find a more efficient Graphics card for power than the a2000. I live in an area where power is incredibly expensive, so I have never had a GPU. I have been using UHD intel graphics my entire gaming lifetime.
The a2000 is very expensive as it costs more than a 3060ti and less than the 3070. Do the math to figure out how long you would have to keep your computer on before the cheaper graphics card becomes too expensive due to power.
The quadro T1000 is expensive but uses 50 watts
A used 1050ti is cheap but uses 75 watts just like the a2000
The rx6400 is new and cheap, but without pcie gen 4, its bad
The chip from the 6600 is more efficient but the memory and other components aren't, I guess thats why you can match the 60w from the nvidia.
MSI's Mech 6600 vbios is practically identical to this one, and i think it's already undervolted as far as they're comfortable with - remember this card is supposed to be 132W not 100W. compared to my EVGA 3060, the efficiency of this thing is just absurd. the 6600 XT and 6900 XT are also incredibly efficient if tuned well.
I really like these efficiency-based videos

You should’ve tested the 6400 as well. It performs quite well (at pcie4) considering its only 40-50w
Green PCs are new gaming Metas.
Gotta slap that Energy Star logo on your PC
you can try underclock + undervolt, i think this will umprove the performance/watt.
MSI afterburner power percentage slider goes a lot lower than - 6%
Using More Power Tool (MPT) you can lower RDNA2 voltage to 650mV and clocks to around 1400Mhz, this is where there is the most efficiency in my experience. Almost double the stock FPS/Watt. You also can extend the power limits lower and higher with MPT.
You also need to test power consumption at the wall, as others have pointed out.
I'd love for this to be expanded because I've done some testing with 6800xt, 6700xt, and 6800m, all to see peak efficiency for off grid gaming.
Enjoying the escaped wolves around vancuver :)
When it comes to tuning rx 6000 gpus, it seems that setting the maximum and minimum clock at 100mhz apart (for example 2500min and 2600max) improves stability a fair bit. It lets you do a bit more in term of overclocking or undervolting before the gpu becomes unstable. The youtuber "ancient gameplays" has a pretty comprehensive video on this.
Also, it is worth noting that when it comes to power efficiency, it is highly beneficial to underclock the gpu. Every gpu that I have tested so far was clocked pretty significantly past its efficiency window. Reducing the clocks by for example 100mhz leads to a significant decrease in power consumption, while not having a proportionally negative effect on fps.
I tried this on a Sapphire 6650xt nitro+ which can draw up to 203 watts in performance mode.
I paired it with a 12400 and measured power draw at the wall, since according to Igors Lab the read outs of programms are pretty inaccurate, especially for amd.
Tldr: With undervolting and underclocking, my total system power usage went from 265 watts average to 158 watts average while loosing arount 11% performance in the heaven bench mark.
Sucks to loose performance, but good to know you can tweak cards towards efficiency pretty far with very little effort.
Would be awesome though to get a video of you using the morepower tool to reach max efficiency :D
Just lower the in game video settings and you get HUGE fps/wat gain
I'm surprised about how much life I've gotten out of my five year old GT 1030, it will not perform on low graphics at all for anything like Battlefiled or Halo Infinite Fortnight however it'll do just fine for Fallout and Elder Scrolls games.

@@seven7000_ It's a fun little card, I run mine on an old small form factor HP with an Xeon.

Was definitely worth the $70 I spent back in '17.
Undervolting AMD cards is a whole other situation that I feel like you havent really figured out. I would suggest you have a look at someone that usually playes with SFF. Perhaps Optimum Tech could help you? I would walk you through it but I'm not famous.
Otherwise, as always I enjoy your videos and appreciate that you continue to have interesting content.
Prost
For amd cards, probably ancient gameplays instead.
Perhaps they're already pushing the 6600 as much as they can on the power envelope it's at. Granted, that's not the nicest model, so it's possible it's not got a great binning to begin with.
Very interesting video! If you’re doing a follow-up, could you also overclock/undervolt the A2000 further? Also I think the 6600 XT will actually be more efficient if you can undervolt the crap out of it with morepowertool.
My 6800xt is undervolted with a 10% underclock and uses 175w playing bf 2042 at 3440x1440
I lose about 8% fps but drop 20 degrees on the gpu
My point being, underclock the gpu and it will draw less power to sustain the clocks, losing performance but maybe bringing the fps/w closer
Maybe do a video making a super efficient gaming pc? Super efficient CPU GPU combo and an appropriate screen to match?
Really enjoyed this video though !
*rtx 4060 has left the chat*
Hey how does this Nvidia 2FPS per watts compare to AMD rx6400??
I cant buy the case because im in canada😢
POV : you don't know what you're doing by randomly setting sliders to try squeezing most FPS/W -> learn how a chip work and how to und/over-volt
TLDR: your results may vary.
You should try with a much higher end card. At lower power draws the more cores (CUDA or your regional equivalent) will give you more performance per watt - which is why high end laptop GPUs are insanely efficient. Also from my own experiments I was able to get a 2070s down to about the power draw of a 1660ti with some 30% more performance.
finally a reasonable comment. pity it's so few under this video
3060ti here, 110w 8500 score in timespy, so roughly 3060 desktop scores. Impressive when compared to stock GPUs at least haha.
My 1660 only consumes 30W and I can run Most games at 100+fps 💀💀💀
the 1660 pulls 100+ watts.
Hmmm... What about unplugging the 6-pin connector? Then you will be forcing the GPU down to the 75W from the PCIe slot.
I would be really curious if the card would be able to run that way...
Many gpus will refuse to even boot without it nowadays
@@cloud8521 That is exactly why I think the experiment is worth it.
The rx 6800 (non XT) normally rates really high for efficiency, and only pull about 215w by default. They use a really low mv by default and have the 128mb infinity cache. I think they might beat the rx 6600 in many efficiency tests with undervolting as many miners achieved great results doing.
my older Polaris RX580 undervolting went from 170W to 135W, so I really can't complain, also the temps dropped a lot as well
This made me feel more confident about my RX 6600
Great content, good job!👍
Actually the whole motivation of this video (tweaking the rx6600 for maximum efficiency) is totally pointless without the right tools (MorePowerTool). My thoroughly undvolted (SoC/GPU/MEM) and power limited 6900XT already blows the A2000 out of the water at capped 75W in terms of efficiency. But it's a bit more expensive, so probably not the best comparison.
So to start with the RGB advertising from Be Quite, I don't like devices with RGB lighting at all except for monitors. I convert PCs that have RGB so that they don't have RGB, for example by turning off RGB in the BIOS or removing the RGB controller and throwing it in the trash. But what I can say about small graphics cards is that I prefer the low profile graphics cards to the huge blocks you have in the PC case.
"By clumsily tweaking a less efficient card" So essentially do what you and all PC gamers do on a regular basis?
Haha!! Exactly. 😂
I have the 6600 and I tried the exact things you tried and obtained the same results 😂
Best configuration is already the out of the box one
I would have used a fair gpu benchmarking method, battlefield favours Radeon and GTAV favours Nvidia, Furmark is a great gpu stress test that you could use to test more fairly
I've undervolted my RX 6700 XT from 1.2V to 1.12V. It never passes over 200W (in Furmark reports 199W, in games it's closer to 150-160W). I'm in general really impressed from effectiveness of Navi cards, as it's really nice - at least compared to some terrible older AMD cards (R9 290X and R9 390X, we all remember). Really hoping, that next generation will kickass in this aspect, especially after all the RTX4xxx power consumption rumours.
I ended up not doing the needed research and ended up with my current PC with these specs.
12th gen Intel core i9
16GB DDR4
GT 1030
1TB SSD
and a 180 watt power supply...
I need a GPU that won't kill my PC (It needs to be as power effective as possible) but I want the best performance possible too.
I was thinking of getting an RX6600 because I think they only draw 100 watts under load.
My settings on my rx 6600 is 1.075V and 2Ghz, it consumes 50W max at -20% performance, 2.08FPS/W equivalent on the GTA one.
Could probably reduce a bit more voltage or whatever for better power consumption since i only bought it because my former GPU was broken and in most cases only need 10-20% of its performance.
I have the exact same rx 6600 model, powercolor hellhound, I got it for a very fair price, really happy to see its efficiency and insane amount of fps it gives, we love rdna2, nice video dawid, keep it up!
Mr Dawid, if you want to see better efficiencies, drop the clocks down. Instead of "give me as many frames as you can get" tell the card "give me 60 (or however much you want) frames but in a most efficient way". In your example, even by dropping fps (I don't just mean capping them at 100, I mean underclocking to the point where it's the highest stable result you get) to 100, you'd be able to underclock a lot, which in turn will make undervolting waaay easier (from my experiences at least, the gpu may crash at 800mV (lowest possible) at 800MHz but taking it up to 840mV makes it stable at 1000MHz etc)). In my example, I can play some games (for example grounded) at stable 45fps (I know it triggers some people that not everyone plays at 144fps, I know) with ~40-50W instead of 45fps at 80-90W using default gpu settings (capped at 45fps) or ~70-80fps (~67% more) (uncapped) at 125W (178% more). This is efficiency. Would also make a sensible video material as a follow up to this one. If I wanted to play at 60fps I'd probably get it to something like 70W at most which compared to default settings would be 55W less (44% less) for ~15fps less (~20% less).

5:56 You're doing it wrong! Don't undervolt with sliders!
By undervolting with sliders you make the GPU crash by lowering the lowest power states (because the lower ones are more susceptible to crashing), but you want to undervolt the highest power state - the full performance power state. You could've used the knobs in advanced mode in WattMan or even MSI Afterburner's voltage/frequency curve!
MSI Afterburner info:
The voltage/frequency curve actually works and can reduces state 7 voltage (or whichever state is the highest one). IIRC I've reduced the power consumption of my RX 580 by about 1/3rd without dropping its clock speed by a significant amount. If you want, you can also reduce other power states with the voltage slider, but the slider won't reduce the highest power state voltage as much as the curve does. That's because the slider reduces all voltages at once (same as in WattMan), while the curve allows you to fine-tune each power state without dropping the lowest state below the crashing point (same as advanced mode in WattMan). On the contrary, the frequency curve only increases the highest power state's frequency (also in both programs, I think).
MSI Afterburner guide:
1. Start by undervolting with the voltage slider as low as the card can take it without changing the frequencies. This decreases the voltage of all power states at once, including the lowest one. The voltage/frequency curve can't reduce the lowest one (on my GPU). This step is only important if you want to decrease idle and V-sync power usage.
2. Reduce all the frequencies with the frequency curve to allow more undervolting if you wish. The frequency slider only affects the highest power state.
3. Don't touch the frequency slider, it's not needed. When you can't bring the voltage slider down any more, reduce just the highest power state's voltage with the voltage curve. It probably has a minimum voltage, under which changing the curve won't bring the high state voltage down any more (this could be tweakable by changing the BIOS).
4. Keep reducing the highest power state frequency with the curve to allow more undervolting on the highest power state curve.
5. There you have it. You've (probably) successfully undervolted all power states, while undervolting the highest power state much more than the lower ones.
Note: the sliders and the curve complement each other but don't display the sum effect in their numbers. For example, -50mV on the slider and -50mV on the curve results in -100mV, but each one still shows -50mV.
Unfortunately the AMD voltage slider is SUPER weird. It DOESN'T actually set a limit on the voltage. What it does do is encourage the card to reach higher clocks at a given voltage. So it will be more efficient, but not by much and it will use just as much power. If you REALLY want to make things more efficient, you need to use MorePowerTool and set a limit on the voltage. This will DRASTICALLY reduce the heat output and allow it to be much more performant and efficient. You can probably get away with -50mv. I was able to get away with -75mv on my 6800xt and it runs fantastic. Not sure about the 6600 tho
Hopefully this provides some useful info. Sorry you made an entire video only to realize AMD's driver voltage control is basically non-existent lol
I actually set TDP slider to same wattage as RX 6500 XT on RX 580 and it gets more fps per watt than 6500 XT and then I undervolted it and it completely blows away that 6500 XT, not to mention uses way less power and doesn't roast my tights no more. But for real, this makes me question if RDNA 2 is really all that efficient. It just seems that GCN was badly sabotaged by wattage limit set to the moon and then overvolted the crap outta them. Considering how popular Vega undervolting was, it seems to span across a whole range of GCN cards. And even argument "but you can also undervolt RDNA 2" doesn't work well, since it seems that they are from factory on knife's edge when it come to voltage and maximum wattage. In BF5 RX 6600 couldn't even reach last 200 MHz of boost, despite undervolt, meanwhile, my RX 580 runs out of boost and just uses less watts at that point. I know taht this is something for HWUB to make a video about, but that made me curious. What makes this case even more interesting is that you can modify vBIOS of those GCN cards and set maximum wattage lower or tweak timings for extra perf gains too, meanwhile that's not available on RDNA 2 cards at all. You can set RX 580 to 10 watts if you want, meanwhile RX 6000 is like "-6% is best I can do".
LOL. While crypto mining was still profitable I run RX6600 XT using 63W. You need to decrees GPU Clock while maximizing memory speed. If I remember correctly I run GPU at around 1300 MHz. BTW that A2000 is also seriously underclock vs standard cards
I love watching pc power efficiency videos
The undervolt and power limits are not the same. If you lower your power limit, the clock speed will reduce too. However, if you undervolt it, the power will be reduced but the clock speed will remain the same. By the way, GTA 5 prefers Nvidia GPUs. That's why A2000 wins in GTA 5.
You need the most CUDA cores possible. 100 cores at 1000 MHz is much more efficient than 50 cores at 2000 MHz despite similar performance, especially since power consumption is exponential with voltage. A 3090 Ti will probably be the most efficient per Watt if it's undervolted and underclocked a massive amount. They also use better bins on the highest end parts so you should be able to undervolt more than a 3080 (lowest end G102)
Thing is, you didn't overclock the A2000. This tiny thing can easily clock to 20% gains in fps with no considerable increase in power. So unfortunately RX6600 loses this battle.
You need to set lower clock speed to allow GPU core run in more optimal part of V/F curve. This curve is not linear, at lower clocks card will gain efficiency due lower voltage. No need to decrease voltage slider, it's not fixed value. You might even need to increase slider if voltage drops too much at lower clocks. Also overclocking will increase voltage because new higher clock speed is higher on the curve. Very similar to Zen3 CPUs, highly dynamic and voltage follows clock speed. I'd use HWInfo or GPUz to monitor GPU voltage.
You're doing it wrong. At least from an nvidia perspective. Try msi afterburner. The voltage cure editor. That's the way i do it and it works very well... if you know how to do it right. I've got my rtx 3060 ti at 950 mv running at 2000 mhz, constant, under load. Not only did i reduce the voltage, not only does it run cooler, it also gives me a much higher score in time spy. 800 points boost to be exact. Just learn how to use msi afterburner.
A couple of comments on this one already, but the RX 6400 is another low power option, TDP of 53W and tested on Tom's Hardware at 53.7W. However, it's just not as fast as the A2000, so the lower power might not be enough.
Your math's is wrong dude ;) What most people are interested is (FPS/W) / COST . A2000 is too expensive to be considered for anything. But cards that deliver lots of FPS per W and are not too expensive are winners today.
MATH!!! Aluminum! lol
Though ya do say against/again and been correct. We don't in Murica. Even many Canadians say it the right way. People get mad when I say (uh-gaynst) or (bee-n)
Love You D! 😉😉
Idle curiosity:
What if you pull the power connector from the RX6600 so it can only draw power from the PCIe connector?
Maybe no life, maybe horrible instability, maybe flames!
...or maybe that will force the card in to a low power mode to prevent drawing too much from the motherboard.
I wonder how it would work if let's say 60 FPS limit was also enforced all the time... along with messing around with other sliders of course... just to see "for how cheap I can go in terms of GPU power draw to get 60 FPS in e.g. GTA V before stability goes out of the window?" :-)
the 6600 has gotten a lot better from my understanding since its release, there was some major driver changes and the new amd thing that helped all 6000 series with preformance(i forget what its called)
REQUEST!!! Please use God of war/Halo infinite games for testing graphics card and or pc specs that you guys get in the next video...thank you and love your videos ever since I subscribed 👍👍
