7950X3D vs 7800X3D - Is AMD's 16 Core a SCAM?
HTML-код
- Опубликовано: 26 июл 2024
- After taking a look at two separate channels, I decided to run some tests with an Ryzen 9 7950X3D with half its cores cut (so basically a Ryzen 7 7800X3D Simulated), and then decided to run some background applications on the spare cores whilst running games, to see if you are getting a Ryzen 7 7800X3D that can turn into a Ryzen 9 7950X, or if you are getting what AMD says you are getting.

Sorry for slow content, had reactions to allergies to the point where my chin was swelling up lol... Anyway getting much better now. Hope you guys enjoyed this one!
Yeah, Frame Chasers is kind of a bell end, but he is right about the chip. I don't trust the guy, but I do keep an eye on him. Better than Linus gets, cause I can't stand him at all!
Hope you're feeling better, Sir. o7
I’m glad you called out frame chasers. I can’t stand the guy. He’s an elitist and a jerk. He charges 500$ for just a consult for a tune for warzone. If you watch his live streams he’s toxic af. His discords even more toxic. Hes had tons of people complain about him and he just blocks them. He’s quite rude to people who question anything he says, he says he doesn’t watch any other content creators stuff and doesn’t listen to anyone’s testing. He thinks
He is a god and thinks All his oc nunbers are the best. He won’t tell anyone his voltage and tries to claim everyone’s after his secrets and they’re stealing his secrets. He’s got some big conspiracy theory that everyone’s out to steal his lucky charms.
Never use framechaser as a source. What nonsense he puts out.
@@kaisersolo76 Yeah, it's lie using WCCFTech or Wikipedia as a source! LOL! That said, I still keep an eye one him. He at least has a point once in a while, unlike Linus!
Had the same reaction about 15 days ago when the weather was nice and went on to a small forest (closely urban) and sat on a bench for about an hour.. someone told me that these was to some dust that is produced through pines or caterpillars (those that form large chains and get up on logs of trees)
Anyway.. the one thing is to never touch th9se reg8ons on the skin though it rushes you to itch, and apply some soothing cream..and wash it only with mild soap and not rub at all.
hope yoy recover fast
I'm mega power user I need 7950X3D, I even created my own custom SLI profiles for games that didn't support SLI back in the day and I got SLI working for unsupported game. 7950X3D is tweaker's dream CPU! You can tinker and tune so much it's just a treat. I'm not some console player that wants to start PC and game. I want to tinker, set things, tune, more tuning.
I wonder what FPS these can do in DOS Quake at 320x200 🙂
🤯
damn Phil, you are quick, anyway it will be high but it seems consistency is a big head scratcher
when the whole game fits in your cpu's cache
You are capped @ 1000fps regardless because of nvidias driver implementation no matter what games.
@@JoeMama-yl1ow PCI 3dfx Voodoo to the rescue 🙂
This is the best take on this “situation” out of all the channels. It takes into account both sides and boils it down well. Thank you for doing that, especially that trash DDR5 is better and gear mess the other channels were incorrectly configuring. Keep it up.
One thing to keep in mind is the PPT limit of the cpu if you're heavily taxing the non vcache portion of the cpu, your vcached core clocks are likely going to suffer to stay within that limit.
The 7950x3d is definitely an enthusiast chip, it's not just a gaming chip.... if you are just a gamer get the 7800
If your just a gamer get the 12100 or 13500
@CaptCapitalist hell, pretty much any 6+ core processor will run most games fine... I did a 8 core fx 8120 and it handles most titles with a fatboy 590
I'm glad to covered this. It's been bugging me since they revealed the architecture of the thing.
Brian, I don't know if the footage in the video is direct from benchmark captures but when setting the core affinity to Corona Benchmark, I think you set it to 13 cores (19 to 31) instead of 12. I have no idea if it makes an appreciable difference in the results you were trying to obtain but I figured I should point that out. Great content, as always. Cheers!
Your content is always good for me as I seem to learn something new that I can use.
Maybe we need to redefine what is a pc enthusiasts….
One moment it’s someone who is coming up with custom memory timings and fan curves and overclocking the cpu and gpu.
And another moment it’s to hard to follow directions to assign cores.
It’s always something in this hobby.
Either way have as much fun as you can ❤
Bro if u r into tuning n ocing u wud get 13900k anyway . U tune once n u r good. U dont have to do it for every application like this cpu n 13900k tuned beats this in gaming n productivity. That’s y it’s called a scam.
If u jus want gaming 7800x3d wud be easily better
@@anuzahyder7185 Someone who can't speak English shouldn't be lecturing anyone on the definition of the term scam.
@@snotspat I can translate the 13900ks is better if you wanna be in a bios screen overclocking. Mostly due to better 1% lows. Your getting scammed because of amd misleading a lot of customers some people thinking the 7950x3d boost higher than the 7800x3d in gaming or that both ccds were v cache and my favorite that the scheduling just works automatically which for many programs people are talking about lassoing their cpu.
@@majicalpandatech yeah it is telling that the 7800x3d hasn't been released yet.
Thanks for your take on this. I was stoked about the CPU until the details came out. I'm happy with my 5900x but I was able to snag an RTX 4090 and I am going to want to upgrade my cpu again in a few years. I hope there are some ways newer processors will be able to report certain things to the operating system about their topology and how to handle thread scheduling more transparently though today that isn't the case. Applications will also need to catch up so it's like the chicken and the egg. We know the chiplets and "tiles" are coming for specific tasks and acceleration but today you can have a very powerful CPU and an OS that isn't really able to fully leverage it because of lack of awareness which isn't ideal.
I too have a 5900x and 4090. Assuming you play at 4K like me, there really isn't a CPU worth upgrading for at the moment, these 3D chips included. That will change with the 5090 and next generation CPUs however.
@@HeloisGevit I lol'd
I got 5900x and a 4090.
Now I don’t know if it’s worth upgrading to AM5 ugh
7950X3D 16 with 8x3D
7900X3D 6x12 with 6x3D
Imagine the rage when the 7800X3D comes out and they went 4x4 instead of using 5800 template.
Lol that would be hilarious
The CCD in zen 4 is 8 cores each so that would not happen at all.
The 3900X 5900X, and finally 7900x are 6 core CCD's. No surprise it has ALWAYS been that way! If you bought one thinking it was not than that is the consumers fault for spending money and not understanding what it is they are buying!
7950X3D = 8 core CCD0(X3D) & 8 core CCD1(non X3D)
7900X3D = 8 core CCD0(X3D) & 4 core CCD1(non X3D)
7800X3D = 8 core CCD0(X3D)
7950X3D = 8MB cache per core.
7900X3D = 10MB cache per core.
7800X3D = 12MB cache per core.
RUclipsrs who have disabled CCD1 from 7950X3D doesn't have accurate 7800X3D benchmarks.
For example:
7950X3D CCD0 (50W) - CCD1(50W) - iGPU (20W) = 120W total.
If they disable CCD1 (non X3D) it will only run 70W (CCD0 at 50W) and iGPU(20W).
CCD0 won't get anymore then 50W that voltage/power is limited/locked it's for all CCD's.
7800X3D will have additional 50W more power available and this with 12MB cache per core.
Will increase even more fps and higher jump in gaming performance then 7900X3D which has 2MB more cache.
But can't deliver that additional power to CCD0 as it's lock due to dual CCD's limit which is 50W, except the 7800X3D.
This is why it doesn't need higher clocks it has more cache per core and double the power draw of dual CCD on a single CCD.
My analysis and expectation of 7800X3D is going to aim for gaming performance better then 13900KS that's right KS!
7900X3D/7950X3D will get updates overtime and get slowly better performance but the 7800X3D will BLAST OUT 7950X3D/KS.
They'll all perform similarly. Nothing special about X3D this time at all. Incredibly disappointing launch and results. Not even 4K numbers change where as 5800X3D did over 5800X. These CPU were just made for competition with Intel or to beat them ever so slightly.
Thought I would throw a few dollars your way bro. Thanks for being a reasonable dude and keeping your channel positive man. There's enough negativity online, you're a pro at being professional and decent about everything you cover. Very solid example of being an adult online, we need more of that out here for sure bro. Keep it up man! Much love from the States (Seattle area).
100% agree.

The point of the 7950x3d is to be “as good” as a 7800x3d in gaming AND “as good” as a 7950x in multi core workloads.
It’s meant to be best of both worlds, I’ve got a 7950x3d for gaming but I also like to work in blender and do 3d modelling for 3d print sculpts. If I got the 7800x3d it would struggle with my blender workload,
If your main focus is to primarily play games, than for sure you should wait for the 7800XD3. And even if you want to get the 7950X3D you should wait until the 7800X3D comes out because they will soon start to heavily reduce the price of the 7950X3D because its sales will get even worse once the 7800X3D comes out.
Theres no reason to reduce price wheb the cpu is sold out everywhere 🤷♂️
There is no point getting a 7950x3d. The 7950x is $200 (!) cheaper here, for a loss of 6% in games. Then its like 600 fps or 550fps.. which no one will notice anyway.
what sales do you mean? its sold out since day 1 in germany. where do you live?
the point in buying a 7950X3D is the multicore performance, duh
if you want BOTH top tier multicore AND gaming
no other processor does BOTH
Intel is inefficient in multicore, 7950X is shit in gaming, 7800X3D is shit in multicore
@@AndrewTSq really depends on the games you play certain games the v cache is a game changer
We should just wait until the real 7800x3d comes out and test then, because there will be a difference in the Vd cache so performance will differ. Great vid as alway's Bryan :D
still waiting for the frame chasers vs hub punch on.
Would like to see Gaming and doing other tasks like streaming and production work etc... at the same time to see how the performance differs with more than 1 more primary workload
"I can run tests at 1080p with an RTX 4090, I know it's unrealistic..."
Me watching this video on a 1080p monitor plugged into an RTX 4090 😐
a content creator talking about other content creator? My mind just blowed up. Great vid my friend keep up the good work. I'll stick to my 5800x3d you recommend some time ago and worked like a charm.
Nice video.
Did you also simulate the lower CPU boost of the 7800X3D?
In what way, the listed 7950x3d higher clock boost is only on the second CCD that doesn't have the extra 64 MB of cache (disabling it turns the 7950x3D into a 78000x3d)
Installing the AMD chipset driver and making sure Xbox game bar is enabled it core parks the second CCD on the 7900x3d/50 (as long as Xbox game bar detects the running game)
My concern with the 7800x3d is that it looks like AMD is purposely hamstringing it's clock speed which reeks of a scam to make sure it doesn't get the same performance of the 7950x3d in gaming. Not to mention it's probably going to fall on it's face if you try streaming while playing.
The 7950x3d is for those rare people who's favorite game is the bios screen.
the benchmark of the 7800X 3D recently released from amd themselves shows that on the worst case scenario the 7800X3D is at 124% speed down from 127% for the 7950X 3D. Clearly the 7800X 3D is the better choice, other games around 120 % are withing margin of error they perform the same. for 250$ less
@@Tigerhearty Oh I fully expect it to make the 7950x3d to look stupid, but it's still kinda shady to limit it's clocks when it's the exact same CCD, especially at $450. Just like the BS Intel pulls with their non-k parts that we all know can clock FAR higher if they were unlocked. Imagine a fully unlocked 13100kf. It would be the budget gaming king even more than it already is.
@@zodwraith5745 They could have made the 7800X3D 5.7ghz and it would have just crushed the 7950X for being able to sustain single core speed to very close to 5.6 / 5.7 when the 7950X3D with it's poor ccd x2 delay is having trouble keeping at 5.2 ghz under gaming even with half the ccd and cores disabled for sure but it wouldn't have made financial sense as the newer iterations of the cpu would have looked "bad" in performance comparison to the 7800X 3D and barely anyone would feel any need to upgrade. Those are all long planned in advance progression margin, not "customer friendly" decisions anymore. it is obvious they can clock a lower count, less intensive heat dissipation cpu higher then a more gigantic 2 times the size and 1.3X the 3D stacks on higher skus, they are becoming as bad as intel when they have the means to do much better then that and easily
@@Tigerhearty I'd argue they've easily been as bad as Intel for years, if not worse. What happened to Threadripper pricing the second AMD had no competition? For a decade that Intel dominated AMD we didn't see ever increasing prices and $6000 HEDT chips. I paid the same for an i7 960 as a 4790k, 7700k, 8700k and 10700k. With inflation that's a price _reduction._
Only recently has the i7 crept over $400 while the AMD equivalent launched at freaking $550 on an even more expensive platform.
Nah, AMD is worse than Intel these days. AMD prices used to keep Intel honest, now days Intel prices keep AMD honest.
Bryan EZ 🍿👑
Pretty sure no one really wants to mess with affinities when I just wanna play games well, on any CPU.
Anyone in the business could see this coming from a mile away. There's a very good reason that the 7800X3D is so heavily delayed, they tried to sell as many 79**X3Ds as possible before people caught on.
I'm sure the 7800X3D will be a great CPU for mainly gaming, but this business practice is so anti-consumer it reeks.
It's been delayed a month that's hardly heavily delayed 😂
@@LawrenceTimme It’s the only 3D chip that makes sense and matters to gamers. AMD is making scummy anti consumer moves.
Dumb comment. This is like saying 13900k is pointless cos 13600k will give you similar fps. No one buys 16cores cpu just for gaming, dummy
true, considering the amount of time you have to wait, if people value their time, they just buy any CPU and gaming several months already instead of waiting.
@@ZackSNetwork didums, you are so impatient you cant even wait a month. Lol. This is why gamers always get shafted. It's not cos the companies are greedy, it's because the gamers are greedy. They want it all now like a child. Pathetic. Daddy I want it nooooooowwwwwww. Reeeeeeeeeeee
Seeing framechasers get a shoutout here brings a smile to my face
Great content! I love a reasonable perspective on this type of topic. There’s way too many channels and people that are amd fanboys thinking amd can’t do wrong. This is just being critical to see the full perspective
7800 is a better buy for current games, but the 7950 has a higher max clock (5.7 vs 5.0 ghz) and more cores for the future and background stuff.
Good thing for Frame Chaser’s Chanel and being able to go against the grain. Once again!
the fact that people don't understand how to utilize a cpu to it's maximum potential, doesn't make a product a scam, people just dumb
The 2 separate cache chunks slowing down access to the caches seems unfortunate to me.
Great nonpartisan logical breakdown. Exactly why I'm subbed to this channel. Bravo.
If you're just a gamer get the 7800x3d if you do editing and productivity and gaming get the 7950x3d
I would just save the money and get the 7950x or the 13700k.
If you want the best of both worlds the i9 13900k is the best CPU still.
@@ZackSNetwork hopefully amd finds a solution or does the same thing intel is doing with big/little cores
@@ZackSNetworkif want best of both world, you get both CPU.
@@ZackSNetworkis the i9 13900 really better than both?
Techpowerup did a similar investigation and found that the 7950X3D with one CCD disabled performed as good, and sometimes a bit better than the full 7950X3D in gaming.
Brian seems a bit confused about what his message is in this video. That early adopters of the hybrid CPU that is the 7950X3D have to do a bit of extra work to get them to run properly has nothing to do with the question as to whether they're a scam or not. They're not. Frame Chasers clearly doesn't understand how core parking works and he's flat out wrong when he says that only one chiplet works when you're gaming. Gordon's not the only one to have proven him wrong, Level1Tech did a really good explanation not only of how it works but why the approach AMD and Microsoft have taken is the only sensible option.
So you also should run the clock speed at the 7800x3d speed for absolute comparison
7950x3d has more cache. it's a jank simulation
I thought this too but it’s hard to say if there will be a difference. AMD is advertising that the 7800X3D will boost up to 5GHz which is what I am seeing on the V-Cache CCD on my 7950X3D. The non-V-Cache CCD will boost higher but I never catch any core boosting all the way to the advertised 5.7GHz.
Basically, we won’t know if these 7800X3D simulations are accurate until we reviews are out. I just hope that these simulations aren’t going to end up being misleading.
@@kBitre the cache resides on each core complex die. So by disabling the second ccd completely you lose all access to that l2+l3 cache. Its not using a central pool of cache that both ccds draw from they are separate. Thus disabling the ccd will make it have equal cache to the 7800x3d
@@rRefuseToSelfCensor I see. ty
@@rRefuseToSelfCensor - Thus disabling the ccd will make it have equal cache to the 7800x3d...slightly incorrect. The 7950X3D has 16 MB l2 cache, while the 7800X3D only has 8 MB. The 7950X3D also has more L3 cache, 128 MB compared to 96 MB on the 7800X3D.. Combine these with the higher boost clock speeds of the 7950X3D, I think we can safely say that the 7800X3D is not going to perform as well. How much of a difference there is, remains to be seen.
Hello Brian! Greetings to Nippon :) Quite Interesting tests and numbers, didn't expect such Low numbers on 0.1% lows like in example, Horizon Zero Dawn, to be a thing! .. like 10 fps? Something is going there..
Also nice to see there is a difference between Fullscreen and Borderless..
R.Nice keep it up!
People are just being dumb. When Wendell from L1techs says it's fine it's fine
honest video luv always the content very straight forward, good job.
7950X3D is for someone who is both a gamer and a content creator/productivity power user. If gaming is your main and only use case, as Bryan says, wait for 7800x3d or grab discounted cpus like 7700X/7600X/5800X3D/13600K.
7600x no cause 13600k is better option. 7700x idk, id still say just get 13600k... but yeah 7800x3d will be the best gaming money can buy. 13600k is the best price to performance gaming cpu.
If u want both get 13900k. Y go through the hassle of 7950x3d
@@anuzahyder7185 Eeah exactly. If just gaming get 7800X3D or if on budget get 13600K... If you want to do both game and high thread count workloads, get 13900K. 7950X3D is pointless due to how poorly AMD executed it.
If I was the 'power user' I would want the best performance for that, and the normal 7950x is best for that.
@@teemuvesala9575 Nah it's not quite as simple as that anymore in this weird transitioning phase where the customer is spoiled with choices.
If you're on budget, you're not even going to have the budget for a 13600K build. You should be looking at a 5600 or a 13500 instead.
13600k is good on the charts, but in practicality unless you plan to use it for some content creation / video encoding or VM virtualisation. You're often better served just getting a 5800X3D (similar price region) especially if you're only gaming.
For those who are lucky enough to be near a microcenter, an AM5 build is outright better value because bundles. Intel sucks in platform longevity and 13th gen is EOL. In a few years time that forward-planning will pay off.
It seems like it could be a great value for someone who wants to game and stream from one PC.
Great video, when thinking about dual CCD's and 3D V-Cache dilemma, I believe AMD took this path because they had too many regular Zen4 dies sitting in limbo.
irc the reason as per amd was that the cross ccd latency offset the performance gain by having cache on both sides.
The unfortunate fact is that the average PC users skill levels are progressively getting lower as time progresses.
This is inline with the dumbing down of society in general.
Which is great news for the marketing people who exploit this truism.
As people slowly lose the ability to think for themselves the markets will happily exploit them.
The 7950x3d is a clever piece of technology . but not a pure gaming chip.
But 7800x3d has less 3d v cache? How i understand it is 7950x3d with the same core count as 7800x3d, but that wouldn't change the cache size of the 7950x3d right? so the 79503d will still be better.
did you lower the clocks when simulating the 7800x3d toathx the specs?
Frame chasers is blunt but we need guys like that! Tell the truth. No fear!
Is the power consumption of the 7950x3d lower when you disable half the cores?
I don’t know if I’d call it a scam but like you said janky sounds more like it. In my opinion Gordon actually proved more so that it’s a “scam” when he tried to say it wasn’t. When he ran Cinebench on 4 threads while gaming it ran on the 3D CCD. Shouldn’t it have assigned that to the non 3D CCD, for better Cinebench score with the faster CCD and only had game on the 3D CCD for best gaming performance.
Great video and reflection of the 7950x3D! You are one of the most down to earth tech-channel on RUclips! :) No 7950x3D isn't a scam, not anywhere near. It has it purpose. Not any average gamer will buy that CPU. But I could, I have a high demand for many threads and stuff.
Personally I'm sitting on a 5950x. I think I prefered to upgraded to 7950x without 3D. But I'm doing gaming and much more workloads. It's enough for me. But for now, I'm not upgrading to any CPU.
I am sure that, If there was no 7950X in the first place and AMD launched 7950X3D alone, no one would ever have had a complaint about 7950X3D ! It is power efficient and cool and gives a very high frame rate with high end GPU and great productivity results too. And Disabling and enabling CCDs as needed is not a big task in AMD systems. 🤔 it is definitely the current fastest gaming CPU and is not a scam. But waiting for a 7800X3D is a good thing for more budget oriented gamers.
Yep. 7950x3d is nothing but a gimmick.
It’s a gimmick. 13900k does both but better. If u have to rely on applications n windows to work properly then y not jus tune 13900k one time n u r done. Does better in games n productivity
@@anuzahyder7185 13900k does not do both better at all. It takes more than x2 the power to still lose in fps and win by a few % in productivity. I can’t understand why people don’t understand the 7950x3d. It’s for the person who wants the best gaming while also wanting amazing productivity. Calling it a scam or gimmick is simple minded. People need to read more or watch someone like Level1Techs who actually understands this.
@@cszthompson i cant say its a scam but comparing the price with the performance u feel like its a scam. about 150$ more for just about 2% fps on games that's what called a scam. The only positive side is power consumption is about half in 7950x3d.
@@anuzahyder7185 no, the 13900k loses in both gaming and productivity while using twice the power. Intel fanboys are on copium lmao.
Did you control for the 7800X3D's lower clocks in your testing?
Are the clocks for the 7800X3D actually lower than the V-Cache die on the 7950X3D? The high clock specs for the 7950X3D only apply to the non-3D CCD so they don't really apply in games running on the 3D cache CCD.

Thanks for the review. I'll skip this gen & keep my 5950X until all issues are solved.
The issues are already solved ,, 13600k is CHAMPION
I would be interested in seeing these same tests but using an AMD GPU like the RX 6900xt/6950xt with and without smart access memory enabled. On my old AM4 5800X3D RX 6800xt and new AM5 7600x RX 6800xt systems i saw small improvements in FPS when SAM was enabled and the games seem to be smoother and abit more responsive as least subjectively. At the moment i think i wasted money on building a new AM5 system as it seems i would have been better just upgrading my GPU. Thanks for the video, take care, God bless one and all.
Thing is there wasn’t a better cpu for gaming on the am4 platform than what you already had. I almost built my pc with that cpu but as it was already the best it could be, I built it on am5, with the same cpu as you. I am now looking to upgrade to a x3d cpu. Gonna either do the 7800x3d or 7900x3d since they are very close in price.
@@MrExdous69 I went for the 7800X3D because it uses a single core complex, that leads to faster cache-to-cache transfers than the 7900X3D. Also the 7900X3D and 7950X3D required additional setup steps for windows at the time i built my system due to the duel core complex not being fully supported by BIOS, no idea if that is still a thing, but i would suggest checking if your chosen motherboard is compatabile. Also at the time the 7900X3D/7950X3D was very picky about what memory it worked best with, i assume this has changed with a wider range and updated designs since i built mine, but again something i would check. Take care, God bless one and all
@@wolfman011000 yeah after watching this I watched the gamersnexus video on the 7800x3d which pretty much totally negated the 7900x3d

Like that you covered that Frame Chaser guy, TechTubers has a Shock Jock sub-section now...
If you force the game to run on the 3d cashe'd 8 cores, and background tasks/windows running on the other 8 cores, does it perform better? - Does windows 11's different task scheduler change things?
You need Linux for that… Not sure if Windows can do that… Most likely not
Am impressed with the theoretical fps for Hogwart's Legacy. Curious how the 7800X3D fares, should be a solid contender.
Impressed with "Theoretical " wow ,, do you want to buy a used car from me? Theoritically it is a GREAT CAR
Its not unrealistic. Either in BIOS or using Process Lasso to force games to play on only the X3D cores will get gaming performance from the 7950X3D that nearly matches the 7800X3D. Using Process Lasso does not require you to park the cores and they will automatically be used for productivity tasks. Also, just today they dropped the price on the 7900X3D to LESS than that of thge 7800X3D.
Nobody buying a 7950x3d or needing its power is considered an average PC user. It's such a weird point to make.
In my country "simulated" 7800x3d has "simulated" price at the almost exact point as 13900k. Which one you'd recommend in this case?
1:32 you said it, it is unrealistic. At high resolution performance is GPU bound, at lower resolution the frame rates are insanely high to really matter to the average user. Most experts have a tough time agreeing on an exact number, but the conclusion is that most humans can see at a rate of 30 to 60 frames per second . We are comparing CPU performance based on unrealistic use cases. I am at the other end of the spectrum, I am a causal gamer I use UWQHD + (3840 x 1600 @ 60 Hz) I am happy with a Ryzen 7900 @60W TDP. When I have more performance than I really need then power consumption and heat becomes the decisive factor.
The 7950x3d seems to be the one for testers and designers, im assuming the additonal cores will help with backround processing?, had my eyes on the 7800 the whole time, but was curious about the 7950, so yea streamers too, thats what i thought.
can i just buy a 7950x3d and turn 50% off to make it a 7800x3d? then turn the other half back on in bias so run editing task/? so one cpu and be both 7950x3d and it can be a 7800x3d for gaming or wil the 7800x3d do better than half on the 7950x3d?
This processor is for a professional who also wants top gaming performance and efficiency. The type of person who won’t mind setting core affinity in apps. Pure gamers should get 7800x3d when it comes out
13900k says hi
@@anuzahyder7185
13900k is great but certainly not efficient
Hi, can you compare 7950x3d vs 7950x eco mode? Also, can you compare idle power between both the cpus (using same system expect the cpus)
I have seen a couple sites do the "simulated 7800x3D" comparison by shutting off the 8 cores that do not access the V cache. They always show that, in games, the simulated chip holds its own or beats the 7950x3D. However, I wonder if the simulated chip is being underclocked like the 7800x3D will be in comparison with the 7950x3D when these benchmarks are run? After all, the 7950x3d cores boost to 5.7GHZ whereas the 7800x3D only boost to 5.0GHZ. I know the cores for this series of x3d chips are unlocked but we do not know whether the 7800x3D will be able to boost to 5.7 so, IMO, we also do not know whether the simulated chip is a valid comparison. Enlighten me. To be clear, I have been recommending that the gamers in my family wait for the 7800x3D because I feel that it will be a much better "bang for the buck" even if it falls slightly behind the 13900K and the 7950x3D in gaming.
The 5.7GHz is only reached when it's running a few cores, probably fewer than the non X3D because of the lower TDP. This is from the Steven Walton (Techspot/Hardware Unboxed)
"The V-Cache enabled CCD1 typically clocks at between 4750 and 4800 MHz, whereas CCD2, with the regular 32MB L3 cache, clocked its cores at 4900 MHz."
It's plausible that the 7800x3D, that has the same 120W TDP, will run at the same ~ 4750MHz under load.
The reason the 7950x3d says it boost 5.7ghz is because the one without the vcache can boost that high. The one with the vcache boost a lot lower, similar to what the 7800x3d boost to.
@techyescity Brian, I'll be saving up for a 7800X3D build which will be paired with the 7900XTX, currently on 3900X paired with a 1080ti...I game at 1440p 21:9, will I get a good performance upgrade coming from the R9 3900X to a 7800X3d?
@RAM_845 absolutely it would intense upgrade
Is the CPU BETTAAA ? .... :) this is what i read if i watch your channel. Keep up that good work :)
It worth to wait that’s what I’m been doing I’m just gonna wait for the 7800x3d to come out in April then star on my new pc build I’ve been the the first gen ryzen for a long a time I’ve been holding off for a while now I enjoy your channel you always on point
Did you account for the speed difference? 7800X3D is supposed to be slower.
😅 your kinda right the chiplet that’s faster is non 3d so yeah… it’s gonna be the same
Well based on the specs
7950X3D is 8+8 cores with 128MB L3 Cache divided by 8MB per core.
7900X3D is 6+6 cores with 128MB L3 Cache divided by 10.67MB per core.
7800X3D is 8+0 cores with 96MB L3 divided by 12MB per core.
Looking forward to see if a 7850X3D with hypothetical 8+4 cores with 96MB L3 Cache divided by 8MB per core.
Interesting analysis. Thanks for your hard work. Personally, I think this CPU is basically a slightly nerfed 16 core 7950x and a slightly nerfed 7800X3D. AMD promised a best of both worlds, but what we get is a slightly nerfed best of both worlds. I think I'll stick to the 7800X3D if possible, but for people that can harness the power of a 16core chip, I guess it's a great compromise. I don't think AMD is out to milk people for their money, if I were AMD I wouldn't launch th e7800X3D first either because if I launch it first and send the cpus by air, then I would end up increasing the base price of the cpu to cover the shipping expenses. It makes a load more sense to send the highest margin parts via AIR and launch them first to target the niche market. If you're getting a 7950X3D, you'd better be making money with it.
The 7950x3d is a really useful CPU for game developers. You sometimes want all core performance for blender work, but sometimes want VCache for low latency game captures. I think having to switch between the two is clunky, but the versatility is real for them. The 6 week delay for the 7800x3d is mainly logistics. Because the 7800x3d is a lower margin part, and 6 weeks is the shipping time by boat instead of air shipping that they did for the other parts
Nah AMD’s 3D v cache is far to situational. Game developers want consistency in performance.
@@ZackSNetwork Are you and I.T or developer?
@@ZackSNetwork residential Intel fanboi spotted
@@ZackSNetwork Funny comment because it's in game devs hands to optimize their code to certain cache sizes. In perfect world very large caches wouldn't do much but at least game performance would consistent. However often it's not worth of effort, game runs well enough without extra work so we get "inconsistent" performance in games.
Or just work with a 4090, load the scene into vram and call it a day.
Why does disabling the cores increase fps?
Great take on this … if you take the marketing pressure from AMD away, it’s clear that the 7950X3D needs some additional optimization in Windows, much the same way that Intel worked with Microsoft to optimize their efficiency cores … it just seems like AMD was lazy and didn’t start the collaboration with Microsoft early enough. Hopefully it will get better with future Windows updates. And by the way, I’m not an Intel fan but you can’t help but think that AMD hardware is being letdown by their software development efforts (both cpu and gpu) … we need them to get better so that they can put pricing pressure on Nvidia and Intel.
yes but the intel cpu's have a scheduler built in, not with amd, they rely on several software solutions
Exactly, I believe that AMD was lazy … they should have developed their own optimizer or scheduler and made it part of the firmware that ships with the CPU’s … it makes me think that the decision to put 3D cache on only one CCD was a last minute decision (last minute in terms of Cpu manufacture times)
@@blackbirdpctech It' not about AMD being lazy but about taking responsibility. AMD is effectively dumping the scheduling responsibility on to Microsoft and other software. Intel on the other hand has an Intel thread director that takes responsibility from the software for the correct implementation of scheduling. Notice how everyone is blaming Microsoft for any AMD scheduling problems but similarly Intel get the blame for any of it's scheduling problems.
The 'last minute decision' idea is possible, but that would give strength to the possibility that AMD attached zen4 CCDs to 7800x3D because they had unsold zen4 CCDs lying around.
would you be willing to tell me what components you would use to make a gaming computer for around $3000? I want to do this for my step son who is a gaming nut and I would appreciate any help...thanks!!!
Another point of view, if the person can't be bothered to invest 5 minutes in setting up the PC by following simple instructions for this CPU then he probably is not a good candidate to assemble a PC and he should buy from an OEM. If he buy from somebody like Tech YES City then it is up to Tech YES City to set it up for that person and provide an install-medium (USB-stick) for a clean install with this setup (a simple script will do it) in the future if desired.
Can you bench mark the games that use L3 heavy cache? like Escape from tarkov?
The 7950x3d is a great hybrid CPU. If you needed productivity well it's like 90~95% the speed of a normal 7950x and if you want to just game. Then either manually set core affinity or just disable and you now have an effective 7800x3d... Unless the real 7800x3d comes out with higher clocks
It's such a great CPU you have to manually configure it and micromanage it to not get degredation. And it's also more expensive than a 13700K. So Great....
It would be great IF it were a hybrid CPU. It's not, and it does almost nothing correctly out of the box. As such, it's a total failure as a hybrid CPU and the Intel P/E core architecture crushes it.
13900k runs rings around it
@@anuzahyder7185 well i will hope so for intel's sake since it use almost twice the power : /

I don't think this is a true simulation a 7800X3D. Point to make is that the boost clock for 7800X3D is less than the boost clock for the 7950X3D on the 3D v-cache CCD. In addition, the 7800X3D has 96MB of L3 cache and 7950X3D has 128MB. Also, L2 cache sizes are different. The only way to tell how they compare is to have a real 7800X3D to test.
When you togle off the other cpu ship, you only use 96mb of cache… So this is quite accurate. In 7950x3d the v-cache ship is slow aka as slow as 7800x3d is suposed to be. And the non v-cache chip is the fast one. So simulation should be quite accurate. What we don´t know is how they bin the v-cache chips to 7950x3d vs 7800x3d. If they use better chips in 7950x3d it may be that the simulated results are better than what 7800x3d will deliver. We have to wait one month to see that.
The extra cache and clockspeed comes from the non-3d chip, the one you don't want games to run on, so the simulated numbers should be quite accurate.
AM5 3D CPUs with 2CCDs should have a built in hardware scheduler to properly assign tasks to cores, just like Intel did with their P and E cores. Not designing it and just selling these CPUs to general public is a kind of scam, imho.
I completly get what you are saying and for the most part I agree with you but splitting the CPU into just 8 gaming cores and 8 "work" cores is not what they did here. Yes 8 cores are meant for gaming and only gaming, but the other 8 cores are meant to work with the gaming core to provide you with the 16 cores when "working" If you only used the extra 8 you would get less proformance for "working" this chip is meant for someone who wants the best of both worlds. Perfect gaming and the ability to have 16 cores for a work load. It should have been labeled better as such instead of just the worlds best gaming but the 7800x3d will not be able to preform "work" tasks as well as the 7950x3d.
yeah but u should just get a 13900k in that case
I didn't feel like waiting two extra weeks AND spending at least 100 to 150€ more for the 3D so I went for the regular 7950X - that money went to an AIO cooler. I'd be fine with messing with core affinity but the fact that programs can just reset it on their own AND all the software "requirements" to even have it work properly are just too much. Maybe the 9950X3D will have dual 3D cache - AM5 will probably make more sense then.
Can someone explain to me in plain english, why is the more expensive CPU slower in most games?
Everyone doing click bait titles with "7800X3D" what a new low TechTubers.
Per Techpowerup "This contraption isn't a perfect simulation of a 7800X3D-the clock-speeds of the 7800X3D will be lower according to AMD's announcement, and boosting behavior may be slightly different."
It'd be nice to see this somehow accounted for in simulated demos.
I did not notice that under the announcement. Are you sure that is not coming from the 5.7MHz that the non v-cache CCD on the 7950X3D can reach?
@@Peter.H.A.Petersen Digging thru some reviews, the max boost clock of the stacked 7950X3D CCD is 5.25, whereas the 7800X3D max is advertised as 5.0

When this chip comes out I want a side by side comparison of these simulations and the actual numbers. So I know how hard I should laugh.
Well im sticking to my 5800x3d for the time being. At 1440p with my 3080 i dont think i need a better cpu. Also needing to upgrade my whole platform makes me really not want to upgrade
You should never upgrade two generations in a row, period, unless you just like spending money.

I love Tech YES Simulations!
At the end of the day Wendell stated, if you just leave the 7950X 3D alone it runs perfectly fine. Because sometimes you are going to need more cores.
I wish you would also include 5800 X3d
Any product that doesn't work well out of the box end-up on the discount department.
Monitor with bad calibration or a mouse/M.2 that required a firmware update to work properly also fall into this category.
AMD did create a small failure trusting software to handle access to the 3D memory so yep we might see it drop in price if people complain about it in a loud way.
