Ryzen 9900X and 9950X Benchmark and Review: Is it Time to Upgrade?

[@dataterminal]

Windows is doing something strange. It's busy trying to load adverts into everything.

[@andljoy]

Everyone needs a threadripper to load all the ads !

[@doityourself3293]

windows what's to see where you are going in the games to advertise they plan on putting ads in the new games.

[@qwesx]

​@@andljoy Doesn't really help when your productivity software is Windows-only. I'll stand by this: asymmetrical CPUs where simple core scheduling can cause a massive negative impact is simply terrible CPU design. If you want to save power or costs then just buy a cheaper CPU - and you also get consistent performance on top for free as well.

[@enitalp]

As a game dev I can say that by default, windows can schedule the “main thread aka mainloop” multiple times per frame on multiples cores, same for any worker thread. Moving to another core is either costly directly : you have to copy all the registers, internal registers, stack, and the cache l1 , partial or total of l2 and l3,(and caches size is getting bigger and bigger, that’s a lot to copy), or do it “fast” and let the process ask for memory : copy all the registers, internal registers , stack, do not copy the cache, letting the process ask for a memory address get a cache miss, filling the caches for that call, making the first execution of the process on a new core, very costly than stay at least one frame, and better many frames on the same core. On console I always pinned all my threads to a specific cpu, on windows, yes you can see some gain, by pinning a thread to a cpu, but you could also see that the lowest fps is also getting lower, in some case much lower. The problem, windows is not a console. On a console we get a guarantee that a list of core are for the game, and that no system thread would run on those cores. On windows, you can pin your thread to a core, and run your mainloop as fast as you could, it works, for some time, until windows decide that your thread did run long enough, and interrupt you as soon as you make a system call , and that call, instead of lasting 80ns as usual can last 100, 400 ms , because windows decided to use “your core” for something else, trashing the cache at the same time. Cohabitation is possible, but it’s very very hard, and when you think you have the solution, you find that sometimes, when you start a thread, sometimes it start only 100ms later… those are the usual lags and stuttering in windows game. So thread pinning = good, on windows, it give some gain, but also some loss, that could be bigger. This is the reason most musicians prefer macOS, the thread scheduler, not having those 100ms lag than an app under windows could have. 100ms for a game or for midi sounds or wave, it’s a lot. And the cure, it to had a one or multiple frame delay, fixing frame rate but introducing lag. TLDR windows thread scheduler = bad

[@JJFX-]

Generally speaking, do you think there's a notable advantage/disadvantage to scheduling in Win11 vs Win10?

[@enitalp]

@@JJFX- I still need to try Win11.

[@enitalp]

PS: The "solution" on Windows is to not CPU starve the OS So, give the OS time to do whatever he wants, but at a time that "suits" the game engine. Usually by adding a simple sleep(1); The 1ms, in this case, is not guaranteed; it depends on the OS, The more starved the OS is, the longer the sleep(1) is. So, the game manages the OS by giving it a percentage of its time. (upside down world) It's not perfect or "efficient," as you lose "compute time," but it works. I have yet to try "for science." There are system functions to change if a core can be used by Win! What happens if I transform my PC into a quad-core for Windows and all the rest just for my code to profile actual performance?

[@tiedye001]

Does thread priority have any affect on this problem? Does the realtime priority fix it at all? I know nothing about this stuff just curious

[@enitalp]

@@tiedye001 Same as CPU Affinity; you get more time, but you "piss off" more threads with an "important" job, so when the OS can interrupt you, the lag can be violent. Thread priority is suitable for a 3/4 ms task; for example, if you want it done fast, it's not ideal for constant performance 100% of the time. This is why a console can beat a more expensive PC by 20% to 30% between a similar CPU and the same frequency (Rainbow 6 Siege), between Windows and a PS4, for example.

[@Cantimule]

@@tuckerhiggins4336 The reason you'd benchmark a $200 CPU using a rig with a 4090 is because you don't want it (and all the other CPU's as part of the testing to compare it to) to be constrained by the GPU. If you tried benchmarking a $200 CPU in a game and used a $200 GPU as well, all the CPU results on the higher end of the chart are going to cap out at the same framerate because the GPU is the bottleneck. The benchmarks are meant to compare one CPU to another using the same environment variables in order to show relative performance and value, not to show "how fast does this game run on my PC if I buy that CPU?"

Thank you Wendell for an amazing and truly honest review.

[@Kneedragon1962]

Michael Larabel at Phoronix loves them. Particular attn, the avg scores, like avg of all creator, avg of all database, avg of all games ... About the only thing the 9950 doesn't mop the floor with, is power efficiency. The lower 9ooo series do rather better there. There are a few outliers where the intel 14th gen does stunningly well, but those are outliers. Compiler performance is stunning!

[@tappy8741]

I'm guessing the 9950x can shine on power efficiency if power limited, maybe set tdp to 105W which would effectively be an eco mode on a 170W default tdp. I want to see those benchmarks. The main issue is memory bandwidth. If your workload uses avx512 in particular an all core workload probably easily saturates 16 cores, it likely saturates 8 cores, it's funny that 6 core zen5 may be the most sensible way to run these types of workload.

I can't believe after all this years Windows scheduler still does not fully support AMD's dual CCD layout so that AMD has to resort to crazy hacks with game bar and drivers to basically shut down half of the CPU you paid for to avoid performance degradation caused by suboptimal scheduling.

[@bosstowndynamics5488]

All these years? All these 1 years? Zen 5 is the first time AMD has had any need for special scheduling for symmetric dual CCD chips, prior to this it was only the 7900x3d and 7950x3d that needed advanced scheduling and most x3d buyers were going for the 7800x3d anyway. Yes, Microsoft absolutely should have fixed it (particularly since Linux already accounts for CCDs apparently) but it's not like it's been many years of wide deployment of the core parking stuff

[@MikeKrasnenkov]

@@bosstowndynamics5488 "symmetric" does not equal monolithic die where all cores have uniform access to caches and memory. As each CCD carries its own caches having threads reassigned between them randomly, or threads of a single process running on multiple dies incur significant penalties due to cache misses and synchronization. Dual CCD design first debuted in Ryzen 3000 series, or even earlier if you count 1st gen Threadrippers. So yes, all these years and Windows still suffers from these problems. I'm not sure how Intel does it with their non-uniform core designs, but it seems they were able to convince MS to care at least somewhat. While AMD's best effort is to hook up into game bar logic and disable half of your CPU.

[@bosstowndynamics5488]

@@MikeKrasnenkov Saying Windows "still" suffers from these problems is misleading - the performance penalty from communication between CCDs in everything up to Zen 4 for symmetric configurations was so small that pretty much no one noticed, so it really shouldn't be a surprise that Microsoft didn't bother to fix it. Intel forced their hands because all of their parts had 2 radically different types of core in them, whereas even AMD's heterogenous designs with Vcache (which have only been around for less than 18 months and are far less common since most gamers are going for single CCDs) will work just fine with scheduling misses, they'll just be slower. And the issues with the scheduler for symmetric dual CCD designs have only just now come to light pretty much today as far as the public is concerned.

[@MikeKrasnenkov]

@@bosstowndynamics5488 Why was the penalty so low before Zen 5 and suddenly so high now? Zen 5 should be pretty much the same what you call "symmetric" design as previous Zen architectures. What changed?

[@Osaka2407]

@@bosstowndynamics5488 All these years. Even first Zen had two CCXes. Now CCX is 8 core CCD but not always. Ryzen 7 370HX has 2 CCXes, one is 4 core Zen 5, second is 8 core Zen 5C. First Ryzens had 2 four core CCXes in one CCD. Ryzen 2000 was the same. Ryzen Threadrippers of 1st and 2nd gen not only had 2 CCXes per CCD but also used multiple CCDs. And ever since Ryzen 3000 launched, the basic configuration of desktop CPUs wasn't changed. It's still 1 IOD and 1 or 2 CCDs. TIt's been almost 5 years since 3950X was launched and like 7 or 8 since first Ryzens debuted. Intel launched Alder Lake three and a half years ago. And it's not the first time both AMD and Intel suffered because of M$. BOTH companies had to write their own drivers to improve scheduling on their CPUs because despite their work and continuous push, M$ refuses to make WIndows scheduler better. Even after publicly committing to making a fix. AMD integrated their driver within chipset driver and uses GameBar to assign game to the correct cores. Intel wrote APO doing just the same thing but, afaik just without the help of GameBar. If a Linux shows improvements and Windows doesn't while Linux doesn't even need the software hackery, it's safe to say the hardware is not at fault, nor is hardware vendor.

[@LeavenworthComputerServices]

Here's something we're seeing in a test of the 9950X compared to 7950X, which we did as a ProxMox test. Inside of ProxMox hosts, we're seeing a significant improvement vs. at the wall power utilization. But in Windows itself, when non-virtualized (not using a QEMU CPU) the benefits are not being felt in any real mode; we don't really test for gaming. Now, obviously, we're comparing a point that is below straight to hardware to hardware virtualized. But the benefit does show up, and that is interesting.

[@rangersmith4652]

Zen5 may well have potential, but I chose to follow Wendell's advice to buy a CPU based on how it performs _now_ rather than on some nebulous possible future capability. This morning, after checking the last round of Zen5 reviews, I bought a 7800X3D. It will anchor my main gaming PC for the next 2-3 years. Maybe Zen6 will make good on Zen5's unfulfilled promises.

But it surprised me that turning those OFF for gaming, made by 3DMark results better, and my gaming with Freesync enabled monitor with vertical sync limit to 120HZ on 5120x1440 rarely drop in CoD MW3 multiplayer (even for a second or two). My GPU is 7900XTX from Sapphire.

[@DanielKennedyM1]

This is interesting, I haven't heard about SRIOV and IOMMU affecting performance. You're not running Windows in a hypervisor? Do you have a ballpark estimate of how much impact it had?

[@bosstowndynamics5488]

​@@DanielKennedyM1I suspect that the entirety of the difference came from the software side - SR-IOV isn't even available on consumer hardware and the UEFI option is really just whether or not to let network cards report to the OS as multiple separate devices, and enabling the IOMMU doesn't change any of the performance characteristics of the chip. On the software side though, core isolation and related features mean that W11 kind of sort of does run on a hypervisor, by default, because it uses Hyper-V to sandbox some of the drivers and other system components to prevent privilege escalation. It's honestly one of the few ideas in W11 I actually like (assuming it's actually securely implemented), brings some of the security by virtualisation stuff from niche systems like Qubes to mainstream users, but naturally that does come with a bit of a performance overhead and that difference is enough that gamers who don't understand the security implications wind up disabling it (or of course power users who don't run sensitive workloads on their gaming system like the above commenter who knowingly take on the risk)

I've got a hunch that the improvements that have been realised on the ARM side in terms of efficiency are probably at least partially due to Microsoft having to strip out a lot of 30 year old junk and could potentially be realised on x86 too if they got their act together and made Windows work properly instead of focusing on creative ways to juice their metrics and shove ads in users' faces

[@JEHendrix]

I’m not a gamer, just a photographer and fine art printer. So, even with all the bad news and confusion re the Ryzen 9000 series, I decided to go ahead and replace my 7900 with a 9900X anyway. I have an MSI MPG B650i EDGE WiFi motherboard in an open case with an ID-Cooling SE-207-XT air cooler to which I have attached a second fan. The 7900 runs with DDR5-6000 memory, Game-Boost and the TDP elevated to 105W. It pulls 142W running Cinebench R23 with a high temperature of 79C for a multi-core score of 27550. When I replaced the 7900 with the 9900X, with the BIOS cleared except for EXPO, Cenibench R23 scored it at 32214 with a high temp of 81C. That’s a 17% improvement, much better than I expected. Think I’ll be keeping the 9900X and seeing how much I can wring out of it with a better cooler. I have no intention of playing the core parking game. BTW, B&H is selling the 9900X for $50 less than everybody is reporting. They also pay the tax if you use their PayBoo card. No connection to B&H, just a happy customer for many years. Some good news re the 9000 series is overdue. I appreciate that gaming drives the technology, but other users make up a large part of the marketplace, so it seems wrong for gaming to influence the whole picture. Even though AMD fumbled the rollout, the 9900X is still a great CPU for non-gamers.

If you want to max out the RAM on AMD platform, going with the ECC is probably the best way to do so. 48Gb ECC UDIMMs are available and the prices are decent at $200-250/ea. I mean, with that much RAM, random bit flips from the background radiation are inevitable.

[@bosstowndynamics5488]

Depends on what you're doing, the extra bit flips from large DDR5 sticks are supposed to be handled by the ubiquitous on die ECC anyway.

Thanks for going over the 4x dimm stuff. Very very helpful.

[@newbiegain117]

The only channel that covers 4k resolutions

[@samuelrodgers2742]

The reason that 4K is not commonly tested in CPU reviews is because 4K is primarily GPU-bound and GPU limited. You want to create a CPU bottleneck at 1080p with the GPU maxed out with no upscaling which allows different CPUs to be easily compared

[@robertmyers6488]

Conclusion: Windows is a mess. Is gaming on Linux advantageous over Windows with these new processor in total?

[@DanielKennedyM1]

Almost certainly, and arguably was with the previous gen CPUs as well, though it'll always come down to Linux compatibility for any particular application. I wish Wendell would test Factorio. It's one of the few games that is heavily bottlenecked by memory performance, much more than CPU/GPU. Its (native!) Linux build has always run better than Windows, for a variety of reasons - the most compelling being Linux's support for Large Memory Pages.

[@robertmyers6488]

[@WokeSoros]

After jumping ship from MS advertising and spying platform I was shocked to see that Linux Gaming is now not only viable but often on par with Windows running through proton. I find it not at all surprising that Windows gets outclassed by Linux on these new processors, as Linux is an actual operating system with a strong focus on performance as opposed to tricking the user into tracking its users and sending them ads. Where you put your dev efforts matters. (Also Windows is a house of fucking cards)

[@markldevine]

My favorite review. For my uses (with "gaming" about #9 on my list), this review was what I was looking for. Keep up the good work!

[@diamondblack3776]

I'm still slumming it on an X99 platform, running everything, all those games plus more just fine. What helps is a 4K TV as you can use a desktop window mode for gaming, the size of the desktop window is similar to a large monitor (eg. 1920x1080p window is 27 inches).

[@sfalpha]

If you want to run very high memory clock/timings, keep in mind that your memory will degraded overtime if you running at high voltage (even it stamped to your EXPO and XMP profiles that they designed to run on that voltage). You can run DDR5-6000-8000 at 1.35 or1.4v but it may not able to run at that speed after 2 years because it degrading very fast. Some Mainboards also inject higher voltage than you set in the BIOS. I found some ASUS boards giving DIMM 1.38v instead of 1.35v setpoint.

[@Electrodudimanche]

For the memory, I had problems with 2x2 sticks on my AM4 with my 5800X3D, the system would not boot AT ALL, if a specific stick was not in the right slot. Once booted, I could apply the 3200Mhz without problems. They layout is like you show, each pair on the same channel ( and there's a specific order, i lost hours trying to understand, and just bruteforce all the possibilities until it worked), unlike what's specified in the manual.

[@woofwoofwoofwoofwoofwoofwoof]

Damn it was actually 9:30 PM when I started this video, you creeped me out 😮‍💨

[@martinrasmussen6634]

Thanks alot for the unbiased review. You brought up alot important subjects, us mostly none gamers realy likes hearing about. Like what to expect on DDR5 on 4 channel setup. I am a developer, so i use my system mostly as a server. Currently i have a 5950x, which is a fine little beast for this. But i see it being constrained on memory (DDR4) bandwith, when i start to load the 16 cores up, in my applications. I tested with a 7950x3D, and the way my programs allocate mem/cpu cores, doesnt benefiths this alot vs the 5950x. Therefor i hoped the 9950x woulld be a worthy upgrade. I had hoped we had seen a 8xZen5+16xZen5D cores edit, but seems that was a dream not coming true, before Zen6. Likewise i had hoped for a IO die with 1GB+ L4 cache to be shared with gpu/cpu, bit like broadwell, intel cpu... but no. So even Zen5 is both faster and cheaper than Zen4, i guess its going to be another wait untill Zen6 gets out... Again, thx for review.

[@rheh2570]

this channel brings meaningful review for me.. 1. linux based testing for PRODUCTIVITY use case. 2. non-gaming and balanced summary to tell us if it's something worth considering. I'm planning to upgrade from 3700x to the 9700x

[@joepearson6644]

Just installed the Ryzen 9950X into my board its insane 😊

[@Floreum]

I appreciate this review. I'm someone who just started buying my parts in preparation for this CPU. I'm coming from the Intel i7-7800X and desperately need a new CPU, but when the rumors started circling around about the 9000's I decided to delay building a new PC. Seeing all the doom and gloom around it was a little concerning, but I mostly use Blender/productivity software so seeing the boosts there had me pretty happy, gaming is secondary, so as long as the game runs better than what I currently am dealing with then it's good for me. Though I gotta say I've been thinking of checking out Linux for a while now since I don't agree with the crap they are pushing into Windows. Maybe I'll do a dual boot so I can check it out.

[@Handler9]

finally a comprehensive review. Gen-on-gen improvement is unimpressive, but fingers crossed it's a stepping stone to something better (10050X perhaps?)

[@TheNerd]

If you ask me, the most valuable info in this video was the little "RAM break" talking about how and which ram runs, since Ryzen CPUs basically "stand or fall" with the RAM choice.

[@ReHWolution]

It's a great take with solid hypothesis on why Zen 5 isn't performing as it should. Anandtech did a great job at analyzing inter-core latency, maybe it's not the fact that they used the same cIOd they used on Zen 4, maybe it's windows 11 scheduler that isn't supporting this new uArch properly yet?

[@mzmz9355]

Thanks for another look at the zen 5 :-). The nice follow up would be to dive deeper into new zen5 microarch Vs win 11 basically to show/explain the current seemingly strange benchmarking results ... and to see what could be done to win 11 to use zen5 architecture fully.

[@zen_xenomorph]

In regards to administrator providing better performance, this has been known for many years amongst the game cracking scene. Many cracked game installers will run the game as admin by default. There's also other reasons for this, like trying to reduce problems people may encounter. But this can obviously be abused by dodgy files. Running as admin certainly wont provide performance benefits with every single game, just occasionally. I've no idea why this happens, but it's been a thing for a very long time.

[@Alexandra-Rex]

I'm running a 2950X as a streaming PC, so I have some PCIe cards in it for capture, and there might be other things soon. The 5600X in my gaming PC isn't THAT far away from it in processing power, and it's fascinating. For processing power, I could definitely go with many AM4 and AM5 CPUs for the streaming PC, but I'd lack the PCIe lanes, so any upgrade will be very expensive.

[@vidagogo9829]

This CPU generation is getting some of the most different opinions across the lineup of critics I've seen in a while. Steve: "Meh." Linus: "Cool!" Level1Techs: "Get it for an upgrade of three years or more." Hopefully the X3D ones show a better, more obvious improvement. My opinion is that you just don't get the performance for the value at all. I guess I'm mostly with Steve (GN).

[@jackcolt6875]

Interesting point that you make about Linux vs. Windows game performance. I have been seeing hard evidence that GPU performance (NVIDIA) is better on Linux machines over windows for AI oriented tasks, like embeddings, for example. My theory is that that CUDA driver performance is heavily optimized for linux due to heavy usage in Transformer model training by the likes of OpenAI, etc.

[@prosetheus]

Thank you for this insightful and nuanced review. Truly in a class of its own.

[@MikeBob2023]

Thank you for the comprehensive look-see, Wendell. 🙏🏼 Your views on these new parts (together with those of _Hardware Busters'_ Aris) are a *refreshing* (see what I did there?) departure from all the _weeping & gnashing of teeth_ that I've borne witness to on KZbin lately. 👍🏼 P/S: The check is in the mail. 🫰

[@reno922guy8]

Great video, but it doesn't consider price. In some of these benchmarks, the i7 is actually outperforming the 9950x. So why wouldn't anyone want a i7-14700K at half the price?

[@gudenau]

I'm definitely not upgrading right now but I'm excited for when I eventually do.

Just bought 9950X and an MSI X870E MPG Carbon WiFi motherboard and the USB disconnecting issue still exists/has come back, meaning the platform is unusable.....yes, the one that surfaced over 3 years ago when X570 was launched! Such a pain, an no influencers/tech sites are covering or mentioning this so would be good if influencers got together and held AMD and motherboard manufacturers accountable for this!

[@marios3761]

Hey Wendell, after reading about the "Administrator" account performance gains, my thoughts went directly to the large page support. It's locked behind a security group policy AND requires to run the exe elevated. The GPO is under Computer configuration -> Windows settings -> security settings -> Local policies -> user rights assignment, called "Lock pages in memory". Linux iirc has large/huge pages support by default This was/is commonly used for mining applications where the gains are pretty similar, now I know there are some stability implications with memory allocation, I can't confirm if that's the main difference from the disabled Administrator account Since I don't own a 9xxx series, maybe you could test if this is the setting that gives that extra performance?

[@superjuddy]

thanks for the info Wendell

[@lunks]

One thing I haven't seen: If you use something like Proxmox, NUMA correctly configured to use a correct CCD and no SMT passed on to the Windows VM, how does the game work? What about Linux? I find that sometimes you can tweak KVM to do stuff that can get pretty close to optimal performance in baremetal. Thanks for the great work!

[@Alexandra-Rex]

Watching this, hearing you say Windows is doing something weird, and having just seen Hardware Unboxed's video about what I expect is the same issue is interesting.

[@N1CKSO]

R5 3600 still running strong here. At 1440×3440, it probably still has headroom (paired with a 3070 tie)

If Microsoft decide to optimize their OS and vendors decide to do it as well, as they should, these CPUs will age like fine wine.

But never buy something based on potential future updates. More often than not the wine just becomes vinegar.

[@v000000000000v]

@@aelderdonian that statement is generally true if the update is promised by the same company that sold you the hardware, where the company is not financially incentivized to provide you software updates down the road, but we are talking about Microsoft that needs to fix their OS and specifically their scheduler, AMD has already done their job and their hardware works fine on Linux, it's 100% Microsoft's responsibility to fix their shit here

Great video

[@Gaming_Biker]

I’d like to see more about how Windows could be the problem w/ consistency, since Jayztwocents was stating there was wacky behavior between Intel & AMD non-3D processors, AMD 3D models were performing similar to Intel’s offerings. Jay was wondering if it’s how games are handling the multi chip architecture of the 3D models vs their non-3D counterparts, think single socket vs dual socket systems as an example what thought line he’s going with. My thought after your video is, what if Jay’s theory should be in relation to the CPU & Windows vs the CPU & games. As an unrelated side note, I’d double check your test result slide titles since there are few that the title said 1080P when you were showing the 1440P & 4K results. Appreciate the review!

[@psommer4218]

It would be really good to have a dedicated video on RAM for AM5 + Ryzen 9000 / Zen 5 (+X870E).

I got Rocket Lake because of AVX-512 for RPCS3. Love my 11400, but even it can light on fire with a Z board and full limits removed, especially with AVX-512. 150W limit for that chip, 175W burst for my twelve year old Hyper 212 Evo (with new fan) before I get uneasy with temps.

lol on Zen 2 currently getting around 70-80 fps while software encoding. There's drops here and there, but it's not too bad. I think I'll give it another generation, I'll see what comes out in the next year or so.

[@victormtzc]

I like your part about stable. I used to have a 7950X which got replaced for a 7800x3D. Both CPU were unstable using DDR5-6000, they work ok most of the times but sometimes I noticed my computer to shutdown and start again. So I figure it out at the end, I set my CPU wattage at 65Watts, this make stable my CPUs and I was able to use my DDR5 at 6000 MTS. Actually my 7800x3D was faster at this settings at Cinebench R23. I think Intel can get more power and be stable but TSMC silicon cannot get a lot of power and be stable. AMD need to stick on the low power and frequency spectrum. I really believe is a very weak product, not real value on these new chips, probably same level as Intel 14gen (refresh), unfortunately for amd the architecture changed but not the numbers on the test. I think Intel will have an easy time beating AMD with Arrow Lake. I also want to see a Qualcomm CPU on the desktop area. I am typing this from my Qualcomm X - Elite.
