[@AyoKeito]

I seriously wish it would be closer to 7950 in gaming, rather than my current 5950. If that was the case, i'd change platform simply to install more GPUs for other tasks while i'd still be able to game at pretty much best performance. But unfortunately current results show it's still more sensible to run a different PC for more GPUs. It's a shame, i was ready to shill out a stack of cash! 🥲

[@Splarkszter]

​@@AyoKeito If you just increase the graphics you don't even need to bother about that, and remember the why it runs like that is because of the frecuency. Anyway, it's waaay cheaper to just have multiple Desktop systems if you aren't a server company struggling to fit more computers on the same building.

[@fleurdewin7958]

Threadripper has always suffer from higher memory latency than the consumer range Ryzen. Even in Zen 2 Threadripper, they are always +8ns memory latency from regular Zen 2 Ryzen with the same memory timings in AIDA64. Games love low latency memory. And mandatory use of Registered DIMM on TR 7000 series hurts memory latency even more.

[@AceStrife]

@@Splarkszter "If you just increase the graphics" Sorry, this is a fallacy. GPU performance will always top out at something; you can't possibly increase it any further. And if you do (ie; 8k downsampling), you're just dragging the overall performance down from something it could've been instead (ie 60 fps vs 120fps). This is even more important in emulation, which is extremely CPU dependent for good performance. As someone with a 4090 and 5950x (waiting for 8000x3d), I am constantly CPU limited while trying to reach 120Hz, irrespective of graphics options. And RT just drops it down even further because it still depends a lot on the CPU. If all you have is a 15 year old 60Hz monitor, then sure, that's a different discussion. But anyone playing modern PC games in an era of 500Hz monitors is probably expecting 120Hz+, and both the GPU and CPU need to be strong for this to happen. All of GN's CPU benchmark graphs show this issue very clearly. Wish they'd run some emulation tests though; no outlet I know of does this.

[@brandoncoventry5662]

@@Alklaine Excellent question! Truthfully it's model dependent. Often times in molecular dynamics, you have linear and nonlinear increases in complexity. In the linear case, it will be 1:1, and we try to linearize models as much as possible. However, you sometimes can't get around nonlinear models, where you might get a 1:0.5 increase. However, GN has done a great job of benchmarking common models, so we know where we roughly stand on a processor by processor basis, and then it's up to us to do the model fine tuning. But what has been shown here allows me to make an educated decision based on the model complexity I use.

That's an interesting thought. Yes.

[@ellejharmsen4801]

As a molecular simulation PhD, I also loved seeing these workstation tests included. Especially Lammps is really relevant for me. I actually think that the testcase in lammps is also molecular dynamics (just like namd). They just implemented some of the calculations/parallizing different. What might be important to note is that in my field we topically run simulation 3 till 5 times with identical settings, just different initial configurations (results here have statistical value). So to me seeing the results of the 32cores compared to the 64 cores set up as 2 simulations next to each other would be very informative as well. (Or both running 16 thread simulations up till the cpu is 100% loaded would be good too). I would be interested in what the CFD people here would think of that.

[@theicebeardk]

Thanks GN for the test results. With the ECC enabled for the regular ThreadRippers this proves to me that they are a viable alternative for a workstation for software developers rather than CAD or simulation stuff. For those sort of workloads you need a high core count (and great I/O) and as proven by the valuable Chrome compile test a switch from the existing Threadripper and older Threadripper pro desktops for developers would translate directly to higher potential productivity for those working on projects of that sort. For those sort of workstations the cost is not the issue most of the time. Personally since I do make money with my PC but also use it to game in the evenings the Threadrippers are now on my to buy list some time in Q1 next year likely. As for cooling this looks like a fit for the Icegiant cooler or an AIO from alphacool (which is what I use now).

[@ivimas_]

As a software engineer, I'm inclined to think the real world benefit for development work/code compilation is rather minimal compared to something like the 7950X. The reason being that you mostly don't compile the whole project when you're working on it, only the modified parts, and so the time required is likely to be very similar for both processors. A more server-like deployment would make more sense, if you can keep feeding it enough work to actually pay itself off.

Thank you. I was hoping for more single core testing, due to the experience of using the cpu in programs. I have a 3970X and was hoping to see if the 7970x would be closer to a 14900K or similar in After effects etc compared to the 3970X - Because a lot of threadripper users still need good single core performance in addition to the multicore - since these are not meant for servers (I use mine for Corona rendering + photoshop and after effects). . A regular Cinebench single core comparison would have been sufficient. But, based on your photoshop benchmark I guess one can expect slightly better than 3rd gen threadripper but nothing near 14900K...So I will wait and see how Arrow Lake and Intels 5nm lineup will hold up and ifIntel will give us a better multicore offer - before buying another threadripper.

Amazing tests, it's interesting to see how well those CPUs perform on code compilation, because despite being a highly “parallelizable” workload, at the end of the compilation pipeline, in which you have to assemble a single artifact (or a couple of individual artifacts), compilers and linkers are very reliant on the performance of individual cores. And those CPUs are clearly worse at single-core performance (not only because of power and thermal concerns, but scheduling gets harder), but they save so much time by going through the parallel bits extremely fast that, even if those CPUs take longer to go through the non-parallel bits, it's still faster and more efficient on the job than the lower core-count counterparts. It still like you said, you have to evaluate whether your workload takes advantage of it or not, and also be aware that there's a difference of highly multithreaded workload and highly “parallelizable” workload, the latter benefits way more from high core counts than the former, which commonly has more interdependency between the threads, so one thread stalling may negatively affect the others. Also I'm a little curious to whether those CCDs are as powerful as the customer lineup or not, how the gaming performance fare if you were up to have only one CCD enabled. Yes, it's crazy to buy this monster and proceed to disable all but one CCD, however the question is whether those cores can hold higher clocks for longer if they were not power and thermal constrained.

One thing I've been wondering is why the 7950X3D isn't on the blender efficiency charts, especially when it appears that it would be as efficient if not more than the 7800X3D. It pulls ~62% the power of the 7950X and is about 7% slower than it in Cinebench. Using the 7950X3D review video for efficiency scaling, it would sit at basically 17.6Wh which is insanely efficient for consumer parts.

[@AK-Brian]

I was going to ask about the same thing. It looks like it was omitted unintentionally, but would otherwise be the top scorer for efficiency in that test after the new Threadripper parts. I'd love to see where it officially ends up with that test metric.

24:05 the financial and probability simulations are very important for machine learning - whether that's training or inference, depending on the model architecture. It's a very big deal for ML but even bigger for time series data analysis in market dynamics when you assess a large system of signals and indicators which compare to one another and are compared across several time scales in addition to many different products whose price action is being recorded. Log complexity on millisecond updates across dozens or hundreds of items needs a ton of processing if you don't want to miss out on an arbitrage or trade intraday algorithmically.

Thanks for the detailed review as always! Are you planning on a thorough review of the 7960X as well? Especially if you're interested in video production workloads, the 7960X looks on paper like it might hit a sweet spot: you get the lanes of Threadripper for a second GPU, dedicated video output, high speed networking or storage, and higher clocks than the 7970X or 7980X, at a much lower cost (according to Puget, the 5965WX was almost tied with the higher tier 5th gen Threadripper for content creation). Those features would make it the ideal CPU for a lot of video professionnals. The inclusion of Resolve benchmarks would also be really cool, although your test suite is already a lot of work, it might help out quite a bit of people

[@DemonicPoker]

Another great and neutral informative review. I'm one of the people needing these beasts for daily computations, so I'm excited to learn everything before eventually ordering one. Would you have the possibility to make some Passmark tests with the 7980x and 7970 as these scale very well how my own workload will fare against other cpu's. Doing a lot of 'monte carlo' style based works, so if it's similar to the financial monte carlo you ran, it's super promising!

[@GamersNexus]

Can you give some more background on why/how Passmark represents your work? That'd help us in planning (and explaining it if we introduce it). Can you give an example of how your work relates to some kind of real world "output" or result? What does it mean for you if a CPU is faster? That'd help a ton. Thank you!

[@DemonicPoker]

@@GamersNexus Myself and a lot of 'pokercolleagues' run a lot of computerized simulations, some kind of Monte Carlo algorithms to build our strategies. When we look at the internal benchmarks solves we run in our software, we see that they relate very much to the passmark scores in general. Off course there are some small exceptions (as always) - usually related to the number of cores/threads. ("Generalized" our simulation softwares run faster the more cores as a very simplified explanation but the scalability relates very much to what we see in passmark - besides a few exceptions)

[@Petercubic]

As someone who purchased the 3970X and is planning on building a 7970X machine, one thing that was interesting to me was the inflation comparison between the two parts. I know it was only a couple of years, but I purchased my 3970X in March 2020. The comparative purchasing power today would be about $2,370. So, yes it's more expensive, but so is everything I guess. Just an interesting comparison to make when you're looking at high value parts where the small amount of inflation actually shows up in a reasonable way. Thanks for the great content as always!

[@Jodlauspc]

B-S, binomial and Monte Carlo are three of the most basic derivative (options) and forecasting models: they are very useful, and depending on the dataset Monte Carlo simulations could take a while. At university some teachers did not have enough horsepower to run them real time with lots of references and multiple (6+) graphs updating simultaneously. Running Excel with 30+ Binomial decision trees, while calculating the resulting Black-Scholes pricing for each step, and having their Greeks update live needs some CPU power to do it.

Please, GN, compile and post your complete benchmark charts on your new website!

This is especially important for PC cases and CPU coolers, where some very old models still outperform many new ones.

I'd love to see benchmarking on VMs running on the threadripper chips. i can image another use-case for them is running small Slimclient servers for small companies who don't wanna dish out 100k for an enterprise solution, but who still need decent processing power for say, 8 different stations simultaneously. with 64 cores you could be running 9 different "6 core" MVs natively off hardware with a whole 10 cores leftover for background tasks. not to mention all the PCIE lanes that could be running storage in RAID to making disk writing for the VMs redundant and instantaneous. that could be a gamechanger for small businesses.

A Ryzen 7 1700x is worth about $50, while a similarly-aged Threadripper costs about $30 more _and_ requires a special motherboard. In conclusion, you might expect that a Threadripper part would be good for gaming after a few years, but given the actual cost to get one, you'll always be better off with a newer Ryzen 5 or i5.

[@GamersNexus]

Well, not always. For mainstream use, definitely. But there are professional use cases where current-gen R5/i5 parts just won't do what you need in heavy enough workloads.

[@IndellableHatesHandles]

@@GamersNexus That clarification is important. I meant for gaming, of course, and made that comparison because only older Threadrippers would have a similar platform cost to an i5 or Ryzen 5. I guess I didn't make that entirely clear.

[@guiguipau]

@@GamersNexus Yes but : you need more compute power? Buy anything - including EPYC or XEON - for pro use that matches your compute need and fits your price range, and get a mainstream CPU - Ryzen, i5, whatever - for everyday purpose. It will be both cheaper and a better experience. HEDT is dead, and while these TR 7000 and 7000 PRO themselves are good, the cost AND lack of versatility of the platform, mostly through the absurdity that TRX50 and WRX90 are compared to any decent EPYC 9004 mobo for instance, render the platform a basic scam. I consider HEDT dead for now, and if it weren't for the scam that DDR5 currenly is (come on, it's been 2 years and we don't even have 64 GB mainstream udimms) and if we at least had these dimms, where you could enable 256 or 512 GB standard DDR5 in 4 slots, this would not even be a discussion : you need real professional feats like tons of PCIE lanes, compute power and at least 1 TB ram : get a server CPU and board. You're a prosumer doing rendering, huge labs and prototypes? Get a Ryzen 9 or an i7 / i9 and 256 / 512 GB DDR5. Let's be real : with CPUs normally progressing in terms of compute power, by the time Zen 5 / Arrow Lake or Zen 6 / Nova Lake are out, if 64 / 128 GB DDR5 udimms are out, this pseudo HEDT is probably dead. People who need more of everything will go to server chips. People who only need more ram will stick to mainstream.

Thanks Steve n team, this helps heaps with my cost benefit forms for management. they want to see number/bar go up mean workers work harder/less downtime

Small point: The TR parts don't have more cache than the regular 7000 series, the total cache doesn't matter. What matters is cache per core, and that is identical except for the X3D parts. If they decide to release X3D TR... yeah lol. But those won't have more cache than the 7800 X3D per core either.

[@5467nick]

You are correct. I wonder if the reduced cores per CCD models (or if disabling cores in each CCD manually) would make a difference. The 24 core part has the same L3 as the 32 core part, granted that's still far from the cache per core of the X3D CPUs. I doubt AMD will sell X3D threadrippers since productivity workloads don't tend to benefit from it. Then again, AMD does sell a few EPYCs with the extra cache, so who knows? Maybe someone will at least try to get one of those EPYCs into a board that allows overclocking. Some people did it with the older EPYCs.
