The AMD Ryzen 9 7950X3D Review: AMD's Fastest Gaming Processor
by Gavin Bonshor on February 27, 2023 9:00 AM ESTCPU Benchmark Performance: Science
Our Science section covers all the tests that typically resemble more scientific-based workloads and instruction sets. For our 2023 CPU suite, we've also added SciMark 2.0 which measures numerical kernels and various computational routines found in numeric coding.
We are using DDR5 memory on the Ryzen 9 7950X3D and the other Ryzen 7000 series we've tested. This also includes Intel's 13th and 12th Gen processors. We tested the aforementioned platforms with the following settings:
- DDR5-5600B CL46 - Intel 13th Gen
- DDR5-5200 CL44 - Ryzen 7000
- DDR5-4800 (B) CL40 - Intel 12th Gen
All other CPUs such as Ryzen 5000 and 3000 were tested at the relevant JEDEC settings as per the processor's individual memory support with DDR4.
Science
Our science tests focus on scientific-level workloads, and from the above figures, the Ryzen 9 7950X3D performs respectably, as we would expect. The additional 64 MB (128 MB in total across both CCXs) to one of the CCXs does actually provide some benefit in these types of workloads, at least compared directly to the 7950X.

I noticed that Ryzen 3000 is mentioned several times, but not included in any of the charts. It would've been nice to see one of those in there.kayak - Tuesday, February 28, 2023 - link
I'll wait benchmark with the cache preference in the bios. I'm not fan of these additional layers like microsoft game bar, some people disable it and it looks like it doesnt help for factorio anyway. If bios settings set to cache preference can fix most of problems i'm fine, not everyone use windows.iRacer - Tuesday, February 28, 2023 - link
Your V-Ray bnenchmark scores are all over the place.A current 7950X scores on average 29k vsamples.
How are you getting these values, and how can the reader know the method is proper, given you're sitting on double the real values?

Gavin, once again: your V-Ray benchmark score do *not* reflect what can be seen here (https://benchmark.chaos.com/v5/vray?search=7950x&a... by TWICE the amounts.How are you reaching these values?
Do i have to ask you officially via email, or can you reply directly?
I am *clearly* an intersted party under anonymity.
If you read and delete the comment, you are well able to reply instead.

nevermind, nothing was deleted, but the "link" above the post doesn't work and leads to a 404.iRacer - Tuesday, February 28, 2023 - link

Hi iRacer. I'm certainly not ignoring you.I'm pretty sure I replied to a similar comment in another review.
You are more than welcome to reach out to me via email for a discussion, but we are using V-Ray version 4.10.06
As per our 5950X review/testing as per Dr. Ian Cuttress here: https://www.anandtech.com/show/16214/amd-zen-3-ryz...
This correlates with the result/data I have in my testing in this review. You also can't compare results between different versions of the benchmark.
I'll run the latest version when I get a moment tomorrow and let you know. In the mean-time, feel free to email me if you wish to continue the discussion there. It's easier to keep track of via email than it is to trawl through comments.
Thanks!
P.S.: The only time I'll delete a comment I've seen is if it's spam.

"the Ryzne 9 7950X3D doesn't quite hit"Also, this single-sentence paragraph (below) appears on both page 4 and 5. Maybe it doesn't belong on page 4.
"In the encrypt/decrypt scenario, how data is transferred and by what mechanism is pertinent to on-the-fly encryption of sensitive data - a process by which more modern devices are leaning to for software security."
Thank you for your great coverage.

AMD's core efficiency is out of this world. The 16 core 7950X3D performs at the same power level as the 6 core 7600X. This is unheard of and unimaginable!Silver5urfer - Wednesday, March 1, 2023 - link
Late to commment, but I already mentioned.3D V has it's limitations. AMD cannot improve this on Gen 2 with any Clock boost or such. It has same downsides, the Base clock reduction and Max Clock reduction. And the Unlocked Multiplier lock.
This processor is only for those "Gamers" And it does not make sense on the 7950X3D at all. A loss of TDP power window, loss in every thing that scales with Cores + Clocks.
Also Ryzen 7000 / Zen 4 is ultra optimized by default, it has super low voltage. 1.2v max at such high insane 5.x GHz clock rate vs Zen 3. TSMC 5N is a massive gain and also Zen 4 optimization. Now the X3D runs at high voltage. This is opposite of Zen 3 X3D, as 5800X3D ran at 1.3v binned and stock was 1.4v. Now roles are flipped. Meaning Zen 4 is at it's maximum potential.
Ultimately the choice for any PC DIYer is to get Zen 4 over RPL because Intel LGA1700 socket is an engineering failure. You should not resort to modding with Contact Frame on a $700 Mobo. Period. Zen 4 has a limit on PCH Chipset speed, the X670 apart from that, no downsides. I'd pick 7950X over any Zen 4 processor for a Zen 5 upgrade. RPL Refresh is not going to change socket ofc and not gonna do massive changes either, at best DLVR, optimization on TDP and optimization to Base and Boost Clockspeed. Intel 7 is also at it's max, plus it's an EOL design. Look at ADL vs RPL literally they gave E cores garbage and added Cache to have "Marginal" boost in games. and E cores to accelerate MT workloads. Pathetic. And now RPL refresh literally another BS Single digit gain. Look at Zen 3 vs Zen 4. Ultimate lead.
That said, I'm only looking for 7800X3D because it has higher TDP and almost same Clock Rate. Still capped Multiplier, anyways AMD processors are not good for tinkerers that much since you cannot control Clock rate and cannot have fixed Clocks either. At best Curve Optimization and DRAM tuning. So if you are into that stick with Intel.
