CPU Benchmark Performance: Simulation
Simulation and Science have a lot of overlap in the benchmarking world. The benchmarks that fall under Science have a distinct use for the data they output – in our Simulation section, these act more like synthetics but at some level are still trying to simulate a given environment.
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.
We are using DDR5 memory on the Ryzen 7 78000X3D 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.
Simulation
In the testing of our Dwarf Fortress benchmark, AMD's PPM and 3D V-Cache Optimizer drivers failed to detect that the Ryzen 9 7950X3D was running a gaming-focused simulation. However, the Ryzen 7 7800X3D with only one CCD was able to deliver outstanding performance in this benchmark. Similarly, in our Factorio benchmark, the Ryzen 7 7800X3D dominated and surpassed the previous Ryzen 7 5800X3D chip, as expected.
While the Ryzen 7 7800X3D did exhibit some limitations in other simulation-based tests, it's worth noting that this CPU was primarily designed for gaming and not for content creation. Therefore, we can excuse its lack of compute power in these tests. This is similar to what we observed in our Ryzen 7 5800X3D review when compared to its competitors.

Seems like the 7600x is the clear winner here.meacupla - Wednesday, April 5, 2023 - link
You should go see the results from other review sites as well.Anandtech's testing configuration seems to be bottlenecked in a way that makes the 7600X look faster than it really is.
7800X3D blows the 7700X and 7600X out of the water on other review sites.

I agree. The memory chosen 5200 44CL is not ideal and affects scores. They need DDR5-6000 at 30CL which is the sweet spot.Violet Giraffe - Monday, April 24, 2023 - link
A memory kit that costs almost as much as the CPU? I doubt this what many Ryzen 7000 buyers will run, at least in the near future. This why I'm inclined to go for Intel 13xxx, despite their higher power draw.army165 - Tuesday, May 16, 2023 - link
I picked up 32GB's of GSkill 6000mhz, 30CL for $120. I don't know where you saw that RAM was $450 but it's not.godrilla - Wednesday, April 5, 2023 - link
especially if you want to save money and buy a better gpu for eg.AMD Ryzen 5 7600X, MSI B650-P Pro WiFi, G.Skill Flare X5 16GB DDR5-5600 Module, Computer Build Combo
is$533.96 SAVE $133.97
$399.99 before 5% membership discount at microcenter. The difference saved can go from a 6700xt to a 6950XT which is going for $549 with cpu Combo and should easily double them frames.

Who would use such crappy memory 5200 cl 46 in a new build? For example at Microcenter you can get G .Skill Flare X5 Series 32GB (2 x 16GB) DDR5-6000 PC5-48000 CL36 for $140Wereweeb - Wednesday, April 5, 2023 - link
Ryzen 7000 only officially supports DDR5 speeds of up to 5200MT/s. Anything above that is overclocking and outside of their specifications.Anoldnewb2 - Wednesday, April 5, 2023 - link
And who doesn't use PBO with their memory?Anoldnewb2 - Wednesday, April 5, 2023 - link
I meant AMD EXPO memory profiles. If your reading this site, your probably interested in getting more performance from your system. also CL 46 is so slow
