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.

Literally every person with a brain is using memory that is technically "overclocked", and has been for over a decade. XMP/DOCP are overclocking... they're also mandatory for decent performance and a realistic test setup.NO ONE should be using 5200-CL44 in 2023.

Yea it kind of defeats the point on having otherwise state of the art hardware.erotomania - Tuesday, April 11, 2023 - link
I haven't much liked that part of AT testing for a while, nor the explanation.elajt_1 - Friday, April 7, 2023 - link
And yet AMD themselves suggest 6000MT/s as it is the sweet spot according to them.spikebike - Wednesday, April 5, 2023 - link
Can you RMA a CPU and/or motherboard because it doesn't like your DDR-6000?Do you include over/under volting? Exotic cooling? Pushing things hard enough that system reliability is compromised? Crazy large power supplies?
Or do you compare all CPUs/platforms with their posted specifications?
Comparing AMD *AND* Intel at their posted specifications seems fair. After all not everyone overclocks, and I don't particularly care if AMD or Intel is better at overclocking. After all some people actually like reliable computers and might actually care more about ECC memory than performance from overlcocking.

That's a fair comment, but these are enthusiast level parts after all.I suppose the solution is to show performance in both scenarios.

"I suppose the solution is to show performance in both scenarios."In an ideal world, it's something we'd like to do in some fashion. But it would double our testing workload, which isn't viable.

That's also fair enough. I appreciate the time taken to address comments.elajt_1 - Friday, April 7, 2023 - link
The people who gets these CPU's witout running OC memory can most likely be counted on one hand.elajt_1 - Friday, April 7, 2023 - link
Expo and XMP profiles will work on most systems (if not all), up to a certain speed.
