The AMD Ryzen 9 7950X3D Review: AMD's Fastest Gaming Processor

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 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.
Simulation
Looking at the results of our simulation-based tests, the Ryzen 9 7950X3D once again performs respectably across these tests. We would have expected higher performance in our Factorio benchmark, as the Ryzen 7 5800X3D and its 3D V-Cache did yield some impressive gains. This is likely due to the AMD PPM Provisioning and 3D V-Cache driver opting for frequency over cache when running this benchmark. That does show a little bit of a pitfall here for AMD.

This feels like there are gapping holes left to be examined, specifically with the scheduler/drivers and Windows 11.If you do these tests using manual BIOS settings, what changes?
This article is not helping me make a buying decision when I have this article only to compare current CPU offerings and there appear to be issues with the CPU software.

I'm still wondering how well would this cpu perform having heavy load of both a game and non-game running at the same time - most typical of the latter being e.g. OBS using x264 at medium or slow presets.Would the threads be assigned correctly ? Or would that be a mess as both CCDs would be unparked.
