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

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.

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.

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.
