Processors

[Teadrinker]

Hello

I am a 7900X3D user who uses Linux as OS. This CPU has been very good yet when compared to Windows, it seems its 3d v-cache technology is non-existent on Linux! Is AMD aware? 

I personally have tried disabling CCD1 through BIOS (6 cores without 3d v-cahce) and testing game performances and noticed 0 improvement in all the games that I tried.

Can AMD please support Linux 7900X3D users?

Thank you very much.

Here is some 7900X3D benchmarks (from Phoronix.com):

As you can see, 7950X3D and 7900X3D have weaker performance than non-3d v-cache CPUs like 7700X for example.

The Dual CCD X3D chips have some tweaks that are required to get the best performance. This is due to only one CCD having the extra V-cache. Since the tweaks seem to be Windows-centric, requiring Windows Game Mode and Xbox Game Bar, this optimization may not be available in Linux?

As an indie/aspiring game dev, I really wish AMD provided a path to support optimal usage of the dual CCD layout for gaming (and game development) on Linux platforms

For pure gaming the 7800X3D seems the better option across windows and Linux, but of course I’d like to ensure my code runs optimally on any and all target systems.

For game dev specifically, the 7950X3D probably makes more sense for the additional cores alone (additional overhead of debugging etc) but the picture is unclear where Linux is concerned
