Here is an article about the Ryzen 9 7900X3D from one of the Internet's premier Linux Tech sites and forums article about how that processor performs using Linux OS: https://www.phoronix.com/review/amd-ryzen9-7950x3d-linux
Here is the conclusion from that Review article:
Overall the AMD Ryzen 9 7950X3D performed very well on Linux for gaming and workloads where the large L3 cache via AMD 3D V-Cache really paid off. But with the lower TDP than the Ryzen 9 7950X and possibly some issues around optimal task placement between CCDs, for some workloads the Ryzen 9 7950X3D was less impressive. Again, see the nearly 400 benchmark results in full to help evaluate whether the 7950X or 7950X3D is most practical for your needs. If power efficiency is a driving factor, the Ryzen 9 7950X3D easily stands as the champion and also as a compelling processor for Linux gamers.
Stay tuned and hopefully soon will be able to provide Linux benchmarks on the Ryzen 9 7900X3D and especially the Ryzen 7 7800X3D for seeing how the AMD 3D V-Cache is there for not having to worry about frequency vs. cache CCD differences on Linux. As any Linux optimizations for the differing CCDs come about, I'll also be covering it and running more benchmarks on Phoronix. Thanks to AMD for providing the Ryzen 9 7950X3D for this pre-launch-day Linux testing.
A processor generally, in my opinion, is not OS specific and any OS should work with any processor installed.
The exception is if a processor is compatible with Windows 11 or not due to it security requirements.
