3DPM Peak AVX test

8-core RKL 4.6 GHz AVX512 290 W โžก 32845 pts

64-core Zen2 3.0 GHz AVX2 280 W โžก 28761 pts

I challenge you to provide the full source code. According to your description, AVX512 path was hand-optimized by an Intel employee. But not the AVX2 path. Sounds fishy at best ๐ŸŸ๐ŸŸ๐ŸŸ
Where did I say that the AVX2 path isn't optimized?

"we also have a fully optimized AVX2/AVX512 version, which uses intrinsics to get the best performance out of the software. This was done by a former Intel AVX-512 engineer who now works elsewhere" https://anandtech.com/show/16495/intel-rocket-lake-14nm-review-11900k-11700k-11600k/7โ€ฆ

Implies strong possibility of bias

That literally says AVX2/AVX512 was optimized by an AVX512 engineer. Both versions.

AMD has had full code for 3yrs, and when asked if they had revisions, they said no, and we're fine with me continuing to use the test.

If AMD is OK with it, what's got a bee up your bonnet?
