AMD has phony AVX-512.

"Zen 5 revamps AVX-512 implementation
The biggest IPC gains were seen in workloads that used AMD's AVX-512 vector extensions, which have been reworked this generation to feature a full 512-bit data path as opposed to the "double-pumped" 256-bit approach we saw in Zen 4 in 2022."
Ever heard of a Pyrrhic victory?  The hours you burned writing this shit post and futzing with Gentoo and looking up AVX-512 on AMD will NEVER be recouped by the few seconds you save with it running your shit-code on your low-end Xeon W, which is bested in every way possible by cheaper and cooler and faster AMD chips.
I stuck with only Intel from 1986 to 2022 (36 years), but my next few chips will definitely be AMD.
I don't much trust Intel any more, based on their half-ass response to the widespread instabilities in their 13th and 14th gen chips.
