The least interesting part about AVX-512 is the 512 bits vector width
I am a happy owner of a Tigerlake (Intel 11th Gen) Framework laptop. I've considered upgrading to a 12th or 13th Gen motherboard, and while I have no doubt they'd be great for me as a Gentoo developer with the greatly increased core counts, my hesitation is that the new CPUs have AVX-512 disabled.<p>Maybe this doesn't matter, almost certainly wouldn't for most people, but I'm compiling the whole system myself so the compiler at least has the freedom to use AVX-512 wherever it pleases. Does anyone know if AVX-512 actually makes a difference in workloads that aren't specifically tuned for it?<p>My guess is that given news like <a href="https://www.phoronix.com/news/GCC-AVX-512-Fully-Masked-Vector" rel="nofollow noreferrer">https://www.phoronix.com/news/GCC-AVX-512-Fully-Masked-Vecto...</a> that compilers basically don't do anything interesting with AVX-512 without hand-written code.
