Apparently, Intel's next generation desktop processors do not have AVX-512 support. https://www.anandtech.com/show/16881/a-deep-dive-into-intels-alder-lake-microarchitectures/5 …
I have only recently had the opportunity to deploy on AVX-2, so I don't have a strong opinion about scatter/gather on it. But glancing at the tables, I can't say I know why AVX-512 would be any better than AVX-2:pic.twitter.com/5VCGefUMis

Ah, found what I was looking for. AVX2 has hardware gather but no hardware scatter.
