- zucker42 5y agoAlder lake's AVX-512 comes with a significant asterisk. It's only in the P-cores (so can only be turned on if you disable the E-cores), isn't officially supported, and can't be turned on in some motherboards IIRC. We should be seeing better AVX-512 support with CPUs in the coming years though.
- einpoklum 5y agoAccording to that link, Zen 4 will only have a very limited kind of AVX-512 instructions, for working with half-precision floats. It won't even have the base AVX-512 instructions (the F set).
- th3typh00n 5y agoThat Wikipedia article is incomplete, Zen 4 will be able to run all AVX-512 code that Ice Lake can run.
