The craziest thing about Intel's AVX-512 story is that from 2015 through 2020 they were shipping consumer CPUs with die space reserved for the AVX-512 register file, but no actual AVX-512 capability. Then they shipped one short-lived generation of desktop processors and two generations of laptop processors that actually had AVX-512 functionality before disabling it. AMD has already been shipping AVX-512 in their consumer processors for longer than Intel did.
