Sandpile.org refreshed their CPUID page - it is a goldmine, e.g. the abandoned #AVX512 levels, MIC projects, etc.:

#AVX512QVNNI #AVX512DFMA #AVX512BITALG2 #KnightsBridge #KnightsPeak #KnightsCorner
Today I learned: At least 3 #AVX512 levels were planned, but they never released:
#AVX512QVNNI - byte form of 4VNNIW, it would extinct with KNM/MIC;
#AVX512DFMA - VDF[,n]MADD[P,S][S,D] - I have no idea what the difference between FMA & DFMA;
#AVX512BITALG2 - this is the most interesting for me;
1/3
