WebMay 9, 2016 · Even though current SIMD instruction sets already have 256b vectors, the widest element width is 64b for add. AVX2's widest multiply is 32bit * 32bit => 64bit. AVX512DQ has a 64b * 64b -> 64b (low half) vpmullq, which may show up in Skylake-E (Purley Xeon). AVX512IFMA introduces a 52b * 52b + 64b => 64bit integer FMA.
