But are there special vector instructions added in Haswell?
Or is this just general preference for a multi core newish cpu ?
- cbuq 9y agoNot sure if this is their reasoning, but Haswell introduced AVX2 instructions (https://en.wikipedia.org/wiki/Advanced_Vector_Extensions#Advanced_Vector_Extensions_2 https://en.wikipedia.org/wiki/Advanced_Vector_Extensions#Adv...)
- wohlergehen 9y agoAVX2 introduces vectorized Fused-Multiply-Add, for a 2x boost in linear algebra ops.
