# Noteworthy CPU Features
SSE 128-bit vector instructions (e.g. addps http://www.felixcloutier.com/x86/ADDPS.html)
SSE4.1 Makes SSE good
SSE4.2 Makes SSE do strings and CRC32
AVX Makes SSE 256-bit (e.g. vaddps)
AVX2 Adds features to AVX
AVX-512 Makes SSE 512-bit
SHA Makes SSE do SHA1 and SHA256
FMA Fused multiply–add
CLMUL Carry-less multiplication https://goo.gl/ritKJX
TSX Transactional memory instructions for threads http://www.intel.com/software/tsx
