There are a handful of x86/x86-64 instructions, including a few fairly common ones, that KNC won’t support. The vectorization and scalar instructions that KNC/KNF introduced are also unique — KNC doesn’t support traditional SIMDs like MMX, SSE, or AVX… yet. That “yet” is important, because it’s virtually guaranteed that Intel will cross-pollinate its instruction sets at some point in the future. The Transactional Synchronization Extensions (TSX) set to debut in Haswell might be extremely useful for Knights Corner’s successor.

而家無SSE2真係幾

KNC 只 support zmm 512-bit registers. mm, xmm, ymm 全部 banq

可以返屋企訓覺
