Look at the table in the centre, listing instruction set capabilities of Nehalem, Sandy Bridge, Haswell and Knights' Landing. KL shows support for SSE* (presumably meaning SSE1->4.2), AVX, AVX2 and AVX-512.

These things will also come as discrete CPUs. We'll see next year.

I'm sure if jhu commits to building a 100K node supercomputer he can probably command a significant discount!
