Can you explain how is this useful? Does it do H160(pubKey)?

This is my fault. It only outputs public keys(what I asked for).  Smiley

And this helps with what? I see things related to AVX2 and stuff, wasn't this useful for hashing?

If you only want public keys, for whatever reason, there are much faster options than that.

on CPU?

Yes. Maybe I'm like a broken record, but carry-free 5x52 is much faster than 4x64 arithmetic, on CPUs. And it's parallelized away by the compiler automatically. At least by clang.
