epixoip is correct. It is AVX2 emulation. There is no dedicated AVX2 hardware, the two 128-bit FMACs fuse to carry out AVX2 instructions, so you are looking at half rate AVX2 on Ryzen.
I've got a 1800x sitting on my desk but board has not arrived so I can't run any tests, I did see a benchmark of bcrypt using JTR and the 1800x out performed the 5960x, though i'm not sure whether AVX2 is used there. (see http://www.phoronix.com/scan.php?page=ar...inux&num=4)
Whats interesting about Ryzen is that is has dedicated SHA instructions so that could yield interesting results.
