Are you sure? Last I saw they had dropped XOP and hadn't added any 256-bit registers. Now that I'm searching for this, I see lots of mixed reports: some say it has AVX2, other say it has no AVX2. I can't find any official source that states this definitively.
Edit: Ok I found cpuinfo output here: http://openbenchmarking.org/system/17030...0X/cpuinfo Looks like it does indeed have the AVX2 flag. Now I'm wondering if only certain Ryzen CPUs have AVX2 while others don't, or if the people saying it doesn't have AVX2 are just mistaken?
