Ryzen OpenCL benchmarks?

Password cracking is an embarrassingly-parallel problem and acceleration comes from parallelism. AVX2 with 256-bit registers enables us to operate on eight 32-bit words or four 64-bit words simultaneously, versus only four 32-bit words or two 64-bit words with SSE2. For most all hash algorithms, a lower-clocked CPU with AVX2 will run circles around a higher-clocked CPU with only SSE2. So yes, AVX2 is critical for a modern password hashing rig, especially now that high-end Intel CPUs can add an additional e.g. 1 GH/s to NTLM.
