Great 3 page review with LOTS of benchmarks. So, keep in mind that the new Ryzen is actually 8 core with 16 threads, unlike Vishara and Bulldozer which were both 8 core/8 threads.
From what I see, where it matters the Ryzen is pretty bad ass. I especially like the Handbreak results. It's pretty awesome.
But, on my 5820k if I OC to 4GHz, it saves about 12 seconds on every minute it encodes a x264 video file. (MKV to MP4)
In short that's a 2 minute savings on a normal 10 minute encode. Enjoy and I am happy to see AMD kick it up a notch.
