Known mainly for its DVD re-encoding prowess, our test uses the Handbrake command line interface on a full DVD rip to gauge CPU performance.
x264 HD Benchmark
The popular x264 benchmark available from graysky does a two-pass H.264 encode on 1080p video. The first pass appears to be more clock-sensitive while the second pass is more heavily threaded.
Kaveri has a strong showing in our x264 encoding test and is able to outperform the previous generation parts from the Richland family with ease, 29% faster in the second pass result for example. I find it very impressive that AMD's new 45 watt part can compete with its own 100 watt Trinity APU.
