Benchmarks: video and audio encoding (x264, x265 and Flac)

By using Staxrip we convert Full HD video to H.264 or H.265. For both we use the commonly used x264 and x265 codes, but for the processors with built-in GPU we also run the tests using the Intel QuickSync and AMD VCE encoders. On top of that we also measure how long it takes to convert an hour worth of uncompressed audio to Flac.

The i7 2600K in the x264 test is about a third faster than the i5 2500K, but that's just enough to catch up to the G4560. The single-threaded Flac test lasts more than 400 seconds on both Sandy Bridges, much longer than on all modern CPUs.
