Simply put, the x264 HD Benchmark is a reproducible measure of how fast your machine can
encode a short HD-quality video clip into a high quality x264 video
file. It’s nice because everyone running it will use the same video clip
and software. The video encoder (x264.exe) reports a fairly accurate
internal benchmark (in frames per second) for each pass of the video
encode and it also uses multi-core processors very efficiently. All
these factors make this an ideal benchmark to compare different
processors and systems to each other. We are using x264 HD v4.0 for this test.
This application did fairly well when run on 12 threads, as you can
see from the screen shot above. The first pass was not using all of the processing power available on the cores, but on the second pass all 12 threads were at
Benchmark Results: It’s no surprise that once overclocked the Intel Core i7 3770k is significantly faster than running at default settings. The first pass was more than 40 frames per second faster than running at default speeds, the second pass was nearly 11 frames per second faster or 26.9% faster. Despite running at the same 4.7GHz clock speed the Intel Core i7 3770K ‘Ivy Bridge’ Processor was able to out perform the second generation Intel Core i7 2600K by ~3.6 frames per second on the processor intensive second pass.
