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 v5.0.1 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 ~95% load.
Benchmark Results: The GIGABYTE Z87X-OC Force was the fastest of all our our motherboards in the X264 HD Video Encoding benchmark. The first pass which isn’t the most processor intensive hit an average frame render speed of 85.55 frames per second and was .3 frames per second faster then the ASUS Republic of Gamers Maximus VI Hero. The second pass which is considerably more processor intensive averaged 17.41 frames per second which is once again the fastest performance out of the bunch, albeit by .08 frames per second.
