X264 HD Video Encoding Benchmark

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 8 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 X264 HD Video encoding benchmark shows that the GIGABYTE X99-UD4P and the ASUS X99-Deluxe are in just about a dead heat. The GIGABYTE X99-UD4P was able to average 128.48 frames per second during the first pass and 28.23 frames per second during the second, much more processor intensive pass. The ASUS X99-Deluxe was a hair slower during the first pass with an average of 128.41 frames per second, and a hair faster during the second pass with an average of 28.29 frames per second.
