x264 HD Encoding

x264 HD 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 v4.0 for this test.

x264 HD Encoding Benchmark

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.

x264 HD Encoding Benchmark Results

Benchmark Results: The x264 HD benchmark showed the Intel Core i7-3770K had very solid passes with 164.5 FPS on pass 1 and 41.7 FPS on pass 2. We are getting up to the performance level of the Intel Core i7-990X processor, which cost more than three times as much as the Core i7-3770K when it came out!
