x264 HD Encoding

x264 HD Encoding Benchmark

Simply put, it 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.

This application did fairly well when run on 12 threads, as you can see from the screen shot above. The first pass was only using about half of the processing power, but on the second pass all 12 threads were at ~95% load.

x264 HD Encoding Benchmark Results

Benchmark Results: The x264 HD benchmark is said to be ideal for a benchmark because the application reports fairly accurate compression results for each pass of the video encoding process, and it uses multi-core processors very efficiently. The Intel Core i7 875K does very well here beating all of AMD's high-end desktop processors when it comes to the first pass. That is impressive as the AMD Phenom II X6 1090T has six cores and the Intel Core i7 875K has just four.
