[Tech ARP] x264 HD Benchmark Version 2.0
 

Simply put, it is a reproducible measure of 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.
