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. We are using x264 HD v4.0 for this test.
This application did fairly well when run on 4 threads, as you can
see from the screen shot above. The first pass was not using all of the processing power available on the four cores, but on the second pass all 4 threads were at
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 Pentium Processor G620 costs $73.87 shipped and for the price it does fairly well considering it scored 64 FPS on the first pass and 11 FPS on the second pass. For example if you break down the performance to the street price you get ~0.87 FPS per dollar that you spent on the Intel Pentium Processor G620. The Intel Core i7-2600K has by far the best performance of all the processors tested, but it also costs the most at $323.36 shipped. If you check out the performance per dollar you get just ~0.46 FPS per dollar on this processor, which means you get the Intel Pentium G620 offers really good performance for the amount that you are paying.
