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 AMD A6-3650 APU did fairly well in this benchmark and was found to be faster than the Intel Core i3-2105 3.1GHz processor and was in a tie with the Core i3-2120 as it was slower on the first pass, but faster in the second pass.
