AMD FX-4100 Quad Core 3.6GHz Bulldozer Processor ReviewTue, Nov 08, 2011 - 12:00 AM
x264 HD Encoding
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 very CPU intensive and it showed that AMD FX-4100 was able to turn in scores of 96 FPS on the first pass and 19 FPS on the second pass. These are respectable scores for a quad-core processor, but are slower than the AMD A8-3850 Llano processor! Shocking since the AMD A8-3850 has a 700MHz slower base clock!
