AMD FX-8150 Processor Review – Bulldozer Arrives

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~98% load.

Benchmark Results:
The x264 HD benchmark is very CPU intensive and it showed that AMD FX-8150 doesn’t do that hot on the first pass, but it does do very good on the second pass, which is the most time consuming. On the second pass the AMD FX-8150 was able to beat out the Intel Core i7-2600K processor and lost to only the Intel Core i7-990X.
