Testing Different Memory Speeds on AMD’s A8-3850 Llano APU

x264 HD Encoding

x264 HD Encoding Benchmark

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.

x264 HD Encoding Benchmark

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.

x264 HD Encoding Benchmark Results

Benchmark Results:
Running the x264 HD benchmark showed that running an 1866MHz memory kit with an AMD A-Series APU means you’ll get roughly 4% better performance than a system running 1333MHz memory. We are talking small differences here between all three memory speeds, but the results are measurable and repeatable.
