Intel Pentium G850 Sandy Bridge 2.9GHz CPU Review

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 the Intel Pentium G850 was right about 11% faster than the Intel Pentium G620 and 28% slower than the Intel Core i3-2105 processor. If you do a ton of video editing the extra threads that are made available with Intel Hyper-Threading on the Intel Core i3 series for example are well worth the extra money as the performance difference is rather large and it will save you tons of times if this is a task that you often do.
