x264 HD Encoding & WPrime
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 the AMD FX-4100 Bulldozer processor averaged 94 FPS first and 19 FPS on the second pass.
wPrime is a leading multithreaded benchmark for x86 processors that
tests your processor performance by calculating square roots with a
recursive call of Newton’s method for estimating functions, with
f(x)=x2-k, where k is the number we’re sqrting, until Sgn(f(x)/f’(x))
does not equal that of the previous iteration, starting with an
estimation of k/2. It then uses an iterative calling of the estimation
method a set amount of times to increase the accuracy of the results. It
then confirms that n(k)2=k to ensure the calculation was correct. It
repeats this for all numbers from 1 to the requested maximum.
The CyberPower Gamer Ultra 2098 uses the AMD FX-4100 ‘Bulldozer’ processor and we found 32M test completed in 19.921 seconds and the 1024M test completed in 615.886 seconds.
