AMD Brazos Platform Benchmarked – Zacate E-350 1.6GHz APUTue, Nov 16, 2010 - 12:00 AM
wPrime 32M & x264 HD Encoding
wPrime uses 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.
wPrime is also a multi-threaded synthetic benchmark used to time how
long it takes to calculate the square-root of a number. We ran the 32M test.
Benchmark Results: The AMD Brazos notebook platform does fairly well in wPrime and is just slightly slower than the ASUS Eee PC 1201N that uses an Intel Dual Core Atom N330 processor at 1.60GHz. The AMD E-350 also operates at 1.60GHz, but was slightly slower as you can see from the chart above.
The x264 HD benchmark is a reproducible measure of 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.
Benchmark Results: The x264
HD benchmark is said to be ideal for a benchmark because the application
reports fairly accurate compression results for each pass of the video
encoding process, and it uses multi-core processors very efficiently.
The AMD Zacate E-350 APU does very well in this benchmark and was faster than the Intel Atom N330 and Core 2 Solo SU3500 in this encoding performance test.
