32-Bit CPU Calculation Benchmarks: wPrime2.0

wPrime 2.0 Source: WPrime

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.

Lower calculation times are better. wPrime is multi-threaded.

This is where you can really see the effect of multi-core scaling. The $99 AMD Athlon II X4 620 processor starts off as the slowest single-threaded processor, but when all of its cores are put to use it's ~3 seconds behind the Phenom II X4s and ~5 seconds behind the $300 Core i7 920 processor.

Under Windows 7 the AMD Athlon II X4 620 continues to fair well in this mathematical benchmark. While its single core performance can't quite keep up the Intel Core 2 Duo E8400, with all four cores loaded up it can essentially double its performance, to 14 seconds..
