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.

wPrime can test all of the Core i5 750's cores at once. As the entry-level Core i5 model, the Core i5 750 doesn't have HyperThreading, which just keeps it from being able to compete with the likes of the AMD Phenom II X4 965 Black Edition.

Windows 7 show s the same excellent scaling as the Core i5 750's cores are loaded up. The total time is cut neatly into quarters as additional cores take on the processing load.
