32-Bit CPU Calculation Benchmarks: Super Pi, wPrime2.0

Super Pi Mod 1.5 Source: SuperPI

SuperPI calculates the number PI to 1 Million digits in this raw number crunching benchmark. The benchmark is fairly diverse and allows the user to change the number of digits of PI that can be calculated from 16 Thousand to 32 Million. The benchmark, which uses 19 iterations in the test, is set 1 Million digits.

Lower calculation times are better. SuperPi is not multi-threaded.

There seems to be a bug when running the test AMD Phenom II X3 720 Black Edition system in DDR2 memory bode, but the DDR3 version worked just fine. Scores here were quite slow, with the Intel E8400 leading the AMD Phenom II X3 720 Black Edition's performance by a significant margin.

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.
