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.

Single threaded performance is not a strong suit of the Phenom II X4 910e , which has had its core clock speed neutered in order to fit into its 65W thermal envelope. With just one 2.6GHz core trying to compete with faster and more compute-efficent processors, the Phenom II X4 910e is only able to place second-last here.

SuperPi also enjoys a very minor increase in speed in Windows 7, despite being a single-threaded benchmark.

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 2.0 is a great multi-threaded benchmark for testing the number crunching capabilites of a processor. It allows us to stress one core, or any number of cores up to the total amount in the processor. The CPUs benchmarked here range from two to four cores, so the most important results to pay attention to are the final block of results - the all threads results.

With all of its threads enabled, the Phenom II X4 910e is able to partially make up for its embarassing SuperPi results. Putting all four of its cores to use results in competitive scores, but its still can't quite beat its less expensive but higher-frequency little cousin, the Athlon II X4 635.

Windows 7 doesn't have much an effect on wPrime scores, this theoretical test won't be affected much by the choice of operating system.
