Developer’s Description

By wPrime Systems
Calculate pi to a specified number of digits up to 32 million.

Super PI is a single threaded benchmark that calculates pi to a specific number of digits. It uses the Gauss-Legendre algorithm and is a Windows port of a program used by Yasumasa Kanada in 1995 to compute pi to 232 digits.

Super PI is a single threaded benchmark ideal for testing pure, single threaded x86 floating point performance and while most of the computing market has shifted towards multithreaded applications and more modern instruction sets, Super PI still remains quite indicative of CPU capability in specific applications such as computer gaming.

Super PI is used by overclocking communities worldwide to test the performance and stability of their computers. If a machine is capable to calculate pi to the 32 millionth place without a mistake, it can be considered to be moderately stable for RAM/CPU. Although not the fastest pi calculator, it remains very popular with hardware overclockers.
