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.

As a single-threaded bencmark, Super Pi ignores three of the four cores of the Core i5 750, but the Core i5 750 compensates for this by enabling turbo boost mode, which improves scores considerably.

Scores in Windows 7 are marginally slower than they were in Vista, but not so much to change which processors finish first.
