OK, thanks all for testing this. The software is optimized for multicore but the algorithm is not that complex and may not reveal 100% accurate the differences between different CPU's.
Having this experience and this goal, I developed a new benchmark, witch use a far more complex multithreaded algorithm. Multi Core PI.
The old benchmark Multi Core Prime is no longer in development. I hope you will find this benchmark more useful and will reveal more accurate performance differences between platforms.
Multi Core PI calculates PI decimals using Bailey?Borwein?Plouffe formula. The benchmark is using a multithreaded algorithm written in C++ and provide excellent parallelism. Multi Core PI is written in Visual C++ using MFC and Win32API.
