Super PI
Super PI Mod 1.5 calculates pi to a specific number of digits after the decimal point. We elected to use 1 million digits (1M). The result is given in the form of the time taken to finish the calculation (in seconds). However, it is a single-threaded benchmark, so it's only useful as an indication of how fast these processors are with older, single-threaded applications.

The D0 stepping was about 1-2% faster than the C0 stepping in this single-threaded test. A very small boost in performance, but it is still an improvement.
