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 numbers denote faster calculation times (seconds), and hence, better performance.

Super PI (1 Million digits) Benchmark Results (Lower is better)
	Processor	Seconds	Ranking
1.	AthlonXP 3000+ 166/333	48
2.	AthlonXP 3000+ 200/400	44

Honestly this was the benchmark that surprised me the most. I always thought Super Pi was mainly CPU limited but here we get a very healthy 4 second decrease in time thanks to the faster FSB!

The Persistence of Vision Ray Tracer (POV-Ray) is an all round excellent package, but there are two things that particularly make it stand out above the rest of the crowd. Firstly, it's free, and secondly, the source is distributed so you can compile it on virtually any platform.

Lower numbers denote faster calculation times (seconds), and hence, better performance.

POVRay Benchmark Results (lower is better)
	Processor	Seconds	Ranking
1.	AthlonXP 3000+ 166/333	145
2.	AthlonXP 3000+ 200/400	144

POV-Ray cannot really differentiate between the processor bus speeds. POV-Ray is a pure FPU benchmark and because the CPU speeds are approximately the same, performance is as well.
