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.	Pentium 4 3.2C	45
2.	Athlon64 3200+	43
3.	AthlonXP 3200+	44
4.	AthlonXP 2500+	53
5.	AthlonXP 2500+ @ 2.21 GHz	47

Super Pi loves bandwidth and high clock speeds that's why the AthlonXP 2500+ does relatively poorly here. I still remember when breaking 60 seconds was an excellent feat!

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.	Pentium 4 3.2C	179
2.	Athlon64 3200+	145
3.	AthlonXP 3200+	144
4.	AthlonXP 2500+	173
5.	AthlonXP 2500+ @ 2.21 GHz	143

POVRay is more of a pure processor benchmark and here we see that while the AthlonXP 2500+ comes in second last at stock, it actually comes in first when overclocked!
