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 2 GHz	299 sec
2.	AthlonXP 2000+	189 sec
3.	AthlonXP 2100+	183 sec
4.	AthlonXP 2100+ (oc'ed)	171 sec

With no special instructions for either CPU, the AthlonXP's powerful FPU simply destroy's the Pentium 4 in POVray. Knowing AMD's history with number crunching this is not very surprising to see.

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 2 GHz	95 sec
2.	AthlonXP 2000+	75 sec
3.	AthlonXP 2100+	66 sec
4.	AthlonXP 2100+ (oc'ed)	60 sec

Like POVRay, SuperPI is a pure FPU benchmark and again the AthlonXP does very well here.

3DMark2000 Ver 1.1	Source: MadOnion

3DMark2000 is still a popular benchmarks for evaluating 3D performance even though it is getting a bit dated. 3DMark2000 continues to provide benchmark results that gage DirectX7 performance and hardware transformation and lighting that older games still use. Version 1.1 ensures more reliable functionality with hardware and operating systems that were released after the launch of 3DMark2000 in December 1999. Higher numbers denote better performance.

3DMark 2000 v1.1 Benchmark Results
	Processor	3DMarks	Ranking
1.	Pentium 4 2 GHz	9221
2.	AthlonXP 2000+	11114
3.	AthlonXP 2100+	11816
4.	AthlonXP 2100+ (oc'ed)	12440

Using a GeForce3 Ti500, 3DMark2000 becomes more of a CPU benchmark then anything else, and here the AthlonXP stomps all over the P4. In 3DMark2000 the driver difference between the 21.83 and 22.80's should be less than 1%-3%.
