Cryptography, Raytracing, KribiBench
A mixed bag of results. Excellent in KribiBench, which is a 3D rendering engine that's run completely in software. CPU architecture and memory bandwidth play the largest part in determining performance, and the Pentium 4 is perfect for this kind of application. Raytracing, on the other hand, is better handled by Pentium M and Athlon 64 CPUs.
