Some PIII's have 133MHz bus. Thus if your simulation is memory intensive PIII 500MHz can be faster than Athlon 1GHz. But I am using both PIII's and Athlons and for me Athlons are 30% faster at the same clock speed. I would rather blame some of your hardware. Maybe you have some sophisticated animations? My hints: 1. think carefully of your hardware 2. run tests from: http://fampm201.tu-graz.ac.at/karl/mma.html I did it for Mathematica 3 and Athlon 500MHz had 6.8 while Celeron 580MHz (o'c 466) had 6.1.
