Python 2.3.2 (#49) pystone test on my Win2k SP4 machine. Note this is a 1.6 ghz Pentium M (Centrino) Pystone(1.1) time for 50000 passes = 1.3762 This machine benchmarks at 36331.9 pystones/second Faster than Anthony's 3Ghz P4. I believe this processor has a very large on-board cache.. I'm not sure how large. It's a Dell Lattitude D800. My point being, I think pystone performance is greatly effected by CPU cache, more so than CPU clock speed.

yes, the pentium M is intel's fastest CPU though they don't like to admit it lest people stop buying P4s. current models have a 1mb L2 cache and an well optimized p3-derived core.

cpu cache size will have an effect on any benchmark. if one python implementation outperforms another because of a better cache foot print thats good thing. cache architecture will only become more important as time goes on.
