Max, thanks for the comparison Athlon numbers. It's pretty clear that P4 is an unperformer on non-bandwith dependent and non-SSE applications. Andreas

P4 scales horribly - thanks to Max for the excellent benchmark comparison. I noticed how little gain the P4 gets when going from 1.4 to 1.5 GHz. Although you might expect this from disk-bound benchmarks like Sysmark, I suspect that memory latency is a big factor as GHz goes higher, because Quake 3 only gets 40% of the theoretical improvement based on clock speed. In the table below, I define the scalability index as the percentage of the theoretical increase actually realized as clock speed is raised from 1.4 to 1.5. (7.14%) In other words, if a benchmark runs 3.57% faster, there would be a 50% entry at that benchmark.
