I'm not under the impression that a 1001MHz chip will outperform a completely different chip running at 1000MHz. But if you design your chip to clock high (and make no mistake, _both_ the Alpha and P4 were designed to clock extremely high) they will outperform chips that _aren't_ designed to clock high, like the POWER3 and the R12000. Who knows how fast the P4 would have been if it ran the Alpha ISA instead of x86... -Tom
