> A single modern CPU core turboing at ~5Ghz is going to be significantly faster than a 20 year old cpu overclocked to ~4.5Ghz. Is it actually going to be faster than a P4 running at the speeds that they can clock up to, especially if we're talking about sustained performance rather than a brief turbo? Obviously "non-vectorisable integer computation that never stalls a 70 cycle pipeline" is not the only thing that matters for software performance, but it's worth comparing.
