Re: IPC gains P2 vs Pentium The fact is that IPC of P2 is SMALLER than Pentium Classic, by as much as 30% if I remember some charts correctly. However, the non-blocking backside L2 cache and pipelined FSB of PentiumPro/P-II/III have tremendous effect on the CPU stall time - reducing it by a factor of 5, as I remember those performance charts (and the L2 speed does not matter much at all). The Pentium Classic (and every other compatible processor) beats P-II in performance on application benchmarks if below 200MHz, but "scales better" if the core frequency is higher. Which is the proof of the said statement about IPC. Regards, - Ali
