Tim and BMW, I think you both of you are playing around with numbers.

P4's pipeline is MORE than twice the length of P3's. Obviously if you lengthen the pipeline, you're not necessarily going to get the same proportion of clock speed increase because of the overhead.

As for Motorola, I suspect much of their clock speed increase came not only from the lengthening of the pipeline, but by plain old better design and balancing of the pipeline stages. It's the same way Athlon is able to run faster than a Pentium III, even though Athlon's 10-stage pipeline is slightly shorter than Pentium III's 12-14 stage pipeline.
