At this point, I am strongly doubting that there have been enhancements made to the instruction pipe. I believe Jerry is currently happy with the size of his pipe, and doesn't need to artificially enlarge it to please the wome .. er .. the consumers. <g> I would have liked just a teensy change in the direction of pipeline lengthening, but as it is the process boost will probably help enough for the time being for AMD to compete. I should note that it appears as if AMD's ramping problems are power/heat related, not speed path related (as was the problem with the PIII at >1.00GHz), so the particular process changes they are making should be sufficient for the time being. Incidentally.... I personally believe that the Athlon at 1.20GHz is generally similar in speed or faster than the Pentium 4 at 1.50GHz. If you take this as a certainty in this perhaps not so hypothetical scenario, how would you think 1.50GHz and 1.60GHz Athlons would perform against the expected-at-Q3 2.00GHz Pentium 4? I'm asking because there are differences in scaling which should be noted. Would the higher memory bandwidth of the i850 allow the Pentium 4 to scale better as frequency increases, or would the lower start frequencies and greater execution resources allow the Athlon to scale better? Mind you, for this intellectual exercise I am pretending that the Athlon goes in the way Anand suggests, with the Mustang core not having any per-clock performance improvements. Just curious. :)     -JC
