Jeff, technical stuff following:

<If you think the Pentium III is superpiplined then I guess you haven't been exposed to much CPU design.>

Jeff, what's your definition of "superpipelined"? Hennessy and Patterson define superpipelining as extending the length of the pipeline in order to make each pipeline stage less complex. This allows for higher clock speeds.

All P6 cores, including Celeron and Pentium III, have a 12-14 stage pipeline. The Athlon has a 10 stage pipeline. So technically, in terms of number of pipeline stages alone, the P6 is even more superpipelined than Athlon.

(On the other hand, I take back what I said about P5 and K6 being superpipelined according to Hennessy and Patterson's definition above. Both only have a 5 or 6-stage pipeline.)
