Ali, I am having hard time to believe that the pipeline can be made much deeper without strongly degrading the overall CPU performance on current workloads. At the same time I have hard time to believe that the logic complexity can be significantly reduced for all these prefetches, predecodes, decodes, more decodes, and dispatching results to multiple execution units. I disagree. The only time that a deep pipe can hurt performance is on mispredicted branches. As a general rule, it is easier to implement a deep pipe than a shallow one, because the amount of work done per stage is proportionately less. I expect that Willamette performance will be quite good. Scumbria
