Scott, I am not arguing with you, but based on the numbers and what you said, this latest new generation cpu from IBM is not much faster, throughput wise, then what has been used for the last 2 years. That cant be true. Only IBM knows the answer. The news that there will be no more hardware announcements in 2002 was very disappointing.

I can't remember all the technical details but basically two different processors can do the same amount of work but have widely differing processor speeds depending on their architecture, I think it relates to how deep the pipelines are. With the Power4 processor IBM has changed the architecture and now the processor speed appears more in line with processors from Intel. The older processor's architecture made them appear to be much slower than an Intel processor but they were doing much more work per MHz. I would have to refer to that section in the book to get a better description of how this works. Scott Mildenberger
