Pete: How could merely doubling the cache and doing a few little things make it (Prescott) so much newer?

Any (positive) change Intel makes to their processor core can be used to great advantage, because they have both the clout and the resources to affect changes in benchmarks. Anything Intel has that AMD doesn't will be used - you can count on it. Whether this be larger cache, greater bandwidth, special instructions… anything that *can* be used, *will* be used.

Oh, and don't think there aren't a lot of improvements to be made to the P4 core. There are still plenty of cases where it is decode bound and HyperThreading can still be greatly improved as well. Doubling the trace cache and the decode resources (and possibly L1 data cache) would increase performance in a wide range of applications with minimal increase in die space. Not at all unlikely for a reworked core at 90nm, IMHO.
