All these CPUs are based on one and the same processor core aka Prescott 2M
The Prescott chip is the same as used in 5XX series, which is a 32-bit processor using the EM64T (emulated 64 bit technology) to pretend to be a 64-bit processor... Basically, just a bunch of extra instructions to mock 64-bit processing.
Either way, Intel's EM64T will never match TRUE 64-bit processing which AMD provides. Unless Intel releases a true 64-bit consumer-based processor some time soon, I see AMD gaining the market even after Intel has dominated it for the past 10 years.
I've had a Pentium since I got rid of my first 486SX/33 back in 1992, and I'm finally swayed into a different processor for obvious reasons.
Why buy Intel when AMD does everything and more, better, for less $$?

Unfortunately, AMD copied Intel in that respect with their "Hyper Transport". However, either way you look at it, that idea was never original.
