That's not the way I remember it. Unless I'm seriously mistaken, the Athlon 64's thoroughly trounced the P4's and PD's in every way.
Again, the Athlon 64 was a very notable exception to this. With it, AMD was the first to introduce a 64-bit architecture (well, unless you count the failboat that was Itanium) and the first to integrate the memory controller into the CPU (something that it took Intel until the first-gen i-series to do).
Interesting that the last time AMD trounced Intel on the performance field was also the last time that they did a complete architecture redesign and the last time they introduced major industry innovations...and also the last major chip release before they acquired ATI (a move that I don't think they have yet fully recovered from financially). Coincidence? I think not. It does stand to reason that Intel more often pioneers major innovations though...their net income was more than 24 times AMD's last year...hell, their net income was more than twice AMD's total assets that year... o_O
