How do you get that, G? Two revs behind?

The P3/Athlon were the same revision core.

P4 Stuffed up big time. Athlon XP.

P4-D is back to the P3 arch. Athlon on Skt939 (AMD 1 ahead)

Core Duo/Athlon on the AM socket (AMD remains 1 ahead)

Core2/Athlon on the AM2 socket (AMD remains 1 ahead)

If you want to go just by the names, then Intel only have the P3 and failed P4 and AMD have the Athlon. Intel one ahead. The core is really the result of the Intel engineers in Israel being left along by the marketing doofuses and were finally able to find out how to increase clock rate on the P3 arch while the marketing doofus was trying to win the gigahertz war by pushing the unready P4 tech. The core systems were when the marketing idiots finally realised that they couldn't get the P4 or itanium to fly and let the rest of intel progress the P3 arch.

NOTE: When it comes to power consumption, Intel use maximum realisable power. I.e. when you're maxing your CPU under system loads, what power is needed. AMD go on maximum theoretical power. I.e. if everything is being clocked at 100% (which isn't possible) how much power will it use.

That makes most of the difference between TDP rates of the CPUs disappear. Add in that the AMD chips don't have the memory controller (which can add 10W all on its lonesome), the difference between the two chips is down in the "well, it depends on how you use it" range.
