Tench, Re: If you haven't noticed, Athlon still generates more heat than the Pentium 4, even though the P4 runs at higher clock speeds and has a larger die size.

If you haven't noticed, Intel specifies average power consumption (TDP) while AMD usually gives maximum power consumption. But if you dig a little bit deeper you'll get the maximum numbers for the P4, too:


Processor         Voltage        Current      Power consumption max (typical)

1.7 GHz P4        1.75V          50.2A        83.6W (64.0W)
1.3 GHz P4        1.75V          39.8A        67.1W (51.6W)
1.3 GHz Athlon    1.75V          39.0A        68.0W (61.0W)


Sources:

developer.intel.com (P4)
amd.com (Athlon)
heise.de (c't)

So even at the same clock-speed (where an Athlon outperforms a P4 by a great margin, even on most optimized code) both processors consume roughly about the same.
