Palomino cores output tonnes more heat. First hand experience.
I absolutely loved my 1600+ Palomino. Wonderful performer and heat wasn't really so bad. Then I upgraded to a 2600+ Thouroghbred B. The die is so much smaller that it cooked under the copper heatsink. The aftermarket heatsink I tried was even louder and didn't cool much better, so I replaced it with a P4. My machine is now very cool and quiet, but suffers from many performance issues, including studdering and very slow performance in older games than the Athlon.
I would've added another line to the AMD list: they don't cap their cores. Of course, that's changing with Athlon 64. I might very well go back to AMD, after all.
PS - Anybody know about P4 or i865 stability problems? With my Athlons I haven't seen a BSOD in more than a year. Now that I have a P4, I've seen 4 catastrophic crashes in two weeks! I know some apps like Flash Player 6 crash like crazy on the P4, but is there a bigger problem, here? :-?
