How thoughtful of you to quote me then misrepresent my statements. If the XP2800+ is AMD's top chip then it should be compared to the 3.06MHz P4, not the 2.8GHz P4. The XP2600+ and XP2700+ are the second tier of AMD, both running at 68W - the same level as the 2.8GHz P4.
Now you are trying to compare heat ouput by where the CPU is in the company's pecking order (second tier, third tier)? LOL, that is even more absurd. To have a FAIR comparison, you compare a 2.8ghz P4 to AMD's 'comparable' CPU (at least in PR rating), which is the 2800+. AMD doesn't have anything to compare to the 3.06 ghz P4 right now so lets get it out of the picture.
2800+ = 74w
2.8ghz P4 = 68w.
Now who puts out more heat?
If a 2.25ghz 0.13 micron AMD CPU puts out 74w, just imagine how hot it would be if clocked at 2.8ghz. AMD either needs to improve their manufacturing process or lower the voltages of their CPU's.
Please don't make this a 'gray' area kind of argument. Compare the latest CPU's with the latest manufacturing process from each company. 0.13 micron compared to 0.13micron CPU's ( and 0.18micron to 0.18micron CPU's). In order to make a fair comparison, compare CPU's by their ACTUAL clock speed. Even compare the actual clock speed of the P4 to the corresponding PR rating of AMD CPU's.
Now tell me, which CPU's put out more heat?
