You Anandtech is comparing the "typical" wattage for the P4 to the "maximum" wattage for the AthlonXP. Now, tell me anandtech isn't biased. Here's proof he is doing it, too. This is out of the Intel datasheet! "2. The numbers in this column reflect Intel’s recommended design point and are not indicative of the maximum power the processor can dissipate under worst case conditions. For more details refer to the Intel® Pentium® 4 Processor in the 478-Pin Package Thermal Design Guidelines" Now, as you can see from http://users.erols.com/chare/elec.htm it shows the maximum wattage is 33.3% over the typical wattage for the other P4's. Now, if you take the current wattage multiply it by 1.333 you get the maximum wattage. Not you can compare it to the AthlonXP. Here are the REAL wattages. Listed by highest to lowest watts... P4-3.06GHz - 109.06 watts P4-2.8GHz - 91.18 watts P4-2.66GHz - 88.11 watts P4-2.53GHz - 81.98 watts P4-2.4GHz - 79.71 watts XP-2800+ - 74.3 watts XP-2700+ - 68.3 watts XP-2600+ - 68.3 watts XP-2400+ - 68.3 watts XP-2200+ - 62.8 watts As you can see the P4's are much hotter. AMD chips only feel hotter because for some reason they feel the need to ship them with horrible heatsinks. Put on any large copper heatsink and you won't even come close to having a problem.
