Official P4 power dissipation ratings: http://www.intel.com/support/processors/pentium4/thermal.htm Note that these are NOT the maximum power dissipation ratings, only the "average" rating as computed by Intel. This site is not official, but I haven't found a listing on AMD's website, and it's annoying to troll through all the spec sheets to find them. http://www.doerte-richter.de/mulle-78/AMD/amd_term_power.htm
