AMD has released an updated Athlon 64 Processor Power and Thermal Data Sheet that details the recently-released Athlon 64 FX-55 and 90-nanometer 3000+, 3200+, and 3500+. The new 90-nano chips carry a Thermal Design Power (TDP) of only 67W?22W less than their 130-nano counterparts. With Cool'n'Quiet throttling the 90-nano chips at idle, TDP drops to as low as 20W, but that's only a couple of watts lower than a fully throttled 130-nano chip.
