It's bit of a blast from the past but I've recently swapped my AMD 64 3200 + 2.2 GHz for the same spec AMD processor, but that has a lower wattage from 89 Watts to 65 Watts. And my overall power consumption has dropped from 84 to about 65watts. (these were the most amazing CPUs on the planet once!)
I realise I'm going to take one heck of energy consumption hit when I upgrade properly, to a new processor, which I plan to do. Putting aside the low-power AMD processors. Most of the current crop of multicore core processors are around the 130 to 145 wattage overall power draw on idle. The three and four cores obviously a bit higher. I've got these figures by looking at quite a few test reviews. One comparison I would like to see but have not, is the AMD 5050e versus the new AMD Athlon II and Phenom CPUs
It seems ridiculous to have these power requirements when just playing music or having the computer on overnight downloading. I think they should make high-power CPU that has something like an atom integrated into the motherboard or the processor that you could switch to when you are using your computer as a server or doing something that needs minimal computer power. saving money and the planet.
