Just checked how much that AMD 4850e CPU drains under various conditions. There are *huge* differences. I checked whole power consumption of the machine. I don't know what "at wall" means. Did you measure the power consumption of the cpu alone or does "at wall" mean the same as I did? Here are the figures, considering this is for the whole machine I think it's quite good. idle: 1000 MHz: 76W 2500 MHz: 98W 1 core under load: 110W 2 core under load: 120W So, that's not just the processor, it's the whole machine. It takes into account the powerdrain from the processor plus (probably) faster fans plus any other drain from memory/chipset that may be higher underload.
