AMD's upcoming Agena FX and Barcelona native quad core CPU's will consume less than 95 Watts.   We all expected more from this native quad core on 65 nanometre but I guess AMD pulled some kind of miracle.

We are talking about the desktop part but Barcelona should not be much different. A source close to AMD also claims that despite the power efficiency the CPU should be 40 percent faster but it is not clear from what.

It looks that a single core from this device would need less than 24 Watts and at some crazy speeds this is more than good result.  

Agena FX and other desktop parts comes in second part 2007.
