Using Intel's datasheets and AMD's methodologies to create an apples to apples comparison, I get just under 40W TDPmax for the 2.13GHz Pentium M 770. And just under 8.9W for the FSB, DDR and hub portions of the 855PM from its datasheet. If you want us to use TDPtyp from Intel's methodologies, the TDP for K8Burn is 30.4W for the 2.4GHz Venice that has a 67.5W TDPmax from AMD. Intel's TDP(typ) doesn't include a "power virus" like K8burn when measuring power usages, so we can take that as a loose upper bound.

So if TDPtyp is 45% of TDPmax for Venice (30.4W/67.5W), then a 35W TDPmax Turion has a 15.75W TDPtyp and a 25W TDPmax Turion has a 11.25W TDPtyp. Dothan 2.13GHz has a TDPtyp which is 67% of the 40W TDPmax, than applying the same for Turions gets us to 23.62W/16.88W for the 35W/25W TDPmax. Either way, Dothan is more power hungry than Turion when the same methods are used.

But the hardware isn't the same. That graph doesn't take into account many of the enhanced options on the Asus A8V (939) not present on the DFI 855GME. The 855 has 2 fewer DIMM slots, 2 fewer SATA ports, 1 less IDE port, 6 fewer sound channels, 1/10th the Ethernet speed, dual channel PC3200 vs single channel PC2700, no firewire and 4 less USB ports. Add in cards like a SB Audigy, a RAID IDE card with a DDR cache, a Gb Ethernet card and a firewire card and that system may go beyond that 44W under load.

As to the performance, it overclocks the AGP port by 20%. Do the same for the AMD systems and The Dothan will be further behind the A64s.

If they would measure direct to CPU power ala Lost Circuits, then you could remove all of that (well not the dual PC3200).
