Wbmw:

Yet with that 1 watt of power difference Yonah will clock 566MHz faster (at first), and the roadmaps eventually have 2.33GHz showing up sometime in the second half of next year (presumably early in H2, since Merom will be launching later in the quarter). That's 733MHz faster than what AMD is promising at 90nm (assuming they can actually deliver).

Its 6-7W difference (and it could be higher given the differences in conditions) when you include the memory controller in the NB. Adding back that power in higher clock, it likely will get to 2.2GHz, faster than Yonah with 64 bit and much faster FP. In 90nm, no less.

Measurements will confirm how close the power dissipation of Yonah is relative to DC K8. My guess is that once reality sets in, you will realize that Intel will have a huge power advantage in the mobile segment next year.

I think you will see Yonah as not being as good as hoped wrt K8.

It's also worth noting that the Intel system lasted 25% longer in the Office application battery life test, which is important to many business users. Wattage wise, the Intel system dissipated 22W system power, while the AMD system dissipated 27W. Now, the Intel system demonstrates 5W better power dissipation for business tasks.

I think what that shows is that the chipset is still an advantage for Intel. Likely the Turion's LCD needs more power to get the same brightness (this was shown in a previous page). So the performance difference is even higher. As to the graphics speed, you better look at the setup on previous pages. They deliberately overclocked the Turion's GPU to the same clocks as Dothan's GPU.

So you have one set of data on the X2, but the same measurement methodology was not used for Dothan, so you do not have an apples to apples comparison, just more wild speculation.

When 2Ghz Dothan is measured using the same setup, it gets higher than the listed 21.5W TDP at 25.4W. The 2.13GHz Dothan was not tested. But if it gets the same ratio as the 2GHz, it would get 31.9W. The only wild speculation is how Yonah would do performance and power wise.
