40% of 50 Watts is 20 Watts. The 5570 is rated at 39. By your logic that means it can only be twice as powerful as the 2600 XT. Yet it delivers about 4 times the power of the 2600 XT. Newer tech = faster hardware.

Die size difference =! power consumption difference. There are other factors as more advanced transistors technologies as HKMG, for example. The difference is that we're talking here of chips made in the same process, there is not foundry advantage.

I know. In fact, halfing the die size rarely results in being able to deliver twice the power with the same tech.

As for the chips. The Wii U gpu will be based on an entirely different architecture than the Xenos or RSX. That's why I keep saying it's perfectly capable to deliver 3 or 4 times the power of the 360 or PS3 gpu. Just as the 5570 is perfectly capable of outperforming the 2600 XT even if it had the same maufacturing proces.

Using much more transistors and much more power if both were made on the same node. That's is the difference. 5570 use 627 million transistors. 2600 XT use 390 millions. That's why.
