You are leaving out a few key facts here. For example, the WiiU uses an average of 40W according to Nintendo. That translates into a clock rate for the CPU in the 2.2-2.4GHz region. There are other hints like the fact that some (launch) software is NOT running at 1080p, indicating some CPU starvation. So CPU wise, the performance of the WiiU would only be around 60-80% of a PS3/XBox. However, the heavily modified GPU (I don't think there is any similarity left to the standard ATI 4xxx GPU) makes good for that so WiiUperformance (Whichever way you define "performance")  is around 130% of the PS3/XBox as I explained in a precious post. Also my previous estimates for PS4/XBoxNext are still reasonable, based on what we know at this time (and there are enough hints for the XBoxNext). SImply forget that 4-? times more powerful (again the meaning of "power" should actually be defined).

Are you using just clock rates as the means to surmise performance against the Cell and Xenon?

Since we don't know what really is inside a WiiU, all we can estimate is based on known facts like 40W power, 45nm design technology, three cores - and compare this with known processors. There is no magic involved here that would suddenly make a 45nm design processor "run like hell" with (probably less) than 20W to burn.

 

 

Weird. Just installed Win8 on my newly assembled PC and I can no longer logout on the site...

I think you just forgot to mention it: We also now the size of the chips (how much of the GPU one exactly is due to edram remains to be seen), and together with the design technology we can guesstimate the number of transistors (or compare it with chipsize/(design technology)^2-values of other CPUs directly). Gives a better estimate than just basing it on power and design technology (a really big chip could run at a really low voltage and clockrate using less power, while of course not being cost efficient).

My notebook also uses Windows 8 since a few days (I ran out oft W7 licenses since MSDNAA changed there rules while becoming Dreamspark). I've to check if I've the same problem. edit: no, works fine for me.
