Roman5: Actual specs of the WiiU revealed
http://www.eurogamer.net/articles/df-hardware-wii-u-graphics-power-finally-revealed - The Wii U GPU core features 320 stream processors married up with 16 texture mapping units and featuring 8 ROPs.
- The Wii U hardware is based on AMD's RV770 line of processors - essentially the Radeon HD 4xxx cards (from 2008)
- The final GPU is indeed a close match to the 4650/4670, albeit with a deficit in the number of texture-mapping units and a lower clock speed - 550MHz.
With these numbers we can now, categorically, finally rule out any next-gen pretensions for the Wii U bearing in mind the inclusion of just eight ROPs, it's highly unlikely that we'll be seeing any complex 3D titles running at 1080p.
The WiiU is not a next gen console
I admit I don't know much about this kind of stuff but I'd still like to point you to NeoGAF, the guys that were given the picture for analysis from Chipworks which DF analysis comes from.

Been reading some of the comments on your thread and have a few of my own to use as you wish.
1. This GPU is custom.
2. If it was based on ATI/AMD or a Radeon-like design, the chip would carry die marks to reflect that. Everybody has to recognize the licensing. It has none. Only Renesas name which is a former unit of NEC.
3. This chip is fabricated in a 40 nm advanced CMOS process at TSMC and is not low tech
4. For reference sake, the Apple A6 is fabricated in a 32 nm CMOS process and is also designed from scratch. It’s manufacturing costs, in volumes of 100k or more, about $26 - $30 a pop. Over 16 months degrade to about $15 each
a. Wii U only represents like 30M units per annum vs iPhone which is more like 100M units per annum. Put things in perspective.
5. This Wii U GPU costs more than that by about $20-$40 bucks each making it a very expensive piece of kit. Combine that with the IBM CPU and the Flash chip all on the same package and this whole thing is closer to $100 a piece when you add it all up
6. The Wii U main processor package is a very impressive piece of hardware when its said and done.
Trust me on this. It may not have water cooling and heat sinks the size of a brownie, but its one slick piece of silicon. eDRAM is not cheap to make. That is why not everybody does it. Cause its so dam expensive
