Radeon HD 4870 RV770XT
Radeon HD 4850 RV770PRO
Radeon HD 4830 RV770LE
Radeon HD 4730 RV770CE
Now if the card is anything except 4730 and 4830, then its a power chipset!! Also we have to consider how many stream processing units Nintendo cut off from this chipset! The basic we can get from this chipset is 320 SPU's, if its 320 for low cost, its much more powerful than xbox360 and ps3, but it will not be powerful enough for xbox720 - ps4 systems. If its 400, then it will be powerful enough even for the next gen consoles! Here is the foggy part of the story!!
There is no specific information about the GPU, they speak about r700 4xxx series card, but most of the net speaks about r770 and nothing else. If someone can get at least how many SPU the wii U gpu got, it would be perfect to know!! Because from this little detail, we will know, how much powerful wii U is!!! The cpu is pointless, all system will come, with about the same cpu power (Even if ps4 or 720 have better cpu, this will not effect our games and compete between them) because games do not require better cpu than that (core speed yes).. The GPU and core speed matters. So we must focus, to find out, how many SPU wii U got and video ram (gddr3? or gddr5)..!! nothing else! All the rest are pointless, because its really powerfull in all other aspects..
this are the cards that use r700 chipset (this are the pc cards, when a console company gets one of this cards, they tweak it, they cut off SPU, they add/remove features for low cost and low heat/power consuption).

If anybody knows how much Mhz the gpu speed is, then we may find which card is it.. If its more than 500mhz (gpu core speed), then its a 4870 @ 7xxmhz (tweaked), if its less than 550 or 500 mhz.. then the graphic card is 4850 and lower.. Alao many leaks speak about a 40nm GPU, and this is a faulty information, as all 4xxx series are 55nm (except if wii U got 5xxx series and they hide it!!!)
