Basiclly you then get a PPU in the cell. That PPU is 11.3mm^2. Forget that triple-core with eDram CPU that is only 30mm^2 in size. Not doable unless it is a core much simpler than the ones in the PS3/X360. Again I think the picture of the WiiU board mislabels the eDram (or some other component like the rumoured sound DSP chip or the ARM coprocessor) as "CPU" and the CPU/GPU/(eDram/ARM/Whatever) combo is in the chip carrier labeled "GPU". The images show that all the visible address/data bus lines go to this chip carrier, and not to the small chip.
