I didn't know about the different APU, thought that it was just that Microsoft was using an inferior version of the same base generation APU, like say a 7950 vs a 7970 graphics card.
Do you have a link as quite interested to read up on that, is it a difference size manufacturing process or something as a less powerful APU should surely be smaller if smae manufacturing process?
(Sorry I'm not that clued up these days on the technical stuff with the next gen consoles).

The GPU is weaked and cheaper into the Xbone APU but everything else is expensive...
Xbone APU (5 billions transistors, ~450mm²)
+ CPU 8-core Jaguar
+ GPU 12CUs
+ 256bits Memory Controller
+ 4 DataMoves units
+ 32MB eSRAM
PS4 APU (3 billions transistors, ~250mm²)
+ CPU 8-core Jaguar
+ GPU 18CUs
+ 256bits Memory Controller
The biggest difference between APU is the 4 DataMoves units and 32MB of eSRAM... only the eSRAM is close to 2 billion transistors.
The size are my estimates based in the official transistors counts... 450mm² vs 250mm².
Think like the Xbone have a "PS3 Cell" APU and PS4 have a "normal PC" APU.

Thanks for posting that information much appreciated. Had forgotten about the SRAM and didn't even know what DataMove units were!
