The colleagues in Planet3dnow.de have published at this address the detailed picture of AMD's Carrizo APU.
Carrizo occupies an area of 250mm2 - more or less the same as Kaveri (245mm2) - but it has a pronounced rectangular shape, a different internal layout and integrates 3.1b transistors against Kaveri's 2.41b, using the same production process (28SHP GloFo).
We know that the space occupied by the two x86 Excavator modules is 28% lower than Steamroller (thanks to the use of High Density Cell libraries), and that the 5% IPC increase is mainly due to the double L1 cache, rising to 128KB from the original 64KB.
The southbridge should be located close to the I/O, in the upper right, and there are the 8 Compute Units of the GiP8 Volcanic Island GPU.
The image highlights once again the use of a dual Memory Controller / PHY. Kaveri incorporated a four channel controller with just two of them being active: 4CH-DDR3 or 4CH-GDDR5M (never enabled by AMD); at this point it is clear that Carrizo offers a similar configuration, probably with DDR3 / DDR4.
