Chipworks Provides First Apple A7 Die Shotby Anand Lal Shimpi on September 20, 2013 5:57 PM EST
Hot on the heels of their Samsung 28nm confirmation, Chipworks just sent over the first die shot of a delayered Apple A7. An annotated version is following early next week, but I've highlighted two sections of interest:
In yellow we have what appears to be the two Cyclone CPU cores. If those are indeed the two CPU cores, the layout does seem different than what we saw last year with Swift in the A6. Also note that the percentage of die area dedicated to the CPU appears to have grown a small amount (now roughly 17% of the total SoC area).
To the lower right I found four replicated blocks with some shared logic in between (highlighted in light blue). I'm wondering if this area isn't the 4-cluster PowerVR G6430 from IMG. All of this is just a quick educated guess of course.

Apple has already confirmed die size (102mm^2) and roughly confirmed transistor count (over 1B) of the A7 so everything else is mostly a known quantity at this point.
