Apple's die size
The A10 is the largest one they've done. What I'm curious about is what is all that extra area for? They've grown by 30% and the small cores could only account for a tiny fraction of that. I'm sure the image processing for the dual camera is part of that, but can't begin to account for it all.
A6 - 96 sq mm
A7 - 102 sq mm
A8 - 89 sq mm
A9 - 96 sq mm / 104 sq mm (TSMC / Samsung)
A10 - 125 sq mm
