Looks like the hard macro size for a dual core performance optimized A9 core on 40nm is 6.7mm2, which allows 2GHz operation @ 1.9W according to ARM. So it would be around 13.5mm2 for quad core.

Just doing the crude math, that would come out to be (not including I/O or other SOC units):

13.5 * (350/40)^2 = 1034 mm2

How big was the reticule on 6 inch wafers, again?


What part of "ARM7 core" don't you understand?
