Based on available die analysis, Skylake core including L2 is ~8.7 mm^2 and A9 cores including L2 is ~6.8 mm^2.

And it it targeted the same frequencies as Skylake, it would be using a larger amount of higher drive cells.

My point was that Paul's assertion is way way from being a proven fact.
Your point is?
