It's hard to really parse out a well defined question from that, which is probably why he didn't get an answer.
But on the Broxton die size, I would imagine that 58mm^2 is probably not accurate since Cherryview was larger and less feature packed. In my defense, I was using information given publicly by Stacy Smith so if that information was inaccurate, my die size estimate would probably be wrong, too -- GIGO.
