That said we only KnC's package size, not die size. Large package size, does not necessarily correlate to a large die size.
Ill grant you that, but I havent heard anyone refute hashfast's argument that the minimum estimate of KnC's die size based on the package/underfull dimensions would be on the order of 900mm³. Thats not just a little bit bigger, thats an epic size.

I'm sure most here don't care if KNC chips are, indeed, full-custom or standard cell -- as long as the performance is within spec. I know there are some 28nm fetishists around, who think 28nm node = god, but hopefully Bitfury 55nm chips castrated their nanolust.
