Expensive, maybe a little. Hot, definitely yes. Nehalem is 731M transistors... Quad Penryn was ~820M transistors, so total count actually went down
. This is because Intel traded 4mb less L2 cache for more useful stuff, like triple channel memory controllers.
Silicon size doesn't reflect on the package size, or vice versa. More than likely the die size will be the same as Penryn.
