Not really. Monolithic means one piece, solid without division, unbroken.

A side by side die on a substrate avoids the problem of poor yields vs. a true monolithic core. Just ask AMD about this and their K10. Yes there are trade-offs to either approach, but for a GPU because of it's highly parallel nature, I suspect the performance trade off will not be as severe vs a CPU, if done correctly. But that is speculation on my part.

It really comes down to cost, going with a gigantic single die as Nvidia did appears to have necessitated a price point way out of range. How do they take the large die and scale it down for the mainstream markets without making a completely different die?
