What’s the probability that a 48 core 3980 is on the cards?
I don’t know how feasible it is to add more in the empty space near the other chips.
It looks like the 3960X and 3970X are using 4 chiplets on the package. The package is the same dimensions as EPYC which is designed for 8 chiplets, as we all know. 3990X will use all 8 chiplets spaces (8x8 cores), so the 3980X would use 8x6 cores.
The 3990X looks like it's intended to be an Intel-crushing Halo product done for no other reason than AMD can, the omission of 3980X right now shows AMD can cater for a 48 core model if there is a call for it.
And I tell you something, I think there will be. I see the 3990X coming in about 3 grand. At that price I can see it being in big demand for those that would make use of it. There'd be no reason then not to offer a 48 core version somewhere around £2,400
