If they're using that many cores, it's damn likely they will be different (weaker) than the current cores. I doubt they'll change the naming, however.

Assuming the cores wont be hot clocked, we can at least assume that they will only be half as capable at any given base clock speed. Surely the removal of hot-clock-ability will no doubt free up some space and complexity on the die, which in turn makes adding that many more cores possible.

Current rumour is that the GK104 will have 1536 CC's, think of that as a 768 CC GF1xx part. Of course clock speeds will be a bit more than half of the old hot clock speeds, most likely. I myself think they they will possibly be further reduced beyond just removing the hot clock, but not too drastically.
FFS I will stop using SPS and use CC's as that's the way NV defines them

I am getting your point now. I think we are thinking along the same lines. You are extrapolating the fit of the GK110 from GK104 I guess or even current gen. ie if that was done it may be impossible etc So that is why you are inclined to think the CC may be of "lighter" weight if it is 4096 CCs (if this holds true). I tend to think the opposite and it will not be the 4096 CCs but the CCs (basic unit) will not be far different from existing fermi ones.

But then the purported changes to the hot clock thing could also mean changes to least how they line up blah left to talking about that when you are drunk and you just nod your head as the world is spinning.....

..and i could be pulling this out of my arse as well hahahahahaha...all will be revealed i guess in a few days...PDXLAN or March
