Lol, what? Why did they even bother hyping up that shit when they know people would be expecting Kepler news and hence be disappointed.
VR-Zone said:The GK100 'Kepler' and its GK110 follow on were supposed to wrest that lead back to Nvidia, just a month or two from now. However, right now it looks a gone case, at least for the next half year. For whatever reasons, the GK104 upper mid-range part, a follow on to the GeForce 560 family, is now the top-end part to launch, and it can't - I mean can't - win over the HD7970 in any meaningful use. That role was reserved for the GK100 and follow ons.
Wasn't that (GK104 launching first, GK110 later) what the rumors suggested for quite a while already (though the timeframe might not be right)?
I can't really see the news here. The only question seemed to be if GK104 can beat (or equal) Tahiti or not. Ok so VR-Zone thinks it can't but don't say why. I'm not quite sure anymore it really can't given that it most likely is a chip with very similar size compared to Tahiti, factor in (in contrast to Tahiti) it won't have any features just for compute and it looks even better. Given the relatively conservative clocks/TDP AMD have chosen that might enable nvidia to compete quite easily with it (at least with the 7950).
Who knows, maybe Charlie was right and GK100 is cancelled while GK110 is basically to GK100 what GF110 was to GF100.

Though if you consider the past, AMD has had leaps and bounds better perf/mm^2 before - the real question is can they hold it with GCN-architecture?
That depends on the exact chip you're looking at, it wasn't really all that much recently. Cayman vs. GF114 is just a tiny bit better in perf/mm². Barts, being just very slightly larger than GF116, is of course better there wrt all of Cayman, GF114, GF116, quite massively so compared to GF116, though this one seems to be larger than it should be (if you compare how it scales down from GF114, I guess the mostly unnecessary 192bit bus when coupled with gddr5 and the 8 excess ROPs are at least partly to blame). Juniper is also much better in perf/mm² than GF116 (but again, GF116 just seems too big).Though if you consider the past, AMD has had leaps and bounds better perf/mm^2 before - the real question is can they hold it with GCN-architecture?

AMD had better perf/mm^2 in the past, mainly because
1) They didn't have all the GPGPU gunk that nVidia chose to put in
2) They didn't have a hot clock
With this generation
1) AMD has now gone down the GPGPU route, much like Fermi
2) nVidia has allegedly dropped the hot-clock
So, I would expect things to be much closer now
- though AMD would still have an advantage if they are on 28HPL, and NV is on 28HP...
Edit: Actually, that's a perf/w issue, not a perf/mm^2 issue, AFAIK
This is the best desktop graphics architecture and physical implementation ever. Some rough edges, but that's the long and short of it.
