My bad, forgot about 5.0 devices being called GM1xx. Still, AFAIR there was little practical difference (in particular instruction set) between all but the compute capability 5.3 Tegra.
> Maxwell wasn't 1/3 it was 1/32 (no this isn't a typo) ;) this is the same (or even worse IIRC it's 1/64 now) with Pascal with the exclusion of the GP100, the Pascal Titan and Quadro cards are 1/32 or 1/64.
I did not say Maxwell had 1/3 DP flop rate, I said Kepler had that, but Maxwell was pushed by the 28 nm process (so they had to get rid of all DP ALUs).
> As I said NVIDIA keeps this for very limited silicon if you buy a desktop/workstation GPU even with Pascal don't expect DP/HP performance.
Never disagreed, but they can only do that because their professional compute division has grown big enough that it it worth designing different silicon; that shift happened in fact after Kepler, GK110 was more or less the same on GeForce and Tesla (e.g. 780 Ti and K40). They're also trying to find a good way to do market segmentation and DP ALU die area is an obvious candidate to play with. Still, no HP on GP102/104 is a curious thing, especially as the Tesla P4/P40 that oficially target ML/DL would really need it. My bet is they won't "forget" HP on lower-end Volta; not all consumer chips will support it, but unless they'll design different dies for GV102/104 (or whatever they'll call the non-DP Tesla uarch), which I doubt, some desktop parts will also support it.
