This then leads me to believe that GP100 and GP102 is essentially the same die except GP100 has an HBM memory controller, and GP102 has GDDR5/5X. Both have the same 3840 style clusters, and probably have the same double precision components (because you'd imagine Nvidia would capitalize on GP102 not needing double precision units, and using the space for more single precision.)
This then means that the GP102 should have similar double precision to GP100, except Nvidia is cheaping out and even disabling it on Quadro parts now. Now, before someone comments "but GP100 only has 3584 enabled single precision shaders and is full die," it is not, look at the whitepaper for GP100, it has 3840.
Now, this is purely speculation, but a lot of this lines up and sounds very Nvidia. I really do get an odd feeling that GP102 is GP100 double precision and all, just with the HBM memory controller replaced.
GP102 has exactly zero DP units, so I don't think it's capable of DP period.
GP100 actually has a 2:1 ratio of SP:DP units, and it has only 3584 SP units, not 3840. So it's 3584 SP units + 1792 DP units, along with HBM memory controller. Quite a different beast compared to GP102.
