I don't see where there are any indications that this is GP100, and given that Nvidia has led with mid-range and small die processors with Kepler and Maxwell, I'm inclined to believe this is not big-die Pascal until shown more information to persuade me otherwise.
I tend to agree - though maybe HBM2 only makes sense on high-end GFX cards (esp. if NV wants to start w/8GB). Interesting times.
If this launches in 2016 it's going to Tesla only. If by some small miracle this launches in Geforce it will most likely 1) Months after the Tesla launch 2) Be in a $1,000 Titan only for several months 3) The Titan will be an cut-down version of the chip.
nVidia badly needs to refresh Tesla, so that's the main goal but there will probably be a Titan too. I'm sure it has GDDR5, but considering how small the die will be HBM1 is theoretically possible.
I wouldn't be surprised if they try to push an even higher price with the Titan this time. May have not worked in the past (Titan Z), but the market dynamics seem right for it this time... dieshrink, huge VRAM increase and likely at least double the performance. They can probably get away with $1.5K.
