Two reasons why I don't believe this to be true...Originally Posted by Pazgaz
1) The market segment for the Titan GPUs is already incredibly small, and splitting them up into two, even smaller segments is probably going to hurt profits, more than help. I doubt nVidia is going to bother to spend extra money in order to manufacture two different types of ultra-top-end GPUs just to try and price gouge people at $100 per GB of VRAM.
2) The amount of VRAM on the PCB is determined by the GPU's memory interface:
GDDR5/X 256-bit = 2/4/ 8/16/32GB
GDDR5/X 384-bit = 3/6/12/24/48GB
HBM2 4096-bit = 4/8/12/16/20/24GB? (I'm guessing here, but it could also be 4/8/16/32GB like we see with 256-bit)
Now, all of the articles say that nVidia is going to "unveil" this new GPU, but that could mean anything. It could mean only spoken words with a picture on screen with no model or solid release date in sight, or a non-working mock-up model of the GPU, or a fully working GPU... we have no idea.
However, if nVidia is going to actually unveil a new Titan GPU at GamesCom and announce a release date in the near future, then my guess is that it's going to be G5X memory, and not HBM2. HBM2 isn't even available in the wild at this time, so for nVidia to offer it on a consumer-level GPU is absurd, because they release their GPUs like this: Tesla (Supercomputing/Deep Learning) > Quadro (Workstation) > GeForce (Gaming). I highly doubt that nVidia is going to cut into the super-scarce supply of HBM2 just so they can charge pennies on the dollar for it, when they could easily be making thousands of dollars per GPU in the Tesla or Quadro market.
So, with that said, if the GPU is going to be using the standard G5X VRAM, then it's either going to be 256-bit or 384-bit, and you can't have both 12GB and 16GB models on the same interface.
