I don't think Nvidia wants consumer dice as large as Maxwell. AMD isn't in a good place vis-a-vis competitiveness ATM, so I don't see NV going with large dies. Again, I could be wrong, but uarch gains and perf/watt on consumer Volta GPUs will be enough - maybe will a small bump in die size. I'll be happy if I'm wrong, but NV is highly valued by Wall Street now, so profits come first.I dont think so. It should be possible to get these numbers into 600mm², 400mm² like with Maxwell. Bouowmx already showes the scaling which are worst case numbers, but a gaming chip will be smaller. GP102 will only scale shaders up and features. V100 had Tensor Cores, 50% more nvlinks, 2mb additional l2 cache and 45% more l1/Shared Memory per SM compared to GP100. And nevertheless they increased shader count by 40% with just 33% more die size.
GV102 won't have tensor cores (maybe a few for compatibility), won't have interfaces like nvlink which need to scale, probably won't have a increased l2 cache and scaling of L1 Cache will probably be between 15-33%. Additionally we have the 12FFN process which is unknown. Just because GV100 doesn't show scaling means nothing. Building such a big chip with a bit lower density might improve yield substantially. GV102 might have a 5% higher transistor density and then you're easy under 600mm².
