There is no consumer use case for that so basically inexistent market. It would be rather dumb of Nvidia (or any other for that matter) to willingly cut its entreprise margins for such a non product. The only one doing lots of VRAM are Apple and nobody really care because performance is not that competitive and price is about as bad as entreprise stuff. I still think modular arch will stay for consumers products there much more benefits to that than chasing a bit more perf for low volume products. Apple can get away wit their shenanigans because they subsidize their high-end chips with the iPhone. If they could only sell Macs it would extremely unsustainable (like the PowerPC venture showed).
