I honestly don't know how well a 24gb 5090 will move, no matter how fast it is. I feel like the gamers will go for stuff like 4080 super, 4070 ti super, next gen AMD. For productivity users, there's 3090, 4090, A6000.
Maybe I'm wrong and the card doesn't need to be very good to sell because GPUs are so burning hot right now.
GDDR7 memory chips will be in production with either 2 or 3 GB sizes, which means 36GB of VRAM on 384-bit bus could be a possibility for next gen.
Why actually build the 36 GB one though? What gaming application will be able to take advantage of more than 24 for the lifetime of 5090? 5090 will be irrelevant by the time the next gen of consoles releases, and the current one has 16 GB for VRAM and system RAM combined. 24 is basically perfect for top end gaming card.
And 36 will be even more self-canibalizing for professional cards market.
So it's unnecessary, expensive, and canibalizing. Not happening.
36GB is certainly a possibility. VRAM demand is high across multiple markets. Currently you can get a 24GB 4090 or 48GB A6000 Ada. There's certainly a possibility of seeing 36GB 5090 and 72GB A6000 Blackwell (B6000?)
