They will have to otherwise reviews won't look good if future ports are equally as bad as forgotten.
I'm firmly holding out for the 50xx series now given even rdna 3/ada is ******** the bed now especially if path tracing becomes more common
AMD are gonna have the same problem.
A 4096 core chip, will be 256bit on the current architecture, is 16GB. Next logical step down from the 7900XT.
Then anything below that, won't be able to hit 16GB. They could do a 192bit card with 12GB.
If there are 4GB chips, then that would solve Nvidia and AMD's problems as they would be able to double memory on the same bus. Haven't seen anyone use them yet. The 4090 and 7900XTX use 12 x 2GB chips.
