I think Nvidia will be a lot more structured this time around with how they do their Vram. My predictions are:
4090: 24GB G6X
4080: 16GB G6X
4070: 12GB G6
4060: 8GB G6
The 4090 is supposed to have a 384bit bus, 4080 256 bit bus and 4070 is a 192 bit bus. So a 4090 can either have 12 or 24GB of Vram, 4080 can either have 8 or 16gb of vram and 4070 can either have 6 or 12gb of vram. (Technically they can have more but Nvidia isn't gonna give 4070 more than 12).
The thing with Ampere is Nvidia wanted to give the 3080 high bandwidth Vram but only 1GB GDDR6X memory modules were ready on time. They could have done what they did with the 3090 and had Vram on the backside of the GPU but then the cost would have gone way up. They could have given the 3070 16GB but I think they didn't want 3070 stepping on 3080s shoes. They did technically give the 3070 16GB but only on laptops which they named as "3080 mobile." Also due to AMD being competitive, they didn't want to give the 3060 only 6GB so they upped that to 12GB.
But now we do have 2GB GDDR6X memory modules, I think Nvidia will structure their GPUs far better this time around but that also means the 60 class probably won't be getting such a high Vram count.
