The big issue is going to be supply. Nvidia is still having difficulty keeping up with demand for Ampere GPUs. Is there enough GDDR6 and GDDR6X to go around for all the doubled VRAM models? GDDR6 is probably okay, but GDDR6X only comes from Micron, and 3080/3090 are the only GPUs that use it, so Nvidia needs to be very careful about how much memory it orders. Not enough and it can't do 3080, never mind 3080 Ti and 3090. Too much and it would have to make everything into a 3080 Ti/3090 to get rid of the excess. Actually, 3060 with 12GB of GDDR6X would be an interesting alternative. I don't know if the GA104/GA106 GPUs support GDDR6X, though. Would love to see a 12GB GDDR6X 192-bit bus card for around $300-$350, but that's probably a pipe dream.
