https://www.techpowerup.com/gpu-specs/nvidia-ga102.g930On techpowerup ga102 page has this table on 3080ti, how much this might be true that is another thing hehe but I somehow believe this table to be spot on. March next year perhaps? I don't think AMD will have anything in this bracket so nvidia will charge whatever they want. I still think 10gb is not enough in 2 years time, it is today and probably next year too, getting a 10gb now and reselling in 2 years is not something i would like to do. The only thing that remains is what will be the price of the 20gb, I predict maximum $849 which if you think about is not that bad, charging $899 or $999 might be just too much for it.
The specs aren't logical, the 3080Ti like that would be as fast, maybe even faster than the 3090 ! Keep in mind there was no 2090 so the 2080Ti could be as fast as possible, but here nvidia needs something squarely between the 3080 and the 3090, not something within 1 or 2% of the 3090.
