On 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.

I will make the setence better,  "efficiency, density and price".
