I think nvidia stopped production for 2xxx series.pretty likely. surely Nvidia doesn't want AMD hogging all the PR
then the gap between the 3050, 3050 Ti and the 3060 would be pretty small. that hasn't stopped Nvidia before, with the 2060S and 2070 on shelves at the same time, I guess
My guess would be
3070 = 2080ti
3060ti = 2080 super
3060 = 2080 non super
3050ti = 2070 super
3050 = 2060 super
