The issue memory bandwidth. If you look at Nvidias past you might be able to predict what they will have.
780 Ti 3GB-384-Bit-G5-7GHz ~ 336.6 GB/s
980 Ti 6GB-384-Bit-G5-7GHz ~ 336.6 GB/s
1080 Ti 11GB-352-Bit-G5X-11GHz ~ 484.4 GB/s
2080 Ti 11GB-352-Bit-G6-14GHz ~ 616 GB/s
780 Ti to 980 Ti there was no change in speed but delta color compression saw the biggest increase ~ 25%
980 Ti you got faster G5X (10GHz), 11GHz because 1080 Ti was launched much later in Pascal's life and again improved delta color compression ~ 20%
1080 Ti to 2080 Ti G5X to G6.
I suspect 3080 Ti to have either 22GB-352-Bit-18GHz or 12GB-384-Bit-18GHz.
Worse case is 12GB-384-Bit-16GHz.
It would be very interesting if Nvidia did something like 15GB-480-Bit or 14GB-448-Bit @ 16GHz.
