Wow that's very disappointing. Just 88 Sol/s for 2080ti with 144_5? I already get now 80 Sol/s with 1080ti at full power. That's just 10% increase for nearly double the money for the new GPU. Bummer.
Perhaps EWBF_ can do some magic with new code optimizations or perhaps using Tensor Cores or RT Cores for mining too - if that's possible in any way I don't know. Otherwise Turing will be a big flop for us miners

Video cards are sold quite recently and software manufacturers have not had time to optimize software for the new architecture.
But from the majority of tests it is clear that the new models have a good potential on some algorithms. The manufacturer stated that these models were not produced for mining

The only disadvantage of new video cards is the expensive price.
