But there's something to note: even the latest version of Claymore doesn't have support for the new Turing GPU architecture, so give it a few weeks and especially over the coming months, we'll see tuned Claymore versions ready for the additional GPU horsepower that Turing offers. Not that you'd run around buying RTX 2080/2080 Ti cards for mining, that's absurd.
Seriously, out of the box Ethereum mining performance of 50MH/s is insane. Even with the HBM2 memory on the Radeon RX Vega 64 it was really only able to push 38-40MH/s out of the box and 42MH/s when using the AMD blockchain optimized drivers/Compute mode enabled.
...
But when we have the 11GB of GDDR6 overclocked on the GeForce RTX 2080 Ti Founders Edition, we see the Ethereum mining performance scale up incredibly high, hitting 55MH/s. This is nearly twice the performance of the GTX 1080 TI, which is quite incredible.
