And that's due to the hashrate limiter. Not officially announced yet but already leaked, the GeForce RTX 3080 Ti offers a Hash Rate in Ethereum of 58 MH/s . Thus this GPU arrives limited by NVIDIA for cryptocurrency mining, in the hope that this will help improve stock availability for PC gamers.

That value is roughly half it should be, however, the RTX 3080 Ti is capable of reaching a Hash Rate of 58.04 MH/s mining Ethereum, so despite being limited to half the performance it is still profitable given the current values. This means that the new graphics card of the green team offers the same Hash Rate of the GeForce RTX 3060 Ti without limitations, but with a consumption of 299W , which is practically double. 

The RTX 3080 Ti will make use of the GA102-225 graphics chip, offering a total of 10,240 shading Cores, 320 TMUs / Tensor Cores, 112 ROPs, and 80 RT Cores. The graphics card will have frequencies of 1365/1665 MHz and will also be equipped with 12 GB of GDDR6X memory on a 384-bit bus and with a TDP of 350W.
