You buying these numbers ?
"As for the mining performance itself, the GeForce RTX 3080 has a mining rate of 73-74 MH/s out of the box on Ethereum DaggerHashimoto algorithm. The performance reaches up to 82-84 MH/s and overclocking the card leads to a maximum performance output of up to 92-93 MH/s. Currently, the AMD Radeon RX 5700 XT outputs around 50-54 MH/s while the GeForce RTX 2080 Ti delivers up to 54 MH/s."
https://wccftech.com/nvidia-geforce-rtx-3080-ethereum-crypto-mining-performance-leaks-out/I've read that there will be overclocked version of this card in the future, of course you could probably overclock these cards...
That article quotes an article below that goes into a little more depth on overclocks and wattage for eth.
https://videocardz.com/newz/nvidia-geforce-rtx-3080-ethereum-daggerhashimoto-mining-performanceTom's hardware seems to confirm it
"We grabbed NiceHashminer and ran the benchmark mode, which failed on most of the hashing algorithms.
It did work on Dagger Hashimoto (Ethash), however, generating a result of 80 MH/s. That's nearly double the 2080 Ti's 43 MH/s and more than double the 2080 FE's 34.6 MH/s"
