nicehash have a new post.
The first actual mining performance was confirmed to be at around 58 MH/s on the DaggerHashimoto algorithm. The miner (mining software) used to perform this test is currently unknown.
Currently known GPU models and its hashrates:
MSI GeForce RTX 3070 59.03 MH/S
ASUS GeForce RTX 3070 58.56 MH/s
GeForce RTX 3070 FE 49.97 MH/s
looks a bit low than my expectations. I was expecting around 65 MH/S
will have to wait until tomorrow for the drivers to be released to test it out myself.
