It definitely isn't the king of mining in terms of efficiency for ETH. 2.52W/MH puts it roughly equal to my 2080.
If it is hampered by the gddr6x, then the 3070 should fare better at ETH - 60MH @ 150W? That would be rx5700 level.
uh? you say equal and yet you did not say your hashrate, taking the value from whattomine, it says, 2080, 38 mhs 160 watts, rx 5700 or 3070 will not come close to price performance of the 3080 and density, you can deny all day long but when numbers are real, is time you trolls accept the reality, at moment there is nothing better than 3080 overall which yes makes it the gpu king of mining.
Yes i said equal, as you were talking about efficiency in terms of W/MH for ETH. Based on that metric, i disagree with your statement that the 3080 is the "king of mining in terms of efficiency".
The hashrate of my 2080 does not matter as we are talking about W/MH, but fwiw, on average, my cards do 41.4MH @ 105W-110W atw.
