RTX 2060 Super GPU BEST GPU for Mining? RTX 2060 Super Beat 1660 Super Mining?

In this days lower power consumption beats high hashrate so dear brother, a rig full of GTX 1660 supers consumes less power than a rig full of RTX 2060 Super, that's if efficiency is your thing though.

1660S and 2060S have nearly the same hash per watt ratio with a little plus for the 2060S - so your comparison is nuts. You write in your last sentence - efficiency and efficiency is watt per hash / hash per watt.
And you need less cards for same hash with the 2060S - give you also more efficiency.

P106-100 6GB very old video cards, analogue of GTX 1060 for mining. I don't want to compare hashrate and power consumption

What's wrong with comparing hashrate/power usage between generations? Pascal only has 25% worse H/W compared to Turing on FLUX or XEQ. ETH is irrelevant because it will disappear one day.

If I can get a P106 6GB for $70 or a RTX 2060 super for $300 while I pay just 5.4¢/kWh effective for power, the choice is obvious. Even when accounting for the price of the system parts, the P106 has more profit per dollar.

The P106 6GB is not the same with the RTX 2060 Super which is 8 GB and can mine Ethereum more than the P106 6GB,the difference in hash rate is almost double in RTX 2060 Super which can do like 44.25 Mhsh compared to the near 25 Mhsh of the P106 6B so I don't see any real comparison between the two cards with RTX 2060 Super clear being the superior.I am thinking seriously to upgrade my mining rig with 1 such card or two of them and I will get almost 90 Mhsh for just 240 Watt which is not that bad,definitely the best card to buy now in our time as it is really cheap in price now.

Even if Eth disappears one day,ETC surely will be with us until the end of time as the developers of ETC told us they will keep it in PoW for as long as it will exist.

I would not bet on Ethereum mining classic because there will be a lot of ASICs that will go there after Ethereum mining.

I see a lot of offers to sell the 1660S video card, probably because it does not give the best performance when mining other coins.
