Yeah the newbie is right 3060ti seem to be best at power for hash.
3080 are more dense
My 3080 does 95 mh at 230 watts. this is 2.42 watts per mh
my 3060ti does 60 mh at 125 watts this is 2.0833 watts per mh
But price of the card matters
and availability matters.
I am only mining so for me I take
any and all of the below
amd 5500
amd 5600
amd 5700
nvidia 3060ti
nividia 3080
they need to be at a decent price and available and I buy them.
In a magical world. I would take all 3060ti's put them on an onda d1800 board.
I would have 4 cards per board
1 zotac zt-a3061e=10m
3 evga 08g-p5-3667-kr.
this mobo would do. about 240mh at about 600 watts and just run baby.
I would have 50 mobos set this way total of 12000mh or about 890 usd of eth a day.
Problem is I can't get enough cards for 1 or 2 mobos no less 50.
