Did I read it correctly? geezed, seems like a Bot with auto reply to me, targeting only on subjects but not the actual concern by the OP
@OP
Aside from online calculators that were previously suggested, there are a lot of threads here pertaining on specific cards. these are actual encounters by the members that you could rely on.
Yeah, I read it twice too I wasn't sure if it's me not comprehending stuff before having coffee, or a bot.
Anyway, my original question was related to how to differentiate between two or more rigs.
Let's say rig A is 300 Mh/s at 1350 W with a price of 4000$, and
rig B is 167 Mh/s at 720 W at a cost of 1600$.
Which one to get?
What I came up with is dividing hash rate with wattage that yields a sort of mining efficiency ratio.
And then divide that ratio with the cost of the rig.
Hope this helps anybody to select between rigs.
