Thanks, now we know their yield per wafer is around 110Th/s
I'm terribly sorry that i made you lose the time needed to write all of that, but that is Cointerra chip, not Hashfast's one.
Doesnt make too much difference. Hashfast published their die size. Each chip has 4 dies of 81mm² IIRC. A 300mm wafer would hold ~800 die candidates for up to 200 chips x 500GH each = 100TH.
