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.
would like to know for sure that the die is 81mm²... dies are rarely exactly 9x9 mm... so it'd be nice to know exactly how big it is to at least one decimal place rather than the very rough and unlikely sounding 9x9mm number. e.g.,if it was 9.5x9.5mm that'd be a 90mm² die.
makes a bigger difference when we're trying to calculate the gh per mm²
i also heard for instance and by comparison that knc has a 6.6mm x 6.6mm die = 43.5mm², which hashes at 650 GH for 4 chips, and each chip has 4 dies.. thus each die hashes at 40.625 GH... thus the gh/mm is 0.94 gh/mm²
