It would be 592,800 Gh, 593 Th, or 0.6Ph at 282mh/s a chip.
Why would they be running at 282mh/s?
I did mix up PH/s and TH/s, though. The current network hashrate is 370TH/s, so it would still be twice the current hashrate. Obviously, they could not currently be hashing.
They won't necessarily, but that' Avalons standard clock speed. Some will OC, some won't. Some will OCoverdose, some will be DOA. Some will err go missing.
