What would be the hashrate of this machine?

650MH/s @ 750Watts

I wonder how much will it cost?
Really? You just quoted a random statement from a brand new account with 1(
ONE) post in the forum?
I say 12 MH/s @ 6000 Watts and that's provided there are such "ASICs" and this is not just FUD to drop the price of GPUs.
I saw above a question from one person: What would be the hashrate of this machine? and somebody replied: You can't read?
I decided to read all posts but did not see an answer besides that brand new account , and thought that was that

Why do you think it is 12 MH/s @ 6000 Watts ? This is really low, comparing with Panda B3 for example: 230 MH/s @ 1250 Watts.
