It's called the Blackminer F1. Site looks sketch, but its legit. Just google around a bit and you'll see.
1 BM F1 cost $2,500(smaller one they just released is $1,300 and half the speeds). It's eqiuvalent too 17-18 GTX 1070ti in terms of raw hashpower and uses 600 watts of power(compare to the 17-18 gtx 1070ti using about 2600 watts).
