In production we use our US partner developed ASIC chips and motherboards produced by us
The BIG sticking point is that "20 nm" part of their spec - I've not seen ANYONE from an ASIC company claiming to be working with a 20nm process.
They also say the CHIP efficiency is .24w/GH, the MACHINE efficiency is .26w/GH, yet the machine is "designed to be underclocked" - voltage converters for typical low-voltage applications like SHA256 ASIC do NOT achieve a well over 90% efficiency, and there seems to be ZERO allowance in those specs for the power consumed by the controler board and other parts needed for the ASIC to talk to the outside world.
Definitely a "I want to at least see a review from a few REPUTABLE sources" item before I will believe it's real.
