Under 1w/gh. Not bad. Not bad at all!
Actually, it's quite horrible. It's not even close to what was promised.
Prospero X-1 will scan 100Ghash while using less than 55 Watts and Prospero X-3 will be able to scan an outstanding 2000Ghash while using less than 1050 Watt.
Not trying to stoke the fire, I'm genuinely curious, but are there any machines that are currently available that are using .55 W/Ghash?
