In fact, the margin cost per chip is less than $0.8 a piece, that is hopefully $0.8 per GH/s. Of course, if we consider the cost of heat sinks, fans, PCBs, power supplies, and the disperse of the initial NRE cost into each GH/s, it will be significantly higher, but still within a single digit dollars per GH/s.
:O
That is really low price, amazing. Guess it helps to have contacts in the right place that will do it at cost price for you. Guess I'm a little to use to prices to manufacture them over here in the UK or USA. It would be more expensive.
