Basically this is a war on. It is to develop the cheapest most efficient chips and there are only two real players Spondoolies versus BitFury with the capabilities to do this level of design.
You can't be serious.
Are you forgetting about bitmain, innosilicon, 21e6, asicminer, knc, or blackarrow?
SP30 'Rockerbox' - 200 GH/s; "The first ASIC company to break the 0.5 W/GHs barrier
I'm curious to know how that is possible without chips in hand.
Bitfury gen1 chips are capable of more than 0.5w/gh at the wall and blackarrows minion can do it as well.
I've also never known bitfury or spondoolies to be the cheapest.
Is there actually any point in time where spondoolies had the best $/gh or w/gh ratio?
