EDIT: 0.7w/gh is that at the chip or wall? If it's at the chip, then that's pretty good, around middle of the pack. If it's at the wall, that's one of the more if not most efficient chips on the market (that I'm aware of).
I read it as being 0.7w/gh at the 12V input, which means probably about 0.5 at the chip and 0.9 at the wall depending on how efficient a PSU you buy.
Interesting. It's a near certainty that these are not our own chips but I'm racking my brain trying to figure out whose they can be. It's not coincraft as those chips are much less powerful and slightly less efficient, it's not BFL since their chips don't exist yet as far as I know and even if they did they'd be about half as powerful last I heard (600gh/s requiring 2 chips; though too be fair I haven't been following BFL for a while), it's not Blackarrow since their chips don't exist, I don't recall Cointerra selling chips so it's probably not them, Avalon, Asicminer, Antminer, and Bitfury don't have 28nm chips, which leaves us with Hashfast who have been confirmed to have an abundance of chips and whose stats sound quite close to ActM's offerings:
Power Consumption at the chip: 0.65 Watt per Gigahash /sec +/- 20%
Hashing Output: Up to 800 GH/s (overclocked)
Hashing Output: 400 GH/s (nominal)
and if we look at the EVO boards:
Typical Bitcoin Mining Performance: 675 GH/s +/- 20%
Size: 4.5″ wide by 12″ long
The price per chip has not been put on their website but if ActM is buying 100TH/s per month at the nominal rate of 400gh/s that would be 250 chips per month.
Does all of the above sound about right?
EDIT: 150 TH/s per month would be 375 chips per month
This picture will do me just fine..
