FYI - in addition to the 7 questions I posted before, I asked Ken about the 10.488 TH miner he announced and this is the reply:
One more:
8. you said most recently that the 7-unit (7x 4U units) miner was going to be 10.488TH. then you released that the boards for the 55nm chips will only hold 24 chips, which would mean 45.6GH per board, so it would need to have 33 boards per 4U box. is that 10.488TH still the official figure?
The 10.488 TH/s System is 230 cards in 2 42U racks. 1 Base unit with 5 cards and 15 expansion cases daisy chained together.

Are those specs good or bad?
45gh per card seems pretty low density....
So, more than likely the "budget" option that we might see purchased (if we are selling these... I'm still not sure if we're just building the ActM operation with these chips.) will be having an affordable ($1K-$2K) base unit with expansion. This would provide 20 cards of hashing power or 912gh/s before any performance increases. My guess is that we will be able to clock these chips up a bit from 1.9gh/s with good stability and will be able to push this budget option up to and maybe slightly over 1TH/s.
But, yes, I agree. 2 42U racks for a little over 10TH/s seems a bit much. Imagine setting up a 1PH mine with those - you'd need 96 42U racks! Of course, that isn't what the 55nm offering is aimed at.
Good thing we have those 28nm FCICs on deck for bigger operations.
Try 200 racks. And about 3 MW of power and cooling.
