just trying to do back of the envelope calcs... for them to buy 60 PH for $5.75m would mean buying circa 10 petahash per $1m.. which seems a little cheap.  If they're able to retail the chips for $1/gh (or lowest cost, over time, they said would be $0.5/gh), i don't think they have a 10x margin in there.. not even 5x.   lets assume 2x at most... so $5.75m probably bought them 30 PH and maybe i concede best case 60 PH and more likely 30-40 PH IMHO.

also, what we don't know is if that is just the wafer cost, or whether it includes all the other things you need to make a chip (substrate, packaging, testing etc)

i think its safe to say that buying each petahash for less than $0.2M/PH is pretty good going.   For it to be less than $0.1/PH would be lower than the lowest price i've ever heard of.  not impossible, but seriously unlikely.

And you've got to factor in whether they can SELL them, since their new biz model is selling chips, not mining... thus they need to find punters for 60 PH... of lousy chips that aren't competitive.  Heck, they're almost double the power of KnCMiner's latest chips and even after Spondoolies announces what their final specs will be, i suspect the AM chip isn't as power efficient as a SP chip... thus for AM to sell so many petahashes of an inefficient and power hungry chip will be very good going.
