We wish we would be able to do that but the silicon is not this cheap. The only way we could sell 2th @ $1000 would be to loose money on each miner "sold".
Care to give some more insights in to the cost structure?
For the asic, allow me to make a guestimate based on cointerra's specs.
3 100mm² dies in a package yields 502-720 GH /chip
Lets go with the low estimate gives 166GH per die.
A 300mm wafer yields ~600 10x10mm² candidates or 100TH (at 100% yield). AFAIK, processed 28nm wafer cost less than $4000 in volume. Low volume runs may add significantly to that, if you have to go through to an intermediary.
Let be generous and for easy math put it $10,000 per wafer if you include yield, slicing, packaging, handling,.. thats ~$100/TH.
Now thats only silicon cost, excluding NRE and of course there are other costs, like PCB, assembly, housing, cooling, PSU, etc, but I find it hard to understand how over time, you would not be able to sell at (much) less than $500/TH. Am I way off in my silicon cost estimate? Or what else is so expensive? PCBs?
