14nm Bitcoin ASIC
We are still heavily involved in the 14nm ASIC project.
We are happy to report that after bringing on board more talent we have exceeded our initial 0.3W/Ghash target by 4.3 times by employing all techniques possible in ASIC and algorithm design. Our current design efficiency is now 70mW/Ghash (0.07W/Ghash) which allows us to build a 1 Terrahash chip in a single die while using 70 Watts at chip level. This will allow development of a 20Thash machine while using 1.5kw.
We intend to make this chip available for sale only from stock (No pre-orders)
In addition to that - you should also use the same form factor of the hash boards in the X3. Thus allowing existing customers to simply upgrade the machines they have and save on all that shipping. As compensation for screwing over those who thought you were going to deliver in May 2014, perhaps upgrading each x3 box to say 10 or 20 TH with the new chips would be a reasonable expectation.
By the way - when you build the new machines - the design of the X3 over all was good. Please use some better screws that don't get stripped when you remove them. The heat sinks for the DC chips should not be super glued on - instead use a screw mount or retention clip. Having to pry those suckers off is a pain in the butt.
Also - please include an on/off switch wired in, so that we don't just pull the plug to turn it off.
