Most processors with ARM architecture and graphic solutions are made on 28-nanometer technology. Although TSMC, the world's largest contract chip maker, is ready to start mass production of 20-nm technology in a couple of months, the first relevant projects to come before the end of 2014 or even early 2015.
For bitcoin the 20-nm solutions will be available later this week. This is a product of the Swedish company KnCMiner called Neptune, which is a set of five VLSI designed to perform the calculations in the system Bitcoin, and the control board. Neptune complex is able to provide performance at 3 terahash per second in energy consumption of about 2.1 kW.
For the production of such specific chips do not require a high-volume production, no high performance yield crystals. This allowed Neptune processors to become the first commercial 20-nm solutions. Related Products :
