A little early but at least the future is looking good

16nm or even 14nm in Einstein for a supposed 2016 release.

Even if currently nothing concrete for the current Kepler architecture following Maxwell architecture for a long time (2014, 20 nm) is known, nVidia still has naturally been the long-term future and researching for the proposed chip. To a long-term project, the code name was now well known: the architecture should follow the Einstein-Maxwell-architecture. This code name nVidia remains within the rest of the younger tradition: the architecture Fermi, Kepler, Maxwell and Einstein were all now known scientists dedicated ( Enrico Fermi , Kepler , James Clerk Maxwell and Albert Einstein ) .
Using the Einstein architecture should improve the overall usability of the nVidia graphics chips for GPGPU tasks probably more, all been said so far on this but has probably only character studies, should not be long gearbeit on a real circuit diagram of Einstein graphics chips. For production size and thus the Einstein Erscheingstermin architecture there is conflicting evidence, however: While some see Einstein as 14nm or 16nm chip in 2016, others speak of a 10nm chip in 2018. If, however, the Einstein-Maxwell-building is really the architecture follows directly, may well be correct first resolution - with the 14nm manufacturing, however, as the contract manufacturer TSMC and Globalfoundries future will follow in this issue of the Intel production steps.
