AnandTech heard details about Intel's Atom roadmap at the company's 2011 investor meeting, you can check it out over here.
It reveals 2013 will deliver the 22nm Silvermont and that a 14nm Airmont core is slated for 2014.
Far more interesting however is that Intel didn’t stop with Silvermont on their Atom roadmap. Intel’s roadmap goes out to 2014 and includes Silvermont’s successor: Airmont. We know even less about Airmont than we do Silvermont, but a good guess would be that it’s the tick in Intel’s tick-tock cadence for Atom. The biggest news here is that with a move to tick-tock for Atom, Intel is finally accelerating the production of Atom parts on their newer fab processes. Currently Atom processors are a year or more behind Core processors for using a new process, and even with Silvermont that’s still going to be the case. But for Airmont that window is shrinking: Airmont will be released on Intel’s forthcoming 14nm process in 2014, the same year as their respective Core processor. Intel hasn’t specified when in 2014 this will be, and it’s likely it will still be months after 14nm launches for Core processors, but nevertheless it’s much sooner than it has been before.
