A slide spotted by CNET reveals Intel already has plans for Atom all the way down to 15nm. Unfortunately, the slide doesn't provide a timescale so we don't know within how many years these chips will hit the market.
At an IDF technical session Tuesday entitled "Intel Atom Processor Based System-on-a-chip (SoC)," Raj Yavatkar, an Intel Fellow and director of SOC architecture, displayed the slide above. One of the interesting aspects of the chart is that it shows the number of Atom chips for certain market segments increasing as the process technology gets smaller.
For instance, where the chart shows only one Atom N (Netbook) series at 45 nanometers, at 22 nanometers it shows four N series processors and at 15 nanometers five N series chips. And even more Z series (handhelds and smartphones) and E series (typically embedded in car-related electronics) at 15 nanometers.
