The Quark processors are going to be incredibly small, and powerefficient. According to Intel, they will be one-fifth the size of the smallest Atom processor, and it will use one-tenth of the power.
Intel CEO Brian Kraznich has the following to say about the use of the Quark processor:
Smartphones and tablets are not the end-state. The next wave of computing is still being defined. Wearable computers and sophisticated sensors and robotics are only some of the initial applications.
Intel will have samples of the new chip ready for the fourth quarter this year, but we shouldn't expect to see Quark in wide use until next year. The first run of the chips will likely find their way into "embedded" technologies.
