This week at IDF, new Intel CEO Brian Krzanich surprised the crowd by unveiling "Quark," an x86-based chip that is tiny and uses little power. It's meant for wearable devices and sensors, such as for medical devices. Intel President Renée James says it'll be a fifth the size and use a tenth the power of the smallest Atom chips, now mostly used in netbooks and some tablets.
She says they'll be "disposable," which may mean they'll be much, much cheaper than typical Intel chips. Pricing and availability, though, are unknown.
