Low-cost Android tablets from little-known vendors with 3G capabilities may soon hit shelves with chips from Intel, which is looking to replace ARM processors in devices starting at $100. Intel on Tuesday struck a deal with Chinese chipmaker Rockchip to jointly make an Intel-based x86 Atom chip with an integrated 3G modem. The quad-core chip, based on Intel's Sofia architecture, will ship in the first half of 2015 and go into entry level tablets, said Intel CEO Brian Krzanich, during a conference call to discuss the deal.
