Phab2 Pro relies on its quad-core Snapdragon 652 processor to run Tango's AR capabilities. Qualcomm even says that since its processors are optimized for the technology, Tango ends up using less processing power than a normal app and consumes less than two watts. By removing the need for extra hardware besides a depth sensor and a motion tracking camera, the partners are making it easy for phonemakers to adopt the AR tech. Tango, if you'll recall, can superimpose images over the real world through a device's camera. One of its applications is helping you visualize what your house would look like before you even start renovating or replacing your furniture.
