Word is a new A6 processor already in early testing in advance of the launch of the iPad 3 in spring 2012. The A6 chip is reportedly a 28nm process (compared with the A5's 45nm), meaning lower energy consumption and higher speeds.
The faster processor would improve the performance of Siri, iOS5's new integrated voice assistant, as well as host of other features, including still and video image capture.
