In addition, the S4 line will be able to support 3D video capture as well as 3D HD video playback. Other capabilities include augmented reality functions and the ability to run gesture-based apps. Thanks to device-maker programmable digital signal processing, the S4 line offers better audio for users.
Certain hardware makers are already sampling the S4 chips and smartphones and tablets containing the S4 will be in the marketplace early next year. The highest-end of the S4 series, the quad-core 8064, is still under development and will be found in products in the marketplace during the second half of 2012.
