Moving away from the Xbox 360's PowerPC-based architecture—back to the x86 architecture used in the original Xbox—the console features an Advanced Micro Devices processor built around the x86-64 instruction set. The Xbox One places an increased emphasis on cloud computing and entertainment integration, offering the ability to overlay live television programming from an existing set-top box with an enhanced program guide, split-screen multitasking of applications, and improved second-screensupport. The console optionally includes an upgraded Kinect sensor, providing richer motion tracking and voice recognition for use in its graphical user interface (GUI) and games. The Xbox One also offers the ability for users to record and share highlights from or live-stream gameplay. The console's controller was refined over that of the Xbox 360, with a redesigned D-pad and triggers capable of delivering directional haptic feedback.
