Moving away from its predecessor's PowerPC-based architecture, Xbox One marks a shift back to the x86 architecture used in the original Xbox; it features an AMD Accelerated Processing Unit (APU) built around the x86-64 instruction set. Xbox One's controller was redesigned over the Xbox 360's, with a redesigned body, D-pad, and triggers capable of delivering directional haptic feedback. The console places an increased emphasis on cloud computing, as well as social networking features, and the ability to record and share video clips or screenshots from gameplay, or live-stream directly to streaming services such as Mixer and Twitch. Games can also be played off-console via a local area network on supported Windows 10 devices. The console can play Blu-ray Disc, and overlay live television programming from an existing set-top box or a digital tuner for digital terrestrial television with an enhanced program guide. The console optionally included a redesigned Kinect sensor, marketed as the "Kinect 2. 0", providing improved motion tracking and voice recognition.
