The PlayStation 4 is an upcoming video game console from Sony Computer Entertainment. Moving away from the Cell architecture of its successor, the PlayStation 3, it will feature an AMD processor based around the x86-64 instruction set. This is intended to make video game development easier on the next-generation console, attracting a broader range of developers. Other notable hardware features of the PS4 include 8 GB of unified memory in the form of GDDR5, a faster Blue-ray disc drive, and dedicated custom chips for processing audio, video and background tasks. Among new applications and services, Sony plans to debut Gaikai, a cloud-based gaming service that hosts downloadable content and games. By incorporating a 'share' button on the new controller and making it possible to view in-game play streamed live from friends, Sony plans to place more focus on social gameplay.
