The PlayStation 4 is a home video game console from Sony Computer Entertainment. Announced as the successor to the PlayStation 3 during a press conference on 20 February 2013, it was launched on 15 November 2013 in North America, and 29 November 2013 in Europe and Australia. It competes with Nintendo's Wii U and Microsoft's Xbox One, as one of the eighth generation of video game consoles. Moving away from the more complex Cell architecture of its predecessor, the PlayStation 4 features an AMD x86-64 Accelerated Processing Unit, in hopes of attracting a broader range of developers and support for the system. The PlayStation 4's GPU can perform 1.843 teraflops. Sony calls the PlayStation 4 "the world's most powerful console" and, speaking to Edge magazine, numerous game developers described the performance difference between the PS4 and Xbox One as "'significant' and 'obvious'". The makers of PlayStation 4 intend to focus more on social gameplay over time, and incorporated a "share" button on the new controller and enabled a view of in-game play streamed live from friends.
