PlayStation 4, or PS4, is a video game console from Sony Computer Entertainment that launched in November 2013. Competitors include Nintendo’s Wii U and Microsoft’s Xbox One.
PS4 features an AMD x86-84 Accelerated Processing Unit and its graphic processing unit can perform 1.843 teraflops, making it the world’s most powerful games console (as of 2014). PS4 allows for social gameplay, incorporating a “share” button on the new controller and enabling a view of in-game play streamed live from friends. The console also enables interactivity with other services and devices.
DualShock 4 is PlayStation 4’s primary controller; it connects to the console via Bluetooth 2.1+EDR, and is equipped with several new features, including a built-in two-point capacitative touch pad on the front of the controller. The controller supports motion detection and improved vibration, in addition to support for the Windows PC platform. Worldwide, over 2.1 million consoles were sold by December 2013 and 7 million by April 2014.
