PlayStation 4 (PS4) is a line of home video game consoles developed by Sony Interactive Entertainment. Announced as the successor to the PlayStation 3 during a press conference on February 20, 2013, it was launched on November 15 in North America, November 29 in Europe, South America and Australia; and February 22, 2014, in Japan. It competes with Nintendo's Wii U and Microsoft's Xbox One, as part of the eighth generation of video game consoles.

PlayStation 4 Slim (officially marketed simply as PlayStation 4 or PS4) was unveiled on September 7, 2016. It is a revision of the original PS4 hardware with a streamlined form factor. It reduced power consumption by 30%. The new casing is 40% smaller, and carries a rounded body with a matte finish on the top of the console rather than a two-tone finish. The two USB ports on the front have a larger gap between them, and the optical audio port was removed. It ships with a minor update to the DualShock 4 controller, with the light bar visible through the top of the touchpad. The PS4 Slim was released at the same price point as the original PS4 model. PlayStation 4 Pro or PS4 Pro for short was unveiled on September 7, 2016. It is an updated version of the PlayStation 4 with improved hardware, including an upgraded GPU with 4.2 teraflops of processing power, and higher CPU clock. It is designed primarily to enable selected games to be playable at 4K resolution, and improved quality for PlayStation VR. All games are backwards and forward compatible between PS4 and PS4 Pro, but games with optimizations will have improved graphics performance on PS4 Pro. Although capable of streaming 4K video from online sources, PS4 Pro does not support Ultra HD Blu-ray. Additionally the PS4 Pro is the only PS4 model which can remote play at 1080p. The other models are limited to 720p.
