The PlayStation 4 (PS4) is an eighth-generation home video game console developed by Sony Interactive Entertainment. Announced as the successor to the PlayStation 3 in February 2013, it was launched on November 15 in North America, November 29 in Europe, South America and Australia, and on February 22, 2014, in Japan. It competes with Microsoft’s Xbox One and Nintendo’s Wii U and Switch.

The PS4 has sold more than 102 million consoles worldwide as of December 2018. The console was ranked the second best-selling console in the world during 2017, behind the Nintendo Switch and ahead of the Xbox One.


The PlayStation 4 uses an accelerated processing unit (APU) developed by AMD in cooperation with Sony. It combines a central processing unit (CPU) and graphics processing unit (GPU), as well as other components such as a memory controller and video decoder. The CPU consists of two quad-core Jaguar modules totaling 8 x86-64 cores, 7 of which are available for games. The GPU consists of 18 compute units based on the GCN architecture, totaling 1152 shader cores and can theoretically produce 1.84 TFLOPS; it also includes a hardware video encoder and decoder (VCE and UVD)


The PlayStation 4 features a 500 GB (1 TB models also available) hard drive for user-generated content. Games are not installed on the hard drive, but some must be installed onto the console’s built-in flash memory or an external USB 3.0 hard drive. The system software uses about 1 GB of storage and can be upgraded through game discs or downloaded from the PlayStation Network; updates may also be downloaded automatically when available to connected consoles.


In addition to standard input/output ports, the PS4 features two auxiliary ports: an optical audio output and a proprietary connector for the PlayStation Camera, a motion detection digital camera device. The console does not have an internal power supply; it must either be connected to an external power source using the included AC adapter, or batteries in the attached controller.
