The PlayStation 4 or PS4 as it’s commonly know is a home video game console developed by Sony Computer Entertainment. It is a the successor to the PlayStation 3 and competes with Nintendo’s Wii U and Microsoft’s Xbox One, as part of the eighth generation of video game consoles.
Moving away from the more complex Cell micro architecture of its predecessor, the console features an AMD Accelerated Processing Unit (APU) built upon the x86-64 architecture, which can theoretically peak at 1.84 teraflops. AMD stated that it was the “most powerful” APU they had developed to date. The PlayStation 4 places an increased emphasis on social interaction and integration with other devices and services, including the ability to play games off-console on PlayStation Vita and supported Sony Xperia mobile devices using “Remote Play”.
It also has the ability to stream gameplay online or to friends, with them controlling gameplay remotely (“Share Play”). The console’s controller was also redesigned and improved over the PlayStation 3, with improved buttons and analog sticks, and an integrated touchpad among other changes.
Late in 2016, Sony unveiled two hardware revisions of PlayStation 4 being a slim build of the console, and a “Pro” version with an upgraded GPU and higher CPU clock rate to support 4K gameplay on supported titles. All models, including the original sold in 2013, support HDR10 high-dynamic-range color.
