PlayStation 4 belongs to the eighth generation of consoles, as a successor to PS3, and will compete with Nintendo's Wii U and Microsoft's Xbox One on the market, and PlayStation 4 uses AMD-based X86-64 architecture processors,
Unlike Playstation®3, which uses the cell architecture. The purpose of replacing the processor architecture is to make the process of game development easier to attract more different developers to join. Such a change comes from the experience Sony has learned during the development, manufacture and sale of PlayStation 3.
Other important hardware features of PlayStation 4 include built-in 8 GB of GDDR5 integrated memory, faster Blu-ray optical drives, and custom processing chips specifically designed to handle audio, video, and other background services. In terms of new apps and services, Sony has launched the dedicated app PlayStation app on smartphones and tablets, making the devices a second screen to enhance the gaming experience. Sony also plans to launch the cloud game streaming service "PlayStation Now" (formerly Gaikai), which stores downloadable content and games on cloud servers. In addition, the "Share" button has been added to the new controller, which will allow users to watch streaming live and screenshots and record videos of other people playing the process.
