PlayStation 4 is the fourth game console of the PlayStation model and is part of the eighth-generation video consoles. It was officially announced on February 20, 2013 at the PlayStation Meeting 2013 event, although the console design was not presented until June 10 at E3 2013. It is the successor to the PlayStation 3 and competes with Wii U and Nintendo Switch and Microsoft Xbox One. It was launched on November 15, 2013 in the United States and in Europe and South America on November 29, 2013, while in Japan it was on February 22, 2014.
Moving away from the complex architecture used in the Cell processor of the PlayStation 3 game console, the PlayStation 4 features an 8-core AMD processor under the x86-64 architecture. These x86-64 instructions are designed to make video game development easier on the next-generation console, which attracts more developers. These changes highlight Sony’s effort to improve lessons learned during the development, production and launch of the PS3. Other notable hardware features of the PS4 are that they include 8 GB of GDDR5 unified memory, a faster Blu-ray Disc drive, and custom chips dedicated to audio, video and background processing tasks.
Among the new applications and services, Sony launched the PlayStation App, allowing those with a PS4 to convert smartphones and tablets into a second screen to improve playability or external keyboards for more convenience at the time of writing. The company also planned to debut with Gaikai, a cloud-based gaming service that hosts downloadable content and games. By incorporating the “Share” button in the new controller it makes it possible to share screenshots, trophies, purchases or videos at any time on pages such as Facebook, Twitter and stream what is played and watch that of other friends on Direct from Ustream or Twitch, Sony planned to place more emphasis on the social game. The PS4 console on the first day of its launch sold more than 1 million consoles only in the United States. At the start of its press conference at Gamescom 2014, Sony announced that it had already sold more than 10,000,000 PlayStation 4 units in the world to end users. It is designed for extensive integration with PlayStation Vita.
