A new powerful system architecture, social integration, and PlayStation Network combined with cloud technology
At PlayStation Meeting 2013, Sony Computer Entertainment officially introduced PlayStation 4 (PS4), its next generation computer entertainment system centered around a custom chip that contains eight x86-64 cores and a state of the art graphics processor. The Graphics Processing Unit (GPU) has been enhanced in a number of ways, principally to allow for easier use of the GPU for general purpose computing (GPGPU) such as physics simulation. The GPU contains a unified array of 18 compute units, which collectively generate 1.84 Teraflops of processing power that can freely be applied to graphics, simulation tasks, or some mixture of the two.
PS4 is equipped with 8 GB of unified system memory - GDDR5 is used for this memory, giving the system 176 GB/second of bandwidth and providing a further boost to graphics performance.
In addition, gamers can press the "SHARE" button on the controller, scan through the last few minutes of gameplay, tag it and return to the game - the video will upload as the gamer plays. Gamers can share their images and videos to their friends on social networking services such as Facebook. During live broadcasts, friends can make comments on the streamed gameplay and, if a gamer gets stuck on a challenging level, friends can offer health potions or special weapons when a player needs them most during actual gameplay.
PS4 integrates second screens, including PlayStation Vita (PS Vita), smartphones and tablets, to wrap gamers in their favorite content wherever they are. With PS Vita, gamers will be able to seamlessly pull PS4 titles from their living room TVs and play them on PS Vita's 5-inch display and dual analog sticks over Wi-Fi networks. A new application from SCE called "PlayStation App" will enable iPhone, iPad, and Android based smartphones and tablets to become second screens. Once installed on these devices, users can, for example, see maps on their second screens when playing an adventure game, purchase PS4 games while away from home and download it directly to the console at home, or remotely watch other gamers playing on their devices.
PlayStation Network will be combined with Gaikai Inc's cloud technology, so when a gamer sees a title of interest in PlayStation Store, they can immediately start playing a portion of the actual game - not a stripped down version of the game.
