Kotaku is reporting the PlayStation 4 is being codenamed “Orbis”. Development kits for Sony’s fourth generation device were sent out to “select developers” in January, with newer technology delivered after the 2012 Game Developers Conference.
The specs developers will be working with are AMD x64 CPU and AMD Southern Islands GPU (same as AMD’s high-end PC GPUs for 2012). The PS4 GPU will play games at a resolution of 4096×2160, which far exceeds the average HD television resolution with 1920X1080 pixels. In comparison the PlayStation 3 games output at 1280X720. The PlayStation 4 will also be capable of playing 3D games in 1080p, compared to PS3′s at 720p.
It is said the PS4 will not be backwards compatible with the current PlayStation 3 games. Orbis will have a built in feature that will prevent used games from being played. New PS4 games will be available on a Blu-Ray disc or PSN downloaded. If you have the disc, it must be locked to a single PSN account. Used copies will be limited to a trail mode, before they have to pay a fee to unlock/register the full game.
