Following initial reports from tech blogs Fudzilla and SemiAccurate, our sources have confirmed that mass production of the system's GPU will indeed begin by the end of 2012 but will not, however, be based on AMD's 7000 series Southern Islands GPU. Instead, the processor will be derived from the 6000 series, which was introduced last year. More specifically, it will be akin to the Radeon HD 6670, which offers support for DirectX11, multidisplay output, 3D and 1080p HD output. The chip currently has a market price of upwards of $79.99.

In real terms, the Xbox 720's raw graphics processing power is expected to be six times that of the Xbox 360 and will yield 20-percent greater performance than Nintendo's forthcoming console, the Wii U.
