The next-gen Xbox's GPU will derive from 2011's AMD 6000 series, similar to the Radeon HD 6670, which supports DirectX11, 1080p HD, multi-display output and 3D, IGN reports, citing sources close to the project. Mass production of its GPU will begin at the end of 2012, IGN says, with a full-console launch scheduled in October or November 2013.

With these specs, the next Xbox will have six times the processing power of the Xbox 360 and is expected to support performance 20 times greater than Nintendo's Wii U, which is using the R770, a chip that is competitively stronger than the GPUs of both the Xbox 360 and PS3.

Previously uncovered Microsoft resumes listed gesture and voice input, which suggests some form of Kinect integration will be present in the coming Xbox model.
