Before you spazz about the source joystiq is very reliable. Moreso than kotaku imo.With these specs, the next Xbox will have six times the processing power of the Xbox 360 and is expected to support performance 20 percent 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.
Mod edit: THIS IS STILL RUMOR AT THIS POINT SO STOP FREAKING OUT LIKE IT'S 100% CONFIRMED.
No its not, no where did it say rumor.
