Intel plans to launch its Core i7 architecture on the mainstream desktop this fall with three processors, a leaked roadmap shows when combined with earlier leaks. The 3.2GHz Core i7 Extreme 965 will ship in the fall as the chipmaker's gaming-oriented quad-core processor and should be accompanied by regular 2.66GHz and 2.93GHz versions (Core i7 920 and 940) at the same time.
