Documents from Intel Corp. allegedly seen by Expreview web-site reportedly mention that Intel Core i7 processor delivers 52% speed improvement in 3D games, 41% higher performance in media encoding and editing applications as well as 38% greater 3D rendering speed when compared to Intel Core 2 Extreme QX9770.

Intel Core i7 965 is a premium class Nehalem-micro-architecture microprocessor for desktops that operates at 3.20GHz. The Core 2 Extreme QX9770 is Intel’s top-of-the-range CPU at the moment at that also works at 3.20GHz. If the information regarding performance improvements is correct, then it means that the new micro-architecture in its first implementation provides roughly 52% more performance at the same clock-speed compared to currently used Core 2 micro-architecture.
