Some more details of Core i7-2640M
The core i7-2640M, is the successor to the Core i7-2630M bumbing its base and the turbo frequency by 100 MHz . You should therefore exect a performance improvement of the order of 3%. Based on the second generation Sandy Bridge processor, Core i7-2640 is expected to appear in a smaller number of notebooks because of its higher price tag. ant performance with its integrated GPU. The integrated GPU of this processor take a quantum jump in performance as compared to the 1st generation core i7 processors. The GPU has a base clock of 650 MHz and with turbo, its frequency can ramp to 1.30 GHz.
