The video chip integrated in the Sandy Bridge chip will be twice as fast?

According to Fudzilla, Intel announced a great news to their closest partners. The graphics chips which will be integrated into the future architecture Sandy Bridge planned for in one year will be twice as powerful as those currently installed in the processors Arrendale and Clarkdale. We do not know if Intel will make a real effort to modify their architecture or if they will be satisfied to benefit from their engraving in 32 nm and to increase the frequency significantly.
At this rate, and if Intel continues to double the performances of its video solution every two years, one will be able to play Starcraft II in the native resolution of an Apple portable in ten years time.
