"Graphics hardware can rapidly drain a laptop's battery -- there's a good reason why many Ultrabooks ship with nothing more than basic integrated video. If Intel brings a new low-power graphics core to market, though, high-performance visuals and long battery life won't be mutually exclusive concepts. The experimental design boosts the voltage of those components it needs the most, letting it aggressively reduce the voltage of unused circuits; it can even put the entire core to sleep for brief moments. The result is a GPU that's 40 percent more efficient than what you'd otherwise get. The company isn't saying just what it will do with its discovery, but it notes that the part could either extend the longevity of a mobile PC or improve its performance without sapping any more energy. If you can eventually buy an ultra-thin laptop that easily  runs Crysis all day long, you'll know who to thank."^^<http://www.w3.org/2001/XMLSchema#string>
