Graphics hardware can rapidly drain a laptop’s battery. 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.
