A further feature of the Core i7-720M is the Hyperthreading-Technology. This technology supplements the four physical cores with four virtual cores so that the CPU is able to process up to eight physical threads at once. In applications optimized for parallel computation Hyperthreading can lead to a noticeable speed increase, though games will hardly profit from such technology. The maximum electrical consumption, at 45 Watts, isn't exactly low but there again the 774 million transistor chip...
