The power consumption levels for the Core i5 750 processor and the new P55 chipset are very impressive. At idle our Core i5 box consumed 106 watts, while increasing to 198 watts under load. Compared to the equally clocked Core i7 920, the Core i5 750 is far less power hungry. Compared to older platforms, the Core i5 750 used less power than even the Core 2 Quad Q9650 making it the most efficient platform and processor by far in our tests.
