Intel Core i7 3960X (Sandy Bridge E) Review: Keeping the High End Aliveby Anand Lal Shimpi on November 14, 2011 3:01 AM EST
At idle, the 3960X's power consumption is barely discernible from the 2600K. Under load however, Sandy Bridge E can draw significantly more power. We measured 35% more power draw over a 2600K. The added power consumption makes sense. The chip has more cores and a larger cache, without introducing a more power efficient architecture or a new manufacturing process.
