A leaked Intel image late last year seemed to detail plans to reduce the power consumption of the existing Ivy Bridge chips down to a 10W TDP. Intel has finally confirmed that these chips are coming and they say they will be talking more about these at CES 2013, where at we will get the full scoop.

"Limited SKUs" of Ivy Bridge will be rated at 10W, which means it will be able to use less than that during most use. This is an important metric as current Ivy Bridge CPUs are rated only as low as 17W, which is 70 percent higher. These new low-power chips will enable Ivy Bridge chips to be used in smaller and lighter devices, such as tablets and super-thin Ultrabooks.

The current 17W crop of chips are already used in the MacBook Air and many different Ultrabooks. A lower-powered chip will enable longer battery life in these same machines. Haswell will also be talked about at CES because it is coming later this year and will offer even greater power savings.
