We recently took a peek at what Intel saves for desktop Ivy Bridge processors, but now the VR-Zone got information on the mobile line of components from Chipzilla. The thing seems to be good, starting with the energy consumption: while the conventional chips will have voltage of 35W, 45W and 55W, the ultra low voltage cairo from 25W to 17W.

In terms of power, the regular consumer line ranges from a Core i5 dual-core 1.6GHz to a Core i7 quad-core 2.9GHz, a significant gain over the Sandy Bridge line. The low consumption processors, predestined to appear in future MacBooks Air, include a Core i5 of 1.8GHz and a Core i7 of 2GHz, both with turbo that can take them up to 2.8GHz and 3.2GHz, respectively.
The release dates for these chips are April (for quad-core) and May (for dual-core) next year. It seems like a lot, but that time passes quickly. (Repeat a thousand times while waiting.)

O MacRumors now highlighted another cool novelty of these Ivy Bridge chips: they will support up to three independent monitors, including the laptop itself. That is, future MacBooks Air (as well as MacBooks Pro 13 ?, which do not have independent graphics chipsets) with these processors will be able to work together with two Apple Thunderbolt Displays, without problems.
