Mobile Intel Ivy Bridge CPU details leak, including new Extreme Edition, Ultrabook processors

Yesterday, we reported that product names and specs have leaked about Intel's upcoming Ivy Bridge desktop processors. Now information about their mobile counterparts has been revealed as well, including a new Extreme Edition chip and new CPUs for Ultrabooks.

Somewhat surprisingly, given its power savings on the desktop side, mobile Ivy Bridge retains the same TDPs as Sandy Bridge -- 35W, 45W, and 55W for standard-voltage processors, and 17W for what's now being called Ultra (as opposed ultra-low-voltage) chips. And like the desktop roadmap, there are no Core i3s on this initial list of mobile parts. All of the Ivy Bridge mobiles come with Intel's HD Graphics 4000, which supposedly promises 30 percent better performance than Sandy Bridge's integrated graphics.

The new high-end flagship, the quad-core Core i7-3920XM, runs at 2.9GHz (3.8GHz with single-core Turbo Boost) and comes with 8MB of L3 cache. Other quad-core, eight-thread Core i7 Ivy Bridges include the i7-3820QM (2.7GHz) and the i7-3720QM (2.6GHz), while the 2.9GHz i7-3520M is a dual-core, 35W processor. Two other 35W chips are the Core i5-3320M and i5-3360M, both of which are dual-core.

The first two Ultra Ivy Bridge CPUs are the Core i5-3427U, running at 1.8GHz (2.8GHz single-core Turbo Boost, 2.6GHz for both cores), and the 2GHz Core i7-3667U with 3.2GHz single-core Turbo Boost and 3GHz dual-core Turbo Boost.

VR-Zone reports that it's hearing a springtime launch for these mobile processors, though that may become clearer at CES if Intel officially reveals details about Ivy Bridge.
