Details on Intel's Ivy Bridge mobile CPU lineup may have leaked, just three days after supposed information on its desktop versions surfaced. According to alleged internal documents published by VR-Zone, Intel is doing away with the low-voltage variant seen in Sandy Bridge, condensing the product line down to just standard voltage and ultra-low voltage (think ultrabook) versions. Intel now allows for programmable TDP in its mobile processors, making the low-voltage products redundant.

The standard-voltage line will bring a modest speed bump to laptop users, with options ranging from a 2.6GHz dual-core i5 to a 2.9GHz quad-core i7 "Extreme Edition." As for the chips likely to end up in next year's deluge of ultrabooks, Intel will be launching two different models: a 1.8GHz dual-core i5, capable of 2.8GHz single-core turbo speeds, and a 2GHz dual-core i7, with a single-core turbo maximum of 3.2GHz. As for i3 options, they're not to be seen on the roadmap whatsoever, though whether this is a temporary omission or a permanent choice is still unclear.

All models across the lineup feature Intel HD 4000 graphics and 1600MHz DDR3 RAM, with the quad-core chips listed as being available in April. The rest of the lineup will follow in May. We expect to have official, honest-to-goodness details for you after Intel's keynote this January at CES.
