First mobile Pentium processors, based on Haswell microarchitecture, will be launching in September 2013. At the launch, there will be two models: Pentium 3550M for mainstream notebooks, and Pentium 3556U for ultrabooks. The latter one is an ultra low voltage processor with 2 CPU cores and 2 MB cache. The chip runs at 1.7 GHz, which should be equivalent in non-graphics tasks to 1.8 GHz Ivy Bridge part, that is comparable with Pentium 2117U. In graphics applications and games the 3556U is expected to be faster. The Pentium 3556U has 15 Watt Thermal Design Power, that can be considered much lower than 17 Watt TDP of the 2117U, if we take into account that Haswell ULV chips also integrate Voltage Regulator and a chipset. At this time we know only a few notebooks, that will be shipped with the 3556U. These include Packard Bell EasyNote TE69 (part TE69HW-29554G50Mnsk), Lenovo IdeaPad S310 and S410. The Pentium should be released in September 2013, possibly on September 1.
