As seen in a slide from VR-Zone, what makes this CPUs special is the fact that Intel will be dropping the thermal design power of its ULV processors for the first time in several years. While the current lineup is designed for at least 17 watts power consumption, the upcoming dual-core Core i3-3229Y, Core i5-3239Y, Core i5-3439Y, and Core i7-3689Y will be dropping to 13 watts. Intel will even be launching a Pentium dual-core that is rated at just 10 watts.
Don't expect performance monsters with clock speeds between 1.1 GHz and 1.5 GHz, but there are clearly interesting opportunities for innovative Ultrabook designs and we would be surprised if those CPUs did not end up in a microserver design, which calls for CPUs that consume less than 15 watts. These specific Ivy Bridge processors will also come with a technology that will allow system vendors to limit the TDP of the CPUs even further (cTDP). The i-series will then run at 10 watts, and the Pentium at 7 watts.
All five new CPUs are expected to launch in Q1 2013.
