Intel is planning on releasing three new 32nm dual-core CPUs for ultrathin notebooks in the first half of next year, Digitimes reported on Thursday. Their notebook manufacturing sources claim the 1.2GHz Core i7-640UM, 1.06GHz Core i7-620UM and 1.06GHz Core i5-520UM would be aimed at the high- to mid-range ultraportable markets and replace the current 1.6GHz Core 2 Duo SU9600. As Core i7 models, the two faster chips would support Hyperthreading and sometimes give these chips the behavior of quad-core models.
