Intel's Sandy Bridge notebook processors will include five low-power processors for ultraportables, a roadmap slip has uncovered today. The range would start with three low-voltage Core i7 chips, the 2610LM, 2620LM and 2640LM. Two ultra-low voltage chips are set to make their start, Digitimes said, including the Core i5 2530UM and Core i7 2630UM.
