According to Maximum PC, Intel recently revamped its official price list by adding four new ULV (ultra-low-voltage chips generally found in ultraportable notebooks) processors. The new additions feature three Sandy Bridge based chips and one Intel Celeron processor. The three new Sandy Bridge ULV CPUs include the dual core hyperthreaded Core i5 2557M with 3 MB cache running at 1.7 GHz, Core i7 2637M with 4 MB cache running at 1.7GHz, and the Core i7 2677M at 1.8 GHz with 4 MB cache. Utilizing Turbo Boost, the chips are able to reach 2.7 GHz, 2.8 GHz, and 2.9 GHz respectively. Further, the new Celeron ULV is the dual core Celeron 847 processor with 2 MB cache running at 1.1 GHZ.
The Core i5 2557M carries a pricetag of $250, while the Core i7 2637M goes for $289, and the Core i7 2677M has an MSRP of $317. You can see the entire price list here. The new Sandy Bridge based ULV processors are able to Turbo Boost from between 1.0 and 1.1 GHz depending on model, which should provide plenty of power for mobile devices while sipping battery power with a TDP (themal design power) of only 17 watts.
