17W TDP, impressive clocks
Intel has updated its official price list and officially introduced four new ultra-low voltage Sandy Bridge processors with a 17 watt TDP.
The range starts with the Mobile Celeron 847, a 1.1GHz dual core processor with no multithreading and no Turbo feature. It has 2MB of L3 cache and it sells for $134 in 1k units.
Moving along to the more interesting models, the Core i5-2557M packs two cores with multithreading and 3MB of L3 cache. It runs at 1.7GHz, but under Turbo it can go up all the way to 2.7GHz. The price stands at $250.
The Core i7-2637M and Core i7-2667M are also dual-core parts with four threads and they feature 4MB of L3. They are clocked at 1.7GHz and 1.8GHz respectively, but under Turbo they deliver 2.8GHz and 2.9GHz, which is rather impressive for 17W chips.
