Intel Core i7 for laptops(i7 4核 For NoteBook 在2010年之前)

quad-cores based on a 45nm process, with 32nm dual-core models following in early 2010...

...1.73GHz i7-820QM flanked on both sides by the 1.6GHz i7-720QM and the top of the range 2GHz i7-920XM.

Unlike their Core 2 Quad predecessors, all four cores boast Hyper-Threading; a move that allows the processors to handle as many as eight separate threads at once...

...if two or more cores are sitting unused, and the processor isn’t running too hot or drawing too much current, Turbo mode kicks in and ups the speed of the remaining cores. For the i7-820QM, this can take the stock speed of 1.73GHz up to a maximum of 3.06GHz, while the i7-720QM and i7-920XM push up to 2.8GHz and 3.2GHz respectively.原文：：
