Laptop step into the stage of using Core i7 chip

Core 2 Duo is currently the most popular chip for laptops, but the new Core i7 "Clarksfield" platform is beginning to penetrate the laptop market .

In June 2009, Intel announced that, along with the arrival of Core i3, i5 and i7, older brands like Core 2 Duo and Core 2 Quad will gradually disappear. The Core i7 series for mobile devices has three characteristics that make it different from the Core 2 Duo.

The first is an integrated memory controller, which has appeared on AMD chips for a long time but is now included in Intel products. This circuit makes the data exchange between the computer core and memory faster than when the components are separate on the circuit board.

Secondly, Turbo Boost acceleration technology automatically adjusts each individual core clock to suit the processing needs to improve performance and extend battery life.

In addition, Hyper-Threading technology provides two threads per thread, which can double the number of tasks a microprocessor can execute.
