What are you talking about?

The i7 2670QM is a quad core CPU, 2 thread per core (8 thread in total). Default @ 2.2GHz for all cores and turbo boost is 2200MHz+(6/6/8/9)x100MHz for 4/3/2/1 core, that is to say turbo boost of 2.8GHz for 4 core, 2.8GHz for 3 core, 3.0GHz for 2 core and 3.1GHz for 1 core.

Your i7 will beat the C2D CPU at the same GHz (2 core C2D vs 4 core i7, as well as better efficiency of Intel Core i series CPU compared to Intel Core 2 series CPU).
