how fast would it be for those i7-720qm(1.6ghz) in comparison for those laptop c2d with higher clock..let say 2.5ghz in terms of rendering(3dsmax) im aware of i7 for dekstop have highers clocks(let say of the i7 860 at 2.8ghz) will outperform(@rendering) c2d procs(let say 3ghz).but im curious how will these mobile i7-720 with a lower clock speed compared to those of c2d with higher clock lappy @ 2.5ghz perform in 3dsmax rendering.
