Not all Core 2 duo in laptops have bigger L2 cache
Core 2 duo T5200, T5500 and T5600 have 2MB L2 cache which is the same as Core duo
Core 2 duo T7200, T7400 and T7600 have 4MB L2 cache.
Also, Core 2 duo doesn't have faster clocks. The clock speed in Core 2 duo ranges from 1.6GHz to 2.33GHz, the same thing for Core duo (except for "low voltage" or "ultra low voltage" versions)
