In both cases, your CPU can run slightly faster than its specified frequency, typically when one of its cores is running a CPU-intensive process, and the others aren’t. On your Core 2 Mobile system, this was provided by Intel Dynamic Acceleration; on the Core i7, by Turbo Boost.
The exact details vary from one processor to another. Earlier CPUs could only boost one core, but nowadays multiple cores can be boosted. The CPU ensures it stays within a certain power and thermal envelope.
