This is normal.
What motherboard do you have? You have a feature that laptop have enabled in your motherboard's BIOS. It'll declock your speed like what you are seeing when you are idle, and will jump back to max clock speed whenever you load something.
The feature can be called C1E, Speed Step and probably more names that I forget.
I personally wouldn't worry about this. I like the feature.
