Your CPU was idling. Modern CPUs have robust power-saving techniques. While idle, your CPU lowers its multiplier thus lowering its clock speed in order to save power. Try loading the CPU by running Prime95 and in CPU-z you'll see your CPU clocked at its nominal frequency.

Hi,

This is because of intel speedstep technologie.
The computer manage the cpu to your needs. If your on idle or do minimal task it slows the cpu to economize energy and less heat.
Disable it in bios but, unless you overclock, I suggest to keep it on.
