Question AMD A10-7400P frequency drop

[eragonpower]

Hello, Is already almost an year that i've noticed that, when i start an application that require an higher load of the cpu, the frequency drops from 2.5GHz to almost 1.7/1.2 GHz. What's appening??
I've already tried to disable the Power saver, and to reinstall Windows from zero, and this Is still appening.
What can i do??
