Cpu speed (GHz) decreases by 0.5 GHz when I play Overwatch, even when on a high performance power plan

I have had this issue for a while now and have searched online for many fixes ( high priority, deleting certain files, using a high performance power plan and even turning all game settings to the very minimum) but I still cannot get a stable frame rate. One second it will be 70 fps, the next it will be 40 and it is starting to affect my gameplay a lot more nowadays.
I used a 64 bit windows 10 computer with 8GB of RAM and the specs are: Intel Core i5 - 52000 CPU @ 2.20 GHz. I understand this is not a gaming computer or anything like that but seeing as I won't be able to get a new one any time soon it would be really helpful if anybody could come up with a solution for me :)
Last Note: Just in case it matters, the place where I viewed the speed of it is task manager performance tab
 
Solution
It can't sustain that speed for long without reaching it's thermal limits with two threads or more (which is what overwatch uses)

This is entirely normal behavior for your CPU and is to be expected.

We are talking about the i5 5200U correct?
