is it normal for some of my cpu clock speeds to downclock to 4499mhz when gaming?

  I was under the impression that its supposed to stay turbo'd at 4.7mhz all times when gaming. I was previously power limit throttling but not power limit throttling anymore after increased pl1 limit but i am edp limit throttling because I have pl2 set to 193A. Others tell me this is normal behaviour. Average idle temps are 35c average gaming temps are 65-75 spikes in mid 80s are rare. I literally wasnt able to catch it with my eyes watching the msi afterburner cpu clock speeds reported the while time i was gaming

That's normal, only a few cores hit the boost frequency.
