ryzen 2500u

I have a Hp Envy x360 13'' i tried playing some light games and experienced that the pc might throttle itself without being hot. i looked at the task manager while playing and the cpu goes from 20-50% but not much above that. no matter what resolution i play at. if it is at 800x600 or 1920x1080...

Sorry if this was asked earlier, but i couldn't find any thread about this. so here's my question. Does RAM speed matter that much in ryzen 2gen mobile processors as it does in desktop ones? The exact case is how much bottleneck will there be with ryzen 2500u and 2400 mhz memory
