Hi,
How can i know if it's GPU bound or CPU bound ?

I use rtx 3070 & 10700k
I dont have a lot of pc knowledge so i will very appreciate a rice explaining.

how can i check by myself ?
Is it the gpu/cpu usage ?
 
Every program/app/game is different. In certain you are GPU bound, in other CPU bound.

If we're talking about games, use MSI afterburner, play for 20 mins your game and then check logs of GPU and CPU usage. The CPU usage should be per core and not as a total.

If a core reaches 90+% for a significant amount of time then you are CPU bound.
 
If a core reaches 90+% for a significant amount of time then you are CPU bound.
That's a very rough estimate since lots of games run the cpu as fast as possible but drop a lot of frames and only use the most current one.

You have to reduce resolution and/or quality of the game and see if you get more FPS, that would mean the GPU is holding back the CPU, the CPU could run the game faster.
If the FPS does not increase (or not anymore) it means that that is the limit of the CPU ,or a limit of the game engine which is very common, and it is holding back the GPU.

As already stated you would have to do that for every game you are interested for, and as also mentioned, you do have a good matchup and don't need to worry.
