I am using ubuntu 22, with an i7 12th gen gpu with 16gb ram and Nvidia rtx 3060 gpu with 6GB vram.

While doing heavy tasks such as gaming I have observed in the activity monitor that only 2 CPU out of 16 ( mainly cpu5 and CPU 7 ) are being utilized to 100 percent whereas the other CPU hover near to 0.

I have also observed that the graph of CPU 5 and CPU 7 are almost mirror images, if CPU 5 is being utilized then CPU 7 goes down and vice versa, I am not sure why is this happening and why the other CPU is not being utilized.

This is not only limited to gaming though whenever I hear fans running or doing some task such as browsing I observe the similar pattern. I even tried the solution present here but it does not seem to solve the problem I think I am unable to add the image yet because of reputation so giving you guys with the link to image hope this helps 1

To check your cpus install stress:

sudo apt install stress

Then issue the command:

stress -c 16

assuming you have 8 cpus with 16 threads. Check your monitors now - all cpus should be on 100%

End the test with Crtl+c

Since you tested with "games": Applications that render heavily usually pass as much load as possible to your GPU.
