Command to list all processes and the CPU cores they're using and some other info?

I’m a noob using Linux, Tumbleweed, Gnome and Wayland. AMD Ryzen 7 laptop, CPU has 16 cores. 40GB RAM.

Is there a command that will give me a column list of all running processes name, PID number, core number and % of the core being used by that process?

I need to find out which specific process or processes is/are causing various cores to run at 100%. This is causing big slowdowns.

I can see which processes are using the overall CPU, but that is insufficient detail.

When one of my cores is pegged at 100%, the highest CPU using process will be at roughly 1%. Which is strange cuz one core at 100% presumably = 6.25% of the CPU.
