HTOP

How to install
open your Terminal (Ctrl-Alt-T ) and Type

This will show what you are asking. .

1Why is this the accepted answer when an earlier answer provided a faster builtin solution? This answers questions that weren't even asked. May 16, 2018 at 5:21

@deanresin I completely agree with you. But if you know how to use htop then you will know how to monitor each CPU core performance. Thank you.– Raja GMay 16, 2018 at 9:50

If
F10
does not quit htop but shows some menu, as prompted at bottom, pressq
orctrl - c
to exit. Sep 29, 2018 at 15:33
In your dash i.e. pressing super
key search for system monitor application.
If you are comfortable with command line there are tools like top
and htop
where cpu usage can be viewed as well.

1gnome-system-monitor is not installed by default on Ubuntu 18.04 anymore for some reason, you need
sudo apt install gnome-system-monitor
first: releases.ubuntu.com/18.04/ubuntu-18.04.3-desktop-amd64.manifest Sep 18, 2019 at 12:28
As said in previous answer you can use system monitor which is the best tool. If you want more information you can try some commands on terminal
top
- its a command to see all the processes and their CPU usage. Just read the screen carefully and you would find lot of other useful information there.
you can press Ctrl+c to close it.
Or you can also try
cat /proc/cpuinfo
- for other information about cpu
