How can I check the performance of an AMD Radeon GPU on Ubuntu 20.04?

I want to check whether my AMD Radeon GPU performs close to the manufacturer's indicated performance.

How can I do this?


You can install the command line utility "radeontop" to check the status of radeon graphics cards. You can install it using sudo apt install radeontop and run it using sudo radeontop

Edit, removed parts that somebody removed from question.
