2 GPU Installed?

Hi I have just installed Zorin OS 16 in an old Intel i3 laptop which has AMD Radeon GPU.
when I run lshw I get 2 entries

  • Which one is really used?
  • How can I check if the GPU is really used?
  • How do I enable the GPU acceleration of Zorin?

Both are used.

Thanks @Bourne
How do I know which one is used and when? Can they be used both at the same time for the same task?

AMD Graphics are included in the Linux Kernel and managed automatically.
I prefer the Nvidia setup that allows user control over use and management.
