1. please update your PCI ID database with:

sudo update-pciids

2. And use the following command in your terminal:

lspci -nn | grep '\[03'

You will see the model name of your graphic card. If it's ambiguous, you could search the PCI ID (something like [10de:11bc]) on the Internet for the corrent model name
