The title is the full description of the question. lspci & neofetch output.
I cant find the exact model of my GPU because the output from neofetch shows too many configurations. Which of them is correct?

I followed this link. The situation is very similar to that of mine but none of the answers helped.

If you feel to downvote the question, please leave out a comment where I can find additional info on the matter.
