Computer thinks HD 6720G2 is HD 6520G?

I went to install drivers (AMD Catalyst) because I thought performance was slow in games. After the install device manager showed my graphics card as a HD 6520G instead of a HD 6720G2 like the computer is supposed to have. It also shows HD 6650M.

The computer uses the AMD A6 Vision APU. I'm just concerned as to why it seems to think my video card is downgraded after trying to update the drivers.

Help with how I could revert the changes made when installing the drivers so the computer recognizes it as a HD 6720G2
