You could physically look at the card installed. The serial number sticker should state everything.
I don't believe any software can tell you the specific model within a brand. Most can only tell you the GPU chip at the core (eg. GTX 1060) and the BIOS vendor, potentially brand.
I don't believe software is going to tell you that you have (for example) an ACX3.0 model etc. Clock speeds etc can help you determine, coupled with the other known factors.
