How to identify "legit" GPU (reddthat.com)

Hello,

I recently bought a used 3070 TI online, and thought I should come here to ask for some advice. The GPU I have currently I bought new from a retail store, so I didn't have much need to verify it.

I am aware there are resellers out there with more shady interests, and sometimes "hack" a gpu chip to show up as, for example, a 3070 TI when it is really a [ insert any other inferior gpu here].

My question is, how do I test this 3070 TI to ensure it is, in fact, a 3070 TI and not something pretending to be one. My best guess is to run a benchmark and compare my scores to others with similar hardware, but there's got to be a better way?

GPU-Z can detect some reflashed GPUs, not sure to which extend. This in combination with your benchmark idea should do the trick. Or you take it apart and look up the markings on the die.
