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?

CPU-z can assist in detection. Another option is disassemble of the card from the fans, heat sink, etc. And verify the physical components vs. A known good source card.

You could run some GPU based benchmarks and compare results to other user submitted benchmarks to see if there's a massive deviation from the norm. Ymmv, unless the results you're comparing to have a similar entire system setup.

There's also nvidia profile inspector, can compare that with cpuz to point out any spoofed possible changes if they don't align data wise.
