Buying a mining GPU is an interesting one. There are several conflicting aspects to the aging of a GPU:
So IMHO, a mining card is likely a good buy IF the miner had half a brain and was running the card at low power limits. Likely less degredation than a intermittently used card by a gamer, EXCEPT for mechanical parts, but those are trivial to replace.
I'll probably grab an ex 3090 close to release of the 40 series. *shrug* It's definitely a gamble though.
- The time in use ages electrolytic capacitors, roughly halving the lifespan for every 5C:
- Even the worst hybrids caps are generally rated to 10k hours @ 105C
- Polymer caps (SP-CAP) are generally rated to 2k hours @ 105C unless you got for high-spec types, which is doubful
- The time in use ages silicon, where I don't know the lifespan impact vs. temperature for the Samsung 8Nm node, but temperature has a large impact that interacts with voltage.
- The number of power cycles has an effect on lifespan
- The number of thermal cycles has an effect on lifespan
- Time in use ages moving mechanical components, fans - big surprise right
