Leaked tests show Nvidia's CMP 40HX mining card performing close to an RTX 3060

Don't ever buy a used mining card. Electronics do wear out from heat.
That's the common belief, but it might simply not be true. Two reasons.

1)
Miners tend to run their cards as efficiently as possible, rather than as highly clocked as possible. Since the efficiency curve drops like a rock the closer you are to max clocks, miners underclock and undervolt their cards to an optimal point. This means that despite the card running 24/7, it is running in a less "strained" state than if you were gaming. I do get that mining uses more of the GPU at any given time and generates more heat, but I don't see how that's an issue, because...

2)
Changes in temperatures are more damaging to hardware than high temperatures (within reason of course). If you run constantly at 70°C for a year, or if you cycle between 35°C and 70°C every day for a year, the latter will fail much earlier than the former due to shrinking and expanding of the components.
 
Why the f would I buy this is barely does 3060 non limited performance for 3070 prices, I rather get a 3060ti that does 60mh for 500, if I can find it in stock. and still have resale value afterwards. these go in the garbage after.
 
No, the fact remains that it's a used card that has been running 24/7 for months, if not for more than a year, the buyer will never know.

Indeed.... "tend".... that's enough reason to stay away from these cards. As for efficiency; an efficient GPU is a GPU that is idle. No, those guys push these cards, maybe not over-clocked, but they're running them at high speed, while I can ensure you that a lot of games aren't pushing the card to its max if the player sticks to 60fps at 1080p, still with 67% according to Steam stats the most popular resolution..

A GPU can handle a cycle just fine a few thousand times a year for years in a row, and who runs every game at 70°C? Mine seldom goes over 60°C. Secondly, gamers don't game 24/7. I'm pretty sure that a card running at 70°C 24/7 a whole year is more likely to fail. The fact that a CPU seldom fails while it's going it's constantly going up/down during usage, just proves that you're exaggerating the issue, which is not surprising considering you're a bit-miner, who doesn't want more and more people to know that they shouldn't waste their money on dumped mining cards, right?

First of all. I have no mining farm, no ASICs, and just one (relevant) GPU, which is an R9 Fury. And I don't even mine on it, because, where I live, electricity is expensive. I actually am patiently waiting for the next dumping of cards on the market to upgrade my graphics card, because we will not only get good prices, many new cards will be sold below MSRP.

And now that I think about it, I'm not interested in having discussions with people that make baseless personal accusations. So... That is all I have to say for now.
