There is literally no information. - was it actually the same GPU? - was the exact same system used (fresh install, same version, same drivers etc.) - same bios and microcode? Intel took quite a hit from Spectre meltdown - was the thermal paste replaced? - was the GPU undervolted and cooled well?
Electronics do not just 'wear out' or slow down over time. Electricity is electricity, and as long as there's no physical damage or corrosion to the components it will always perform as it was designed. This is because there are no moving parts with the card itself. The cooling system however was likely never cleaned properly or the fan bearings have worn out, both of which would reduce its effectiveness and lead to the card thermal throttling due to higher temps. Modern electronics are really super reliable, and performance tends to be affected by either software advancing beyond its capabilities or issues with moving parts it relies on to operate, which DO wear out due to their nature.
Just another clickbait article. Sure sign of sinking website.
As for article. Of course, because mining card has cooling issue. Very likely it needs thermal paste replacement. But basically what us happening is thermal throttling, meaning card clicks down to stay withing temperature target. And instead of replacing paste and actually figuring things out to our out educational piece, it seems like author was way too much in hurry to cash in on clickbait. A good site would take article like that down, because they value their regular visitors and audience more than burst you get with clickbait. I guess not this one. Just saying.
As for mining cards, they are safe purchase for reasonable price, especially if you can get picture of mining rig and can see that cards were spaced nicely. Miners will usually even undervolt them so they don't run too hot. But there is no harm in asking about it. Also always be prepared to change thermal paste on used cads. It could be fine, but I would do it just in case anyway.
But even with mining those cards will still last you for years to come. Unless you are looking for card you will keep more than 5 years, it will be fine. And as long as price is right, that is non issue.
Also you can get same with used cards sold by gamers. You never know how well cooled and maintained card was there either.
This is so hilarious...the one on the left is running in the mid 50Cs and the one on the right is in the 70s....nothing about this video is legit, it's a tailored LIE.
You mean they didn't do the minimum of reapplying thermal interface material after 1.5 years of abnormally heavy usage and then made a video about how it performed like no one had done the minimum to replace the TIM? My god, what a ducking revelation.
It's interesting to see how delusional people keep quacking about thermal paste like broken records.
Maybe one day you'll wake up and realize your average buyer CAN'T DO THAT BECAUSE THEY DON'T KNOW HOW. Yeah it's pretty hard using our brain i know.
Not only is that the responsibility of the miner to make sure the card is cleaned and repasted before sale, but it is also the miner's responsibility to warn the buyer that the card has NO warranty. As repasting VOIDS any warranty for almost all companies.
The video demonstrates why the average gamer should not trust or buy from a miner. YOU GET WHAT YOU PAY FOR AND IF YOU PAY BELOW MSRP FOR A GPU YOU GET A BELOW MSRP QUALITY.
This is straight up not true. The 2080ti wasn't even cleaned. A dirty heatsink could absolutely throttle that much performance out if the card on its own.
