Old because they're mostly used, repurposed crypto mining rigs, according to the article.
that's just called "used", my 1060 is "old".
I was clarifying that 'old' was not a descriptor of its age (it's a very modern GPU), rather a description of its potential wear and tear; so 'old' as in beat up.
FYI, LTT did a video showing ex crypto cards are totally fine. But let's keep that between us so the second hand market for those cards keeps low prices.
They can be fine. If they were properly undervolted and cooled. It's still a gamble.
After the last controversy around him, I'd take everything they release with a huge mound of salt.
Linus Media Group's main goal is to maintain their break neck schedule of releasing content, not to ensure 100% accuracy or that they've properly listed all caveats. Not to say that they don't care about accuracy, but that it is greatly eclipsed by their release schedule.
That was my first thought, they are only last gen guys! And easily comparable to the top of the line in the current gen!
With 20GB?! I'd take that over a 4070 or even 4080 any day
At least having those GPUs training neural networks is vastly preferable to having them mining Bitcoin.
GPUs havent been mining bitcoin for a long time now. Probably almost 10 years.
The last big coin mined by GPU was ethereum but that stopped last year
I'm never going to be able to afford an upgrade.
What card do you have?
1080ti. Still strong but starting to show it's age with newer games and AI stuff.
If youβre not doing huge models a used 2080ti can be picked up on eBay for 300 ish bucks which is pretty capable (best price to performance cuda core count I think)β just a little lacking in ram for huge stuff.
I use it for mostly gaming, AI is just a bonus. I'm looking for a big upgrade if I can ever afford one.
1080 ti is still a beefy card, about the same performance as a 3060 ti / 4060, just without the AI core shenanigans and more VRAM - not bad for a 6 year old card. I recently updated from a 1060 to a 3060 ti, which gave me roughly 50% extra performance, you'd have to grab a 4080/4090 to do the same. But yeah, not fast enough anymore if you do 4k or high hz stuff.
At this point I'm just waiting a few more generations. I donβt think there going to be reasonably affordable any time soon.
I could really use a 20g 3080 in my gaming pc. How do I buy one?
Make a tik tok, they find you.
Call China
Aside from anything else, the cooler looks spiffy. Not an over-the-top RGB monstrosity, and it's obviously designed to be compact.
The coolers work well, but at the cost of noise. under any gaming load they are exceedingly noticeable. The classic use case for this form factor is often servers, where noise doesn't matter. you also see these on more professional cards, but their whole power budget is often under 100W, so remotely the same category.
what is the appeal of blower-style cooling?, i always heard about it being worse for cooling
Blower fans are better if you want a bunch of cards in one system. Open air coolers dump too much of the hot air back into the case and are usually thicker. For non-gaming loads it's frequently better to have more cards at less than max speed.
They're really only worse in the sense that they can be louder. In a datacenter/mining rig/etc where you don't care about noise at all, they're pretty much the best solution to cooling a large amount of cards as they blow air out near the outputs instead back into the rack.
This is the best summary I could come up with:
Repurposed batches of "RTX 3080 20G AI" cards featuring blower-style coolers and with 20GB GDDR6X are being spotted in large quantities over in China, stored and sold via AliExpress.
These are yet another attempt to work around U.S export controls that now prohibit the sale of the fastest data center and consumer GPUs to China and other countries.
Prolific leaker I_Leak_VN also found many of these RTX 3080 20G AI blowers in warehouses via the Xianyu app, a Chinese-based used goods e-commerce website owned by Alibaba group.
LLM (Large Language Model) workloads greatly benefit from more VRAM, and there are other offerings showing repurposed RTX 3080 Ti 24GB GDDR6X cards.
Necessity is the mother of invention, and we're now seeing Chinese retailers repurposing RTX 3080, 3090, and 4090 "consumer" graphics cards into AI accelerators to at least partially work around the U.S. sanctions.
Earlier, these GPUs were sold for dirt cheap as miners wanted to get rid of them quickly to recover some of their investment.
