Given GNs other coverage its a bit odd for them not to mention why someone would bother to make a 48 GB 4090. Or the whole side business of these "repair shops" of removing cores for sanction busting AI cards, reassembling the now worthless PCB with the cooler and scamming some unsuspecting customer that thinks they are getting a deal.
If the cards were legally acquired in the first place, I don't see how they (the shop) have any moral reason not to upgrade the cards however their customers want. It isn't their laws that prevent high memory cards. And the appeal of this is not just limited to sanctions limited countries. The prices for these modified cards are wildly cheaper than any vaguely equivalent card that and video will allow to be sold from an authorized OEM.
Five for one would love to be able to do that sort of upgrade work and offer it in the Continental US.
It is true that they did not entirely specified what happened to the waste boards here. Clearly somebody who is stripping parts is then reassembling cards and selling them on eBay or other places. I hope it is not this shop, but clearly they didn't even try to disclaim that behavior. I'm not saying they didn't disclaim it because they're guilty, it could just have not come up.
Generally there are a number of valuable components on the waste boards which can be parted out, and often kept on-hand for other repairs. Each of the chips on those boards are valuable for future repairs, and (in the USA at least) often quite difficult for repair shops to obtain. Here[0] is an example of such a chip from a MacBook Pro - it's a proprietary, custom Apple component so generally you can only obtain them through salvage.
I don't know if this shop sells any of their scrap into the scam industry, but I bet they'd have a white-hat market available for a lot of it.

I'm either particularly ignorant or this claim has some inconsistencies. My understanding is that you cannot "remove cores" from a GPU. The titular RTX 4090 (Ada Lovelace) comes with 16,384 CUDA Cores. At face value, it sounds like you're saying that Brother Zhang's repair shop uses some nano-technology tools to open up the Ada silicon itself and then somehow disable or destroy or dissect the silicon to reduce the core count. And then they sell these reduced core counts GPUs (???).
That's obviously preposterous, but I'm having trouble steelmanning this to re-construct your actual meaning.
Okay so 'stefan_ is arguing that the board which now has no GPU at all and is completely non-functional then gets sold to unsuspecting consumers? In that case, why would the scammer sell the 4090 board at all? At that level of fraud, the scammer could just as well send a circuit board from an alarm clock, or a brick. How does this behavior reflect back on Brother Zhang's shop at all?
So far, everyone's concepts have felt pretty half-baked. Perhaps someone could point me to some actual reports relating to this topic which go into real detail about allegations around how these repair shops contribute to fraud. I'm not having a lot of luck engaging here, but maybe I'm just a bit dim-witted.

Plausible deniability. With a real-looking GPU, the seller can always fall back on user error, bad PSU, driver issue, PCIe slot problem etc.
The buyer may even doubt themselves at first and spend time reseating the card, reinstalling drivers, swapping cables, or testing another system. By the time they're confident it's not their fault, the return window or dispute period may already be gone.
None of that works if you send a brick or an alarm clock PCB - the fraud is immediately obvious.
For that kind of scam, all you really need the cooler, which are often parted out for legit reasons (watercooling, replacements, probably some specialized high-density and rackmount plays) and may be available as a spare or "second-shift" offering.
It would probably be easy to produce a PCB that's the right size to fit a 4090 cooler, but just contains 90 cents worth of random SMD parts. And you can produce them in quantity when you want them rather than relying on an erratic supply of stripped "real" PCBs.
The people running YC and their entire social circle voted for this. Half of them are still riding the grift. Now they are all practicing for their Persilschein.
It's amazing, before we even had ChatGPT, GitLab was building so much endless slop halfbaked crap in their pursuit of ever more "enterprise checkboxes". Now they have slowed right down, no doubt collapsing under the escalating maintenance weight of all the nonsense that was created, like the canaries in the vibe coding mines telling us of impending doom.
Now you go to their blog, theres a banner at the top announcing "GitLab Agentic AI whatever is GA (GENERAL AVAILABILITY)" and you try to click it its literally a fucking 404 not found. That's the level of their stability and quality. Try it for yourself:
> The maximum legal speed of the vehicle would be limited to only 15 miles per hour (24 km/h); it could not weigh any more than 60 kilograms (130 lb), including the battery; and its motor could not be rated at any more than 250 watts.
It's interesting that these are still essentially the regulations for e-bikes in the EU today, I guess slightly relaxed (25km/h, 250W average only but can peak higher).
They weigh slightly more than a similar ICE vehicle. And why would drafting a big rig increase tire wear? The problem I mentioned was that EV drivers frequently drive more aggressively because it's intoxicating to be able to silently dust basically every other car on the road that isn't another EV. Those people do have tire wear issues :). And they're not drafting a big rig...
It's crazy how bad the interface it is. I'm generally a fan of the model performance but there is not a day where their CLI will not flash random parts of scrollback or have a second of input lag just typing in the initial prompt (how is that even possible? you are not doing anything?). If this is their "premier tool" no vending machine business can save them.
It's employing so may people who specialize in Salesforce configuration that every year San Francisco collapses under the weight of 50,000+ of them attending Dreamforce.
And it's actually kind of amazing, because a lot of people who earn six figures programming Salesforce came to it from a non-traditional software engineering background.
That sounds a lot like "LLMs are finally powerful enough technology to overcome our paper/PDF-based business". Solving problems that frankly had no business existing in 2020.
The idea that a nation state could not make use of the hundreds of nuclear weapons in its territory is just absurd. It's sillier than the people that think disk encryption will spare them the crowbar to the face. Beyond the whole chauvinistic idea that it was "Russians" that built them in the first place.
