Special Chinese Factories are Dismantling NVIDIA GeForce RTX 4090 Graphics Cards and Turning Them into AI-Friendly GPU Shape

The recent U.S. government restrictions on AI hardware exports to China have significantly impacted several key semiconductor players, including NVIDIA, AMD, and Intel, restricting them from selling high-performance AI chips to Chinese land. This ban has notably affected NVIDIA's GeForce RTX 4090 gaming GPUs, pushing them out of mainland China due to their high computational capabilities. In anticipation of these restrictions, NVIDIA reportedly moved a substantial inventory of its AD102 GPUs and GeForce RTX 4090 graphics cards to China, which we reported earlier. This could have contributed to the global RTX 4090 shortage, driving the prices of these cards up to 2000 USD. In an interesting turn of events, insiders from the Chinese Baidu forums have disclosed that specialized factories across China are repurposing these GPUs, which arrived before the ban, into AI solutions.

This transformation involves disassembling the gaming GPUs, removing the cooling systems and extracting the AD102 GPU and GDDR6X memory from the main PCBs. These components are then re-soldered onto a domestically manufactured "reference" PCB, better suited for AI applications, and equipped with dual-slot blower-style coolers designed for server environments. The third-party coolers that these GPUs come with are 3-4 slots in size, whereas the blower-style cooler is only two slots wide, and many of them can be placed in parallel in an AI server. After rigorous testing, these reconfigured RTX 4090 AI solutions are supplied to Chinese companies running AI workloads. This adaptation process has resulted in an influx of RTX 4090 coolers and bare PCBs into the Chinese reseller market at markedly low prices, given that the primary GPU and memory components have been removed.



Below, you can see the dismantling of AIB GPUs before getting turned into blower-style AI server-friendly graphics cards.



For assurance that these cards work, factories are stress-testing them after modifications in Furmark, 3DMark, and AI applications, probably running some smaller LLMs locally to test their compute capability. Indeed, this process could potentially brick a lot of AD102 GPUs if not handled with care, but the yields of this experiment are unknown to anyone outside these factories.

As much as I complain about NV's pricing policy, there's no denying the 4090 is a tremendous card. With that said, reading this story is like reading about a bunch of old masters paintings being chemically treated to remove some archaic and valuable pigment. It's a murderscene. Or it's body modding, Scav style in CP2077.

Technical question. How much time would a cyborg get on a single battery charge if fitted with an desktop RTX 4090 GPU?

That's just barbaric and wasteful. I doubt that the shortage of 4090's is linked to Nvidia clearing stock for Super, more likely it's just that they shipped everything to China.

Well it's at least a small surprise they're not being escorted directly from the factories, or maybe not o_O

Pretty sure if CCP wants these chips/parts they can get them almost any way possible, after all most(?) of them are "assembled" in China!

AI Friendly more like sensible sizes

There were 200W single fan cards, 1080/2070/3060Ti (no 4070 though lol)



A 4090 can simply be a double fan card then (assuming linear scaling between size and power, but see AFOX 4090 in thread)
Ofcourse they can be 2-slot, but then the majority of users would complain about noise.

Taiwan (technically not China) and other locations. Coolers maybe in China but not the chips.

With a range extender in the backpack, made from an old chainsaw and a car alternator, and running on iGPU 75% of the time, an entire day!

Finally a use Nvidia can be proud of! Cryptoscamming wad borderline illegal, so theh had to resort to appologies for catering exclusively to miners and promise to limit gaming cards to gaming exclusively (a promise they broke the second they released the LHR gaming cards).

But with AI they can fully support this worthy use of otherwise almost useless hardware - come on, gaming on a $2000 cards? And gaming in general?

Too bad the main customers seem to be from a country they shouldn't sell those cards to, but bussiness is bussiness, right?

Everything nvidia say is a lie and they still get away with it because the demand for its products is massive, Intel used to do the same and look what happened to them.

Not really "wasteful." a lot of the boards will get repurposed as 'Frankenstein' GPUs with chips ripped from faulty unrepairable laptops or anywhere they can source chips that havent been blocked from sale.

I really enjoy the fact that I didn't get totally ripped off on VRAM and performance when I purchased my RX 6800. I've got several games that blow right past 12GB of VRAM at 1440p.

I don't understand the usefulness of the great and costly effort of: making multilayer PCBs, equipping them with quality VRMs, transplanting chips, wasting some chips, thorough testing etc. All they can possibly save is some PCB surface area - 39% if the "end product " is an OAM module (102 x 165 mm = 168 cm2) or something similar, compared to the 4090 FE (135 x 205 mm = 277 cm2). But OAM (or SXM, or similar) modules also need precision, high density, high power connectors that can't be cheap.

Just transforming the GPUs into single-slot-wide, liquid cooled PCIe cards would seem a better way to achieve very high density in this case.

This is the new ETH crunch.
Only it doesn't affect gaming cards this time around (thank f*** for that!)

As good as the 4090 is for gaming, it's wasted in most games and unless you're playing the Nvidia-sponsored tech demo CP2077 with RT Overdrive and RR and DLSS3 Frame-gen you simply don't need one to get a top-tier experience in any game today, even at 4K resolution. There are plenty of alternatives from both AMD and Nvidia that do the job just fine without costing anywhere near $2000.

There are now plenty of games that don't even reach 60 FPS in 4K withpot DLSS upscaling with RTX 4090 - and that's without even turning the ray tracing on! You can argue that they are just broken, but we have them.

Also, VR would gladly take several times the processing power of RTX 4090...

Not sure about that, there's no Chinese brands which make/made the 4090 cards before this?
There are Chinese brands that, like all other AIB, buy the chips from NVIDIA/AMD and make the cards in China.

Sanctions.
They can't buy 4090 chips direct from Nvidia right now, but they can buy 4090 cards from Asia-based manufacturers not under the same sanctions as US-based Nvidia.
