The existence of a Chinese company that has modified the RTX 5090 for AI processing has come to light, and they have acquired a large number of RTX 5090s that are supposed to be prohibited goods, removed the GPU and transplanted it to a dedicated board.
Due to US export restrictions, it has become difficult to obtain high-performance semiconductors for AI in China. It has been revealed that there is a company in China that is modifying NVIDIA's flagship graphics board for general use, the GeForce RTX 5090, for AI use. A video posted on the video site Bilibili shows the entire process of removing the GPU die from the GeForce RTX 5090, which is supposed to be subject to export restrictions, and installing it on a custom board.

RTX 5090s get ready to blow with AI-focused makeovers in China — industrial production lines transplant GPU and memory from gaming cards onto server-ready PCBs with blower-style coolers | Tom's Hardware

A pile of INNO3D GeForce RTX 5090 boards in the workshop. Looking at the packaging, we can see that these boards are not the GeForce RTX 5090 D, a performance-limited version for China, but the full-performance GeForce RTX 5090.
We also have a large stock of Palit boards.
There are a lot of boards equipped with GeForce RTX 5090, which should be hard to come by.
Boards equipped with GeForce RTX 5090 will be checked for functionality before modification.
Only those that pass the test can proceed to the modification process.
The first step in the mod is to disassemble the board to remove the GeForce RTX 5090 GPU die.
The parts are disassembled one after another, and the circuit boards pile up.
The removed boards.
There are a lot of circuit boards lined up.
Next, remove the GPU die from the board.
I was able to remove it.
The removed GPU die is then transferred to a custom board for the modder. This is the board being made.
The wiring on the board looks like this:
Precision machinery is used to attach the GPU die to the substrate.
Once the GPU die is attached, a high-definition sensor is used to check the product.
Boards with GPU dies attached that have passed the inspection.
A custom-designed exterior is attached to the board.
Back plate also included.
This completes the modified board equipped with GeForce RTX 5090.
Completed boards are production tested before shipping.
Boards that pass the test are boxed up, with the words 'Ready For AI' written on the package.
The finished product and the package lined up.
The main features of the modified GeForce RTX 5090 board are its thinness, fitting into two slots, and its external exhaust.
A typical GeForce RTX 5090 board has an internal exhaust cooling mechanism that exhausts heat inside the case, which is disadvantageous for installing multiple graphics boards in the case. On the other hand, the modified version has a structure that dissipates heat outside the case, so it is suitable for the AI workflow of 'equipping a large number of graphics boards in one machine and performing parallel processing'.
