In addition to AI accelerator cards being banned from China, the same goes for high-end workstation graphics cards from NVIDIA and AMD. As a result, many special editions have appeared, such as the latest RTX 6000D, which is based on the RTX PRO 6000 Blackwell. However, according to anecdotal reports,There is no market for this card in China, and no customers want it, which is really embarrassing.

Recently, Bilibili UP owner "Ji Shu Dog" got an RTX 6000D, dismantled it to explore its secrets, and modified it into a water-cooler. Let's take a look.

The appearance of the graphics card is exactly the same as that of the RTX PRO 6000 Server version.Fanless design, a system fan is required to assist cooling.

The measured maximum power consumption of the entire card is just over 400W.

There are alsoA four-pin 3D stereo sync interface, a frame lock/sync interface, the tail is a 16-pin power supply interface.

RTX 6000D is also a TSMC 4N process and GB202 chip.The number of CUDA cores has been reduced from 24064 to 19968, the number of Tensor cores has been reduced from 752 to 624, and the number of ray tracing cores has been reduced from 188 to 156, all reduced by 17%.

The core acceleration frequency has also dropped from 2617MHz to 2430MHz, an amplitude of 7%.

The video memory has also been slashed.512-bit 96GB GDDR7 changed to 448-bit 84GB, and the bandwidth response dropped from 1.79TB/s to 1.57TB/s, a loss of nearly 13%.

In this way,The computing power performance of RTX 6000D has been lost by about 23%, for example, it is about 97.04TFlops with FP32 precision, which is not even as good as the RTX PRO 6000 Max-Q version.

Even so, its strength cannot be underestimated and is still higher than RTX PRO 5000 48GB.

For example, when testing the DeepSeek R1 70B large model in LMStudio, the context length is 8000, the thinking time of RTX 6000D is only 13 seconds, and the output speed is24.79 Tokens per second, leading the RTX PRO 5000 by more than 10%.

If four cards are used in parallel, the video memory capacity will reach 336GB, and eight cards will be 672GB, which can run a quantitative 671B model.

As can be seen from the disassembly, its PCB layout is exactly the same as that of RTX PRO 6000.The only difference is that the 32 Samsung 3GB GDDR7 memory chips have been changed to 28, 14 on the front and back.

Note that although there are four DP interfaces on the left side, they cannot output video. Under Windows, it will be displayed asPurely computational TCC drive mode.

There is also a four-pin 3D stereo synchronization interface and a frame lock/sync interface on the top, and a 16-pin power supply interface at the rear.
