NVIDIA has started selling the RTX 4090 graphics card in China again, but has slowed it down by 11% to comply with US export restrictions, reports The Register.

The RTX 4090D, a special version for export to China, started appearing in Chinese stores on Thursday. The video card differs in that it has 14,592 CUDA cores versus 16,384 in the global version. As a result, the 4090D is 10.94% slower.

In a commentary to The Register, NVIDIA also said that the number of tensor cores of the card was reduced by a similar amount from 512 to 456 in the 4090D.

The RTX 4090 was the only graphics card to fall under US export restrictions to China. In addition, the company is also working with the US government to optimize future chips for export.
