US orders immediate halt to some AI chip exports to China, says Nvidia

The chip designer Nvidia has said the US has told it to immediately halt the export of some of its high-end artificial intelligence chips to China as regulators advanced the deadline.

The restrictions were supposed to come into effect 30 days after 17 October, when the Biden administration announced measures to stop countries, including China, Iran and Russia, from receiving advanced AI chips designed by Nvidia and others.

Nvidia did not say why the US government had accelerated the timing but said it did not expect a near-term impact on its earnings from the move.

Fellow semiconductor company Advanced Micro Devices is also affected by the curbs, but did not immediately respond to Reuters’ requests for comment. The US Department of Commerce declined to comment.

Intel, which began selling its Gaudi 2 chips in China in July, said it was “reviewing the regulations and assessing the potential impact”.

The US export bar affects Nvidia’s modified advanced AI chips A800 and H800 – both of which were created for the Chinese market to comply with previous restrictions.
