The US has put export restrictions on the sale of  high-end GPUs and AI accelerators  to China.

It is estimated that it could reduce  Nvidia’s Q3 sales by $400 million, hitting its A100 and H100 ICs.

AMD is also affected with its  premium GPUs and MI250 AI accelerator IC on the restricted list

Both companies’ shares fell on the news.

 “The US side should immediately stop its wrongdoing, treat companies from all over the world including Chinese companies fairly, and do more things that are conducive to the stability of the world economy,” said the China government
