US blocks sale of some Nvidia and AMD AI chips to China

The US government has banned AMD and Nvidia from exporting chips used to support artificial intelligence work to China. The ban affects Nvidia's A100 chips, often deployed in data centers to speed up the training of machine learning models, and its forthcoming H100 chip, while AMD has also received new license requirements that will stop its MI250 advanced AI chip from being exported to China. In a filing with the SEC, Nvidia said: "The US government has imposed a new license requirement, effective immediately, for any future export to China (including Hong Kong) and Russia of the Company's A100 and forthcoming H100 integrated circuit." According to Nvidia, the US government has said that the new license requirement addresses the risk of these chips being used for military purposes in China and RussiaNividia said it does not sell products to customers in Russia. Nvidia also stated in its filing that the new license requirement may impact its ability to complete the development of H100 in a timely manner or support existing customers of A100, and may result in it having to move certain operations out of China.
