The U.S. has expanded its restrictions on exports of Nvidia artificial intelligence chips to cover some countries in the Middle East. Previously, the sale of certain Nvidia chips had been banned in both China and Russia.

According to The Guardian, Nvidia said in a regulatory filing that the restrictions affected the company’s A100 and H100 chips, which are used to improve machine-learning tasks on artificial intelligence applications like ChatGPT.

Officials told the organization that the new export rule aims to address the risk that the products could be used in a “military end use” or by a “military end user” in China.

Nvidia’s rival, AMD, had also received a letter informing the company that it would be facing similar restrictions, according to a person familiar with the matter.

Nvidia said that the limitations would not have an “immediate material impact” on the company’s finances, and did not reveal which Middle Eastern countries would be affected by these restrictions.

“During the second quarter of fiscal year 2024, the USG (U.S. government) informed us of an additional licensing requirement for a subset of A100 and H100 products destined to certain customers and other regions, including some countries in the Middle East,” Nvidia said in a statement.

Nvidia said it made $13.5 billion in quarterly revenues in an announcement that came earlier in August, beating analyst expectations by $2 billion.
