Sept 30 (Reuters) - The Biden administration could shed
more light on a possible new rule for exporting high-performance
artificial intelligence chips to China "relatively soon," a
White House official said Friday.
Tarun Chhabra, an official with the National Security
Council who focuses on technology issues, said letters sent from
the U.S. Department of Commerce to Nvidia Corp and
Advanced Micro Devices Inc last month asking them to
stop shipments of chips that can be used for applications like
natural language processing and nuclear weapons research were
likely precursors to further regulation.
Speaking at an speaking at an event hosted by the Brookings
Institution, he did not say what form that regulation might
"They tend to be followed by a public rule or regulation,
laying out a rationale and the full approach," Chabbra said of
the letters. "I think we will be in a position to say more about
that relatively soon."
Reuters reported earlier this month that the U.S. Commerce
is preparing curbs on exporting AI chips that could be released
as soon as October.
The news on Sept. 1 that the chip companies had received
letters caused Nvidia's stock to fall after the company
disclosed the letters could affect as much as $400 million in
revenue in its current fiscal quarter.
American officials did not spell out how the new
restrictions might be written.
Nvidia CEO Jensen Huang said earlier this month that the
letters spelled out curbs on chips with a combination of a
chip's performance and its ability to connect to other chips to
move large amounts of data around a data center quickly,
criteria that affected only a small number of Nvidia's products.
In his remarks on Friday, Chabbra confirmed that the
restrictions affect only the most advanced chips and are
"structured as a combination of computing power but also
