The latest crackdown on tech exports to China coincides with U.S. efforts to thaw difficult relations between the world's two largest economies. One, named the H800, has as much computing power at some settings used in AI work as the company's more powerful but blocked H100 chip. The U.S. now plans to introduce new guidelines for AI chips that will restrict certain advanced datacenter AI chips that are not currently captured, the U.S. official said. In order to keep AI chips the U.S. views as too powerful from China, the official said the U.S. planned to remove one of the parameters — the "bandwidth parameter" — it has used to restrict exports of certain AI data center chips. This would likely mean the speed at which AI chips talk to each other would be reduced.
