The United States has confirmed that the latest AI chip controls will take effect ahead of schedule, which explains why Nvidia has suddenly cut off supply. Nvidia said the impact applies to shipments of products with a "total processing performance (TPP)" of 4800 or higher and designed or sold for data centers, namely the A100, A800, H100, H800 and L40S.
However, Nvidia did not disclose in the announcement whether the control of the consumer-grade graphics card RTX4090, which is on the edge of the restriction order, will take effect immediately.
According to U.S. officials, export controls on AI chips will be implemented in advance, restricting countries such as China, Saudi Arabia, the United Arab Emirates, and Vietnam from obtaining high-computing chips.
Nvidia previously explained the export controls, saying that it would affect A100, A800, H100, H800, L40, L40S and RTX4090 products, as well as Nvidia DGX and HGX artificial intelligence servers equipped with accelerators such as A100.
AMD was also affected by U.S. export control measures. Intel released Gaudi2 chips in China in July, but the October 17 ban included this product.
