Flags of China and US are displayed on a printed circuit board with semiconductor chips, in this illustration picture taken on Feb 17.US microchip export controls imposed last year to freeze China's development of supercomputers used to develop nuclear weapons and artificial-intelligence systems like ChatGPT are having only minimal effects on China's tech sector.
"The AI companies that we talk to seem to see the handicap as relatively small and manageable," said Charlie Chai, a Shanghai-based analyst with 86Research. The export restrictions have two parts. The first puts a ceiling on a chip's ability to calculate extremely precise numbers, a measure designed to limit supercomputers that can be used in military research. Chip industry sources said that was an effective action.
China is an important market for US technology companies, and selling products there helps create jobs for both Nvidia and its US-based partners, the company added. Nvidia has not disclosed the China-only H800 chip's performance details, but a specification sheet seen by Reuters shows a chip-to-chip speed of 400 gigabytes per second, less than half the peak speed of 900 gigabytes per second for Nvidia's flagship H100 chip available outside China.
