Nvidia has told its China customers that its supply of H20 chips is limited and does not plan to restart production, The Information reported on Saturday. According to U.S. export restrictions, the H20 chip is the most powerful artificial intelligence chip allowed to be sold to China. The report quoted two people familiar with the matter as saying that the U.S. government's ban on sales of H20 chips in April forced Nvidia to cancel customer orders and cancel its scheduled manufacturing capacity at TSMC, which produced the chip.
