One of China’s largest server makers, H3C, has flagged potential shortages of Nvidia’s H20 chip, the most advanced AI processor legally available domestically under U.S. export controls, in a client notice seen by Reuters. The potential supply crunch could create obstacles for China’s artificial intelligence ambitions at a time when its tech firms are aggressively expanding their investments in AI. “H20’s international supply chain faces significant uncertainties,” the company said in Tuesday’s notice, adding that current inventory was nearly depleted.
