Facing U.S. sanctions, Huawei has largely focused its AI accelerator efforts within China. These restrictions, intended to limit China’s access to advanced technology, may have inadvertently bolstered Huawei’s domestic market share. Now, Nvidia is devising strategies to compete in China despite these limitations.
Nvidia is set to begin production this month on the B40 AI accelerator, a chip specifically tailored for the Chinese market.Engineered with Nvidia’s Blackwell architecture, the B40 is designed to comply with U.S. export regulations, allowing its sale in China. amidst the surging demand for AI capabilities, Chinese customers are reportedly prioritizing vendors with readily available stock.
Meanwhile, Huawei’s plans to manufacture its new Ascend 910C AI accelerator this month have been delayed.According to sources on X, mass production is now expected towards the end of the year due to unspecified technical challenges. The delay is further compounded by supply chain issues and the limited availability of competing chips from other domestic manufacturers.
Manufacturing Processes and Performance
“Sell only what you already have in stock; if you fail to deliver, you’re in trouble.”
When production of the Ascend 910C eventually commences, Semiconductor Manufacturing International Corporation (SMIC) will fabricate the chip using its second-generation 7nm process (N+2). In contrast, Taiwan Semiconductor Manufacturing Company (TSMC) produces Nvidia’s H20 GPU using a more advanced 4nm process. This difference in manufacturing processes could perhaps result in the Ascend 910C exhibiting lower performance and energy efficiency compared to Nvidia’s H20.
