Huawei Battles AI Chip Yield Woes Amid U.S. Trade Restrictions and Rising Costs
  • Huawei is grappling with significant production challenges for its advanced AI chips, particularly the Ascend 910C, which currently has a commercially viable yield of only about 20%.

  • The U.S. export controls are a major hurdle, preventing China from acquiring critical technologies such as extreme ultraviolet (EUV) lithography equipment, essential for producing sophisticated processors.

  • Despite these efforts, Huawei's production issues are compounded by limitations in its software ecosystem, particularly within its Cann software, which affects overall efficiency.

  • Future U.S. export controls on the semiconductor industry are anticipated, especially if Donald Trump returns to the presidency in January 2025, which could reinforce tough trade policies towards China.

  • In response to these restrictions, Huawei is prioritizing strategic government and corporate orders, recognizing the long-term challenges posed by the lack of EUV technology.

  • The Chinese government is backing its semiconductor ambitions with a nearly $48 billion fund, which includes over $1 billion in grants to Huawei in 2023.

  • The Ascend 910C is designed to compete with Nvidia's AI chips and has already been distributed to tech firms for sampling and orders, although supply issues persist.

  • Chinese companies, including ByteDance, have expressed frustration over slow delivery rates of Huawei's chips, receiving significantly fewer units than ordered.

  • Reports indicate that SMIC, Huawei's primary chip manufacturer, charges a premium for chips produced on its advanced nodes, which are less sophisticated than those made by TSMC, contributing to higher costs.

  • Nvidia, which previously held a 90% share of the Chinese AI chip market, has seen its revenue from China impacted by ongoing restrictions since 2022.

  • As Huawei seeks to expand its customer base for AI processors domestically in China, it faces significant challenges due to the ongoing U.S. trade restrictions that affect its operations.

  • Overall, while Huawei's 910C chip is reported to outperform Nvidia's upcoming B20 chip, the company must navigate a complex landscape of supply chain and regulatory challenges.
