China’s AI Chip Race: Can Domestic Alternatives Overtake Nvidia Amid US Restrictions?
Table of Contents
As the U.S. government tightens restrictions on China’s access to advanced semiconductors crucial for artificial intelligence (AI) development, Beijing is doubling down on its efforts to foster a self-reliant domestic AI chip industry. This ambition faces meaningful hurdles, including limitations on acquiring essential chip design and manufacturing technologies.Despite investing tens of billions of dollars, China’s AI chip capabilities still lag behind global leaders like Nvidia, but progress is being made, especially by companies like Huawei. According to SemiAnalysis, Huawei’s Ascend 910C GPU is now only about a year behind Nvidia’s export-restricted H20 chip in performance, signaling a narrowing gap.
The Four Pillars of China’s AI Chip Ecosystem
Building a competitive AI chip ecosystem requires strength across four key areas: chip design, fabrication, equipment, and memory. Hear’s a breakdown of China’s current standing in each:
1. AI Chip Design: Closing the Gap
Nvidia, an american company, dominates the AI chip design landscape with its graphics processing units (gpus). While competitors like AMD exist, Nvidia’s GPUs are the industry benchmark. China’s Huawei, through its HiSilicon division, is emerging as a strong contender. Its Ascend 910B GPU is already in mass production,and the next-generation Ascend 910C is anticipated to further reduce the performance gap with Nvidia. semianalysis estimates the 910C is only a year behind Nvidia’s H20.
Did You know? Nvidia doesn’t manufacture its own chips; it outsources production to foundries like TSMC.
2. AI Chip Fabrication: SMIC’s Progress and Challenges
Taiwan Semiconductor Manufacturing Company (TSMC) is the world’s leading chip foundry, producing the majority of advanced semiconductors. However, TSMC adheres to U.S. export controls, preventing it from taking orders from blacklisted companies like Huawei. This forces Chinese designers to rely on domestic foundries, primarily Semiconductor Manufacturing International Corporation (SMIC).SMIC can produce 7-nanometer chips, but lags behind TSMC’s more advanced 3-nanometer technology. Smaller nanometer sizes generally equate to greater processing power and efficiency. Despite this, SMIC is suspected of producing a 5-nanometer chip for Huawei’s Mate 60 Pro in 2023, demonstrating progress. TechInsights provides in-depth analysis of SMIC’s technological advancements.
3. Advanced Chip Equipment: the Lithography Bottleneck
SMIC’s ability to meet Huawei’s GPU demands is constrained by export controls, particularly from the Netherlands.ASML, a Dutch company, is the world’s leading supplier of advanced chipmaking equipment, specifically lithography machines. These machines are essential for transferring intricate patterns onto silicon wafers. The Netherlands, complying with U.S. regulations, blocks the sale of ASML’s most advanced extreme ultraviolet (EUV) lithography machines to China. Jeff Koch, an analyst at SemiAnalysis, notes that EUV lithography is the most significant barrier to China’s advanced chip production. ASML’s website offers details on their lithography technology.
4. AI Memory Components: Catching Up in HBM
high Bandwidth Memory (HBM) is a critical component for AI applications, working alongside GPUs to store data. South Korea’s SK Hynix, Samsung, and U.S.-based Micron are the leading HBM manufacturers.South Korea also adheres to U.S. chip restrictions,limiting HBM sales to China. In response, Chinese memory chip maker ChangXin Memory Technologies (CXMT) is developing HBM in partnership with Tongfu Microelectronics. However, analysts estimate that CXMT is still several years behind the global leaders in HBM technology. SK Hynix is a major player in the HBM market.
china’s AI Chip ambitions: A Summary
| Area | Global Leader | China’s Status | Key Players |
|---|---|---|---|
| Chip Design | Nvidia (US) | Closing the gap | Huawei (HiSilicon), Enflame Technology, Biren Technology |
| Chip Fabrication | TSMC (Taiwan) | Lagging behind | SMIC |
| Chip Equipment | ASML (Netherlands) | Major bottleneck | SiCarrier Technologies |
| Memory (HBM) | SK Hynix (South Korea) | Early stages of development | CXMT, Wuhan Xinxin Semiconductor Manufacturing |

Evergreen Insights: The Broader Context
China’s push for domestic AI chip production is part of a broader strategy to achieve technological self-sufficiency and reduce reliance on foreign suppliers. This strategy is driven by concerns over national security and the potential for disruptions to supply chains. The U.S. export controls are intended to slow China’s technological advancement,but they also incentivize domestic innovation. The long-term impact of these policies on the global semiconductor industry remains to be seen.
