China Advances AI Chip Self-Sufficiency, Yet Struggles with High-End Development

Summary: Huawei's subsidiary HiSilicon has made progress in developing AI chips, but potential risks in production and U.S. sanctions have led Chinese companies like Baidu and Alibaba to invest in autonomous AI chip development, posing long-term challenges for China's adoption of advanced processes and chip development.

  • Huawei's subsidiary HiSilicon has made notable progress in the independent research and development of AI chips.
  • The Ascend 910B chips are not only used in Huawei's public cloud infrastructure but also sold to other Chinese companies, indicating their high demand and potential for success.
  • Chinese cloud service providers like Baidu and Alibaba are actively investing in autonomous AI chip development, showing a strong commitment to developing their own technology and reducing reliance on foreign companies.


Huawei’s subsidiary HiSilicon has made notable progress in the independent research and development of AI chips with the launch of the next-gen Ascend 910B. These chips are not only used in Huawei’s public cloud infrastructure but also sold to other Chinese companies. Baidu, for instance, has ordered over a thousand Ascend 910B chips to build around 200 AI servers. Additionally, iFlytek, in collaboration with Huawei, has released the “Gemini Star Program,” a hardware and software integrated device for exclusive enterprise LLMs, equipped with the Ascend 910B AI acceleration chip.

According to TrendForce’s research, it is speculated that the next-generation Ascend 910B chip is manufactured using SMIC’s N+2 process. However, there are two potential risks in production. Firstly, as Huawei has been focusing on expanding its smartphone business, the N+2 process capacity at SMIC is primarily allocated to Huawei’s smartphone products, which could limit future capacity for AI chips. Secondly, SMIC is on the Entity List, which may restrict access to advanced process equipment.

Market analysis suggests that the performance of the Ascend 910B slightly lags behind the A800 series, and its software ecosystem differs significantly from nVidia’s CUDA, affecting usage efficiency. However, considering the potential expansion of U.S. restrictions, Chinese manufacturers might be compelled to shift towards the Ascend 910B. There is still considerable potential for China to improve and establish a complete AI ecosystem.

Chinese cloud service providers (CSPs) like Baidu and Alibaba are actively investing in autonomous AI chip development due to U.S. sanctions. Baidu has developed its first self-researched ASIC AI chip called Kunlunxin, with plans for mass production of its second generation in 2021 and the third generation expected to launch in 2024. After 2023, Baidu aims to use Huawei’s Ascend 910B acceleration chips and expand the use of Kunlunxin chips for its AI infrastructure.

Alibaba, on the other hand, acquired CPU IP supplier Zhongtian Micro Systems in 2018 and established T-Head Semiconductor the same year to develop its own ASIC AI chips, including the Hanguang 800. Initially, T-Head’s ASIC chips were co-designed with external companies like GUC, but after 2023, Alibaba is expected to rely more on its internal resources to enhance the independent design capabilities of its next-gen ASIC chips, primarily for Alibaba Cloud’s AI infrastructure.

The U.S. sanctions have limited China’s high-end AI chip development. The inclusion of companies like Biren and Moore Threads in the Entity List and the introduction of regulations governing advanced manufacturing processes have complicated the supply of high-end AI chips from leading manufacturers like NVIDIA and AMD. Furthermore, restrictions on EDA semiconductor design software tools have affected the design of advanced processes. While these restrictions may not have an immediate significant impact, they pose long-term challenges for China in adopting more advanced processes and developing next-gen, higher-performance HPC or AI chips.
