China is strategically advancing in the field of artificial intelligence (AI) chips, embracing a unique approach that diverges from the hot pursuit of massive computing power, models, and data. Instead, the focus is on empowering specific sectors to harness AI effectively, charting a course of differentiated innovation.
Former Minister of Industry and Information Technology Miao Wei has pointed out that China’s computing power gap with the United States is widening due to US restrictions on advanced AI chips. Despite this, Chinese institutions and companies are making headway. For instance, Tsinghua University has developed a cutting-edge “photonic chip” that sets new benchmarks for energy efficiency in AI applications.
Called “Taichi,” this innovative chip was inspired by the philosophy of dualism in I Ching and offers an energy efficiency of 160 TOPS/W. This impressive performance has been published in the reputed journal “Science,” and it marks a significant milestone in AI chip development.
Leveraging a joint propagation model of interference and diffraction, the team at Tsinghua University has engineered a scalable and versatile architecture for photonic computation. This architecture overcomes the limitations associated with traditional electronic chips, such as speed and power consumption, by using the properties of light for processing information.
Comparing the power efficiency of “Taichi” with existing AI chips—like the 920 with 5.714TOPS/W, NVIDIA’s H100 at 2.872TOPS/W, and the recent B200’s 4.5TOPS/W—highlights its technological advancements. It dramatically surpasses these contenders by several orders of magnitude in terms of energy efficiency.
While currently China relies on a domestic manufacturing breakthrough with the introduction of the 9000S series, the moment is not far when the entire semiconductor supply chain might see a complete upgrade. This would nullify the reliance on American AI chips, undermine their market in China, and ultimately secure China’s position in the global AI chip market.
With continuous iteration and technical upgrades, the potential of Taichi’s photonic chips is poised to revolutionize China’s industrial AI applications, indicating a significant leap towards technological sovereignty.
China’s drive for technological sovereignty in the AI chip sector responds to escalating geopolitical tensions and trade restrictions, especially from the United States. The US, in an attempt to maintain its technological edge, has placed a number of restrictions on China’s access to advanced semiconductor technology. These measures have included the export of critical semiconductor manufacturing equipment and the blacklisting of certain Chinese tech firms like Huawei from using American technology in their semiconductor design and production.
This pushback has prompted China to accelerate its domestic semiconductor and AI chip industry, striving for self-reliance to mitigate the risks of supply chain disruptions. In doing so, China is also building up its intellectual property portfolio and fostering home-grown innovation to reduce dependencies on foreign technologies.
Key challenges in this domain include China’s relative lack of experience in the semiconductor industry, the complexity of the technology, and the enormous capital required for R&D and production. Moreover, the international semiconductor supply chain is highly intricate, with interdependencies among global players; creating a fully self-sufficient supply chain is a monumental task. China’s progress is also potentially hindered by the ongoing talent war in the high-tech sector, where attracting and retaining skilled professionals is critical.
The controversies associated with China’s advancements often focus on the dual-use nature of semiconductor technology and AI chips. These technologies have both civilian and military applications, raising concerns among other nations regarding the potential for their use in military or surveillance capacities by the Chinese government.
On the other hand, the advantages are significant. High energy efficiency in chips like “Taichi” could lead to more environmentally friendly technology and lower operational costs for AI systems. Photonic chips offer the promise of overcoming the limits of electronic chips, paving the way for faster, more efficient computation.
However, there are disadvantages to consider. The pursuit of technological sovereignty and the decoupling from global tech ecosystems can lead to isolation and might slow down the pace of innovation due to less collaboration. Moreover, domestic production of leading-edge chips requires time to mature; in the interim, China may face challenges in fulfilling its need for high-end chips.
