| Why are Chinese telcos switching to domestic CPUs is not unclear. The motivations, complexities will make a new future of the tech business. |
Chinese telecommunication giants are undergoing a significant shift in their server infrastructure, increasingly opting for domestic CPUs. This move is driven by a two-pronged strategy: achieving self-sufficiency in core technologies and mitigating the risk of disruptions caused by US export restrictions. However, a closer look reveals a complex reality where domestic aspirations intertwine with foreign technological foundations.
Companies like China Telecom, China Mobile, and China Unicom are actively procuring servers equipped with CPUs from Huawei (Kunpeng), Hygon, and Loongson. This trend is evident in the rise of "G-series" servers, designated specifically for those utilizing domestically produced processors. Compared to just a few years ago, where Intel held a dominant position, Chinese-made CPUs are rapidly gaining traction. This shift is partly driven by concerns about the US government's tightening export controls on high-performance processors to China. The potential for further sanctions has spurred Chinese telcos to diversify their supply chains and reduce their dependence on foreign technology.
While the headlines celebrate a move towards domestic CPUs, a deeper examination reveals a crucial detail: most of these processors rely heavily on foreign-developed technology. Huawei's Kunpeng CPUs, for instance, utilize a customized Arm ISA (instruction set architecture), which has its roots in the US and UK. Similarly, Hygon processors incorporate AMD's x86 cores, albeit with modifications made in the US. Even LoongArch, touted as a fully domestic architecture, draws inspiration from the US-developed MIPS ISA.
This dependence on foreign technology highlights the challenges China faces in achieving complete self-sufficiency in CPU design. While domestic companies are making significant strides in chip manufacturing and engineering advancements, replicating the decades of research and development behind established architectures like x86 and Arm remains a significant hurdle.
Despite the reliance on foreign foundations, it's important to acknowledge the progress China has made in domestic CPU development. Manufacturers like SMIC's advancements in 7nm process technology have demonstrably contributed to performance improvements and cost-effectiveness for Chinese-made CPUs. This, coupled with ongoing research and development efforts, suggests a promising future for domestic CPU capabilities.
China's pursuit of technological independence is not a zero-sum game. The country's Vice Premier, He Lifeng, even emphasizes the importance of attracting foreign investment and allowing foreign technologies to enter the Chinese market. This highlights China's understanding that complete isolation is neither practical nor desirable. However, the US government's export restrictions, often justified by national security concerns, create a complex situation.
The future of China's CPU landscape will likely be shaped by a dynamic interplay between several factors. US export regulations, the pace of technological innovation in China, and the country's ability to attract foreign investment will all play crucial roles. While Chinese telcos are making headway in adopting domestic CPUs, true self-sufficiency remains a long-term goal. Continued advancements in domestic chip design and manufacturing, coupled with strategic partnerships and a globalized approach to technology, will be key to China's success in this endeavor.
