Analysis of China's Domestic CPU Landscape: Architecture, Security, and Market Challenges

CPU autonomy and security are not simple binary decisions but complex analyses that must consider both the current ecosystem and the need for independent research and development.

Since the 1984 Los Angeles Olympics, China has sought to break its reliance on foreign technology, yet the domestic computer market remained dominated by imported hardware and software, creating a "thorn" of security concerns.

Trade tensions have highlighted the critical role of CPU development as a bottleneck; the two key factors for a CPU are its architecture (the physical design) and its instruction set (the functional specification), historically represented by families such as x86, ARM, PowerPC, Alpha, and SPARC.

Domestic CPU vendors—Loongson, Shenwei, Feiteng, Kunpeng, Zhaoxin, and HaiGuang—follow different licensing models, ranging from purchasing perpetual ARM v8 patents to buying MIPS designs, each facing challenges in ecosystem support and future architectural upgrades.

Industry experts argue that true security comes from writing every line of code in-house, regardless of the chosen architecture, while others caution that reliance on foreign core licenses (e.g., X86) limits long‑term independence.

Historical projects such as the "909" initiative illustrate the difficulty of rapidly closing the semiconductor gap, emphasizing that semiconductor development differs fundamentally from strategic defense programs and requires a balanced, market‑driven approach.

The prevailing strategy in China is a “two‑legged” approach: supporting indigenous instruction‑set architectures while also fostering market space for companies using mainstream standards, aiming to avoid a cycle of perpetual importation without domestic innovation.
