Loongson Technology (loongson.cn) provides domestic CPUs and ecosystem-building services, and is a core player in China’s self-developed instruction set processor sector. Incubated by the Institute of Computing Technology, Chinese Academy of Sciences, it mainly serves the Xinchuang industry and domestic substitution needs. Users typically choose it to reduce dependence on x86 and ARM architectures, achieve chip-level autonomy and control in critical sectors such as government, defense, and finance, and gain access to supporting hardware and software ecosystem resources.
Loongson Technology traces its roots back to the “Loongson” project launched in 2001. The company was formally established in 2010 and listed on the STAR Market in 2022. Its core business is built around its self-developed LoongArch instruction set architecture, offering full-stack solutions from CPU chip design to foundational software such as operating systems, compilers, and JVMs. In terms of industry positioning, Loongson is the only CPU vendor in China that has consistently followed a self-developed instruction set route, differentiating itself from ARM-based Huawei Kunpeng and x86-based Zhaoxin. Its customers are mainly government and enterprise users, defense organizations, universities, and research institutions. Domestic operating systems such as NeoKylin and UnionTech UOS have already completed adaptation for Loongson. Service formats include chip sales, development boards, ecosystem adaptation certification, and technical training. However, as a chip design company, Loongson does not really offer “plans” for individual developers in the way cloud or SaaS providers do; complete machines and development environments are more commonly provided through partners.
Loongson is best suited to three types of users. First, system integrators and software developers in the Xinchuang sector that need to port and optimize applications for the Loongson platform. Second, universities and research institutions using it for teaching or research into self-developed instruction set architectures. Third, government and enterprise organizations with extremely high security requirements that need to eliminate backdoor risks at the hardware level. Individual developers or small teams with a strong interest in domestic self-developed CPUs can also buy Loongson development boards for low-level experimentation. However, it is not a good fit for ordinary consumers or users seeking maximum performance, because Loongson’s desktop ecosystem is still underdeveloped, and mainstream games and professional software such as Adobe products are difficult to run directly. In addition, if a project requires rapid iteration and depends heavily on ready-made libraries, the adaptation workload on Loongson will be significantly higher than on x86 or ARM platforms.
Loongson uses a B2B chip sales model rather than standardized cloud service or software subscription pricing, so “monthly/yearly fees” are not publicly listed and are not applicable to individual monthly payments. CPU chip pricing depends on the model and purchase volume. For example, the retail channel price of a 3A5000 desktop CPU is roughly RMB 500-800 per chip, while complete machines such as Lenovo Kaitian-series PCs are priced at around RMB 4,000-8,000, on par with or slightly higher than x86 machines of similar performance. In terms of value for money, Loongson is not as strong as similarly priced x86 options in raw compute power. However, when Xinchuang subsidies and compliance costs are considered, it can offer hidden advantages for government and enterprise customers. There are no hidden fees, but individuals buying development boards, which cost around RMB 2,000-5,000, should account for shipping and taxes. Overall, it sits in the mid-to-high price range because R&D costs are spread over relatively limited volume, and production has not yet reached full economies of scale.
Users in mainland China can access loongson.cn directly without a VPN, and the site generally loads smoothly. For payments, the official site supports corporate bank transfers, Alipay, WeChat Pay, and other methods, making it convenient for individuals to buy development boards. Enterprise customers can request VAT invoices, including both ordinary and special VAT invoices, to meet reimbursement requirements. Domestic alternatives include Huawei Kunpeng (ARM architecture), Phytium (ARM architecture), Zhaoxin (x86-compatible), and Hygon (x86-compatible). Loongson’s biggest differentiator is its “fully self-developed instruction set.” For development, users are advised to download Loongnix system images from the official website or use the QEMU emulator, which supports LoongArch, for cross-compilation. On the hardware side, users can buy Loongson 3A5000 mini PCs or development boards. Note that because the ecosystem is relatively narrow, some common Linux software, such as official Docker images, may need to be compiled manually, which creates a certain entry barrier.
Pros:
Cons:
Loongson’s positioning is “the most autonomous but the least compatible.” It suits scenarios that need security guarantees from the lowest level. Kunpeng and Phytium are better for scenarios that need a balance between ecosystem compatibility and security, while Zhaoxin is better for scenarios where maximum compatibility is required.
Loongson is best suited to low-level hardware replacement and autonomy requirements in Xinchuang projects, especially for core systems in Party and government agencies, defense, finance, and similar sectors. If your team has Linux development capabilities and is willing to invest time in adaptation, Loongson is a safer long-term choice. It is not suitable for high-performance computing, projects dependent on closed-source commercial software, or individual developers who need to launch quickly. Since Loongson does not offer a free trial and the chips must be purchased, it is recommended to first apply for a development board via the official website or evaluate adaptation difficulty using a QEMU simulation environment before deciding on bulk procurement. For ordinary users, it is not currently recommended as a primary development machine.
