China Unveils First Fully Localized Server Powered by Dual Loongson 3C6000 CPUs and Proprietary Interconnect Technology
China has reached a pivotal milestone in its domestic computing ambitions with the debut of its first "100% localized" server, powered by dual Loongson 3C6000 CPUs, marking a major leap in its efforts to build a self-reliant IT infrastructure in response to ongoing U.S. export restrictions. The development was reported by MyDrivers, which highlighted the technological significance of the breakthrough for the Chinese semiconductor and enterprise server landscape.
This in-house server solution, engineered by Chinese CPU manufacturer Loongson, utilizes two 3C6000 processors, delivering up to 64 physical cores and 128 threads, interconnected through the company’s proprietary Loongson Coherent Link (LCL) technology. This interconnect, internally referred to as “Dragon Chain,” not only enables high-speed communication between CPUs but also paves the way for scaling up to 8-way configurations, potentially bringing the server capacity to 128 cores and 256 threads within a single rack—an ambitious and competitive architecture.
The Loongson 3C6000 is based on a 16-core, 32-thread configuration and represents a considerable leap over the company’s earlier 3C5000 series, with improvements across multi-core performance and scalability. The company claims that its 3C6000 CPUs are comparable to Intel's Xeon 4314, a processor from the Ice Lake generation with a similar core/thread design. While Loongson acknowledges that its performance is not yet equivalent to cutting-edge Western CPUs, the firm emphasizes long-term self-sufficiency and market readiness over short-term competitive parity.
Notably, the company's server is not only fully domestic in terms of CPU architecture but also in system design and interconnect, positioning it as a complete indigenous solution for China's growing cloud, AI, and enterprise computing sectors—especially in government and public sector deployments that are under pressure to localize technology stacks.
Loongson’s broader roadmap looks increasingly aggressive. The company recently announced its 3B6600 series CPUs, which are expected to compete with mid- to high-end Intel 12th and 13th Gen processors, and will notably feature integrated graphics (iGPU), aiming to further broaden adoption across mainstream markets.
As part of China’s wider industrial and technological policy, which seeks to de-risk supply chains and reduce reliance on Western semiconductor technologies, this advancement marks a tangible win for Beijing’s “de-Americanization” initiative in strategic sectors such as cloud infrastructure and defense computing.
What are your thoughts on China’s rapid advancement in self-developed server and CPU technology? Do you see Loongson gaining significant global traction, or will its impact remain primarily domestic? Let us know in the comments below.
