Loongson 3C3000 Server Chip Launches With 16 Cores and 3C5000-Level Performance

Loongson has introduced the 3C3000 server processor, a move that offers small and medium enterprises a lower-cost option for building server infrastructure. The chip targets the domestic Chinese manufacturing ecosystem, providing an alternative for organizations seeking to reduce hardware expenses while maintaining server reliability. This release expands the available choices for server builds that prioritize cost efficiency over peak performance metrics.

16-core LoongArch processor targets cost-effective server infrastructure

The processor features a 16-core design with 16 threads, built on the Loongson LA364E core architecture. It utilizes the company's proprietary LoongArch 64-bit instruction set, which distinguishes it from standard x86 or ARM-based server solutions. The chip operates at clock speeds between 1.5GHz and 1.8GHz, using a mature domestic manufacturing process to keep production costs manageable.

Specifications

• Cores/Threads: 16 physical cores / 16 threads
• Architecture: LoongArch 64-bit
• Clock Speed: 1.5~1.8GHz
• Process Node: Mature domestic process
• Package: FCBGA1371 (37.5mm×37.5mm)

Technical specifications include 64KB of L1 instruction and data cache per core, alongside a shared 16MB L2 cache for all cores. Memory support is limited to dual-channel DDR4-2400 with ECC, ensuring data integrity for server workloads. The processor provides 32 PCIe lanes through two x16 interfaces, allowing for multiple expansion cards, and maintains a typical power consumption of 40W at 1.5GHz.

Loongson claims the general computing performance of the 3C3000 matches that of the higher-end 3C5000 model. The company positions the chip as a cost-effective solution for small and medium enterprise servers, database applications, and web hosting services. The design includes integrated security modules that support national cryptographic standards for enhanced data protection.

The announcement marks a strategic expansion of Loongson's server lineup with a focus on accessible pricing and domestic supply chain stability. The 3C3000 provides a viable hardware foundation for organizations that require reliable server computing without the premium cost of flagship processors.
