Loongson Unveils 16-Core Server Processor 3C3000 Based on LoongArch

Chinese semiconductor company Loongson has unveiled its new server processor, the 3C3000, developed on the proprietary LoongArch architecture. The 16-core, 16-thread chip is designed for cost-effective server solutions targeting small and medium businesses. The manufacturer claims the new model delivers comparable overall computing performance to its predecessor, the 3C5000, while featuring lower power consumption.

The processor is housed in an FCBGA1371 package and maintains pin compatibility with the 3B6000 model, simplifying integration into existing platforms. Clock speeds range from 1.5 GHz to 1.8 GHz, with each core supporting 128-bit vector instructions and three-way out-of-order execution. The cache configuration includes 64 KB of L1 instruction and data cache per core, along with a shared 16 MB L2 cache.

The 3C3000 supports dual-channel DDR4-2400 with ECC, ensuring data integrity for critical business tasks. For peripheral connectivity, it offers 32 PCIe lanes that can be configured across multiple interfaces. The chip has a typical power consumption of 40W, and its integrated security module supports China's national cryptographic algorithms.

Loongson positions the 3C3000 as an accessible alternative for entry-level servers, emphasizing compatibility with local software and hardware ecosystems. The processor's pricing remains undisclosed, as distribution is handled through partners and corporate contracts.
