TL;DR
Loongson has unveiled the Loongson 3C3000, a 16-core server CPU built on its proprietary LoongArch architecture. This low-cost processor aims at small- and medium-sized business servers, supporting common enterprise workloads.
Loongson Technology has introduced the Loongson 3C3000, a new 16-core server processor based on its in-house LoongArch architecture. Unveiled on June 26, 2026, the chip is designed to serve low-cost, general-purpose server systems for small- and medium-sized businesses, supporting workloads such as file, database, web, and business process servers. This marks a significant step in Loongson’s efforts to develop domestic CPU technology for enterprise applications.
The Loongson 3C3000 features 16 physical cores and 16 threads, with clock speeds ranging from 1.5 GHz to 1.8 GHz. It is built on the LA364E processor core design and supports the LoongArch instruction set. The processor uses a 37.5mm by 37.5mm FCBGA1371 package and is pin-compatible with the Loongson 3B6000, facilitating reuse in existing platforms.
Each core includes 64KB of private L1 instruction and data caches, with a shared 16MB L2 cache. The integrated memory controller supports two DDR4-2400 ECC memory channels. Expansion options include two PCIe x16 interfaces (totaling 32 PCIe lanes) and an additional PCIe x16 interface configurable as a Loongson Coherent Link for dual-processor setups. Power consumption is listed at 40W at 1.5 GHz, with features to reduce energy use under lighter loads. The processor also incorporates a security module supporting Chinese cryptographic algorithms.
Loongson positions the 3C3000 as a cost-effective alternative for enterprise workloads, aiming at customers seeking general-purpose compute rather than high-end acceleration or AI. Unlike higher-core models like the 36C000, the 3C3000 is designed to be more affordable, supporting China’s local software and hardware ecosystem. Pricing has not been disclosed publicly.
Implications of Loongson’s 16-Core Server CPU Launch
The launch of the Loongson 3C3000 signifies a major milestone in China’s efforts to develop domestic server processors. By offering a cost-efficient and power-efficient CPU based on its LoongArch architecture, Loongson aims to reduce reliance on foreign chipmakers and bolster China’s local tech ecosystem. This development could impact global supply chains and foster local innovation in enterprise computing within China, especially as the processor supports Chinese cryptographic standards.
For the industry, this processor represents a strategic move toward self-sufficiency in server hardware. It also signals Loongson’s intention to compete in cost-sensitive segments, potentially influencing the market for entry-level enterprise servers. However, the processor’s performance and adoption in real-world applications remain to be seen, which could determine its long-term impact.

Background of Loongson’s Domestic CPU Development
Loongson Technology has been working since the early 2000s to develop homegrown CPU architectures to reduce dependence on foreign chipmakers. Its previous offerings include the Loongson 3 series, which aimed at high-performance computing and server markets. The company’s recent focus has been on building a complete ecosystem supporting its proprietary LoongArch instruction set, which is designed to be compatible with existing software while promoting China’s technological independence.
In 2025, Loongson launched the higher-core-count 36C000 processor, positioning it against Intel’s Xeon processors. The 3C3000 is part of the company’s strategy to offer more affordable solutions for SMB and enterprise workloads. The new processor’s announcement aligns with China’s broader push for domestic innovation in critical infrastructure hardware, amid ongoing geopolitical tensions affecting global chip supply chains.
