Loongson Unveils Powerful New Server Processor Set To Revolutionize Small Business Computing

On June 26, 2026, Loongson Technology announced its new 16-core server processor, the Loongson 3C3000. This groundbreaking chip is designed for small- and medium-sized business workloads, including file, database, web, and business process servers.

The Loongson 3C3000 features a general-purpose computing performance comparable to the company’s higher-end 3C6000 server lineup, suggesting it is well-suited for a wide range of workloads. Built on the company’s proprietary LoongArch architecture, this chip boasts impressive performance capabilities that rival its earlier 3C5000 server processor.

The new chip supports a 64-bit architecture and the LoongArch instruction set. It utilizes the LA364E processor core design, providing a robust foundation for its performance capabilities. The Loongson 3C3000 comes in an FCBGA1371 package measuring 37.5mm by 37.5mm and is pin-compatible with the Loongson 3B6000 processor. This compatibility ensures that system builders can easily reuse existing platform designs, making it easier to integrate the new processor into their systems.

With 16 physical cores and 16 threads, clock speeds ranging from 1.5 GHz to 1.8 GHz, and support for 128-bit vector instructions and three-issue out-of-order execution, this chip is well-suited for complex workloads. The Loongson 3C3000 also incorporates two fixed-point units, one vector unit, and two memory access units in each core.

The chip features a modest cache hierarchy: each core includes 64KB of private L1 instruction cache and 64KB of private L1 data cache, while all 16 cores share a 16MB L2 cache. The integrated memory controller supports two 72-bit DDR4-2400 memory channels with ECC support, providing server-class error correction for business and infrastructure workloads.

For expansion, the Loongson 3C3000 provides two PCIe x16 interfaces, totaling 32 PCIe lanes. These can be split into up to four x4 or x8 interfaces, depending on platform requirements. The chip also includes another PCIe x16 interface that can be configured as LCL for dual-processor interconnection. Other interfaces include SPI, UART, three I2C interfaces, AVS, and 16 GPIOs.

One of the standout features of the Loongson 3C3000 is its power efficiency. The chip has a typical power consumption of 40W when running at 1.5 GHz, with dynamic shutdown of the main module clock and dynamic frequency adjustment of the main clock domain to further reduce power waste and environmental impact.

The processor also incorporates a Loongson-developed security and trust module that supports Chinese national cryptographic algorithms for encryption and decryption. This feature is particularly appealing to customers in China, who may prioritize local software and hardware solutions.

Positioned as a low-cost, high-performance server CPU for general-purpose computing rather than high-end acceleration or AI performance, the Loongson 3C3000 is an attractive option for customers requiring reliable and efficient servers without breaking the bank. While pricing has not been publicly disclosed, its impressive features, power efficiency, and support for China’s local software and hardware ecosystem make it poised to make waves in the server processor market.

The Loongson 3C3000 represents a significant breakthrough in server processor technology, offering a unique blend of performance, power efficiency, and affordability. As the computing landscape continues to evolve, this chip’s features and capabilities are likely to appeal to a wide range of customers seeking reliable and efficient servers for their business needs.

The Loongson 3C3000 is also an important development in China’s indigenous technology sector, showcasing the country’s growing prowess in the global semiconductor industry. With its innovative architecture, robust performance capabilities, and emphasis on power efficiency, this chip is well-positioned to contribute to China’s efforts to become a major player in the world of server processors.

As the server processor market matures, it will be interesting to see how the Loongson 3C3000 fares against other competitors. With its impressive features, competitive pricing, and growing support for China’s local software and hardware ecosystem, this chip is poised to make a significant impact in the industry.
