TL;DR
Loongson has announced the Loongson 3C3000, a 16-core server CPU built on its LoongArch architecture. The chip aims at small- and medium-sized business servers, matching performance of earlier models but with new features. The development marks a significant step in China’s domestic chip industry.
Loongson Technology has introduced the Loongson 3C3000, a 16-core server processor based on its LoongArch architecture, aimed at low-cost, general-purpose server systems. The announcement was made on June 26, 2026, via a public corporate release. The chip is designed for small- and medium-sized business workloads, including file, database, web, and business process servers, and is positioned to compete in the entry-level server market.
The Loongson 3C3000 features 16 physical cores and supports 16 threads, with clock speeds ranging from 1.5 GHz to 1.8 GHz. It is based on the LA364E processor core and supports LoongArch instruction set. The processor comes in an FCBGA1371 package measuring 37.5mm by 37.5mm, and is pin-compatible with the Loongson 3B6000 platform, facilitating reuse of existing designs.
Designed for efficiency, the chip supports two DDR4-2400 memory channels with ECC, providing server-class error correction. It includes two PCIe x16 interfaces (totaling 32 lanes), which can be split into multiple configurations, along with additional interfaces like SPI, UART, I2C, AVS, and GPIOs. Power consumption is listed at 40W at 1.5 GHz, with features to reduce power use under lighter workloads. It also incorporates a security module supporting Chinese cryptographic algorithms.
Loongson positions the 3C3000 as a low-cost, high-performance alternative for general-purpose server workloads, distinct from higher-end models like the 3C6000, which target more demanding applications. The company has not disclosed pricing details publicly.
Implications for China’s Domestic Tech Industry
The launch of the Loongson 3C3000 marks a notable milestone in China’s effort to develop independent, domestically-produced server processors. By providing a cost-effective chip built on its own architecture, Loongson aims to reduce reliance on foreign semiconductor technology, which is a strategic priority for China. This development could influence the local server market, encourage domestic hardware ecosystem growth, and bolster China’s technological sovereignty in enterprise computing.

Loongson’s Progress in Domestic Processor Development
Loongson has been working on its LoongArch architecture for several years, aiming to establish a fully domestic CPU ecosystem. Previous models, including the higher-core-count 3C6000, targeted more advanced workloads, but the 3C3000 is positioned as an accessible, low-cost option for SMBs and entry-level servers. The company’s efforts align with China’s broader strategy to develop independent chip supply chains amid global supply chain tensions.
This announcement follows earlier launches of Loongson processors, which have gradually increased in performance and complexity, signaling progress toward self-sufficiency in enterprise-grade CPUs.
“Loongson’s new 16-core processor demonstrates China’s growing capability to produce competitive server chips using domestically developed architecture.”
