en.Wedoany.com Reported - Loongson Technology released its new 16-core server processor, the Loongson 3C3000, on June 26, 2026. Based on Loongson's proprietary architecture, the chip is primarily designed for low-cost general-purpose server systems, capable of handling workloads such as file, database, web, and business process servers commonly found in small and medium-sized enterprises. Loongson stated that the general-purpose computing performance of the 3C3000 is on par with the company's previously launched 3C5000 server processor.
The Loongson 3C3000 adopts a 64-bit architecture, supports the LoongArch instruction set, and integrates the company's self-developed LA364E processor core. It is packaged in FCBGA1371 form factor, measuring 37.5 mm × 37.5 mm. The processor is pin-compatible with the Loongson 3B6000, a design feature that allows system manufacturers to directly reuse existing platforms, reducing development costs.
The processor features 16 physical cores and 16 threads, with a clock frequency range of 1.5 GHz to 1.8 GHz. Each core supports 128-bit vector instructions and three-issue out-of-order execution, integrating two fixed-point units, one vector unit, and two memory access units. In terms of cache configuration, each core has 64 KB of private L1 instruction cache and 64 KB of private L1 data cache, while all 16 cores share 16 MB of L2 cache. The memory controller supports two 72-bit DDR4-2400 memory channels with ECC functionality, providing server-grade error correction for critical business and infrastructure workloads.
For expansion, the Loongson 3C3000 offers two PCIe x16 interfaces (totaling 32 PCIe lanes), which can be split into up to four x4 or x8 interfaces based on platform requirements. The chip also includes an additional PCIe x16 interface, configurable as the Loongson Coherency Link (LCL) for dual-processor interconnection. Other interfaces include SPI, UART, three I2C interfaces, AVS, and 16 GPIOs.
According to Loongson's published data, the processor has a typical power consumption of 40W when running at 1.5 GHz. The chip supports dynamic clock gating of main modules and dynamic frequency adjustment of the main clock domain, helping to reduce power consumption under light load conditions. Additionally, the processor integrates Loongson's self-developed security and trusted modules, supporting China's national cryptographic algorithms for encryption and decryption operations.
Unlike Loongson's previous 3C6000 series, which was positioned against Intel Xeon processors, the 3C3000 is positioned as a low-cost, energy-efficient server CPU. It targets customers requiring general-purpose computing capabilities rather than high-end acceleration or AI performance, sitting below the high-core-count 3C6000 server series launched a year ago. Loongson emphasized that the processor's support for China's local software and hardware ecosystem is also a key selling point. The company has not publicly disclosed pricing, which is common practice for server processors—such products are typically sold through system manufacturers and negotiated through enterprise deals, rather than being marketed as boxed retail chips.
