Loongson Technology

What Loongson Technology does

Loongson Technology (龙芯中科技术股份有限公司) is a Beijing-headquartered, publicly listed Chinese fabless semiconductor company (Shanghai Stock Exchange STAR Market, ticker 688047, founded 2008) that designs general-purpose CPUs, embedded CPUs, and companion chips on its proprietary LoongArch (龙架构) instruction set architecture. The proprietary ISA, introduced in 2020 with approximately 2,000 instructions and GNU ELF machine number 258, underpins an internally developed core family (LA664, LA464, LA364, LA264, LA132) and GPGPU family (LG100, LG200), together with national-standard cryptographic modules and a Loongson Coherent Link (LCL) interconnect that scales server processors to 256 cores. The product portfolio covers high-performance desktop and server parts (3A6000, 3C6000, 3D5000, 3C3000, 3B6000/M), industrial-grade and embedded variants (2K/2P/1D/1C series), bridge chips (7A series), and supporting software (Loongnix Linux, LoongOS RTOS, Loongson Cloud).

The company operates a sales-led go-to-market targeting government and state-owned enterprise offices, K-12 and higher education, industrial control and IoT, server and data center customers, plus telecom and energy; revenue is generated through chip sales, system solutions, and software/ecosystem licensing. Distribution combines direct sales to key accounts, a regional eco-partner network (approximately 100 partners in Henan Province alone), OEM embedding (notably with Deli Group for printers and PCs), and an adaptation/certification platform supported by upstream open-source integrations in Alpine Linux 3.21 and deepin V23. Named customers and pilots include Deli Group in office equipment, Decard Technology in healthcare, and the Hebi City Education Bureau, where approximately 10,000 Loongson 3A5000-based computers have been deployed across roughly 50 schools as the foundation of Henan's education innovation initiative.

Scale indicators5 records

Recent moves7 records

Expansion highlights5 records

Broad incumbents

• Intel Corporation: Global leader in x86 CPUs spanning desktop, server, and embedded. Loongson competes against Intel in domestic Chinese government and enterprise procurement, positioning its LoongArch CPUs as an Intel alternative for sovereignty-driven buyers.
• AMD (Advanced Micro Devices): Major x86 CPU and GPGPU vendor competing with Intel in server and desktop. Loongson's 3C and 3D server lines are positioned as domestic alternatives to AMD EPYC for Chinese data centers and cloud workloads.
• NVIDIA: Dominant GPGPU and AI accelerator vendor. Loongson's LG200 GPGPU is positioned as a domestic alternative for Chinese AI inference workloads where end customers require non-NVIDIA silicon.
• MediaTek: Taiwanese fabless semiconductor company producing ARM-based SoCs for mobile, embedded, and increasingly server/edge. Comparable to Loongson in offering multi-core application processors and embedded SoCs, though serving different geographies and customer bases.

Direct peers

• HiSilicon (Huawei): Huawei's chip design subsidiary producing Kunpeng ARM-based server CPUs and Kirin SoCs. Both HiSilicon and Loongson target Chinese domestic replacement of foreign CPUs in servers and embedded systems under tech sovereignty mandates.
• Phytium Technology: Chinese ARM-based server and desktop CPU designer. Competes with Loongson in domestic government, military, and SOE procurement for secure computing platforms, representing an alternative domestic architecture choice.
• Shanghai Zhaoxin Semiconductor: Joint venture between VIA Technologies and Shanghai government producing x86-licensed CPUs for Chinese PC and server markets. Competes with Loongson in the same domestic CPU substitution space with a different licensing approach.
• Sunway (National Research Center of Parallel Computer Engineering and Technology): Designs the Sunway domestic CPU architecture used in Chinese supercomputers. Competes with Loongson as another purely domestic (non-ARM, non-x86) CPU alternative for Chinese high-performance and government computing.

Emerging players

• Ampere Computing: US-based ARM server CPU startup. Comparable to Loongson in pursuing ARM-compatible/server CPU architectures for cloud and data center workloads, though serving primarily Western hyperscaler customers.
• Cambricon Technologies: Chinese AI accelerator chip designer. While Cambricon focuses on AI training/inference ASICs, it competes with Loongson's GPGPU efforts for domestic AI compute share in Chinese data centers.
