The Dragon Awakens: Can China’s LoongArch Compete Against AMD and Intel Titans?
Is a processor born out of technological sovereignty ambition capable of challenging the giants of Silicon Valley? For years, China’s Loongson Technology has diligently worked on its domestic CPU alternatives, evolving from licensed MIPS64 ISA cores to its own LoongArch architecture – inspired by modern ISAs like RISC-V. With the recent launch of the 12-core/24-thread Loongson 3B6000 desktop processor and its arrival in independent hands for Linux testing, we finally have concrete benchmarks pitting Chinese silicon against AMD’s blazing-fast Zen 5 (Ryzen) and Intel’s powerful Arrow Lake (Core Ultra) processors, alongside the popular Raspberry Pi 5 as an ARM reference. This isn’t just about raw speed; it represents a critical shift in processor diversity and geopolitical tech independence.
Scaling the Performance Mountain: LoongSon Enters the Arena
Benchmarking Chinese Innovation Under Linux. The opportunity to evaluate LoongArch performance firsthand arose when the Loongson Hobbyists Community provided Phoronix with a Loongson 3B6000-equipped micro-ATX motherboard (3B6000x1-7A2000x1-EVB). Packing dual-channel DDR4 ECC memory support, PCIe slots (two x16, one x4), M.2 NVMe storage, multiple SATA ports, and integrated HDMI/VGA graphics, this platform offered a solid desktop foundation. Powered by Linux, this independent testing aimed to move beyond theoretical specs and measure real-world application speed against the latest x86 heavyweights and accessible ARM offerings.
Dissecting the Dragon’s Hardware.
The Loongson 3B6000, launched commercially in 2025, marks a significant step for domestically-developed processors. Key specs include:
- Core Configuration: 12 Cores / 24 Threads (SMT2 enabled)
- Architecture: LoongArch, representing an evolutionary step beyond Loongson’s foundational work with MIPS64.
- Scalability: While the review sample sported 12 cores, Loongson offers variants scaling up to an impressive 64 cores for higher-end server applications.
- Motherboard Features: Reflecting modern desktop needs, the EVB board provides ample connectivity, crucial for comprehensive performance testing across a range of tasks.
Putting LoongArch Through Its Paces: Linux Benchmark Battleground
The Phoronix test suite unleashed hundreds of benchmarks, covering compute-intensive tasks ranging from scientific computing and rendering to file compression, cryptographic operations, and everyday application performance coding. Comparing the Loongson 3B6000 directly against:
- AMD Ryzen (Zen 5): Representing the peak of mainstream consumer x86 performance.
- Intel Core Ultra (Arrow Lake): Intel’s answer to Zen 5, with significant performance per watt improvements.
- Raspberry Pi 5: Extremely popular ARM-based SBC, providing context for lightweight workloads.
