Loongson 3B6000M: A Comprehensive Overview of Specifications and Performance

The Loongson 3B6000M is an 8-core System-on-Chip (SoC) developed by Loongson Technology, officially released in June 2025. Built on the fully self-developed LoongArch instruction set architecture, it is primarily targeted at mobile terminals—including laptops, cloud terminals, and industrial control devices—as well as edge AI applications. The chip represents a significant milestone in China's push for a fully domestically controlled computing ecosystem, from instruction set to IP cores to final silicon.

Core Architecture and Processing

At the heart of the 3B6000M are 8 high-performance 64-bit LA364E processor cores, based on Loongson's fourth-generation microprocessor architecture. Each core features a 3-wide superscalar out-of-order execution design with 2 integer units, 2 floating-point units, and 2 load/store units. The chip supports 128-bit vector instructions and the LoongArch instruction system natively.

Each core is equipped with 64KB of private L1 instruction cache and 64KB of private L1 data cache. All 8 cores share a 6MB last-level (L2) cache.

The chip's clock frequency is rated at 2.4–2.5GHz depending on the product variant. At 2.5GHz, the processor achieves a measured SPEC CPU 2006 Base single-core integer score of 30 points, with single-thread integer and floating-point peak performance both exceeding 10 points/GHz—a substantial improvement over previous-generation Loongson mobile chips.

GPU and AI Acceleration

The 3B6000M integrates Loongson's second-generation self-developed GPGPU core, the LG200. Compared to the previous LG100, graphics performance has improved by more than 60% (with some sources citing a doubling of performance). The GPU supports mainstream graphics APIs including OpenGL 3.3, OpenGL ES 3.1, and OpenCL 1.1.

For AI workloads, the LG200 delivers over 7 TOPS of INT8 AI acceleration throughput and 256 GFLOPS of single-precision floating-point peak performance, enabling on-device AI inference for smart office applications, lightweight data analytics, and intelligent image processing.

Video Processing and Display

An independent hardware video codec engine (VPU) is integrated, supporting a wide range of formats:

• Decoding: HEVC (H.265), H.264, VP8, VP7, AV1, MPEG-4, JPEG

• Encoding: HEVC, H.264, JPEG

• Maximum throughput: 4K at 60 FPS

The display subsystem supports dual-channel triple-display output via eDP, DisplayPort, and HDMI interfaces, with a maximum resolution of 4K@60Hz (some product configurations list 4K@30Hz depending on the display path).

Memory and I/O

• Memory controller: Single-channel 64-bit DDR4 or dual-channel 32-bit LPDDR4

• High-speed I/O: 8-lane PCIe 3.0, 4× USB 3.1, 4× USB 2.0, 1× SATA 3.0, 2× Gigabit Ethernet ports

• Other I/O: eMMC, SDIO, SPI, LPC, HDA, I2S, UART, I2C, GPIO, RapidIO, and CAN-FD

Security Features

The chip integrates a dedicated security processor that provides trusted computing support and cryptographic services. It includes hardware-accelerated SM2/SM3/SM4 (Chinese national cryptographic standard) algorithm modules, as well as a reconfigurable cryptographic module available for software programming. The 3B6000M has earned the highest Level II certification from the China Information Technology Security Evaluation Center (CNITSEC), making it suitable for deployment in government, finance, energy, and other critical infrastructure sectors.

Power Management

The chip supports dynamic clock gating for major modules, dynamic frequency scaling, and dynamic voltage and frequency scaling (DVFS). A 2.0GHz variant has a TDP of approximately 35W, with typical usage power as low as 12.25W and sub-1W power in low-load idle states.

Ecosystem and Real-World Deployment

As of mid-2026, dozens of companies have launched products based on the 3B6000M, including laptops (such as the Lenovo Kaitian X5d G1d and the Huafang Chaorui T40-L60B), industrial controllers, all-in-one PCs, cloud terminals, and mini-PCs. Notably, in early 2026, the 3B6000M became the first fully domestic chip to successfully run the OpenClaw open-source AI agent locally, demonstrating its viability as a platform for on-device AI applications without reliance on cloud services or foreign hardware.

The 3B6000M and its sibling chip, the 2K3000 (which shares the same silicon but is packaged differently for industrial control applications), complete Loongson's product lineup alongside the 3A6000 desktop CPU and the 3C6000 server CPU series—covering desktop, server, and terminal segments with a unified, fully (self-controlled) architecture.
