Chinese company Loongson has been developing custom processors based on the LoongArch instruction set, a new design initiated in 2020. Phoronix reviewed the company’s 3B6000 processor, which has 12 cores supporting simultaneous multithreading (SMT2), resulting in 24 threads. The platform is compatible with DDR4 memory, with a controller targeting speeds up to 3,200 MT/s and ECC support. In testing, the 3B6000 processor achieved about one-third the performance of the AMD Ryzen 5 9600X in aggregate benchmark testing. However, it outperformed the Raspberry Pi 500+ by a factor of 2.5, placing it between single-board computers and entry-level desktop systems.
For testing, Phoronix used the 3B6000x1-7A2000x1-EVB evaluation board, which appears dated compared to current motherboard desi…

However, it outperformed the Raspberry Pi 500+ by a factor of 2.5, placing it between single-board computers and entry-level desktop systems.
For testing, Phoronix used the 3B6000x1-7A2000x1-EVB evaluation board, which appears dated compared to current motherboard designs, especially in terms of component selection and the cooling solution for the chipset. Expansion options include two PCIe x16 slots, one PCIe x4 slot, an M.2 connector, and four SATA ports. The integrated graphics unit supports both HDMI and VGA outputs. While the LoongArch64 architecture represents China’s effort to develop an independent instruction set with the ability to tune features like security and specialized workloads, these benchmarks suggest the hardware execution still lags several generations behind x86-64 designs from AMD and Intel. Significant, multifold improvements are needed before it can match the performance of Western CPU makers.
