Loonies for Loongsons

10 hours ago

The article details getting a salvaged Loongson 3A5000-based motherboard (ML5A-MB1) running with Linux, exploring its performance and compatibility.
Loongson Technology develops its own CPU architecture called LoongArch, distinct from x86, ARM, or PowerPC, used in various Chinese systems.
The motherboard was acquired for about $50 plus shipping from a Chinese salvage market, requiring a cooler, RAM, storage, and an OS.
A standard Intel 1155 cooler fit the motherboard, indicating reuse of common components, and Debian was installed after a BIOS update.
Performance benchmarks show the Loongson 3A5000LL lags behind a 2012 Intel i5-3570 but beats a 2007 Core Quad Q6600, placing in the 13th percentile overall.
The system ran games like Doom II and Quake adequately and handled YouTube via Firefox, with video output via an integrated Loongson 7A1000 GPU based on Vivante GC1000.
Despite its unique architecture, the system feels normal due to adherence to standards like USB, PCIe, and UEFI, with Linux portability making it functional.
Challenges included initial boot issues, Wi-Fi adapter compatibility problems, and package conflicts in Debian, but overall, it provides a usable Linux environment.
