While Loongson has been known for their MIPS-based Loongson chips that are open-source friendly and have long been based on MIPS, with MIPS now being a dead-end, the Chinese company has begun producing chips using its own “LoongArch” ISA. The first Loongson 3A5000 series hardware was just announced and thanks to the company apparently using the Phoronix Test Suite and OpenBenchmarking.org we have some initial numbers.
Announced this week was the Loongson 3A5000 as their first LoongArch ISA chip that is quad-core with clock speeds up to 2.3~2.5GHz. Loongson 3A5000 offers a reported 50% performance boost over their prior MIPS-based chips while consuming less power and now also supporting DDR4-3200 memory. The Loongson 3A5000 series is intended for domestic Chinese PCs without relying on foreign IP and there is also the 3A5000LL processors intended for servers.
Performance isn’t even remotely interesting – for now. The Loongson processors will improve by leaps and bounds over the coming years, if only because it will have the backing of the regime. I hope some enterprising people import these to the west, because I’d love to see them in action. Nothing in technology excites me more than odd architectures.
