On January 29, 2026, SpacemiT, a semiconductor company based in Hangzhou, China, introduced its K3 AI CPU, which supports advanced computing for intelligent terminals and edge computing. This development comes amid a shift in the tech industry towards open-source solutions, as demand for on-device artificial intelligence rises.
The K3 chip is one of the first RISC-V AI CPUs prepared for mass production, adhering to the RVA23 specification. It boasts a maximum frequency of 2.4 GHz with eight high-performance X100 RISC-V CPU cores and offers up to 60 TOPS of AI computing power while consuming between 15 and 25 watts of power.
Designed for applications requiring high computing density, the K3 can support AI models with parameters ranging from 30 to 80 billion. It aims for compatibility across major AI frameworks and Linux distributions, promoting a collaborative software environment.
Founded in 2021, SpacemiT is one of the few firms in China pursuing a purely RISC-V strategy, merging general computing with AI capabilities within a single chip framework.
