SpacemiT Unveils 16-Core RISC-V Mini Desktop Powered by K3 Chip
SpacemiT showcased its new K3 RISC-V System-on-Chip (SoC) in a compact desktop, featuring 16 cores for CPU and AI tasks. This development is significant as it provides the first commercially available hardware supporting the RVA23 specification, enabling full Ubuntu OS operation on RISC-V architecture.
Key points
- SpacemiT demonstrated its Key Stone K3 chip, a 16-core RISC-V SoC with 8 X100 CPU cores and 8 A100 AI cores.
- The K3 chip supports the RVA23 specification, a major RISC-V milestone offering vector math acceleration and hypervisor capabilities.
- This is the first commercially available hardware confirmed to ship with RVA23 support.
- Full Ubuntu GNOME 25.10 'Questing Quokka' has been successfully run on the K3 hardware, previously only possible via emulation.
- Canonical, the company behind Ubuntu, announced support for the RVA23 SoC in February, recognizing its importance.
SpacemiT has revealed its Key Stone K3 System-on-Chip (SoC), integrated into a mini desktop form factor, at the recent Ubuntu Summit. The chip boasts a substantial 16-core configuration, comprising eight of SpacemiT's proprietary X100 CPU cores clocked up to 2.4 GHz and eight dedicated A100 AI cores.
This launch marks a significant step for the RISC-V architecture, as the K3 chip is the first commercially available hardware to fully support the RVA23 specification. RVA23, recognized by the RISC-V International association as a major milestone, integrates advanced features like full vector math acceleration and hypervisor capabilities. Previously, running the RISC-V edition of Ubuntu 25.10 "Questing Quokka" required emulation, as no compatible hardware was available.
Canonical, the developers of Ubuntu, had announced support for the RVA23 SoC back in February, acknowledging its potential. The demonstration at the Ubuntu Summit showcases full Ubuntu GNOME operating on the K3 hardware, moving beyond emulation and indicating a new era for RISC-V in desktop computing.
