SpacemiT K3 RISC-V AI SoC

60 TOPS RISC-V AI SoC, RVA23 compliant, mainline Linux

Highlights

  • 60 TOPS INT4 from eight dedicated A100 AI cores
  • RVA23 compliant — runs Ubuntu 26.04 natively without patches
  • RK3588-class multi-core performance on an open instruction set
  • Four TSN-capable Gigabit MACs for deterministic industrial networking
  • Eight lanes of PCIe Gen3 for NVMe and accelerator expansion
  • Up to 12 camera inputs for vision AI workloads
  • Industrial temperature range and hardware virtualization
  • Mainline Linux support reduces long-term maintenance risk
