Ky X1 is closely related to SpacemiT K1 (8× X60-class cores, widely believed to be a rebrand, though the vendor has not confirmed it), so Bianbu K1 images cannot simply be reused.

Pitfalls

  • Ubuntu 24.04 uses the vendor 6.6 kernel (orange-pi-6.6-ky), not mainline; upgrade the kernel with care
  • "2 TOPS" is fused CPU compute with no dedicated NPU, so LLMs run on CPU/RVV only
  • Real-world 8-core performance is still low (Phoronix and others rate it below a contemporary 4-core ARM board), so it is no desktop workhorse
  • Official images are hosted on Google Drive, which is awkward from China; eMMC needs a separately purchased module
