Common questions
Is the higher price of the VIM4 justified?
Yes, it includes a faster octa‑core CPU, AI NPU, HDMI‑in, Wi‑Fi 6 and a 2‑year warranty.
Can I use the Rock Pi 4 for AI workloads?
It lacks a dedicated NPU, so AI inference will be slower than on the VIM4.
Which board supports video capture?
Only the VIM4 provides HDMI‑in for capturing 4K@30 Hz video.
