FAQ
What is the difference between RV1106 and RV1126?
Both are vision SoCs. RV1106 is tiny and cheap (single A7, up to 1 TOPS, in-package DDR, 5 MP ISP), ideal for low-cost smart cameras. RV1126 has 4× A7, a 2 TOPS NPU, a 14 MP ISP and 4K encode for higher-end AI cameras and face-recognition terminals.
Which has the stronger NPU, RV1106 or RV1126?
RV1126 (2 TOPS vs 1 TOPS).
Is RV1126 software compatible with RV1106?
Both use Rockchip's BSP stack (U-Boot, vendor kernel, RKNN where an NPU exists), so application code ports easily. Device trees, DDR init blobs and some drivers are SoC-specific and must be adapted.
