RK3576 vs RK3568
RK3576 is a big step up: 8 cores (A72 + A53) vs 4× A55, a 6 TOPS NPU vs 1 TOPS, and 4K@120 display. RK3568 still wins on PCIe 3.0 x2, ECC DDR, a mature mainline kernel and industrial-grade variants, and it is the safer pick for long-life industrial products.

FAQ
What is the difference between RK3576 and RK3568?
RK3576 is a big step up: 8 cores (A72 + A53) vs 4× A55, a 6 TOPS NPU vs 1 TOPS, and 4K@120 display. RK3568 still wins on PCIe 3.0 x2, ECC DDR, a mature mainline kernel and industrial-grade variants, and it is the safer pick for long-life industrial products.
Which has the stronger NPU, RK3576 or RK3568?
RK3576 (6 TOPS vs 1 TOPS).
Is RK3568 software compatible with RK3576?
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.
