How to Choose Between RK3588, RK3576 and RK3568 SoMs: A Practical Selection Guide

RK3588, RK3576 and RK3568 are the three most commonly used Rockchip SoCs in real projects. Customers often start by asking "can we just use RK3588?" — but over-specifying inflates cost while under-specifying stalls on AI performance. Here is a practical comparison.

Key Specifications at a Glance

Choose RK3588 when...

• Multi-channel video processing: an NVR decoding 16+ IP cameras, or multi-channel AI analytics;
• Edge computing boxes: running heavy vision models (6 TOPS NPU plus plenty of CPU headroom);
• Multi-display / large-screen terminals: dual HDMI, multiple MIPI-DSI panels or 8K output.

Choose RK3576 when...

• You want near-RK3588 AI performance (also 6 TOPS) at a tighter budget;
• Single-channel 4K or multi-channel 1080p IPC / compact NVR with industrial-grade interfaces.

Choose RK3568 when...

• Cost-sensitive entry products: signage, serial-screen terminals, lightweight gateways;
• Fixed-function devices with low compute demands.

Our Advice

Selection is a balance of compute headroom × cost × supply. A proven approach: validate the mid-range on RK3576 and target the flagship with RK3588 — pin-compatible SoM families let you upgrade later without redrawing the baseboard. Hongyin Tech offers core boards and custom mainboards on all three platforms, covering both Android and Linux.
