RK3566 vs RK3568 for Smart Home Control Panels: Which One is More Suitable?

When selecting a processor for smart home control panels, performance, power efficiency, and compatibility with embedded systems are key considerations. Rockchip’s RK3566 and RK3568 are two popular options used in Portworld’s range of smart home panels and embedded PCBA solutions. Here is a detailed comparison from the perspective of smart home applications and PCBA design.

1. Basic Specifications Comparison

Feature RK3566 RK3568
CPU Architecture Quad-core Cortex-A55 Quad-core Cortex-A55 + optional Cortex-A76 (higher performance)
GPU Mali-G52 Mali-G52 / G610 (depending on model)
Maximum Memory LPDDR4 / LPDDR4x LPDDR4 / LPDDR4x / LPDDR5
Video Codec H.264 / H.265 H.264 / H.265, supports 4K@60fps high bitrate
Industrial Design Supported Supported, higher frequency options available

Summary: RK3568 offers higher CPU/GPU performance, more memory options, and better 4K video processing capability compared to RK3566.

2. Smart Home Application Considerations

  1. Home Automation Tasks

  • RK3566: Adequate for running Home Assistant, controlling lighting, curtains, HVAC, door locks, and other smart devices. Supports multiple protocols such as RS485, Zigbee, and KNX. Suitable for typical UI resolutions below 1080p.
  • RK3568: Better suited for high-resolution displays, multi-tasking, complex UI animations, and 4K video playback. Ideal for advanced smart home panels and digital signage.
  1. Display Panel Compatibility

  • RK3566: Recommended for 4–10 inch small to mid-size panels, offering smooth UI performance at a lower cost.
  • RK3568: Ideal for 10–14 inch or larger panels, handling higher resolution interfaces and more complex tasks.
  1. Power Consumption & Cost

  • RK3566: Lower power consumption and cost, suitable for mass-market, cost-sensitive smart home panels.
  • RK3568: Slightly higher power consumption and cost, but provides high performance for demanding applications.

3. PCBA Design Considerations

  1. Layout & Size

  • RK3566 PCB: Compact and space-efficient, perfect for 86-type wall-mounted panels or small embedded devices.
  • RK3568 PCB: Slightly larger, may require enhanced heat dissipation for medium to large screens.
  1. Interfaces & Expansion

  • RK3566: Standard interfaces such as LVDS/eDP, Ethernet, Wi-Fi, USB are sufficient for most smart home control needs.
  • RK3568: Supports higher memory frequency, more interfaces, and better expansion for industrial or high-performance applications.
  1. Customization / OEM Options

  • Both processors support OEM/ODM customization, but RK3568 is better suited for high-performance panels requiring multi-screen display, 4K video decoding, or complex UI applications.
