Why Engineers Prefer Rockchip Single Board Computers
Rockchip processors are popular in embedded computing because of their high efficiency, robust multimedia support, and AI acceleration. Here, we outline the main reasons why developers and engineers prefer Rockchip-based SBCs.
1. Performance and Power Efficiency
Rockchip’s newest SoCs, including the RK3588 and RK3399, are fabricated with advanced process nodes like 8nm FinFET and include features such as:
- Octa-core CPU configurations (e.g., 4x Cortex-A76 + 4x Cortex-A55) for optimal multitasking.
- ARM Mali GPUs (e.g., Mali-G610) supporting OpenGL ES 3.2, Vulkan 1.2, and OpenCL 2.0 for graphics and compute workloads.
- Dedicated NPUs (Neural Processing Units) for AI acceleration, such as the 6 TOPS NPU in the RK3588.
- Hardware-accelerated video codecs (8K@60fps H.265/VP9, 4K@60fps AV1) for multimedia applications.
Compared to alternatives like Raspberry Pi (Broadcom) or Allwinner-based boards, Rockchip SBCs provide superior AI inference capabilities and multimedia performance while maintaining low power consumption.
2. Key Applications of Rockchip SBCs
Rockchip-based boards are versatile and used across multiple industries.
- AI & Edge Computing: The integrated NPU enables real-time object detection, facial recognition, and natural language processing.
- Digital Signage & Media Players: 8K video playback and multi-display support make them ideal for advertising and entertainment systems.
- Industrial Automation: Robust I/O (CAN, SPI, UART) and wide operating temperature ranges suit factory automation and robotics.
- IoT Gateways: With WiFi 6, Bluetooth 5.4, and Gigabit Ethernet, Rockchip SBCs serve as high-performance edge nodes.
3. Spotlight on the Kiwi Pi 5: A High-Performance Rockchip SBC

Comparison: Rockchip SBCs vs. Competing Solutions
To better understand where Rockchip SBCs excel, let’s compare them to popular alternatives:
| Criteria | Rockchip SBCs (e.g., Kiwi Pi 5) | Raspberry Pi 5 | NVIDIA Jetson Nano |
|---|---|---|---|
| CPU Performance | High (Octa-core A76/A55) | Moderate (Quad-core A76) | Moderate (Quad-core A57) |
| GPU/Acceleration | Mali-G610 + NPU | VideoCore VII | 128-core Maxwell GPU |
| AI Capabilities | 6 TOPS NPU (On-board) | None | 472 GFLOPS (GPU-based) |
| Video Playback | 8K@60fps | 4K@60fps | 4K@60fps |
| Power Efficiency | Excellent (8nm process) | Good (16nm) | Moderate (20nm) |
| Best For | AI, 8K media, industrial use | Hobbyist projects | Robotics, AI prototyping |
Key Takeaways
- Rockchip SBCs lead in AI and multimedia due to dedicated NPUs and advanced video codecs.
- Raspberry Pi is more accessible for beginners but lacks AI acceleration.
- Jetson Nano offers CUDA support but is less power-efficient than Rockchip solutions.
