Rockchip vs NXP – How to Choose the Right Embedded SoC for Your Product

---

Selecting the right System on Chip (SoC) is one of the most important decisions a product development team can make. Whether you're building an industrial panel PC, an AI-powered gateway, or a smart HMI, the choice between Rockchip and NXP is likely to come up. These two families dominate many embedded markets—but they take very different approaches.

This article offers a concise, field-tested comparison to help teams choose wisely.

💡 When to Choose Rockchip

Rockchip SoCs are widely used in Android-based embedded products such as media players, smart panels, and human-machine interfaces.

✅ Pros:

• High performance per dollar (especially RK3566, RK3588)

• Strong multimedia capabilities (multi-display, 4K video)

• Built-in NPU for AI inference at the edge

• Broad Android BSP support

⚠️ Cons:

• Slightly less documentation in English

• Not as mature in long-term industrial life cycle management

🛡️ When to Choose NXP

NXP is often the go-to choice for industrial, medical, and automotive embedded products.

✅ Pros:

• Long-term supply chain commitment (10-15 years)

• Excellent Yocto BSP and mainline Linux support

• Rich peripheral and interface options (CAN, TSN Ethernet)

⚠️ Cons:

• Lower graphical performance

• No AI accelerator unless using Plus series

• Higher cost for comparable compute power

🔍 Bonus: Real-World Tips for SoC Evaluation

• Test the BSP out-of-the-box: Can you boot, display, and run your GUI easily?

• Check NPU/AI needs: Not all SoCs support TensorFlow Lite or ONNX well.

• Power and thermal: NXP generally runs cooler; Rockchip may need better heat management at high loads.

• Vendor support: Check how responsive the SoC vendor is for SDK/BSP help.
