Key highlights and selection recommendations for each series are as follows:

1. Entry-level high-performance option – RK3128 series: Featuring a quad-core A7 architecture with a clock speed of up to 1.2GHz, supporting 1080P video decoding, and including basic interfaces such as HDMI, LVDS, and MIPI, this series offers low power consumption and controllable cost. Suitable for lightweight commercial scenarios with moderate performance requirements, such as simple advertising machines, small self-service kiosks, and basic human-machine interface panels, it is the top choice for high-performance entry-level commercial equipment.

2. Mainstream General-Purpose Series – RK3368/RK3288: Both are mainstream commercial models. The RK3368 uses an 8-core A53 architecture with a 1.5GHz clock speed, supports 4K@60fps H.265 decoding, and is equipped with an HDMI 2.0 interface. Balancing performance and power consumption, it is suitable for mid-to-high-end advertising displays, self-service payment machines, and other similar scenarios. The RK3288 features a 4-core A17 architecture paired with a Mali-T760 MP4 GPU, supports 4K display and dual-channel DDR, offering outstanding graphics processing capabilities. It is suitable for human-machine interaction devices requiring high-definition display and multitasking, such as industrial control screens and high-end query terminals.

3. Mid-to-High-End Performance Series – RK3568/RK3399: The RK3568, as a new generation mainstream CPU, adopts a quad-core A55 architecture, integrates a 1-TOPS NPU, supports AI acceleration, offers rich interfaces and supports multi-screen displays, boasts lower power consumption and more stable performance, making it suitable for scenarios such as intelligent self-service terminals, AI interactive devices, and high-definition advertising machines, balancing performance and cost. The RK3399 adopts a dual A72 + quad A53 multi-core architecture with a maximum clock speed of 1.8GHz, paired with a Mali-T860 MP4 GPU, possessing powerful computing and graphics processing capabilities, and supporting high-speed interfaces such as PCIe 2.1 and USB 3.0, making it suitable for high-end industrial human-machine interaction, complex self-service terminals (such as vending machines and government terminals), and other scenarios with high performance requirements.
