The RK3568 and RK3588 both belong to Rockchip’s product lines targeting the AIoT and industrial markets. They are often compared in scenarios such as NVR and edge computing. The key differences can be summarized as follows:
| Comparison Dimension | RK3568 | RK3588 |
|---|---|---|
| Positioning | Mid-to-high-end general-purpose SoC with a balance between performance and power consumption | High-performance flagship SoC with greater computing power |
| CPU | Quad-core Cortex-A55 | More powerful multi-core heterogeneous architecture |
| NPU Computing Power | 1 TOPS | Significantly higher, suitable for complex multi-task AI scenarios |
| Typical Application Scenarios | Conventional-channel NVR, lightweight local AI analysis, cost-sensitive projects | High-channel concurrent processing, complex multi-task AI inference, and projects with higher computing power requirements |
| Cost | Relatively lower | Relatively higher |
Simply put, if the project’s AI analysis tasks are relatively lightweight, such as facial recognition in a single scenario or simple event detection, and cost is an important consideration, the RK3568 is generally a more balanced choice. If the project needs to run multiple complex AI algorithms simultaneously and process higher-concurrency video streams, the higher computing power ceiling of the RK3588 provides more headroom. The specific hardware selection should still be evaluated comprehensively based on the actual number of channels, algorithm complexity, and budget.
