RK3588 vs RK3568: Full Specification & Application Selection Guide
Introduction
Rockchip RK3588 and RK3568 are two mainstream embedded SoCs widely adopted in industrial control, edge AI computing, smart display, and IoT terminal projects. Although both chips belong to Rockchip’s high-performance IoT processor lineup, they feature completely different market positioning, hardware architecture, computing power, video processing capabilities, and industrial adaptability.
TheRK3568 is a cost-effective mid-range quad-core processor designed for stable operation, low power consumption, and mass production. It supports industrial-grade wide-temperature versions (RK3568J) and has been massively deployed in industrial gateways, HMI human-machine terminals, 4K commercial displays, and general IoT devices. With mature software ecology, sufficient market stock, and low BOM cost, it remains the preferred solution for cost-sensitive embedded projects.
In contrast, the RK3588 is Rockchip’s flagship 8nm octa-core high-end SoC. Equipped with a big.LITTLE architecture (4×Cortex-A76 + 4×Cortex-A55), upgraded Mali-G610 GPU, 6TOPS high-power NPU, 8K ultra-high-definition video decoding and encoding, and high-speed industrial interfaces such as PCIe 3.0 and 10G Ethernet expansion, it is specially built for high-load edge AI reasoning, multi-channel video analysis, 8K ultra-HD display, and high-performance industrial computing scenarios.
It is worth emphasizing that RK3588 and RK3568 are not pin-to-pin compatible. Direct chip replacement is not feasible. Engineers must comprehensively evaluate CPU performance, AI computing power, video resolution requirements, interface expansion, power consumption heat dissipation, and project budget during hardware selection to avoid subsequent performance bottlenecks and secondary hardware modifications.
Core Technical Differences Between RK3588 and RK3568
1. CPU & GPU Architecture and Overall Performance
Rockchip RK3568 adopts a pure quad-core Cortex-A55 architecture with a main frequency of up to 2.0GHz. Equipped with Mali-G52-2EE GPU, it delivers stable and power-efficient computing capability. This configuration fully meets lightweight system operation, simple UI rendering, conventional industrial data collection, and routine logic processing. Its power consumption and performance balance are very suitable for long-term standby and 7×24-hour stable operation of general industrial equipment.
Rockchip RK3588 uses a heterogeneous octa-core big.LITTLE design: 4 high-performance Cortex-A76 cores (up to 2.4GHz) + 4 energy-efficient Cortex-A55 cores (up to 1.8GHz). Paired with Mali-G610 MP4 high-end GPU, its comprehensive CPU performance is approximately three times that of the RK3568. The stronger graphics rendering capability supports complex 3D UI interfaces, multi-task concurrent processing, and high-load system operation, perfectly matching high-end industrial hosts and intelligent visual devices with high-performance requirements.
2. NPU Edge AI Computing Power
RK3568 NPU: 1TOPS INT8
The built-in NPU of RK3568 only supports lightweight artificial intelligence inference. It can handle basic algorithm tasks such as static face recognition, simple target detection, and human body induction. However, due to limited computing power, it cannot support multi-channel camera parallel analysis, complex image segmentation algorithms, or local deployment of small and medium-sized AI models. It is only suitable for low-level AI auxiliary scenarios.
RK3588 NPU: 6TOPS INT8
RK3588’s 6TOPS high-power NPU supports INT4/INT8/FP16 multi-precision operation. It stably runs multi-target detection, defect segmentation, posture analysis, and other complex visual algorithms. It supports simultaneous reasoning of multiple AI models and multi-channel video stream analysis, becoming the mainstream cost-effective solution for industrial machine vision and local edge large model deployment.

It supports maximum 32GB large-capacity memory expansion, suitable for high-speed SSD storage, multi-network port data gateways, and high-performance edge computing boxes requiring large bandwidth transmission.
6. Power Consumption, Heat Dissipation and Project Cost
RK3568 features ultra-low power consumption design, with full-load power consumption controlled at 3–5W. Most application scenarios can adopt fanless passive heat dissipation, no complex heat dissipation structure is required. The overall BOM cost is low, which is very friendly for mass production. The industrial version RK3568J supports -40℃~+85℃ wide-temperature operation, adapting to harsh industrial workshop environments.
RK3588 has stronger overall performance but higher power consumption, with full-load power consumption ranging from 5–10W. When NPU computing and multi-channel video decoding are running at full load, heat generation increases significantly. It is recommended to configure heat sinks or active heat dissipation structures. The chip unit price and overall project cost are higher, suitable for mid-to-high-end equipment with mandatory performance indicators.

Q3: Does RK3588 must use a fan for heat dissipation?
A3: Under daily low-load operation, passive heat dissipation with heat sinks is sufficient. However, when running full-load NPU reasoning and multi-channel 8K video decoding simultaneously, the power consumption and heat generation will increase sharply. For long-term high-load industrial scenarios, active heat dissipation is recommended to ensure stable operation.
