RK3588 Board Review: Is This the Most Powerful ARM SBC?
The Rockchip RK3588 is currently one of the most powerful ARM-based SoCs available for single-board computers (SBCs). Designed by Rockchip, this chip targets AI edge computing, 8K multimedia, and high-performance embedded systems.
But how good is it in real-world use?
In this in-depth review, we test performance, AI acceleration, power consumption, and compare it against competitors like the Raspberry Pi 5 and Jetson Nano.
RK3588 Specifications Overview
The RK3588 is built on an 8nm process and integrates:
CPU: Quad Cortex-A76 + Quad Cortex-A55
GPU: Mali-G610 MP4
NPU: 6 TOPS AI accelerator
Video: 8K@60fps decode / 4K encode
RAM Support: LPDDR4x / LPDDR5
PCIe 3.0 Support
HDMI 2.1 Output
This makes it significantly more capable than most hobbyist SBC platforms.
