Deep Comparison Between RK3576J and RK3588S Processors
Rockchip' s RK3576J and RK3588S are two high-performance processors designed for different application scenarios, each offering unique advantages in industrial computing and intelligent edge deployments.
The RK3576J, with its heterogeneous Cortex-A72 + A53 architecture and built-in Cortex-M0 real-time core, excels in real-time demanding applications such as industrial control and in-vehicle electronics.
On the other hand, the RK3588S, built on a more advanced 8nm process and featuring a Cortex-A76 + A55 architecture, delivers remarkable improvements in multimedia processing and AI performance. This makes it particularly suitable for edge servers and smart terminals requiring high-performance computing.
Both processors are equipped with a 6 TOPS NPU, but in practice, the RK3588S benefits from a larger cache and higher memory bandwidth, providing superior efficiency in handling complex AI models.
Based on these processors, BLIIoT has developed the BL440 Edge Gateway (RK3576J) and BL450 Edge Server (RK3588S), delivering complete hardware solutions tailored to different customer needs. Users can select the optimal product depending on computing requirements, environmental conditions, and budget.
