In the field of industrial embedded computing and edge AI, SMA3576 and SMA3588 are two high-performance SMARC 2.2 computer-on-modules widely used in smart industrial devices, edge servers, and AI vision systems.
These two modules are respectively based on the Rockchip RK3576J and Rockchip RK3588J processors. Both chips adopt an 8nm process, feature an octa-core big.LITTLE architecture, and integrate a 6 TOPS NPU for AI acceleration.
Manufacturers such as Shenzhen Beilai Technology Co., Ltd. package these processors into fully compatible SMARC 2.2 modules, making them easy to integrate into industrial embedded systems.
Typical module features include:
Form Factor: 82 × 50 mm
Connector: MXM3.0 314-pin
Memory: LPDDR5
Storage: eMMC
Networking: Dual Gigabit Ethernet
Camera: Dual MIPI CSI
Display: HDMI / eDP / MIPI-DSI
Operating Temperature: -40°C to +85°C
At first glance, the specifications appear almost identical:
Both offer 6 TOPS AI performance
Both support LPDDR5 and eMMC
Both support Linux, Android, and Ubuntu
Similar power consumption (<5W under load)
However, in real-world industrial applications, the actual performance difference can reach 30% to 100%+, mainly due to CPU architecture, GPU capability, and memory bandwidth differences.
Let’s take a deeper look.
| Feature | RK3576J | RK3588J |
|---|---|---|
| Big Cores | 4× Cortex-A72 | 4× Cortex-A76 |
| Little Cores | 4× Cortex-A53 | 4× Cortex-A55 |
| Max Frequency | ~2.2–2.4 GHz | up to 2.4 GHz |
| Cache | L2 cache | L2 + 3MB shared L3 |
| Single-Core Performance | Moderate | Strong |
| Multi-Core Performance | Good | High |
The most significant difference is CPU architecture generation:
Cortex-A72 architecture dates back to around 2015
Cortex-A76 is a modern high-performance architecture
In practical workloads such as:
Linux desktop responsiveness
Industrial protocol processing
Multi-threaded tasks
Software compilation
the RK3588J typically delivers 40–70% higher CPU performance.
For devices like:
Industrial HMI panels
Edge computing gateways
Edge servers
the performance difference becomes noticeable.
Both processors advertise 6 TOPS INT8 AI performance, but their internal architectures differ.

|---|---|---|
| GPU | Mali-G52 MC3 | Mali-G610 MP4 |
| Graphics Performance | Moderate | High |
| UI Rendering | Smooth at 1080p | Smooth even with 4K complex UI |
The RK3588J provides 60–120% stronger GPU performance, which is important for:
Advanced Qt / Flutter HMI interfaces
Digital signage systems
Multi-display industrial terminals
Interactive visualization dashboards
Video performance is another area where RK3588J stands out.
| Feature | RK3576J | RK3588J |

| Encoding | 4K@60fps | 4K@60fps |
| Codec Support | H.264 / H.265 | H.264 / H.265 / AV1 |
This makes RK3588J more suitable for:
8K digital signage
Video conferencing systems
AI NVR systems
Smart surveillance analytics
From a SMARC 2.2 module design perspective, both modules share highly compatible pinouts, but RK3588J enables more high-speed capabilities.
| Interface | RK3576J | RK3588J |
|---|---|---|
| USB | 1× USB3.0 | Up to 2× USB3.0 |
| PCIe | Limited lanes | More flexible lane configuration |
| Display | HDMI / DSI | HDMI / DSI / DisplayPort |
| Storage | eMMC | eMMC + NVMe possible |
This allows RK3588J systems to support:
Wi-Fi 6 modules
NVMe SSD storage
10Gb Ethernet adapters
AI accelerator cards
| Feature | RK3576J | RK3588J |
|---|---|---|
| Typical Load Power | 3.5–4.5W | 4–5W |
| Cooling Requirement | Similar | Similar |
| Cost | Lower | Higher |
Typically, RK3576J modules are about 25–40% cheaper than comparable RK3588J modules.
This makes RK3576J attractive for cost-sensitive industrial products.
| Application | Recommended Platform | Reason |
|---|---|---|
| Cost-sensitive industrial HMI | RK3576J | Best price/performance |
| Mid-range AI NVR | RK3576J | AI capability is sufficient |

Although both processors offer 6 TOPS AI performance on paper, their real-world capabilities are significantly different.
RK3576J is an excellent cost-effective industrial AI processor, ideal for:
Industrial gateways
Moderate AI workloads
Cost-sensitive embedded systems
Meanwhile, RK3588J is a true flagship edge AI processor, offering:
