Both are Syslogic rugged Edge AI Box PCs built on the Jetson Orin NX. Here's the comparison on the three attributes you asked about:
| Attribute | RPC RML A4NX (GMSL) | RPC RML A4NX (PoE) |
|---|---|---|
| Ethernet ports | 2 (2.5GbE) | 6 (2.5GbE), of which 4 are PoE |
| Weight | 3,700 g | 3,800 g |
| Cellular | 4G/LTE | 4G/LTE |

In short:
- Ethernet: The PoE variant has significantly more connectivity with 6 Ethernet ports including 4 PoE ports, versus 2 on the GMSL variant. Both support 2.5GbE. syslogic.com +1syslogic.com ↗“io.max_ethernet_speed=2.5GbE”syslogic.com ↗“io.max_ethernet_speed=2.5GbE”
- Weight: The PoE variant is 100 g heavier (3,800 g vs. 3,700 g).
- Cellular: Identical — both offer 4G/LTE.
The key architectural difference behind those numbers: the GMSL variant instead provides 8 GMSL camera inputs for video pipelines, which the PoE variant trades for the higher Ethernet/PoE port count. syslogic.comsyslogic.com ↗“io.gmsl_camera_inputs=8”
