Here's how the two Realtimes carrier boards compare on those three attributes:
| Product | CAN ports | Ethernet ports | Fastest Ethernet speed |
|---|---|---|---|
| RTSO-4006 | 4 | 3 | 10GbE |
| RTSO-4007 | 7 | 2 | 25GbE |

- CAN ports: The RTSO-4007 has more CAN ports than the RTSO-4006. Note that the RTSO-4007's CAN capability is module-dependent — seven CAN ports when paired with the Jetson Thor T5000, or three with the T4000 — while the RTSO-4006 lists 4 CAN ports. realtimesa... +1realtimesai.com ↗“seven for T5000 or three for T4000”realtimesai.com ↗“io.can_port_count=4”
- Ethernet ports: The RTSO-4006 offers three Ethernet ports to the RTSO-4007's two. The RTSO-4007's two interfaces are specified as 25GbE SFP28 interfaces plus two Ethernet IX connectors per its product description. realtimesa... +2realtimesai.com ↗“io.ethernet_ports=3”realtimesai.com ↗“io.ethernet_ports=2”realtimesai.com ↗“two 25GbE SFP28 interfaces and two Ethernet IX connectors”

In short: choose the RTSO-4007 if you need maximum CAN count and higher per-port Ethernet bandwidth; the RTSO-4006 gives you one more Ethernet port but caps at 10GbE.
