Here's how the two WOLF Advanced Technology IGX Thor 3U VPX boards compare on the three attributes you asked about:
WOLF-16T1 vs WOLF-16T9 Comparison
| Attribute | WOLF-16T1 (VPX3U-THOR-SBC) | WOLF-16T9 (VPX3U-THOR-RD) |
|---|---|---|
| Fastest Ethernet | 25GbE | 10GbE |
| Weight | 1500 g | 1000 g |
| Cooling | Conduction | Conduction |
Ethernet: The WOLF-16T1 is faster, supporting up to 25GbE Ethernet , while the WOLF-16T9 tops out at 10GbE — the RD variant's description specifically calls out dual 10GBASE-KR . wolfadvanc... +2wolfadvancedtechnology.com ↗“io.max_ethernet_speed=25GbE”wolfadvancedtechnology.com ↗“io.max_ethernet_speed=10GbE”wolfadvancedtechnology.com ↗“dual 10GBASE-KR”

In short: the WOLF-16T1 offers the faster Ethernet (25GbE vs 10GbE) but is 500 g heavier; the two are identical on conduction cooling. Note that the 10GbE figure for the WOLF-16T9 aligns with its rapid-development focus (PCIe Gen5 x4, 60–140 W power range), while the WOLF-16T1 targets safety-certifiable deployments with its ISO 26262 PCIe Gen4 switch and TSN Ethernet.
