The IGX Thor Developer Kit comes out ahead on all three: faster Ethernet (200GbE vs 25GbE), twice as many SFP-type ports (2 vs 1) and about 2.7× the FP4 throughput (5581 vs 2070 FP4 TFLOPS).

|---|---|---|
| Max Ethernet speed | 25GbE | 200GbE |
| SFP ports | 1 | 2 (2x QSFP112 200GbE via ConnectX-7) |
| FP4 performance | 2070 FP4 TFLOPS | Up to 5581 FP4 TFLOPS (sparse) |
About these figures:
- Ethernet / SFP: The IGX kit gets its 200GbE ports from a ConnectX-7 adapter with 2x QSFP112 cages. nvidia.comnvidia.com ↗“ConnectX-7 (2x QSFP112 200GbE)”
- FP4, IGX: The IGX figure includes the pre-installed RTX PRO 6000 Blackwell Max-Q dGPU. It is a sparse figure. Power is 40–130 W for the IGX T7000 board kit, plus up to 300 W for the dGPU. nvidia.com +1nvidia.com ↗“pre-installed RTX PRO 6000 Blackwell Max-Q dGPU”nvidia.com ↗“Power 40-130 W TMP for the IGX T7000 board kit, up to 300 W for the dGPU”
- FP4, Jetson: The Jetson kit's 2070 FP4 TFLOPS comes from its Jetson AGX Thor T5000 module. I couldn't find whether that figure is sparse or dense, so the two FP4 numbers may not be measured the same way. developer...developer.nvidia.com ↗“Jetson AGX Thor T5000 (Blackwell, 2070 FP4 TFLOPS, 128GB)”
Other differences that may matter for surgical robotics:
- Safety: The IGX Thor Developer Kit has a BMC, a functional safety island and a safety MCU. nvidia.comnvidia.com ↗“BMC, functional safety island and safety MCU”
- Memory: The IGX kit adds 96GB of GDDR7 on top of its 128GB LPDDR5X. The Jetson kit has 128GB. nvidia.comnvidia.com ↗“128GB LPDDR5X plus 96GB GDDR7”
- Positioning: The Jetson AGX Thor Developer Kit is a reference kit for humanoid and robotics prototyping. It includes Holoscan Sensor Bridge and JetPack 7.
