The Jetson TX2 Developer Kit has more CUDA cores and more memory. The Jetson Nano Developer Kit uses less power, which may matter more on a battery-powered rover.
Jetson Nano vs. Jetson TX2 Developer Kit developer... +1developer.nvidia.com ↗“compute.gpu_cuda_cores=128”developer.nvidia.com ↗“compute.gpu_cuda_cores=256”
| Spec | Jetson Nano Developer Kit | Jetson TX2 Developer Kit |
|---|---|---|
| CUDA cores (GPU type) | 128 (Maxwell) | 256 (Pascal) |
| Memory | 4 GB LPDDR4 | 8 GB LPDDR4 |
| Memory bandwidth | 25.6 GB/s | 59.7 GB/s |
| Power range | 5–10 W | 7.5–15 W |
What this means for a rover:
- Nano: Its power range starts and ends lower (5–10 W vs. 7.5–15 W), so it should be easier on a small battery. It's an entry-level kit meant for learning and building first versions of edge AI projects. developer...developer.nvidia.com ↗“Entry-level dev kit on Jetson Nano”
- TX2: It has more GPU and memory capacity, which may help if you run heavier vision or several models at once. In return, it uses more power. It's described as a legacy kit with a full set of connectors on its board. developer...developer.nvidia.com ↗“Legacy dev kit on Jetson TX2”
Note: Both kits are listed as end-of-life (EOL), so they may be harder to buy new and get long-term support for. developer... +1developer.nvidia.com ↗“identity.lifecycle_status=EOL”developer.nvidia.com ↗“identity.lifecycle_status=EOL”
