**No, only the AIE-KT78 has CAN bus. It also has the higher FP4 figure: 2070 TFLOPS, compared with 1200 TFLOPS on the AIE-KT68.**

**AIE-KT68 vs AIE-KT78**

| | AIE-KT68 | AIE-KT78 |
|---|---|---|
| CAN bus | No | Yes, 2 ports |
| Max FP4 TFLOPS | 1200 | 2070 |
| Jetson module | Jetson T4000 64GB | Jetson T5000 128GB |

- **CAN bus:** The maker says CAN FD is only available on the AIE-KT78. The AIE-KT78 has 2 isolated CAN FD ports.
- **FP4 performance:** Both are FP4 figures, so you can compare them directly. They come from the Jetson Thor module in each system.
- **Datasheet status:** Aetina's datasheet for both systems is marked Preliminary, so these specs may still change.
