FLOPS by Precision

What actually differs

The A800 is the newer part: Ampere (2022) against the Jetson AGX Orin's Ampere (2021).

The A800 carries 16 GB more memory (80 GB against 64 GB), so larger models fit on one GPU before you shard. Bandwidth is 1.9 TB/s against 205 GB/s, which sets the ceiling on decode speed.

Power is 300 W against 60 W, and at FP32 the Jetson AGX Orin does more work per watt. Weight the FP8 and FP16 rows for LLM work and the FP64 row for HPC.
