What actually differs
Both GPUs launched in 2022: the A800 on Ampere and the Jetson Orin NX on Ampere.
Dense throughput for the A800 against the Jetson Orin NX: FP32 20 vs 2.4 TFLOPS. Sparse figures, where the vendor publishes them, appear under each dense number in the performance table.
Memory is 80 GB against 8 GB, fed at 1.9 TB/s versus 102 GB/s. More memory per GPU means larger models fit before you have to shard across cards, which often matters more than raw TFLOPS for inference.
Power budgets are 300 W for the A800 and 40 W for the Jetson Orin NX. At FP32 that works out to 0.07 against 0.06 TFLOPS per watt.
For LLM training and inference, weight the FP8 and FP16 rows and memory capacity most heavily. For scientific and HPC workloads, the FP64 row is the one to read.
