What actually differs
Both GPUs launched in 2021: the Jetson AGX Orin on Ampere and the A40 on Ampere.
Dense throughput for the Jetson AGX Orin against the A40: FP32 5.3 vs 37 TFLOPS, FP16 43 vs 150 TFLOPS. Sparse figures, where the vendor publishes them, appear under each dense number in the performance table.
Memory is 64 GB against 48 GB, fed at 205 GB/s versus 696 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 60 W for the Jetson AGX Orin and 300 W for the A40. At FP32 that works out to 0.09 against 0.12 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.
