What actually differs
Both GPUs launched in 2020: the GeForce RTX 3090 on Ampere and the RTX A6000 on Ampere.
Dense throughput for the GeForce RTX 3090 against the RTX A6000: FP64 0.6 vs 0.6 TFLOPS, FP32 36 vs 39 TFLOPS, FP16 71 vs 155 TFLOPS. Sparse figures, where the vendor publishes them, appear under each dense number in the performance table.
Memory is 24 GB against 48 GB, fed at 936 GB/s versus 768 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 350 W for the GeForce RTX 3090 and 300 W for the RTX A6000. At FP32 that works out to 0.10 against 0.13 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.
