What actually differs
Both GPUs launched in 2020: the GeForce RTX 3080 on Ampere and the A100 on Ampere.
Dense throughput for the GeForce RTX 3080 against the A100: FP64 0.5 vs 9.7 TFLOPS, FP32 30 vs 20 TFLOPS, FP16 60 vs 312 TFLOPS. Sparse figures, where the vendor publishes them, appear under each dense number in the performance table.
Memory is 10 GB against 40 GB, fed at 760 GB/s versus 1.6 TB/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 320 W for the GeForce RTX 3080 and 250 W for the A100. At FP32 that works out to 0.09 against 0.08 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.
