What actually differs
Both GPUs launched in 2023: the RTX 4000 Ada on Ada Lovelace and the GeForce RTX 4090 D on Ada Lovelace.
Dense throughput for the RTX 4000 Ada against the GeForce RTX 4090 D: FP64 0.4 vs 1.1 TFLOPS, FP32 27 vs 74 TFLOPS, FP8 214 vs 294 TFLOPS. Sparse figures, where the vendor publishes them, appear under each dense number in the performance table.
Memory is 20 GB against 24 GB. 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 130 W for the RTX 4000 Ada and 425 W for the GeForce RTX 4090 D. At FP32 that works out to 0.21 against 0.17 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.
