NVIDIA GeForce RTX 4080 Super 16GB vs NVIDIA RTX 6000 Ada 48GB

The GeForce RTX 4080 Super is the newer part: Ada Lovelace, launched in 2024, against the RTX 6000 Ada's Ada Lovelace from 2023. Newer architectures typically add lower-precision formats and better throughput per watt, so check the precision rows your workload actually uses.

Dense throughput for the GeForce RTX 4080 Super against the RTX 6000 Ada: FP32 52 vs 91 TFLOPS, FP8 209 vs 729 TFLOPS. Sparse figures, where the vendor publishes them, appear under each dense number in the performance table.

Memory is 16 GB against 48 GB, fed at 736 GB/s versus 960 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 320 W for the GeForce RTX 4080 Super and 300 W for the RTX 6000 Ada. At FP32 that works out to 0.16 against 0.30 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.
