NVIDIA RTX 2000 Ada 16GB vs NVIDIA L40 48GB

The RTX 2000 Ada is the newer part: Ada Lovelace, launched in 2024, against the L40'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 RTX 2000 Ada against the L40: FP32 12 vs 91 TFLOPS, FP16 24 vs 181 TFLOPS, FP8 48 vs 362 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 224 GB/s versus 864 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 70 W for the RTX 2000 Ada and 300 W for the L40. At FP32 that works out to 0.17 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.
