What actually differs
The L20 is the newer part: Ada Lovelace, launched in 2024, against the RTX 5000 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 L20 against the RTX 5000 Ada: FP32 60 vs 65 TFLOPS, FP8 239 vs 522 TFLOPS. Sparse figures, where the vendor publishes them, appear under each dense number in the performance table.
Memory is 48 GB against 32 GB, fed at 864 GB/s versus 576 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 275 W for the L20 and 250 W for the RTX 5000 Ada. At FP32 that works out to 0.22 against 0.26 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.
