What actually differs
Both GPUs launched in 2023: the L4 on Ada Lovelace and the L40S on Ada Lovelace.
Dense throughput for the L4 against the L40S: FP64 0.4 vs 1.4 TFLOPS, FP32 30 vs 92 TFLOPS, FP16 121 vs 362 TFLOPS, FP8 243 vs 733 TFLOPS. Sparse figures, where the vendor publishes them, appear under each dense number in the performance table.
Memory is 24 GB against 48 GB, fed at 300 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 72 W for the L4 and 350 W for the L40S. At FP32 that works out to 0.42 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.
