Performance Analysis
The L40S supplies double the dense FP16 performance at 362.05 TFLOPS relative to 181.05 TFLOPS on the L40. This ratio permits the L40S to finish dense FP16 matrix calculations in half the duration during training workloads. Sparse FP16 performance maintains a comparable ratio at 733 TFLOPS on the L40S versus 362.1 TFLOPS on the L40. Memory bandwidth stays fixed at 864 GB/s on both units. Identical bandwidth keeps maximum batch sizes limited by the same transfer rate in memory intensive operations. FP32 performance exhibits little change at 91.6 TFLOPS versus 90.5 TFLOPS. The 350W TDP rating on the L40S accommodates its elevated tensor rates while the L40 functions at 300W.

How this page is made
- Specifications come from the NVIDIA, AMD and Intel datasheets for the L40 and the L40S. Dense and sparse throughput are listed separately.
- Prices and availability are live: every offer shown is an in-stock, on-demand listing from a provider we track, rechecked every minute.
- The written comparison (overview, performance notes, when to choose each card, verdict, use cases and FAQ) was drafted with an AI model from the specification table above and passed an automated check that rejects any figure not in that table. It was last generated on . It contains no prices; those are always read live.
