When to Choose the L40S
The L40S suits workloads that require the 48 GB VRAM capacity and the 362.05 TFLOPS dense FP16 rating. Its 864 GB/s bandwidth further supports sustained throughput in large scale inference or training sessions.
When to Choose the RTX 4080
The RTX 4080 fits tasks where the 320 W TDP rating and 16 GB VRAM configuration meet the scale of the workload. Its 97.5 TFLOPS dense FP16 rating remains adequate for smaller inference jobs.
Use Cases
The L40S supplies 48 GB VRAM and 362.05 TFLOPS dense FP16 which exceed the 16 GB and 97.5 TFLOPS on the RTX 4080.
The L40S provides 733 TFLOPS FP8 with sparsity and 48 GB memory that allow larger batch handling than the 389.8 TFLOPS and 16 GB on the RTX 4080.
The L40S offers 733 TOPS INT8 dense and 864 GB/s bandwidth that support efficient parameter updates beyond the 389.9 TOPS and 717 GB/s on the RTX 4080.
The RTX 4080 operates at 320 W TDP with sufficient 97.5 TFLOPS dense FP16 for typical image generation scales.
The L40S achieves 91.6 TFLOPS FP32 and 48 GB VRAM which surpass the 48.7 TFLOPS and 16 GB on the RTX 4080.

How this page is made
- Specifications come from the NVIDIA, AMD and Intel datasheets for the L40S and the RTX 4080. 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.
