Performance Analysis
The L40S delivers 362.05 TFLOPS dense FP16 compared with 58.3 TFLOPS dense FP16 on the RTX 4070. This sixfold difference in dense FP16 throughput indicates the L40S supports substantially higher throughput for mixed precision training and inference workloads that rely on dense FP16 operations. The RTX 4070 reaches 116.6 TFLOPS FP16 with sparsity while the L40S reaches 733 TFLOPS FP16 with sparsity so the same ratio holds when sparsity is applied. Memory bandwidth of 864 GB/s on the L40S versus 504 GB/s on the RTX 4070 permits larger batch sizes during training or inference before memory capacity or transfer limits are reached.

When to Choose the L40S
The L40S suits workloads that require 48 GB VRAM and 362.05 TFLOPS dense FP16 throughput. Its 864 GB/s bandwidth and 91.6 TFLOPS FP32 performance enable handling of large models that exceed the 12 to 16 GB capacity of the RTX 4070.
When to Choose the RTX 4070
The RTX 4070 suits deployments constrained to 200W TDP where 58.3 TFLOPS dense FP16 and 504 GB/s bandwidth remain sufficient. Its lower power draw compared with the 350W TDP of the L40S fits compact systems that do not need 48 GB VRAM.
Use Cases
The L40S supplies 48 GB VRAM and 362.05 TFLOPS dense FP16 while the RTX 4070 supplies only 12 to 16 GB and 58.3 TFLOPS dense FP16.
The L40S supplies 733 TFLOPS FP16 with sparsity and 864 GB/s bandwidth that exceed the 116.6 TFLOPS FP16 with sparsity and 504 GB/s bandwidth of the RTX 4070.
The L40S supplies 48 GB VRAM together with 362.05 TFLOPS dense FP16 that accommodate larger fine tuning batches than the 12 to 16 GB and 58.3 TFLOPS dense FP16 of the RTX 4070.
Both GPUs share the Ada Lovelace architecture and the RTX 4070 58.3 TFLOPS dense FP16 suffices for many diffusion workloads while the L40S 362.05 TFLOPS dense FP16 handles higher resolution or batch counts.
The L40S supplies 91.6 TFLOPS FP32 and 733 TFLOPS FP8 with sparsity that exceed the 29.1 TFLOPS FP32 and 116.6 TFLOPS FP8 with sparsity of the RTX 4070.

How this page is made
- Specifications come from the NVIDIA, AMD and Intel datasheets for the L40S and the RTX 4070. 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.
