Performance Analysis
The FP16 dense performance of the L40 reaches 181.05 TFLOPS compared to 61.7 TFLOPS dense on the RTX 5070. The FP16 figure with sparsity stands at 362.1 TFLOPS for the L40 against 123.5 TFLOPS with sparsity for the RTX 5070. The FP32 rating of 90.5 TFLOPS on the L40 yields a two times ratio to its dense FP16 value while the RTX 5070 maintains the same two times ratio between its 30.9 TFLOPS FP32 and 61.7 TFLOPS dense FP16. Memory bandwidth of 864 GB/s on the L40 exceeds the 672 GB/s on the RTX 5070 and therefore supports larger batch sizes in memory intensive operations. The FP8 dense rating of 362 TFLOPS on the L40 compares directly to 123.5 TFLOPS dense on the RTX 5070 while the corresponding sparsity figures are 724 TFLOPS and 246.9 TFLOPS.

When to Choose the L40
The L40 suits workloads that demand 48 GB of memory such as training models that exceed the 12 GB to 16 GB capacity of the RTX 5070. Its 864 GB/s bandwidth further enables sustained data movement in large batch inference scenarios where the 300 W TDP remains acceptable.
When to Choose the RTX 5070
The RTX 5070 fits environments that prioritize 250 W power draw and PCIe 5.0 interconnect over maximum memory size. Its Blackwell architecture supports FP4 dense performance of 493.9 TFLOPS for emerging low precision tasks that fit within 12 GB to 16 GB.
Use Cases
The L40 supplies 48 GB of memory that exceeds the 12 GB to 16 GB limit of the RTX 5070 and therefore handles larger training batches.
The L40 delivers 181.05 TFLOPS dense FP16 that surpasses the 61.7 TFLOPS dense FP16 of the RTX 5070 for sustained inference throughput.
The L40 offers 362.1 TFLOPS FP16 with sparsity and 48 GB memory that together support fine tuning of models beyond the capacity of the RTX 5070.
The RTX 5070 provides 493.9 TFLOPS FP4 dense performance within a 250 W TDP that suits image generation workloads fitting in 12 GB to 16 GB.
The L40 achieves 90.5 TFLOPS FP32 that doubles the 30.9 TFLOPS FP32 of the RTX 5070 for compute heavy scientific simulations.
Frequently Asked Questions
What is the FP16 dense performance difference between the L40 and RTX 5070?▾
The L40 reaches 181.05 TFLOPS in dense FP16 while the RTX 5070 reaches 61.7 TFLOPS in dense FP16. The ratio favors the L40 by nearly three times for dense tensor operations.
Which GPU has higher memory bandwidth?▾
The L40 provides 864 GB/s of memory bandwidth compared to 672 GB/s on the RTX 5070. Higher bandwidth on the L40 supports increased data throughput in bandwidth limited kernels.
How do the TDP ratings differ between the L40 and RTX 5070?▾
The L40 lists a 300 W TDP while the RTX 5070 lists a 250 W TDP. The lower TDP on the RTX 5070 reduces power requirements in dense deployments.
What FP32 performance does each GPU deliver?▾
The L40 delivers 90.5 TFLOPS in FP32 while the RTX 5070 delivers 30.9 TFLOPS in FP32. The L40 therefore supplies nearly three times the FP32 throughput.
Which interconnect does the RTX 5070 use compared to the L40?▾
