Performance Analysis
The FP16 dense figure of 181.05 TFLOPS on the L40 exceeds the 112.6 TFLOPS dense figure on the RTX 5080 by a factor of 1.6. This difference affects training throughput where higher dense FP16 capacity supports larger model updates per step. FP32 performance follows a similar pattern at 90.5 TFLOPS dense for the L40 versus 56.3 TFLOPS dense for the RTX 5080. Memory bandwidth of 960 GB/s on the RTX 5080 exceeds the 864 GB/s on the L40 and permits modestly larger batch sizes during inference when data movement limits throughput. Sparse FP16 performance reaches 362.1 TFLOPS on the L40 and 225.1 TFLOPS on the RTX 5080 so the ratio remains consistent when sparsity applies to both devices.

When to Choose the L40
The L40 suits workloads that require the 48 GB VRAM capacity for fitting models that exceed 16 GB limits. Its 181.05 TFLOPS dense FP16 rating and 300W TDP also favor sustained dense compute tasks where power draw stays lower than the 360W of the RTX 5080.
When to Choose the RTX 5080
Its FP4 dense rating of 900.4 TFLOPS further supports low precision inference pipelines unavailable on the L40.
Use Cases
The L40 supplies 48 GB VRAM and 181.05 TFLOPS dense FP16 that together exceed the 16 GB and 112.6 TFLOPS dense FP16 of the RTX 5080.
The RTX 5080 delivers 960 GB/s bandwidth and FP4 dense performance of 900.4 TFLOPS that improve token throughput over the L40 specifications.
The L40 48 GB VRAM capacity permits fine-tuning runs that the 16 GB VRAM of the RTX 5080 cannot accommodate at equivalent model sizes.
Both GPUs handle image generation yet the L40 offers more VRAM while the RTX 5080 provides higher bandwidth.
The L40 FP32 rating of 90.5 TFLOPS dense surpasses the 56.3 TFLOPS dense rating of the RTX 5080 for double precision workloads.
