L40S vs RTX 5070

The FP16 dense figure of 362.05 TFLOPS on the L40S exceeds the 61.7 TFLOPS dense figure on the RTX 5070 by a factor derived directly from those values. This gap implies that training and inference steps complete more operations per second on the L40S when both GPUs run dense FP16 workloads. The FP32 value of 91.6 TFLOPS on the L40S compared to 30.9 TFLOPS on the RTX 5070 further widens the advantage for precision sensitive phases. Memory bandwidth of 864 GB per s versus 672 GB per s allows the L40S to sustain larger batch sizes before memory becomes the limiting factor. Sparse FP16 performance follows the same pattern with 733 TFLOPS on the L40S against 123.5 TFLOPS on the RTX 5070.

The L40S suits workloads that require the full 48 GB VRAM capacity and the 362.05 TFLOPS dense FP16 rating. Scientific computing tasks benefit from the 91.6 TFLOPS FP32 performance paired with 864 GB per s bandwidth. Higher TDP of 350 W is acceptable when maximum throughput per GPU takes priority over power draw.

The RTX 5070 fits scenarios where 250 W TDP reduces overall system power consumption. Its PCIe 5.0 interconnect supports newer host platforms while the 672 GB per s bandwidth remains adequate for lighter inference loads that fit within 12 to 16 GB VRAM.
