Performance Analysis
The L40S outperforms the RTX 5070 dramatically in compute-intensive scenarios due to its superior FP16 rating of 362 TFLOPS versus 40.6 TFLOPS, enabling faster model training where half-precision arithmetic dominates. Its FP32 performance of 91 TFLOPS also exceeds the RTX 5070's 40.6 TFLOPS, benefiting single-precision tasks like scientific simulations. This FP16 to FP32 delta on the L40S, nearly 4 times higher in FP16, accelerates deep learning pipelines by handling larger datasets without precision loss.
Memory bandwidth plays a critical role: the L40S's 864 GB/s supports massive batch sizes in training, reducing iteration times for large language models, while the RTX 5070's 448 GB/s limits it to smaller batches prone to bottlenecks. The L40S's 48 GB VRAM capacity allows loading full models like 70B-parameter LLMs, whereas 12 GB on the RTX 5070 necessitates quantization or offloading, increasing latency. Higher TDP of 350W on the L40S reflects its datacenter design for sustained loads, compared to the RTX 5070's efficient 250W for intermittent use.
FP8 capability on the L40S at 724 TFLOPS further enhances inference speed for quantized models, unavailable or inferior on the consumer RTX 5070.
