Performance Analysis

The L40S outperforms the RTX 4070 Ti significantly in compute-intensive tasks due to its superior FP16 performance of 362 TFLOPS versus 29.1 TFLOPS: this enables faster AI model training and inference where half-precision arithmetic dominates. Its FP32 rating of 91 TFLOPS also exceeds the RTX 4070 Ti's 29.1 TFLOPS, supporting more general-purpose computing. The FP16 to FP32 ratio on L40S favors mixed-precision workflows common in deep learning, while the RTX 4070 Ti's balanced metrics suit graphics rendering.

Memory bandwidth of 864 GB/s on the L40S versus 504 GB/s on the RTX 4070 Ti directly impacts batch sizes: larger batches fit in training loops without swapping to host memory, reducing latency in LLM fine-tuning. The L40S's 48 GB VRAM handles models exceeding 12 GB on the RTX 4070 Ti, preventing out-of-memory errors in high-resolution Stable Diffusion or scientific simulations. Power draw differs at 350W for L40S and 200W for RTX 4070 Ti, influencing cloud instance costs for prolonged runs.
