Performance Analysis
Superior compute defines the L40's edge: 90.5 TFLOPS FP16 and FP32 versus 29.1 TFLOPS on RTX 4070 Ti translates to roughly three times faster matrix operations critical for AI training and inference. Equal FP16 to FP32 ratios on both GPUs ensure balanced performance across precision levels, avoiding bottlenecks in mixed workloads.
Memory specs amplify this gap. L40's 48 GB VRAM and 864 GB/s bandwidth support larger batch sizes in model training, such as fitting billion-parameter LLMs without swapping, compared to RTX 4070 Ti's 12 GB limit. Higher bandwidth reduces data starvation in inference pipelines, enabling 1.7 times quicker throughput for memory-bound tasks like Stable Diffusion generation.
