Performance Analysis
The L40S outperforms in FP16 at 362 TFLOPS compared to the RTX PRO 6000's 125 TFLOPS, making it superior for training large language models where mixed-precision FP16 accelerates convergence without full FP32 accuracy loss of 91 TFLOPS on L40S versus 125 TFLOPS on RTX PRO 6000. Inference workloads benefit from RTX PRO 6000's 2000 TFLOPS FP8 capability, enabling quantized models to process more tokens per second than L40S's 724 TFLOPS FP8.
Memory bandwidth disparity proves critical: RTX PRO 6000's 1792 GB/s supports batch sizes twice as large as L40S's 864 GB/s in VRAM-constrained scenarios like fine-tuning with 96 GB versus 48 GB capacity. Higher TDP on RTX PRO 6000 at 400W versus 350W implies greater cooling demands but sustains peak performance in prolonged runs. NVLink on RTX PRO 6000 enhances multi-GPU scaling over L40S PCIe 4.0 for distributed training.
