Performance Analysis

The L40S demonstrates superior compute throughput with 362 TFLOPS FP16 versus 10.1 TFLOPS on the RTX 2080 Ti, enabling training of large neural networks up to 36 times faster in mixed precision. Its FP32 performance of 91 TFLOPS outpaces the RTX 2080 Ti's 10.1 TFLOPS by a factor of nine, benefiting scientific simulations requiring single-precision accuracy. FP8 capability at 724 TFLOPS on the L40S further accelerates inference for quantized models.

Memory specifications profoundly impact real-world usage. The 48 GB VRAM on the L40S supports batch sizes for billion-parameter LLMs that exceed the RTX 2080 Ti's 11 GB limit, reducing per-iteration overhead. Higher bandwidth of 864 GB/s compared to 616 GB/s minimizes data transfer bottlenecks during inference, allowing sustained high throughput. The L40S TDP of 350W reflects its power for intensive tasks, versus 215W on the RTX 2080 Ti for lighter loads.

Interconnect differences matter in multi-GPU setups: PCIe 4.0 on the L40S versus NVLink on the RTX 2080 Ti influences scaling efficiency.
