L40 vs Quadro RTX 4000

The FP16 dense rating of 181.05 TFLOPS on the L40 exceeds the 57 TFLOPS dense FP16 rating on the Quadro RTX 4000 by a factor of three. This gap allows the L40 to process larger models during inference and training steps that rely on dense FP16 operations. The FP32 rating of 90.5 TFLOPS on the L40 compared with 7.1 TFLOPS on the Quadro RTX 4000 indicates a twelvefold advantage in single precision workloads. Memory bandwidth of 864 GB/s on the L40 versus 416 GB/s on the Quadro RTX 4000 supports larger batch sizes before memory limits are reached. FP16 with sparsity on the L40 reaches 362.1 TFLOPS while the Quadro RTX 4000 provides no sparsity figure for comparison.

The L40 serves workloads that require 48 GB of VRAM and 181.05 TFLOPS dense FP16 performance. Scientific computing tasks benefit from the 90.5 TFLOPS FP32 rating and 864 GB/s bandwidth when handling large datasets. Fine tuning operations scale with the 362 TFLOPS dense FP8 rating that the Quadro RTX 4000 does not match.

The Quadro RTX 4000 fits environments limited to 125W TDP and 8 GB VRAM. Basic inference jobs that stay under 57 TFLOPS dense FP16 remain viable on this card. Older PCIe 3.0 systems accept the Quadro RTX 4000 without requiring newer interconnect support.
