What is the NVIDIA L40?

The L40 is a GPU from NVIDIA on the Ada Lovelace architecture, an accelerator for AI training, inference and high-performance computing. It is a PCIe add-in card, so it fits standard servers and workstations. L40 full specifications →

Can I rent the L40 in the cloud?

Yes. Cloud providers tracked by Flopper rent the L40 by the hour, and the pricing page compares their current rates and the price history side by side. L40 rental prices →

How does the L40 compare with other accelerators?

This page sets the L40 against the RTX 5000 Ada. Both parts launched in the same year. Both are NVIDIA parts, and both ship as a PCIe card, so they fit the same class of system. The compare tool builds the same comparison for any two parts in the catalogue. All GPU comparisons →

Where do the L40 figures come from?

Every L40 figure on this page traces to NVIDIA's own datasheet or specification table. How Flopper verifies specifications →

Figures are dense. Where a vendor publishes a figure it sits under the dense one and never decides a winner. Hover any precision for its definition, or read the GPU glossary.

FLOPS by Precision

What actually differs

Both launched in 2023, the L40 on Ada Lovelace and the RTX 5000 Ada on Ada Lovelace.

The L40 carries 16 GB more memory (48 GB against 32 GB), so larger models fit on one GPU before you shard. Bandwidth is 864 GB/s against 576 GB/s, which sets the ceiling on decode speed.

Power is 300 W against 250 W, and at FP32 the L40 does more work per watt. Weight the FP8 and FP16 rows for LLM work and the FP64 row for HPC.
