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 L40S. 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 →

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 L40S on Ada Lovelace.

Both carry 48 GB of memory. Bandwidth is 864 GB/s against 864 GB/s, which sets the ceiling on decode speed.

Power is 300 W against 350 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.

Frequently asked questions

Is the L40 faster than the L40S?

At FP8 precision the L40S reaches 733 TFLOPS dense against 362 TFLOPS for the L40. The performance table on this page lists every published precision for both GPUs.

Which should you choose, the L40 or the L40S?

Choose the L40S for training and high-throughput inference: it has 2.0x the FP8 throughput of the L40. The L40S draws 50 W more power, so budget for cooling and power delivery before you commit.

Which has more memory, the L40 or the L40S?

Both GPUs carry 48 GB of memory. Memory bandwidth is 864 GB/s for the L40 and 864 GB/s for the L40S.

How much power do the L40 and the L40S draw?

The L40 is rated at 300 W TDP and the L40S at 350 W. On FP32 throughput per watt, the L40 is the more efficient part.

How much do the L40 and the L40S cost to rent?

Live cloud listings tracked by Flopper price the L40 from $0.46 per GPU-hour across 8 providers, and the L40S from $0.38 per GPU-hour across 24 providers. The rental section on this page links to every provider, rate and the price history for each GPU.
