NVIDIA L40S

48 GB decides what fits. 864 GB/s decides how fast it runs once it does.

Open in the calculator →Best models for 48 GB, on every card that size →

Quick answer
The NVIDIA L40S fits 226 of 320 sized models entirely in its 48 GB; the largest widely used one is Kimi-Linear-48B-A3B-Instruct (30.4 GB at Q4_K_M). Memory decides what fits; its 864 GB/s of bandwidth decides how fast it answers.

At 8,192 tokens of context with the whole model in device memory. Speeds are estimates from memory bandwidth, not benchmarks run on this card.

226 of 320 fit entirely

226 of the 320 models the engine can size fit entirely in device memory at Q4_K_M where it is published, otherwise the nearest published format, and 8,192 tokens. 18 run with some layers on system memory (32 GB assumed), and 76 do not run at all.

These examples are selected from prominent labs using the catalogue’s latest Hugging Face 30-day downloads and repository-creation freshness signal, with newer releases guaranteed a place. Offloaded rows assume 32 GB of system RAM, and a speed is only shown for a row that runs. Fitting in memory is not the same as loading: whether the runtime and version you have supports each architecture and format on this machine has not been tested here. Each “Open” link carries the same model, format, context and RAM into the calculator.

Every model that fitswhole model resident · offload off

The most demanding model that fits is Qwen2.5-VL-72B-Instruct at Q4_K_M: 47.3 GB of the 48 GB, leaving 0.70 GB spare.

Fully resident at 8,192 tokens (or the model’s own maximum, where that is shorter), offload off, at 864 GB/s. Each row is a run of the engine for this configuration; the rows start with current, prominent releases and “fits” is memory, not a tested runtime. Older or less prominent models remain available through this search and “Show all”.

Buy one or rent one?

Your price, your hours, your electricity. Everything else is arithmetic.

4 h

Watts start at the NVIDIA L40S’s published board power (350 W), an upper bound: decoding rarely holds a card at its limit. Rent starts at the cheapest live price (Vast.ai). The electricity price is a placeholder — put yours in.

At 4 h a day, renting costs $1,007.40 a year.

  • That is $83.95 a month, and nothing when the machine is stopped.
  • Owning would cost $127.75 a year in electricity, on top of the price.
  • Every $1,000 of purchase price takes 1.1 years of this use to earn back.

Enter the price you would pay to see the exact break-even.

On-demand prices for the whole machine. Vast hosts below 98% measured reliability are left out; RunPod’s Community Cloud is vetted third-party hosts and its Secure Cloud is data-centre capacity. Every rentable card compared.

Referral links Vast.ai, RunPod and Novita pay us a share of what you spend if you sign up through these buttons. It costs you nothing, and it never decides an order or a recommendation: both are computed from the live price and the speed, and options that pay us nothing are listed and recommended on the same terms.

Caveats

  • The page's Tensor Core throughput figures are footnoted "With Sparsity" and are not used.
  • A passively cooled data-center card: the power figure assumes server airflow.
  • No dense matrix throughput is published for this device in a form this catalogue accepts, so no compute roof is priced and time to first token is withheld.

Published capacity is a hardware ceiling, not guaranteed free runtime memory. The calculator shows the runtime reserve separately rather than folding it into a single number.
