NVIDIA L40S 48GB

NVIDIA L40S 48GB graphics card — accelerator for AI and visualisation

NVIDIA L40S 48GB graphics card — a server accelerator based on the Ada Lovelace architecture, designed specifically for generative AI tasks, large language model (LLM) inference, and professional visualisation. This card combines high computing power and versatility, allowing it to be used for both neural network training and inference, as well as for graphics applications or video processing.

Key features

• Architecture: Ada Lovelace
• CUDA cores: 18,176
• Tensor Cores (4th generation): 568
• RT cores (3rd generation): 142
• Memory: 48 GB GDDR6 ECC
• Memory bandwidth: 864 GB/s
• Interface: PCIe Gen4 x16
• Power consumption: up to 350 W
• Codecs: 3× NVENC and 3× NVDEC (AV1 support)
• Video outputs: 4× DisplayPort 1.4a
• vGPU support: NVIDIA AI Enterprise, RTX Virtual Workstation
• Cooling: passive, requires a server with airflow

What does NVIDIA L40S performance offer in practice?

• Lag-free LLM operation. The card allows large language models (e.g., GPT-class) to be served faster and more stably, which is important for chatbots, analytics, and recommendation systems.
• Generative AI. With twice the tensor power of the L40, the L40S is ideal for working with images, videos, and text, where billions of parameters are involved.
• Graphics and video processing. Support for three NVENC/NVDEC with AV1 accelerates high-quality video streaming, encoding, and playback.
• Balance between server and visual tasks. Unlike the H100, which is designed almost exclusively for AI, the L40S can handle both visualisation and generative tasks equally well.
• Resource savings. With power consumption of up to 350 watts, the L40S delivers high performance per watt, making it a cost-effective choice for data centres and integrators. 

What’s special about the NVIDIA L40S graphics card?

1. Versatility: the card is equally effective at AI and graphics tasks, unlike the H100/H200, which are designed exclusively for AI.
2. Higher performance compared to NVIDIA L40 — twice the tensor power (FP8 and FP16), which is critical for generative AI and LLM inference.
3. Server reliability: ECC memory and passive cooling for round-the-clock operation.
4. vGPU support allows resources to be shared between multiple virtual machines — beneficial for data centres and cloud solutions.
5. AV1 codecs make the card suitable for video processing, streaming and visualisation tasks. 

Comparison with other models

• L40S vs L40: the basic L40 consumes less power (300 W), but the L40S is almost twice as powerful in tensor operations, making it preferable for generative AI.
• L40S vs RTX 6000 Ada 48GB: both cards use Ada Lovelace architecture and 48 GB of memory, but the RTX 6000 is a ‘workstation’ for designers and 3D visualisation, while the L40S is a server solution for AI and data centres.
• L40S vs H100 80GB: The H100 remains the absolute leader in AI performance, but it comes at a higher price. The L40S is more cost-effective when a balance between performance and cost is required.

What is NVIDIA L40S 48GB suitable for?

• Generative AI (text, images, video);
• Inference and training of medium and large LLM models;
• Workstation virtualisation with RTX vWS;
• engineering graphics and rendering;
• broadcasting and video processing in AV1.
