NVIDIA L40S
Unparalleled AI and Graphics Performance for the Data Center
The NVIDIA L40S GPU, based on the Ada Lovelace architecture, is the most powerful universal GPU for the data center, delivering breakthrough multi-workload acceleration for large language model (LLM) inference and training, graphics, and video applications. As the premier platform for multi-modal generative AI, the L40S GPU provides end-to-end acceleration for inference, training, graphics, and video workflows to power the next generation of AI-enabled audio, speech, 2D, video, and 3D applications.
Powered by the NVIDIA Ada Lovelace Architecture
Hardware support for structural sparsity and optimized TF32 format provides out-of-the-box performance gains for faster AI and data science model training. Accelerate AI-enhanced graphics capabilities with DLSS to upscale resolution with better performance in select applications
Third-Generation RT Cores
Enhanced throughput and concurrent ray-tracing and shading capabilities improve ray-tracing performance, accelerating renders for product design and architecture, engineering, and construction workflows. See lifelike designs in action with hardware-accelerated motion blur and stunning real-time animations.
Transformer Engine
Transformer Engine dramatically accelerates AI performance and improves memory utilization for both training and inference. Harnessing the power of the Ada Lovelace fourth-generation Tensor Cores, Transformer Engine intelligently scans the layers of transformer architecture neural networks and automatically recasts between FP8 and FP16 precisions to deliver faster AI performance and accelerate training and inference.
Data Center Ready
The L40S GPU is optimized for 24/7 enterprise data center operations and designed, built, tested, and supported by NVIDIA to ensure maximum performance, durability, and uptime. The L40S GPU meets the latest data center standards, is Network Equipment-Building System (NEBS) Level 3 ready, and features secure boot with root of trust technology, providing an additional layer of security for data centers.

| Question | What is the NVIDIA L40S and who is it for? |
| Answer | The NVIDIA L40S is a data-center GPU based on the NVIDIA Ada Lovelace architecture. It is designed for demanding AI and generative AI workloads, LLM training and inference, 3D rendering, visualization, simulation, and professional graphics applications. |
| Question | What are the key specifications and features of the NVIDIA L40S? |
| Answer | The NVIDIA L40S features 48GB GDDR6 ECC memory, 18,176 CUDA cores, 568 fourth-generation Tensor Cores, 142 third-generation RT Cores, 864GB/s memory bandwidth, and PCIe Gen4 x16. It has a 350W maximum power consumption, passive cooling, and a dual-slot form factor. |
| Question | How does the NVIDIA L40S perform for AI and generative AI workloads? |
| Answer | The L40S is built for AI training and inference and supports NVIDIA's Transformer Engine for FP8 and FP16 workloads. NVIDIA specifies up to 1,466 TFLOPS FP8 Tensor performance with sparsity, making it suitable for demanding generative AI and LLM workloads. |
| Question | How much memory does the NVIDIA L40S have, and can I upgrade it? |
| Answer | The NVIDIA L40S has 48GB of GDDR6 memory with ECC and 864GB/s memory bandwidth. The GPU's onboard memory is a fixed hardware specification rather than a user-upgradable RAM or storage option. |
| Question | What ports and connectivity does the NVIDIA L40S offer? |
| Answer | The NVIDIA L40S uses a PCIe Gen4 x16 interface with 64GB/s bidirectional bandwidth and provides four DisplayPort 1.4a outputs. It also uses a 16-pin power connector and has three NVENC and three NVDEC engines, including AV1 encode and decode support. |
| Question | Is the NVIDIA L40S suitable for professional and enterprise use? |
| Answer | Yes. The L40S is designed for enterprise data-center operation and supports AI, data science, professional visualization, rendering, and virtualized workstation workloads. NVIDIA also lists NVIDIA vGPU software support, making it suitable for shared virtual GPU environments. |
| Question | Is the NVIDIA L40S a good choice for businesses in Dubai and the UAE? |
| Answer | The NVIDIA L40S can be a strong option for UAE businesses running AI services, generative AI, data science, 3D visualization, rendering, and virtual workstations. For deployment in a Dubai data center or server room, buyers should also verify server compatibility, PCIe Gen4 x16 support, power delivery, and appropriate passive-GPU airflow. |
| Question | NVIDIA L40S vs NVIDIA L40: which GPU is better for AI workloads? |
| Answer | Both GPUs use the Ada Lovelace architecture and have 48GB GDDR6 ECC memory, but the L40S is the higher-performance option for many AI workloads. NVIDIA lists the L40S at 91.6 FP32 TFLOPS and up to 1,466 FP8 TFLOPS with sparsity, compared with the L40's lower published compute figures. The L40S also has a higher maximum power consumption of 350W versus 300W for the L40. |
| Question | What should I consider before choosing an NVIDIA L40S? |
| Answer | Check that your server supports a dual-slot, passively cooled PCIe Gen4 x16 GPU, provides the required 16-pin power connection and adequate airflow for its 350W maximum power consumption. Also consider whether you need 48GB GPU memory, vGPU capabilities, AI acceleration, professional rendering, or video processing. NVIDIA states that L40S does not support MIG or NVLink, which may also matter for specific deployments |
| Question | Why choose Promise Store for NVIDIA L40S? |
| Answer | Promise Store serves UAE customers with professional NVIDIA GPU solutions and provides expert product guidance, warranty support, and business-focused assistance. Promise Store also lists a physical Dubai location and UAE contact options, which can be useful when planning an enterprise GPU deployment. |
