NVIDIA L40S Graphic Card - 48 GB GDDR6 - PCIe 4.0 x16 - 2x Slot - Ada - 900-2G133-0080-000

The NVIDIA L40S is a 48GB GDDR6 ECC, dual-slot PCIe 4.0 x16 accelerator for data-center AI inference, AI development, and graphics workloads. Its 18,176 CUDA cores and high Tensor Core throughput suit teams running compute-intensive workloads on compatible systems.

Recommended For

• AI teams serving LLMs or image-generation models on a data-center server, when 48 GB of GPU memory fits the model and workload.
• Teams running mixed AI and visual-computing workloads on shared infrastructure, such as inference alongside 3D rendering, graphics, or video processing.
• Data-center and cloud operators providing virtual workstations or GPU-backed applications to multiple users, using supported NVIDIA vGPU software.
• Model-development teams fine-tuning or testing workloads that fit within 48 GB per GPU and can use the L40S’s Tensor Core acceleration in a server deployment.

Real-World Use Scenarios

• A team hosts an open-weight language model for an internal chatbot or API; the L40S can serve inference workloads in a data-center server, with actual response speed and user capacity depending on the model, serving software, and request load.
• An AI developer fine-tunes a smaller language model for a company’s domain or task; NVIDIA provides an L40S-compatible fine-tuning workflow, while the model size and training setup determine how much fits and how long it takes.
• A 3D team renders scenes or serves interactive visualization from a compatible server; the L40S supports GPU-accelerated rendering and virtual workstation workflows, with scene size and application support affecting the experience.
• A media or streaming team processes video for distribution or archiving; the L40S’s dedicated video engines can accelerate supported encoding and decoding workflows, reducing reliance on CPU processing when the software pipeline uses them.
• A developer runs image-generation or other generative-AI inference on a server instead of sending each job to a hosted service; the L40S can accelerate supported models, but output time varies with the model, resolution, and generation settings.
• An organization provisions graphics-rich virtual desktops for designers or engineers; with compatible NVIDIA virtualization software and server hardware, users can work with professional 3D applications remotely rather than relying on local workstation GPUs.
