Overview

Graphics-First GPU for the Modern Data Center

The NVIDIA L40 is built for organizations that need high-end visual computing in a rack-mountable, enterprise-grade package. Whether you're running virtual workstation sessions for remote design teams, rendering photorealistic product visuals, transcoding live video streams, or running inference on trained models, the L40 handles it in a 300W dual-slot card that fits into the Dell PowerEdge servers you're already running.

With 48GB of GDDR6 memory, third-generation RT Cores for real-time ray tracing, fourth-generation Tensor Cores for AI workloads, and hardware AV1 encode/decode for media pipelines, the L40 consolidates what used to require separate dedicated hardware into a single accelerator. It supports vGPU software for multi-user virtual desktops and connects over PCIe Gen4 for broad server compatibility across Dell PowerEdge 15th and 16th generation platforms.

L40 vs. L40S: Which One Do You Need?

Both GPUs share the Ada Lovelace architecture and 48GB GDDR6 memory. The key differences come down to power budget and workload emphasis.

Use Cases

What the L40 Does Best

Virtual Workstations & VDI

Virtual Workstations & VDI

Give your design, engineering, and creative teams workstation-class performance from anywhere. The L40 with vGPU software delivers GPU-accelerated virtual desktops that rival physical workstations, all managed centrally from your data center. Pair it with a multi-GPU Dell PowerEdge server to support dozens of concurrent users without sacrificing visual fidelity.

3D Rendering & Visualization

3D Rendering & Visualization

Third-generation RT Cores deliver real-time ray tracing for product design, architectural visualization, and content creation workflows. The 48GB of GDDR6 handles complex scenes with high-resolution textures without running out of memory. If your team is using tools like Autodesk, Siemens NX, or Unreal Engine, the L40 accelerates those workloads natively in the data center.

Video & Media Processing

Video & Media Processing

Three hardware encode engines and three decode engines (with AV1 support) make the L40 a strong fit for broadcast streaming, live transcoding, and video production pipelines. Consolidate what used to require dedicated encoding appliances into your existing GPU server infrastructure, reducing rack footprint and operational complexity.

AI Training & Inference

AI Training & Inference

While the L40 isn't positioned as a primary AI training accelerator (that's the H100/H200 territory), it handles single-GPU training, model fine-tuning, and inference workloads effectively. Fourth-generation Tensor Cores support mixed-precision compute, and the 48GB memory capacity accommodates mid-size models comfortably. For teams that need both graphics and light AI in one card, the L40 delivers without requiring a separate accelerator.
