NVIDIA L40 48GB PCIe
The NVIDIA L40 48GB PCIe is a data-center GPU built on the NVIDIA Ada Lovelace architecture, with 48 GB GDDR6 with ECC memory and 864GB/s of memory bandwidth. It has a board power of 300 W in a 4.4″ (H) x 10.5″ (L) Dual Slot form factor.
Overview
The NVIDIA L40 48GB PCIe is a data-center GPU built on the NVIDIA Ada Lovelace architecture for AI inference, graphics and virtualized workloads. It combines 48 GB of GDDR6 with ECC and 864 GB/s of memory bandwidth in a 300 W, 4.4” × 10.5” dual-slot, passively cooled PCIe card — the passive design lets it sit in a server airflow path rather than needing its own fans.
At a glance
- Architecture: NVIDIA Ada Lovelace; 48 GB GDDR6 with ECC at 864 GB/s
- Board power: 300 W; bus: PCIe Gen4 x16; 16-pin power connector
- Form factor: 4.4” (H) × 10.5” (L), dual slot; passive cooling
- Display: 4x DisplayPort 1.4a
- Media: 3x NVENC and 3x NVDEC (including AV1 encode and decode)
- vGPU software: vPC/vApps, RTX Virtual Workstation (vWS)
- Secure Boot with Root of Trust; NEBS Level 3 ready
When to choose the L40
The L40 is for servers that need a passive, rack-optimised card for inference, virtual desktop and graphics, with 48 GB of ECC memory and a strong media engine (3x NVENC / 3x NVDEC including AV1). Its passive cooling and NEBS Level 3 readiness suit dense and telco/edge deployments. It does not support Multi-Instance GPU, so for partitioning look at the H100/H200 class.
Platform & compatibility
The L40 installs in a PCIe Gen4 x16 slot with a 300 W budget, a 16-pin power connector and adequate server airflow for its passive heatsink, and provides four DisplayPort 1.4a outputs. It is supported by NVIDIA vGPU software and is NEBS Level 3 ready.
FAQ
How much memory does it have? 48 GB of GDDR6 with ECC.
Is it actively or passively cooled? Passively — it relies on server airflow.
