The NVIDIA L40 is an Ada Lovelace data center GPU that combines graphics, rendering and AI in one card. It is often used for virtual workstations, NVIDIA Omniverse and AI inference. It has 18,176 CUDA cores and 48 GB of GDDR6 memory with ECC, with 864 GB/s of bandwidth.
The card connects over PCIe 4.0 x16, has a maximum power of 300 W and provides four DisplayPort 1.4a outputs. It is a dual-slot, passively cooled design measuring 4.4 in by 10.5 in, intended for server installation with directed airflow. Compared with the L40S, which uses the same memory size, the L40 has a lower power limit. Confirm your server supports it before ordering.
