Lenovo Tesla P4 8 GB Passive GPU

The Lenovo Tesla P4 is an 8 GB passive graphics card built on the NVIDIA P4 chipset for server and workstation platforms. It targets compute workloads such as inference, transcoding and virtual desktop infrastructure where a low-profile, fanless design is required. The plug-in card form factor fits standard PCI Express slots in dense chassis.

Passive cooler and plug-in card mounting

A passive cooler means the card relies entirely on chassis airflow, so it must be installed in a system with directed front-to-rear cooling and sufficient static pressure. The plug-in card form factor occupies a single full-height slot and draws power from the PCI Express bus without auxiliary connectors, simplifying cabling in rackmount servers.

PCI Express bus power and passive thermal limits

Because the card draws all power from the slot, total board power is constrained by the PCI Express specification for the connector in use. Sustained compute loads will raise junction temperatures until the chassis airflow reaches equilibrium, so workloads that saturate the GPU for long periods require verified case airflow ratings. The 8 GB frame buffer limits model size and batch depth for inference tasks compared to higher-capacity accelerators.
