Overview

A100 SXM4 40 GB is an NVIDIA GPU entry in the NVIDIA A-Series family. It is listed with Ampere architecture and GA100 silicon.

Key reference data: 6,912 CUDA cores/shaders, 40 GB HBM2e memory, 5,120-bit memory bus, 400 W board power class.

Server accelerators should be checked against platform compatibility, cooling, power delivery, firmware, and driver or CUDA support.

Why It Mattered

A100 SXM4 40 GB matters because A100 was part of NVIDIA's Ampere data-center push into AI, HPC, analytics, and multi-instance GPU deployment. Tracking the PCIe, SXM, and memory variants separately helps readers avoid mixing very different server form factors.

Collector Notes

For archival use, record the accelerator form factor, memory capacity, board part number, firmware or VBIOS, cooling type, bracket, interconnect support, power connectors, and the server or workstation it came from.

Used-Market Caution

Before buying used, confirm PCIe versus SXM or OAM form factor, passive airflow needs, auxiliary power, HBM size, firmware locks, ECC or retired-page errors, seller proof from nvidia-smi under load, and whether any vGPU or enterprise licensing is required.
