Overview

RTX A4500 is an NVIDIA GPU entry in the NVIDIA RTX A Series family. It is listed with Ampere architecture and GA102 silicon.

Key reference data: 7,168 CUDA cores/shaders, 20 GB GDDR6 memory, 320-bit memory bus, 200 W board power class.

Workstation cards should be checked against driver branch, application certification, memory capacity, and display output requirements.

Why It Mattered

RTX A4500 represents the professional side of NVIDIA RTX A Series and the Ampere generation around 2021. Certified-driver workflows, VRAM configuration, display outputs, and OEM workstation compatibility are the main historical reasons to track it separately from consumer GeForce models.

Collector Notes

For archival use, record the OEM or board-partner part number, bracket height, cooler type, memory configuration, display-output adapter or breakout cable, firmware, certified-driver branch, and the workstation model where the card was used.

Used-Market Caution

Before buying used, confirm bracket height, display adapters, mini-DP or DMS breakout cables, fan condition, VRAM errors, driver branch support, OEM firmware quirks, and whether the card needs workstation-specific airflow or auxiliary power.
