Introduction
One of the most important tasks you can do to your GPU is to test its performance so that you know what it can do and if it is running as it should. In this guide, we explain the entire process of performing an automated test, from simple preparations to analysis of the resultant findings, with current tools and methodologies as of 2025.
Preparation for GPU Testing
System Preparation
Prepare your system before starting any GPU tests:
Clean Installation
