About Stress My GPU

Stress My GPU is a free, browser-based tool for people who want to know whether their graphics hardware is healthy, how it behaves under sustained load, and how it compares with their expectations. It exists because most online GPU tests give you a number and nothing else.

What we do differently

• Judgement, not just a number. The SMG Verdict profiles power, steadiness, endurance, pacing and spike control, then explains in plain language what to do next.
• Honest about limits. We tell you when a result is capped by your monitor, when a GPU name is masked, and when a run was too short to be confident.
• Private by design. All workloads run on your device. Results stay in your browser unless you explicitly choose to share an anonymous aggregate.
• Safe by design. Memory, particle and shader limits are capped, tests can be stopped at any time, and there is a warning before heavy loads.

Privacy

We do not use accounts or advertising cookies. If anonymous results are enabled on this site and you consent, only aggregate metrics (test, API, intensity, resolution, duration, FPS statistics, score and the browser-reported GPU name) are stored. IP addresses, cookies and user agents are not stored with results.

Safety

GPU stress tests increase load, temperature, power draw and fan speed. Stop if your system becomes unstable. Do not run Extreme tests on hardware with known cooling problems. Stress My GPU cannot guarantee hardware safety.
