Online GPU Benchmark — Test Your Graphics Card

A free browser-based GPU benchmark that measures your graphics card performance using WebGL. Tests particle rendering, 3D geometry, and shader processing to produce a score from 0 to 10,000. No downloads required — runs entirely in your browser.

How to Benchmark Your GPU Online

Open the tool

No installation needed. Works in any browser with WebGL 2.0 support (Chrome, Firefox, Edge, Safari).

Click Run Benchmark

The test runs for about 30 seconds, progressively increasing difficulty with particles, geometry, and shaders.

Frequently Asked Questions

How does the GPU benchmark work?

The tool uses WebGL to render increasingly complex scenes — starting with 10,000 particles, scaling to 100,000, then adding rotating 3D geometry with Phong lighting, and finishing with heavy shader computations. FPS is measured at each stage to calculate a final score.

What is a good GPU benchmark score?

Scores above 7,000 indicate excellent GPU performance in the browser. 4,000–7,000 is above average. 2,000–4,000 is typical for integrated graphics. Below 2,000 suggests limited GPU capability.

Is the stress test safe for my GPU?

Yes. The stress test runs within the browser sandbox and cannot overheat or damage your GPU. It automatically stops if FPS drops below 5 for 3 seconds. Your GPU drivers and OS thermal management remain in full control.

Why does it show "WebGL not supported"?

Your browser may have WebGL disabled, or your GPU drivers may be outdated. Try updating your graphics drivers, enabling hardware acceleration in browser settings, or switching to Chrome or Firefox.

Can I compare scores between devices?

Yes, the scoring is consistent across devices. However, browser and OS differences can affect results by 5–10%. For the most reliable comparison, use the same browser on both devices.
