About this test
The GPU test shows the graphics card and driver the browser is using, which reveals whether a laptop is running on integrated or dedicated graphics. The benchmark renders a fractal shader at rising complexity and records the highest sustained throughput as a score. It is useful for checking hardware acceleration and spotting overheating.
How to use this test
- Check the GPU name in the details table.
- Press Run GPU benchmark and keep the tab visible.
- Compare scores before and after driver updates or on different power modes.
Frequently asked questions
The GPU shown is my integrated graphics. Why?
Your system assigns the browser to the power-saving GPU. Choose high performance for the browser in graphics settings.
WebGL is disabled. How do I enable it?
Turn on “Use hardware acceleration” in your browser settings and update your graphics driver.
Is my score uploaded?
Only if “Add my score anonymously to the public rankings” is ticked. Then the scores and basic device details (graphics chip, system, browser, thread count and memory) are sent without cookies or your IP address. Untick it before running the test to keep the result on your device only.
