How to use this test
The GPU test shows the graphics processor your browser is using, whether WebGL 2 and WebGPU are available, and runs a short WebGL benchmark that gets heavier in three steps. It reports the frame rate in each step and combines them into a score you can compare between browsers, power settings and computers.
Read the GPU details first. Close other heavy tabs and plug in your laptop, then press Run benchmark and wait about 15 seconds. For a longer check, run the 60 second stress test and watch whether the frame rate falls as the GPU warms up.
What the results mean
A higher score is better; the heavier steps count more toward it. If every step runs at your screen's refresh rate, the display is the limit, not the GPU, and the result says so. A laptop showing its integrated graphics when you expected the gaming GPU is running the browser on the power-saving chip, which you can change in the graphics settings. A falling line in the stress test points to heat or power limits.
Common questions
Why does it show a generic name or the wrong graphics card?
Browsers report the GPU differently. Chrome and Edge show the real model, Firefox shows a similar stand-in model to protect your privacy, and Safari always says Apple GPU. Laptops also run the browser on the integrated GPU to save power; in Windows, Settings, then System, Display, Graphics lets you choose the high-performance GPU for your browser.
Is this the same as a game benchmark?
No. It measures what your GPU can do through the browser, which adds overhead. Use it to compare runs on the same kind of setup, not to rank your card against desktop benchmark charts.
Is the stress test safe?
Yes. It's a minute of ordinary graphics work, much like playing a game. Louder fans are expected, and you can stop at any time.
