Before you start
GPU stress tests can significantly increase GPU load, temperature, power draw and fan speed.
Stop the test if your system becomes unstable, overheats, crashes or behaves unexpectedly. Do not run extreme tests on hardware with known cooling problems. This website cannot guarantee hardware safety.
This is a deliberately punishing test. It can push your GPU to its thermal and power limits for minutes.
- Laptops: plug in the charger and make sure the vents are clear.
- Make sure your GPU is cooled properly. Do not run this with known fan or cooling problems.
- Save your work and close other important tabs. A weak or overheated GPU can make the screen flicker or the graphics driver reset, which may close apps.
- You can stop at any time with the Stop button or the Escape key. The test also stops itself if frames take more than two seconds.
Long run: this test keeps the GPU busy for five minutes or more, so your computer will get warm. Laptops should be plugged in. You can stop at any time with the Stop button.

About this test
Allocates, uploads and samples progressively larger textures with mipmaps and anisotropic filtering, up to a safe memory cap. It shows how the GPU and driver behave as video memory fills.
Browsers do not report exact VRAM, and the test stops at a conservative budget, so it is a capacity and bandwidth indicator, not a memory diagnostic. It cannot find faulty memory.
How to read the results
A smooth run means the card kept up as texture memory grew. A sudden drop in frame rate part-way through suggests the working set no longer fits in fast video memory. The Memory Score reflects sampling throughput; compare it between runs on the same machine. See the general guide to verdict axes below the runner for pacing and spikes.
Frequently asked questions
Does this tell me how much VRAM I have?
No. Browsers hide the exact amount. The test only shows where performance changes as memory is used.
Why did the tab reload or crash?
Running out of memory can make the browser drop the graphics context. Lower the intensity and try again.
Is it a RAM test?
No. It tests video memory throughput through the browser. For error checking use a dedicated memory tester.
Why does integrated graphics score lower?
Integrated GPUs share system memory, which is slower than dedicated video memory.
