GPU Stress Test
Push your device's graphics processing unit (GPU) and CPU to their limits using intensive HTML5 Canvas rendering. Monitor your FPS to check for thermal throttling or performance drops.
Controls
Warning:Running this test on "High" or "Extreme" settings will cause high CPU/GPU usage, increased fan noise, and rapid battery drain on laptops. It may cause your browser to freeze momentarily on older devices. Use with caution.
Stress Intensity
What is the GPU Stress Test?
The GPU stress test uses intensive HTML5 Canvas rendering to push your computer's Graphics Processing Unit (GPU) and Central Processing Unit (CPU) to their absolute limits right inside your web browser. It renders tens of thousands of overlapping, moving particles with complex blending modes that require massive parallel processing power.
Why Stress Test Your GPU?
Stress testing is crucial for checking system stability. If you've just built a new PC, bought a used laptop, or overclocked your graphics card, you need to ensure the system doesn't crash under heavy load. It's also an excellent way to check for 'thermal throttling'—where your device gets so hot that it automatically slows itself down, causing a sudden drop in FPS.
How to Use This Tool
Select an intensity level based on your hardware (Low for basic laptops, Extreme for dedicated gaming PCs) and click 'Start Stress Test'. Keep an eye on the FPS (Frames Per Second) counter. If your system is stable, the FPS should remain relatively constant. If the FPS suddenly drops by 30-50% after a few minutes, your device is likely overheating and thermal throttling. Note: Extreme settings may cause your browser to temporarily freeze.
