Two Ways to Test Your GPU
When you want to stress test your GPU, you have two main options: browser based tests that run in your web browser, or desktop software that you download and install.
Both approaches push your GPU under load. But they do it differently and each has clear strengths.
Browser Based Tests
Browser tests use WebGL or WebGPU to render graphics directly through your browser. You do not need to install anything.
Advantages
No downloads required. Works on any operating system. Safe and sandboxed by the browser. Instant results. Tests real web graphics performance. Works on phones and tablets too.
Limitations
Cannot read GPU temperature or power draw. Browser overhead adds a small performance cost. Limited to WebGL and WebGPU APIs. Cannot test DirectX or Vulkan rendering.
Desktop Software Tests
Desktop tools like FurMark, 3DMark, and Unigine run natively on your system with full hardware access.
Advantages
Full hardware access including temperature sensors. More intensive workloads. DirectX, Vulkan, and OpenGL support. Overclocking integration. Industry standard benchmarks for comparison.
Limitations
Requires download and installation. Usually Windows only. Some tools are paid. Can cause overheating if used carelessly. Takes more time to set up.
When to Use Which
- Quick GPU health check: use browser tests
- Testing a new or used GPU purchase: start with browser tests, then use desktop tools
- Validating an overclock: use desktop tools with temperature monitoring
- Comparing devices (phone vs laptop vs PC): use browser tests
- Testing web app GPU performance: use browser tests
- Thermal stress testing: use desktop tools
- Getting a benchmark score to compare with others: use 3DMark
Our Recommendation
Use both. Start with our free browser tests for a quick check. If you need deeper analysis, download desktop software from our software page.
Browser tests are perfect for day to day quick checks. Desktop tools are for when you need the full picture including temperatures and power draw.
