GPU detection begins automatically.
The GPU name is a browser-reported hint, not a guaranteed physical model. Browsers may mask the renderer or use an integrated, virtual, or software graphics device. Display color depth is a browser/screen value, not the GPU's internal precision.
LIVE GRAPHICS TEST
3D GPU Benchmark and FPS Test
The test draws a real animated 3D scene using WebGL. Start a preview or run a timed benchmark after the automatic detection above.

There are no invented worldwide rankings, “most seen GPUs” lists, or market-price comparisons. Those require a verified external database; the measurements above are generated locally by your device.
GRAPHICS QUALITY CHECK
Color, Gradient and Rendering Test
Look for smooth gradients, clean color transitions and consistent geometric edges. This is a browser canvas visualization, not a calibrated monitor color test.
Compare the display visually for banding, artifacts and uneven edges.
STEP-BY-STEP GUIDE
How to Test Your GPU Online
You can inspect your GPU in seconds and run a repeatable graphics test whenever you need it.
Read GPU information
Check the renderer name, vendor, WebGL support, screen properties and graphics limits in the first panel.
Select your graphics load
Pick Light, Balanced, High or Intense, then set your preferred resolution scale and test duration.
Run the benchmark
Start the timed test and keep the browser tab visible. FPS and frame-time measurements update while it runs.
Review your results
Read average FPS and 1% low FPS, then copy or export the report for comparison against a matching run.
UNDERSTANDING THE DATA
What Does an Online GPU Test Measure?
Browser-based GPU tools are useful for checking graphics compatibility and real-time rendering behavior, but their results have limits.
GPU renderer and vendor
WebGL can expose a renderer and vendor string. This may include an Apple, Intel, AMD or NVIDIA model, but the information might be masked, virtualized or reported through an intermediate graphics layer. It is not proof of the physical GPU inside your computer.
Frames per second (FPS)
FPS indicates the rate at which frames are delivered in this browser workload. Higher FPS often means smoother animation, but browser frame rates may be capped by the screen's refresh rate. A single FPS value cannot rank all graphics cards fairly.
Frame time and 1% low
Frame time describes how long passes between adjacent animation frames. The 1% low estimate here is calculated from the 99th-percentile frame time of a completed run. It helps show occasional slow frames, not just the average.
WebGL and WebGPU
WebGL renders graphics through the browser. WebGPU is a newer graphics and compute API. Browser support varies, and a WebGPU adapter may be unavailable even when WebGL works.
COMPATIBILITY
GPU Test on Windows, Mac, Android and iPhone
This tool works through the browser instead of installing a dedicated graphics driver utility. On Windows and macOS, use an up-to-date Chrome, Edge, Firefox or Safari browser. On Android and iOS, WebGL availability depends on the device and browser. Start mobile tests with a Light workload.
The page reads available browser graphics properties immediately. It cannot force a laptop to choose its dedicated GPU, and it cannot tell which GPU a game outside the browser is using.
What a browser cannot reliably show
- True GPU temperature and fan speed
- Dedicated video memory (VRAM) capacity
- Clock speed, power draw and GPU utilization
- Guaranteed physical GPU model
- Universal gaming FPS or synthetic benchmark rankings
- Live product prices or global usage statistics without a trusted data source
TROUBLESHOOTING
GPU Test Not Working? Common Fixes
WebGL is unavailable
Update your browser and graphics driver. Check whether hardware acceleration is enabled, and try another browser if a policy or extension blocks WebGL.
The GPU name is missing
Privacy protection or a browser setting may mask the graphics renderer. You can still check the API capabilities and run the benchmark if WebGL works.
FPS is unexpectedly low
Close busy tabs, use a lower preset, connect a laptop to power if appropriate and check whether power-saving mode is limiting performance.
WebGPU says unavailable
WebGPU needs a compatible browser, platform and graphics driver. The WebGL benchmark continues to work independently.
Visual glitches appear
Try another browser, review graphics drivers and compare with other apps. A visual glitch alone does not establish a hardware fault.
The benchmark stops
Switching tabs pauses the test to avoid invalid FPS readings. Keep the page visible and start again; a lost WebGL context may also stop rendering.
FREQUENTLY ASKED QUESTIONS
GPU Test FAQs
Does this GPU test automatically detect my graphics card?
Yes. On page load, JavaScript requests a WebGL context and reads the graphics information the browser exposes. The renderer name may be generic or privacy-masked. No installation or separate connection action is required.
Why does the GPU name show Apple, ANGLE, SwiftShader or a generic renderer?
Browsers may report a graphics translation layer such as ANGLE, an Apple Metal backend, a software renderer like SwiftShader or a masked name. This describes the current browser graphics environment, not necessarily the hardware model printed on the device.
Can I test NVIDIA, AMD, Intel and Apple GPUs?
Yes, as long as the browser exposes a working WebGL context. The same workload can be measured on integrated and discrete GPUs, but compare results only with matching settings and similar browser conditions.
Is this a real GPU performance benchmark?
It renders a real WebGL 3D scene and measures browser animation frame timing. It is a real measurement of this specific workload, not a direct GPU hardware timer or a replacement for native professional benchmarking software.
Does the page measure GPU temperature or VRAM?
No. Websites generally cannot reliably access GPU temperature, fan speed or dedicated VRAM capacity. Max texture size and max renderbuffer size are graphics API limits, not measurements of VRAM.
What is a good FPS result?
It depends on the chosen workload, resolution, screen refresh rate and hardware. A stable frame rate with consistent frame times is often more informative than a single maximum FPS number.
Why can a faster GPU have the same FPS?
The browser may limit rendering to your display's refresh rate, or the workload may be constrained by CPU time, power settings or browser behavior. Equal FPS does not prove equal GPU power.
Does this GPU tester work on mobile devices?
The page layout adapts to phones and tablets, but graphics feature support varies. Start on Light and use a supported up-to-date browser. Some mobile browsers restrict renderer information.
Can this page compare GPU prices and show the most popular graphics cards?
Not accurately from browser data alone. GPU prices and 30-day popularity rankings require verified external datasets and a regularly updated server. This page instead reports your actual browser capabilities and your own benchmark history.
Are my GPU results uploaded?
The detection and rendering calculations on this page run in your browser and the tool does not send test results to a server. The wider website may still use normal hosting, analytics or other services under its privacy policy.
