01
How to use this test
- Close games or graphics-heavy apps for a cleaner result.
- Select Run GPU benchmark and keep the tab visible.
- Review graphics throughput, API support and the renderer reported by your browser.
02
If something looks wrong
- Plug laptops into power when testing maximum graphics performance.
- Update your browser and graphics driver if WebGL is unavailable.
- Use the same browser and display setup when comparing scores.
What the result means
A timed WebGL loop checks browser graphics throughput and capabilities.
The benchmark creates a 512 × 512 off-screen graphics context, prefers WebGL 2 and falls back to WebGL 1. It compiles a small shader, submits repeated full-canvas draws for about 1.25 seconds and synchronizes the work before calculating draws per second and a Test My Everything score.
This deliberately narrow task verifies that accelerated browser graphics work and offers a repeatable local comparison. The result depends on the GPU, driver, browser, power selection, thermal state and the cost of synchronizing commands. It is not an estimate of frame rate in a particular game.
Reading the signal
Read throughput together with the graphics capability report.
WebGL version
WebGL 2 exposes newer browser graphics features; a WebGL 1 fallback can reflect hardware, driver or browser policy.
Draws per second
This is the completed throughput of the page's simple synchronized shader workload, not triangles or frames in a game.
Browser GPU score
The displayed score is rounded draws per second divided by 25 and only belongs to this benchmark version.
Renderer information
Some browsers expose a generalized renderer to reduce fingerprinting, so a vague name does not prove software rendering.
Browser-test limits
The test does not measure VRAM capacity or bandwidth, ray tracing, video encoding, gaming FPS, temperature, power or stability under a long load. Scores from unrelated GPU benchmarks use different workloads and are not interchangeable.

From symptom to next step.
What you seeLikely causeWhat to try
WebGL is unavailableHardware acceleration is disabled, the driver is blocked or the browser and remote session do not expose a context.Check browser acceleration settings, update through the device vendor or operating system and restart before testing outside remote desktop.
Score is unexpectedly lowThe browser may use an integrated GPU, battery-saving mode or a busy graphics process.Connect power, close graphics-heavy tabs, review per-app GPU settings and compare three runs in the same browser.
Renderer name is genericThe browser is limiting identifying graphics information for privacy.Use the operating system or vendor control panel if an exact adapter model is required; do not infer failure from a generic label.
Quick answers
Good to know.
Does this test use my graphics card?+
Yes. The rendering workload is submitted through WebGL to the graphics system selected by your browser and operating system.
Why is my GPU name hidden?+
Some browsers and privacy settings deliberately mask detailed renderer information. The benchmark can still run without revealing the model.
Can this show GPU temperature or VRAM?+
No. Web pages do not receive reliable access to graphics temperature, utilization or dedicated video-memory totals.
Is this a gaming benchmark?+
No. It is a short browser graphics workload and cannot predict the settings or frame rate of a specific game.
What does WebGPU unavailable mean?+
The newer WebGPU API is not exposed in this browser and setup. WebGL can still work normally, and the absence alone does not indicate a defective GPU.
Why does a laptop score change on battery?+
Many laptops lower GPU clocks or select an integrated adapter to save energy. The browser follows those system and driver policies.
