GPU Benchmark
One unified suite covering 3D rendering, shader performance, VRAM & texture, particle systems, and volume shader raymarching — run them individually or all at once for an overall GPU score.
GPU Benchmark
Five GPU stress tests in one suite: 3D rendering, shader performance, VRAM & texture, particle system, and volume shader raymarching. Run any test on its own, or run the whole suite for an overall score.

About this tool
One unified GPU benchmark combining all five stress tests from the GPU Testing suite: animated 3D mesh rendering, a custom GLSL fbm-noise fragment shader, an escalating texture-size and filtering test, a CPU-physics-driven particle system, and a raymarched Mandelbulb fractal shader. Switch between modules with the tab selector, run any test on its own, or click "Run complete benchmark" to sequence through all five automatically and get a single overall GPU score.
Each module keeps its original measurement logic untouched — FPS, frame time, stability, and module-specific metrics like draw calls, VRAM estimate, physics updates/second, or pixels/second are all computed exactly as in the standalone tools. Only one WebGL context is ever active at a time: switching modules or advancing through the full suite tears down the previous module's renderer before the next one starts, and the render loop stops scheduling frames whenever the browser tab is hidden.
Key features
- Five GPU stress tests in one page: 3D rendering, shader performance, VRAM & texture, particle system, and volume shader raymarching
- "Run complete benchmark" auto-sequences all five modules and reports an aggregated overall score
- Individual Start/Stop per module, plus a Reset control to clear the unified report
- Unified report: overall score, average/min/max FPS across all runs, total duration, per-module score bars, and an overall rating
- Only one WebGL renderer active at a time — modules tear down cleanly on switch to avoid context leaks
Why use it
- Get one overall GPU score instead of running five separate pages
- Compare relative strengths across rendering, shading, texture bandwidth, and physics-heavy workloads in one report
- Faster before/after comparisons after a driver update or hardware change
Why gpu testing testing matters
A GPU that runs cool and stable in a game menu can still throttle, artifact, or crash under sustained load. Browser-based stress tests are a fast first check: if a tab-based WebGL workload already causes stutter, driver crashes, or visual corruption, that's a strong signal worth following up with a full diagnostic tool before you trust the card under heavier load.
Tips for accurate results
- Close other GPU-heavy tabs and applications before running a test — background compositing can skew results.
- Watch for visual artifacts (flickering polygons, texture corruption, screen tearing) as much as the raw frame rate — they often show up before a full crash.
- Run the same test twice in a row; a big drop on the second run can indicate thermal throttling.
- If a laptop, make sure it's on a hard, ventilated surface and not defaulting to the integrated GPU.
Frequently asked questions
Is this as accurate as 3DMark or FurMark?
No. Browser WebGL benchmarks are useful for quick relative comparisons and stability checks, but native benchmarking tools access the GPU more directly and are more rigorous for serious performance analysis.
My score seems low for my GPU tier.
Browser tabs are subject to OS-level throttling, background processes, and driver overhead that native apps avoid. Compare against a baseline run on the same machine rather than published scores from other hardware.
Why does the "Run complete benchmark" switch tabs on its own?
Each module needs to be visible and mounted to its own canvas to render, so the suite automatically switches to whichever module is currently running and tears down the previous one's WebGL context first.
