GPU Benchmark

GPU Benchmark - Test Your Graphics Card Performance

A comprehensive online GPU benchmarking tool that tests your graphics card performance using WebGL. Run various tests including triangle rendering, particle systems, texture mapping, shader computations, and 3D scene rendering to measure your GPU's speed, FPS, and rendering capabilities. Perfect for testing gaming performance, graphics settings, and driver updates.

How does GPU benchmarking work?

GPU benchmarking measures graphics card performance by running standardized rendering tasks using WebGL:

1. Triangle Rendering: Tests basic geometry rendering
2. Particle System: Evaluates particle simulation and rendering
3. Texture Mapping: Tests texture processing and memory bandwidth
4. Complex Shaders: Measures shader compilation and execution
5. 3D Scene: Tests complete 3D rendering pipeline

Each test measures frames per second (FPS) and calculates a score based on rendering performance.

What factors affect GPU benchmark scores?

Several factors influence GPU benchmark results:

- GPU Model: Dedicated GPUs outperform integrated graphics
- VRAM: More video memory helps with high-resolution textures
- GPU Clock Speed: Higher MHz = faster rendering
- Driver Version: Updated drivers improve performance
- Browser: Different browsers have different WebGL performance
- Resolution: Higher screen resolution reduces FPS
- Background Processes: Other GPU-using apps affect scores
- Thermal Throttling: Overheating reduces GPU performance

For best results, close GPU-intensive applications, update drivers, and ensure good cooling.

What is a good GPU benchmark score?

Understanding your GPU benchmark results:

- Higher FPS = Smoother rendering
- Higher Score = Better overall performance

Typical scores by GPU tier:
- High-End Gaming GPU (RTX 4090, RX 7900 XTX): 10,000-20,000+
- Mid-Range Gaming GPU (RTX 4060, RX 7600): 5,000-10,000
- Entry-Level GPU (GTX 1650, RX 6500): 2,000-5,000
- Integrated Graphics (Intel UHD, AMD Vega): 500-2,000
- Mobile/Tablet: 100-1,000

Note: WebGL performance doesn't always match native gaming performance but gives a good relative comparison.

Why test GPU in browser?

Browser-based GPU benchmarks offer advantages:

- No Installation: Test immediately without downloads
- Cross-Platform: Works on Windows, Mac, Linux
- Safe: Runs in sandbox environment
- WebGL Testing: See how web-based 3D apps will perform
- Quick Results: Get scores in seconds
- Mobile Support: Test phones and tablets too

While not as comprehensive as native benchmarks like 3DMark or Unigine, browser tests are great for quick GPU diagnostics and WebGL performance evaluation.

What is WebGL?

WebGL (Web Graphics Library) is a JavaScript API for rendering interactive 2D and 3D graphics in web browsers without plugins.

WebGL enables:
- Hardware-accelerated 3D graphics in browser
- GPU-powered rendering and computations
- Games and 3D applications on the web
- Data visualization and simulations

This benchmark uses WebGL to directly test your GPU's rendering capabilities, measuring how well it handles:
- Vertex processing
- Fragment shading
- Texture operations
- Geometry rendering

All modern browsers support WebGL, making it perfect for cross-platform GPU testing.

Can I compare my results with others?

Yes! You can compare GPU benchmark scores:

1. Note your Overall Score and Average FPS
2. Compare with typical scores for your GPU model
3. Check if results match expected performance tier
4. Test on different browsers to see variations

Factors to consider when comparing:
- Screen resolution affects FPS
- Different browsers have different WebGL performance
- Driver versions matter significantly
- Background load affects results
- Mobile devices score much lower than desktops

For fairest comparison:
- Use same browser version
- Close all other applications
- Update graphics drivers
- Run test multiple times
- Compare with similar hardware configurations

Why are my GPU scores lower than expected?

Common reasons for lower GPU scores:

1. Integrated Graphics: Using CPU's integrated GPU instead of dedicated card
2. Power Saving: Laptop on battery mode
3. Outdated Drivers: Old graphics drivers reduce performance
4. Thermal Throttling: GPU overheating and reducing clock speed
5. Background Apps: Other programs using GPU (video editing, games)
6. Browser Limitations: Some browsers have slower WebGL
7. Hardware Acceleration Disabled: Check browser settings
8. High Resolution Display: 4K screens demand more GPU power

To improve scores:
- Enable dedicated GPU in system settings
- Plug in laptop (disable battery saving)
- Update graphics drivers
- Ensure proper cooling and ventilation
- Close GPU-intensive applications
- Enable hardware acceleration in browser
- Try different browser (Chrome usually performs best)
- Lower screen resolution for testing

Does this work on mobile devices?

Yes! This GPU benchmark works on mobile:

- Smartphones (iOS, Android)
- Tablets (iPad, Android tablets)
- Any device with WebGL support

Mobile GPU considerations:
- Much lower scores than desktop GPUs
- Aggressive thermal throttling
- Battery mode significantly affects performance
- Smaller screens may perform better
- Mobile GPUs prioritize efficiency over performance

Mobile GPU tiers:
- Flagship (Apple A17 Pro, Snapdragon 8 Gen 3): 1,000-3,000
- Mid-Range (Snapdragon 7 series): 500-1,000
- Budget (MediaTek, entry Snapdragon): 100-500

Mobile GPUs are optimized differently than desktop GPUs, so direct comparison isn't meaningful.

WebGL2 vs WebGL1 and how do I confirm hardware acceleration?

This tool prefers WebGL2 and falls back to WebGL1 when WebGL2 is unavailable. To trust a result you must confirm it ran on a real GPU, not a software fallback:

1. Check the Renderer field above. If it shows 'Google SwiftShader', 'ANGLE ... Software', 'llvmpipe' or 'Microsoft Basic Render Driver', your browser is rendering on the CPU — the score is NOT a valid GPU measurement (the tool shows a warning when it detects this).
2. In Chrome, open chrome://gpu to verify 'WebGL' and 'WebGL2' are 'Hardware accelerated'. In Firefox use about:support.
3. Enable 'Use hardware acceleration when available' in your browser settings, then restart the browser.
4. On laptops, force the dedicated GPU (not the integrated one) for the browser in your OS/driver settings.

A software renderer typically reports very low FPS across all five tests — that is the CPU emulating a GPU, not your graphics card.

How is the Score computed, and is it 3DMark-comparable?

FPS is measured directly (real frames per second over a ~2s window per test) — it is not faked. The per-test Score is FPS multiplied by a fixed per-test weight so heavier workloads count for more:

- Triangle Rendering: FPS x 100
- Particle System: FPS x 150
- Texture Mapping: FPS x 120
- Complex Shaders: FPS x 200
- 3D Scene: FPS x 180

The Overall Score is the average of the five per-test scores. Because the weights differ, the per-test Score column is only comparable within the same test, not across tests. These are relative WebGL fill/compute numbers and are NOT comparable to native benchmarks like 3DMark or Unigine — use them to compare the same device over time (e.g. before vs after a driver update) or similar devices in a QA batch.

Privacy note: the tool is 100% client-side and needs no permission. The Renderer/Vendor strings come from WEBGL_debug_renderer_info, which is a known fingerprinting signal and may be masked or hidden in privacy-focused browsers — if Renderer shows 'Unknown', that masking is why.

Repeatability for QA: run the benchmark several times and take the median (or the minimum, to catch thermal throttling between runs). Each run increments a run counter; use Export CSV/JSON to log every run with its exact GPU string and workload so you can diff devices in a spreadsheet or ticket.
