System Information
View your device's hardware information detected by your browser.
How to Use This Test
- Open this page on the device you want to check -- the test runs automatically
- Review the detected hardware details including CPU cores, GPU renderer, and memory
- Check your screen resolution, color depth, and browser information
What This Test Checks
The system info test uses browser APIs to detect and display key hardware and software details about your device. It provides a quick overview without installing any software.
- CPU information -- logical processor count and platform architecture
- GPU renderer -- graphics card details via the WebGL API
- Memory -- approximate system RAM reported by the Device Memory API
- Display properties -- screen resolution, pixel ratio, and color depth
- Browser and OS -- user agent, language, and connection information
Troubleshooting
If you're having issues with the system info test:
- Enable JavaScript if your browser has it disabled -- the test requires it to function
- Try Chrome or Edge for the most complete hardware detection, as some browsers limit API access
- Disable privacy extensions temporarily if they block WebGL or Device Memory APIs
- If GPU info shows as unknown, check that hardware acceleration is enabled in your browser settings
Frequently Asked Questions
Why can't the test detect my exact CPU or GPU model?
Browsers intentionally limit the hardware details exposed through JavaScript for privacy and security reasons. The test can detect general capabilities like core count and GPU renderer, but exact model names may be hidden or generalized depending on your browser and OS settings.
Is the RAM amount shown accurate?
The browser's Device Memory API reports an approximate value (e.g., 4, 8, or 16 GB) rather than an exact figure. This is by design to prevent fingerprinting. The actual amount of installed RAM on your system may differ slightly from the reported value.
Does this test install anything on my device?
No. This system info test runs entirely in your web browser using standard JavaScript APIs. It does not install software, download executables, or require any special permissions. All detection happens client-side and no data is sent to any server.
Why does GPU information show as 'unknown' or 'blocked'?
Some browsers block the WebGL renderer info extension by default to prevent device fingerprinting. Firefox, in particular, may hide this information. You can try enabling hardware acceleration in your browser settings or testing in Chrome for more detailed GPU information.
