About the system specs
Updated
The system specs page collects everything your browser exposes about your device: operating system and version, CPU thread count, graphics renderer, approximate memory, screen resolution and pixel ratio, browser, language, time zone and connection type. You can copy or export it as JSON to attach to a support ticket or bug report.
How to use it
- Open the page and wait for detection to finish.
- Review each section: OS, CPU, graphics, memory, screen and browser.
- Export the result as JSON if you need to share it.
Frequently asked questions
Why does it show 8 GB of memory when I have more?
Browsers round device memory and cap it at 8 GB for privacy, so the real figure may be higher.
Why is my graphics card shown as a generic name?
Some browsers, especially Firefox and Safari, hide the exact GPU model to prevent fingerprinting and report a generic renderer instead.
Is CPU threads the same as cores?
No. The browser reports logical threads. A CPU with hyper-threading usually has half as many physical cores.
