Browser system, CPU and GPU test

See the hardware and graphics capabilities your browser can actually use, then run a short local rendering check without installing software.

System details are read and processed locally. This page does not upload a hardware fingerprint or claim access the browser does not provide.

How to test

  1. Review the browser, display and logical processor summary.
  2. Check WebGL or WebGPU capability details.
  3. Run the short rendering test and compare only on the same browser and power mode.

What it checks

  • Logical CPU thread count
  • Approximate memory when available
  • WebGL and WebGPU capability
  • Display and pixel-density details
  • Short browser rendering benchmark

Frequently asked questions

Can a website read my exact CPU model and temperature?

Usually no. Browsers expose logical thread count and selected graphics capabilities, but intentionally hide exact CPU model, temperature, utilization, driver and VRAM details.

Is this a full GPU stress test?

No. It is a lightweight browser rendering check designed to reveal obvious capability or frame-delivery issues, not a thermal or stability certification.
