CPU Test

Run a short single-core and multi-core processor benchmark and get a clear browser-based CPU score.

Instant result No sign-up Runs in your browser
Ready when you are

Close heavy apps, then run the short processor benchmark.

Local only
CPU browser scoreready for a two-pass benchmark

The workload runs locally in browser workers. It does not reveal processor temperature, clock speed or the exact CPU model.

01

How to use this test

  1. Close demanding apps or downloads for a cleaner result.
  2. Select Run CPU benchmark and keep this tab open.
  3. Compare single-core speed, multi-core throughput and your browser score.
02

If something looks wrong

  • Repeat the test after your device has cooled down.
  • Turn off battery saver when comparing maximum performance.
  • Compare results in the same browser because browser engines affect the score.
Quick answers

Good to know.

Is this a real CPU benchmark?+

It is a real timed JavaScript workload executed in isolated browser workers. It is useful for comparing the same device and browser, but it is not a replacement for a native hardware benchmark.

Can this test identify my exact processor?+

No. Browsers expose the number of available logical processors but normally hide the exact CPU model, clock speed and temperature for privacy.

Why does my CPU score change?+

Temperature, battery mode, background apps, browser version and power management can all change short benchmark results.
