Description
About CPU Information
Introduction
This page shows the number of logical processors the browser is willing to report, plus optional architecture hints. Browsers do not give web pages your CPU’s marketing model (for example “Ryzen 7 …” or “M3 Pro”). That protects privacy and is an intentional platform limit.
What this tool does
It displays hardware concurrency and, when available, simple architecture/bitness hints. It does not benchmark speed or list core temperatures.
When to use it
Use it to see what the web platform exposes for thread counts. Use your OS system info for the real CPU model and clocks.
How it works
Supported: concurrency on virtually all modern browsers. Optional architecture hints: mainly Chromium with Client Hints. Unsupported: a reliable SKU/model string in every browser. Permissions: none. Hardware: any PC or phone; counts may be privacy-clamped. Expected: a core/thread style number, not a full CPU datasheet.
Step-by-step instructions
- Open CPU Information.
- Read the logical processor count.
- If architecture hints appear, treat them as optional.
- Confirm the marketing model in your operating system if needed.
Common problems
Counts lower than Task Manager can be privacy clamping. Missing model name is normal for the web.
Privacy explanation
Only coarse hardware hints are read. Nothing is uploaded.
