ARM vs. x86 and 32-bit vs. 64-bit
Your CPU architecture is shown in the result: whether your processor is ARM or x86, and whether it runs 64-bit or 32-bit. Your browser shares this through User-Agent Client Hints, so it is accurate even on Apple silicon Macs, which still claim to be Intel in the user agent.
ARM vs. x86
- x86: the processor family made by Intel and AMD, used in most Windows PCs and in Macs before 2020.
- ARM: the energy-efficient family used in Apple silicon Macs (M1 and later), Snapdragon Windows laptops, and almost every phone and tablet.
Apps built for one architecture don’t run natively on the other. Apple’s Rosetta 2 and Windows’ built-in emulation can run x86 apps on ARM, usually more slowly.
32-bit vs. 64-bit
64-bit processors can use far more memory and are standard on every current computer and phone. A 32-bit result usually means an older device, or a 32-bit operating system or browser installed on 64-bit hardware.

The tool works in Chrome, Edge, Opera and other Chromium-based browsers. Your exact OS version helps too: some apps need a minimum version of Windows or macOS.
