How to Determine if Your Processor is ARM64 or x64 (64-bit) on Windows 11

How to Identify Your Windows 11 Processor: x64 vs. ARM64

Last Updated: October 24, 2025

Recognizing whether your Windows 11 PC operates on an x64 or ARM64 architecture is essential for software compatibility and optimal performance. In this article, we will explore multiple methods to determine your processor type using the built-in features of Windows 11.

Why Does Processor Architecture Matter?

Both x64 and ARM64 support a 64-bit architecture, which is necessary for running Windows 11 and its applications. However, the x64 architecture, predominantly seen in Intel and AMD processors, offers greater compatibility with traditional desktop applications. Conversely, the ARM64 architecture, primarily utilized in processors by manufacturers such as Qualcomm, is emerging in mobile and lightweight computing but may present limitations when installing conventional desktop software.

Steps to Check Your Processor Type

Windows 11 provides several straightforward methods to verify if your processor is x64 or ARM64. Below, we outline three different procedures using the Settings app, System Information, and Command Prompt.

Using the Settings App
Via System Information
Through Command Prompt

Using the Settings App

Follow these steps to discover your processor type through the Settings application:

Open Settings.
Navigate to System.
Click on About.
In the “Device specifications” section, locate the “System type”. It will indicate either “64-bit operating system, x64-based processor” or “64-bit operating system, ARM-based processor”.

Upon completion, you will see whether your PC is powered by an ARM64 or x64 processor.

Via System Information

To check your processor type using System Information, follow these instructions:

Access the Start menu.
Search for System Information and select it from the search results.
Click on Summary.
Look for “System Type”. It should display either “x64-based PC” or “ARM-based PC”.

Once you complete these steps, the System Information window will reveal the specific type of processor in your machine.

Through Command Prompt

To identify your processor type using Command Prompt, please proceed with the following steps:

Open the Start menu.
Search for Command Prompt and run it as an administrator.
Input the following command and hit Enter:

systeminfo | findstr /C:"System Type"

Observe the “System Type” information as it will indicate either “x64-based PC” or “ARM-based PC”.

Command Prompt check processor x64 or ARM64

By completing these steps, you will gain clarity on your computer’s processor architecture.

Note that this guide does not discuss x86 as Windows 11 does not support 32-bit systems.
