How to determine if you have a 32-fleck or 64-fleck CPU

Computer CPU

The steps to determine whether your computer has a 32-bit or 64-chip processor (CPU) depend on the operating organisation installed. Beneath are the steps to make up one's mind the processor blazon for Windows, Mac, and Linux.

Windows eight, 10, and eleven

See the following steps to determine your CPU blazon and how many bits the processor has in Windows 8, Windows 10, and Windows 11.

  • Type system data in the Windows search box and select the System Information icon.

Or, if you lot do not accept a search box (because y'all have disabled it):

  1. Open a File Explorer window by pressing Windows cardinal+E.
  2. On the left, right-click This PC.
  3. In the context menu, select Backdrop to open up the Organisation Properties window.

Properties in File Explorer.

  1. In the Arrangement Properties window, find your Organization type, which lists your operating system and CPU type.

Find your System type.

Tip

To determine the processor'due south manufacturer (e.g., AMD or Intel) and its model, see the Processor line.

Earlier versions of Windows

With earlier versions of Windows, follow these steps.

  1. Open the Start menu > All Programs. Open the Accessories folder, and then the System Tools folder. In the System Tools folder, select the System Information option.

System Information - 64-bit CPU

  1. Look for the System Type option under the Item column on the right side of Arrangement Information. In the Value column, the associated value tells y'all which type of CPU the computer has in it. If the System Type value includes "x86" in it, the CPU is 32-chip. If the Arrangement Type value includes "x64" in it, the CPU is 64-bit.

Make up one's mind if using 32-bit or 64-bit version of Windows

Microsoft Windows is available in 64-fleck and 32-bit. 32-scrap processors tin but run 32-bit versions of Windows. Even so, 64-chip processors can run either the 64-bit or 32-bit versions.

To decide if the version of Windows on your estimator is 32-bit or 64-scrap, choose your version and follow the steps.

  • Windows Vista and after
  • Windows XP
  • Windows 2000 and prior

Determine if Windows Vista and later is 32-bit or 64-bit

  1. Printing and hold the Windows cardinal and the Interruption key.

Tip

Some laptops don't take a Pause fundamental. Instead, the Pause cardinal is a secondary office of a function key, and you demand to press the Fn key and that role key.

  1. The System window, next to System blazon, lists 32-bit Operating System for a 32-bit version of Windows and 64-fleck Operating System if y'all're running the 64-fleck version. Below is a picture and an example of this window.

64-bit version of Windows system information

Determine if Windows XP is 32-chip or 64-flake

  1. Press and hold the Windows key and the Suspension key, or open up the Organization icon in the Control Panel.
  2. On the Full general tab of the System Properties window, if information technology has the text Windows XP, the computer runs the 32-bit version of Windows XP. If it has the text Windows XP Professional x64 Edition, the calculator runs the 64-bit version of Windows XP.

Determine if Windows 2000 and prior is 32-flake or 64-fleck

Windows operating systems, from Windows 95 to Windows 2000, are all 32-bit. There are no 64-flake versions of these operating systems.

Apple tree macOS

On a macOS calculator, follow these steps to decide if the processor is 32-bit or 64-chip.

  1. Click the Apple icon in the card bar at the upper-left corner.
  2. Select the Virtually This Mac option in the Apple bill of fare.
  3. On the About This Mac window, click the More Info pick.
  4. Open the Hardware section and find the Processor Proper noun attribute. Once listed, perform an Net search, using the CPU's processor proper noun equally a keyword, to determine if it's a 32-bit or 64-fleck CPU.
Processor 32-flake or 64-scrap
Intel Core Duo or Solo 32-fleck
Intel Core ii Duo 64-scrap
Any Intel Xeon processor 64-flake
Intel Core i3 64-fleck
Intel Core i5 64-bit
Intel Core i7 64-bit

The table to a higher place shows that all the almost contempo Mac computers are 64-scrap processors.

Linux

Access the command line interface on the Linux operating system, and enter the following command.

grep flags /proc/cpuinfo

Wait for "lm" in the command output. If lm is found in the output, then the CPU is 64-bit. If you don't encounter lm or see i386, i486, i586, or i686 in the output, and so the CPU is 32-bit. Below is an example output of the command above with lm in the information.

flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx            lm            constant_tsc arch_perfmon pebs bts rep_good pni monitor ds_cpl est tm2 ssse3 cx16 xtpr sse4_1 lahf_lm

Decide if the Linux kernel is 32-scrap or 64-bit

Using the uname command, you lot tin determine if your Linux kernel is 32-bit or 64-bit past running the control below.

uname -a

The command above displays an output similar to the example output beneath.

SMP Tue Feb 12 00:15:43 EST 2008            x86_64            x86_64 GNU/Linux

If you see x86_64 in the output, it is x86 and 64-bit.
