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

Updated: 03/12/2022 past Figurer Hope

Computer CPU

The steps to determine whether your figurer has a 32-chip or 64-fleck processor (CPU) depend on the operating system installed. Below are the steps to determine the processor blazon for Windows, Mac, and Linux.

Windows eight, ten, and 11

See the post-obit steps to make up one's mind your CPU type and how many bits the processor has in Windows eight, Windows 10, and Windows 11.

  • Blazon arrangement information in the Windows search box and select the System Information icon.

Or, if yous practice not take a search box (because you have disabled information technology):

  1. Open up a File Explorer window past pressing Windows key+E.
  2. On the left, right-click This PC.
  3. In the context carte du jour, select Properties to open the Organization Properties window.

Properties in File Explorer.

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

Find your System type.

Tip

To determine the processor's manufacturer (eastward.g., AMD or Intel) and its model, meet the Processor line.

Earlier versions of Windows

With earlier versions of Windows, follow these steps.

  1. Open the Start menu > All Programs. Open up the Accessories binder, then the System Tools binder. In the Organization Tools folder, select the System Information choice.

System Information - 64-bit CPU

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

Determine if using 32-scrap or 64-bit version of Windows

Microsoft Windows is bachelor in 64-bit and 32-bit. 32-chip processors tin can only run 32-bit versions of Windows. However, 64-fleck processors can run either the 64-bit or 32-fleck versions.

To determine if the version of Windows on your computer is 32-bit or 64-scrap, cull your version and follow the steps.

  • Windows Vista and later on
  • Windows XP
  • Windows 2000 and prior

Decide if Windows Vista and after is 32-bit or 64-bit

  1. Press and concur the Windows key and the Break cardinal.

Tip

Some laptops don't accept a Pause fundamental. Instead, the Interruption key is a secondary function of a function central, and yous need to press the Fn key and that function cardinal.

  1. The Arrangement window, next to System type, lists 32-bit Operating System for a 32-bit version of Windows and 64-bit Operating System if yous'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-bit or 64-fleck

  1. Press and hold the Windows primal and the Intermission key, or open the System icon in the Control Panel.
  2. On the General tab of the System Properties window, if it has the text Windows XP, the reckoner runs the 32-bit version of Windows XP. If information technology has the text Windows XP Professional person x64 Edition, the computer runs the 64-scrap version of Windows XP.

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

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

Apple macOS

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

  1. Click the Apple icon in the menu bar at the upper-left corner.
  2. Select the Near This Mac option in the Apple menu.
  3. On the Well-nigh This Mac window, click the More than Info option.
  4. Open up the Hardware section and discover the Processor Proper name attribute. In one case listed, perform an Internet search, using the CPU'due south processor name as a keyword, to determine if information technology's a 32-bit or 64-fleck CPU.
Processor 32-bit or 64-bit
Intel Core Duo or Solo 32-bit
Intel Cadre 2 Duo 64-bit
Any Intel Xeon processor 64-flake
Intel Core i3 64-bit
Intel Cadre i5 64-bit
Intel Core i7 64-bit

The tabular array above shows that all the most recent Mac computers are 64-bit processors.

Linux

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

grep flags /proc/cpuinfo

Look for "lm" in the command output. If lm is found in the output, and then the CPU is 64-fleck. If yous don't see lm or see i386, i486, i586, or i686 in the output, and so the CPU is 32-chip. Beneath 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

Make up one's mind if the Linux kernel is 32-bit or 64-bit

Using the uname command, you can determine if your Linux kernel is 32-fleck or 64-fleck by running the control below.

uname -a

The command to a higher place displays an output similar to the example output below.

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.
