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

Computer CPU

The steps to determine whether your figurer has a 32-flake or 64-scrap processor (CPU) depend on the operating system installed. Beneath are the steps to determine the processor type for Windows, Mac, and Linux.

Windows 8, 10, and 11

See the following steps to make up one's mind your CPU type and how many $.25 the processor has in Windows 8, Windows 10, and Windows 11.

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

Or, if you do not have a search box (because yous have disabled it):

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

Properties in File Explorer.

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

Find your System type.

Tip

To determine the processor'south manufacturer (due east.thou., AMD or Intel) and its model, come across the Processor line.

Before versions of Windows

With earlier versions of Windows, follow these steps.

  1. Open the Start bill of fare > All Programs. Open the Accessories folder, and then the Organisation Tools binder. In the System Tools binder, select the Arrangement Information choice.

System Information - 64-bit CPU

  1. Wait for the System Type selection under the Item cavalcade on the right side of Arrangement Information. In the Value column, the associated value tells you which blazon of CPU the estimator has in it. If the Organisation Type value includes "x86" in it, the CPU is 32-scrap. If the System Type value includes "x64" in it, the CPU is 64-chip.

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

Microsoft Windows is available in 64-flake and 32-bit. 32-chip processors can only run 32-bit versions of Windows. Yet, 64-bit processors can run either the 64-chip or 32-scrap versions.

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

  • Windows Vista and subsequently
  • Windows XP
  • Windows 2000 and prior

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

  1. Press and concur the Windows key and the Intermission key.

Tip

Some laptops don't have a Pause key. Instead, the Interruption key is a secondary role of a office key, and y'all need to printing the Fn key and that function key.

  1. The Arrangement window, adjacent to Organization type, lists 32-bit Operating System for a 32-bit version of Windows and 64-scrap Operating Arrangement if you're running the 64-bit version. Beneath is a motion picture and an example of this window.

64-bit version of Windows system information

Make up one's mind if Windows XP is 32-bit or 64-bit

  1. Press and hold the Windows key and the Pause primal, 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 computer runs the 32-flake version of Windows XP. If it has the text Windows XP Professional x64 Edition, the calculator runs the 64-scrap version of Windows XP.

Make up one's mind if Windows 2000 and prior is 32-bit or 64-bit

Windows operating systems, from Windows 95 to Windows 2000, are all 32-chip. At that place are no 64-flake versions of these operating systems.

Apple tree macOS

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

  1. Click the Apple tree icon in the menu bar at the upper-left corner.
  2. Select the About This Mac choice in the Apple menu.
  3. On the About This Mac window, click the More Info choice.
  4. Open the Hardware department and find the Processor Name aspect. Once listed, perform an Net search, using the CPU's processor name every bit a keyword, to determine if it's a 32-fleck or 64-bit CPU.
Processor 32-bit or 64-fleck
Intel Cadre Duo or Solo 32-fleck
Intel Core 2 Duo 64-bit
Any Intel Xeon processor 64-fleck
Intel Core i3 64-bit
Intel Core i5 64-bit
Intel Core i7 64-bit

The table above shows that all the most contempo Mac computers are 64-flake processors.

Linux

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

grep flags /proc/cpuinfo

Expect for "lm" in the command output. If lm is establish in the output, then the CPU is 64-bit. If you don't meet lm or see i386, i486, i586, or i686 in the output, and then 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

Determine if the Linux kernel is 32-flake or 64-flake

Using the uname command, you can make up one's mind if your Linux kernel is 32-scrap or 64-bit past running the command below.

uname -a

The control 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, information technology is x86 and 64-bit.
