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

Updated: 03/12/2022 past Computer Hope

Computer CPU

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

Windows eight, x, and 11

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

  • Blazon system information in the Windows search box and select the Organisation Data icon.

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

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

Properties in File Explorer.

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

Find your System type.

Tip

To determine the processor's manufacturer (e.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 Outset bill of fare > All Programs. Open the Accessories binder, and then the System Tools folder. In the Arrangement Tools binder, select the System Information pick.

System Information - 64-bit CPU

  1. Look for the System Type option under the Item column on the correct side of Arrangement Information. In the Value cavalcade, the associated value tells you which type of CPU the computer has in information technology. If the System Type value includes "x86" in it, the CPU is 32-scrap. If the System Type value includes "x64" in it, the CPU is 64-fleck.

Decide if using 32-fleck or 64-bit version of Windows

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

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

  • Windows Vista and afterward
  • Windows XP
  • Windows 2000 and prior

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

  1. Press and agree the Windows key and the Break key.

Tip

Some laptops don't take a Pause primal. Instead, the Pause key is a secondary function of a function key, and yous need to printing the Fn primal and that function cardinal.

  1. The System window, next to Organization blazon, lists 32-scrap Operating System for a 32-fleck version of Windows and 64-scrap Operating Arrangement if you're running the 64-scrap version. Below is a moving-picture show and an case of this window.

64-bit version of Windows system information

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

  1. Press and hold the Windows fundamental and the Break primal, or open the Organization icon in the Control Panel.
  2. On the Full general tab of the System Properties window, if it has the text Windows XP, the computer runs the 32-scrap version of Windows XP. If it has the text Windows XP Professional x64 Edition, the estimator runs the 64-scrap version of Windows XP.

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

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

Apple macOS

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

  1. Click the Apple tree icon in the carte du jour bar at the upper-left corner.
  2. Select the About This Mac selection in the Apple bill of fare.
  3. On the Nigh This Mac window, click the More Info option.
  4. Open up the Hardware section and notice the Processor Name aspect. Once listed, perform an Cyberspace search, using the CPU's processor name as a keyword, to determine if it's a 32-fleck or 64-scrap CPU.
Processor 32-bit or 64-bit
Intel Cadre Duo or Solo 32-bit
Intel Core 2 Duo 64-fleck
Any Intel Xeon processor 64-flake
Intel Core i3 64-bit
Intel Core i5 64-scrap
Intel Core i7 64-bit

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

Linux

Access the command line interface on the Linux operating arrangement, and enter the post-obit command.

grep flags /proc/cpuinfo

Wait for "lm" in the command output. If lm is institute in the output, then the CPU is 64-bit. If you don't see lm or meet i386, i486, i586, or i686 in the output, and then the CPU is 32-flake. Below is an instance output of the command above with lm in the data.

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 control, you tin make up one's mind if your Linux kernel is 32-bit or 64-bit by running the command below.

uname -a

The command above 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-flake.
