32 Bit vs 64 Bit: Which One Should You Choose?

When you’re buying a new computer or downloading software, you might notice there are often two versions available: 32-bit and 64-bit. At first glance, the difference might seem minimal, but understanding these two system types can impact your device’s performance and overall experience. So, which one should you choose—32-bit or 64-bit?

This guide will break down the differences between 32-bit and 64-bit systems, helping you decide which option is right for you based on performance, compatibility, and more.

What Is a 32-Bit Operating System?

A 32-bit operating system refers to a computer system's ability to process data in 32-bit chunks. This means that a CPU with a 32-bit architecture can handle 32 bits of data at a time. In the early 2000s, most computers used 32-bit processors. These systems could support up to 4GB of RAM, although they typically accessed only about 3.5GB due to system constraints.

A 32-bit OS is now largely outdated, but it was the standard for decades. However, it’s still used in some older systems and specific applications that require less processing power.

What Is a 64-Bit Operating System?

A 64-bit operating system can process data in 64-bit chunks, allowing it to handle significantly more information at once compared to a 32-bit system. This increase in data-processing capability translates to better performance, especially when running multiple applications simultaneously or handling large amounts of data.

The key benefit of a 64-bit system is its ability to use more than 4GB of RAM. In fact, a 64-bit processor can theoretically handle up to 16 exabytes (17.2 billion GB) of RAM, though most modern systems max out at a more practical 2TB of RAM. Additionally, 64-bit processors are backward compatible, meaning they can run both 32-bit and 64-bit operating systems.

32-Bit vs 64-Bit: Key Differences

Now that you know the basics, let’s compare 32-bit and 64-bit systems across several key areas.

1. Compatibility

• 32-Bit Systems: Older computers often run on 32-bit processors, meaning they can only use 32-bit operating systems and software. If you need to run legacy software or older games, a 32-bit system might be your only option. However, it cannot run 64-bit software.

• 64-Bit Systems: A 64-bit processor can run both 32-bit and 64-bit software, making it much more versatile. However, older programs, such as 16-bit applications, won’t run on a 64-bit system without an emulator.

Verdict: If you’re working with modern software or future-proofing, 64-bit is the clear winner.

2. Performance

• 32-Bit Systems: Limited to 4GB of RAM, 32-bit systems struggle to handle multitasking and modern software, especially for graphics-intensive tasks like gaming or video editing.

• 64-Bit Systems: With access to significantly more RAM and more processing cores, 64-bit systems excel at multitasking, data processing, and running complex applications. This is especially useful for high-end gaming, data analysis, and professional-grade software.

Verdict: For enhanced performance, particularly in multitasking and resource-heavy applications, 64-bit systems are superior.

3. Security

• 32-Bit Systems: Older and less secure, 32-bit systems are more vulnerable to malware. They lack many of the security enhancements found in modern operating systems.

• 64-Bit Systems: These systems come with advanced security features, such as driver signing, which ensures that drivers have been verified by the OS. The 64-bit architecture also restricts how 32-bit applications interact with the OS, preventing many types of malware from running.

Verdict: A 64-bit system offers better security and protection against modern threats.

4. Software Availability

• 32-Bit Systems: Some software is still available in 32-bit versions, particularly older applications or those designed for minimal resource use. However, most modern software is transitioning to 64-bit only.

• 64-Bit Systems: A 64-bit system can run virtually all modern software, and as developers increasingly move away from 32-bit architecture, 64-bit compatibility is becoming the standard.

Verdict: If you want access to the latest software and features, a 64-bit system is the best choice.

5. Operating System Support

• 32-Bit Systems: Most older operating systems like Windows XP and early versions of Windows 7 offer 32-bit options. However, Microsoft has ceased development of 32-bit systems with the release of Windows 11. Similarly, Mac and Linux have also phased out 32-bit support in favor of 64-bit.

• 64-Bit Systems: Modern operating systems, including Windows 10, Windows 11, MacOS, and Linux distributions, are primarily available as 64-bit versions.

Verdict: If you’re using modern operating systems, you’ll need a 64-bit system.

How to Check If Your System Is 32-Bit or 64-Bit

Wondering which version of an OS your device is running? Here’s a quick guide to checking whether your system is 32-bit or 64-bit:

Windows

1. Open File Explorer (Windows + E).

2. Right-click This PC and select Properties.

3. Look for the System Type section, which will tell you if your system is 32-bit or 64-bit.

Linux

1. Click the System menu (gear icon).

2. Select System Settings.

3. Navigate to Details and look for the OS Type to see if it’s 32-bit or 64-bit.

Mac

1. Open the Apple menu and click About This Mac.

2. Select System Report.

3. Check the Processor Name to see if it’s a 32-bit or 64-bit system.

Android

1. Download a third-party app like CPU-Z or AIDA64 from the Play Store.

2. Check the app’s system information for the kernel architecture.

32-Bit vs 64-Bit in Mobile Devices

Mobile technology has also made the shift from 32-bit to 64-bit. Apple’s iPhone 5S, released in 2013, was the first smartphone to support a 64-bit processor. Since then, all iPhones and iPads have been running on 64-bit architectures. Similarly, most modern Android phones now run 64-bit operating systems.

However, unlike desktop systems, the move to 64-bit in mobile devices isn’t solely about RAM. Instead, it improves data processing, application launch times, and overall performance.

Conclusion: Should You Choose 32-Bit or 64-Bit?

In today’s computing world, 64-bit systems are the clear winner. They offer better performance, enhanced security, and access to the latest software and operating systems. While 32-bit systems were once the standard, they are quickly becoming obsolete as more software and hardware are designed with 64-bit architecture in mind.

If you’re still using a 32-bit system, it might be time for an upgrade. Most modern computers come with 64-bit processors, and upgrading your operating system to 64-bit is relatively simple if your hardware supports it. By making the switch, you’ll future-proof your system and enjoy faster, more efficient computing.

You can switch to a professional version of Windows 11 with a clean installation and choose the 64-bit option. You can buy a retail Windows 11 Pro Key at 3,7$ here.
