What is the difference between 32-bit and 64-bit?
32-bit computers support a maximum of 3-4GB of memory, whereas a 64-bit computer can support memory amounts over 4 GB. This is important for software programs that are used for graphical design, engineering design or video editing, where many calculations are performed to render images, drawings, and video footage.
As its name suggests, the 32 bit OS can store and handle lesser data than the 64 bit OS. More specifically, it addresses a maximum of 4,294,967,296 bytes (4 GB) of RAM. The 64 bit OS, on the other hand, can handle more data than the 32 bit OS.
Computers running 64-bit versions of Windows generally have more resources such as processing power and memory, than their 32-bit predecessors. Also, 64-bit applications can access more memory than 32-bit applications (up to 18.4 million Petabytes).
Here's the key difference: 32-bit processors are perfectly capable of handling a limited amount of RAM (in Windows, 4GB or less), and 64-bit processors can utilize much more. Of course, to achieve this, your operating system also needs to be designed to take advantage of the greater access to memory.
Using 64 bit operating system with 64 bit processer, the system can perform an increased number of calculations per second. As a result, it increases the processing power and makes a computer run faster. This is limited in case of 32 bit operating system. You can multi-task, switch between various application etc.
Disadvantages of 64-Bit Processor
More memory occupancy for small tasks: A 64-bit operating system computing takes up more memory space in comparison to 32-bit systems for the same data. This raises the need for more system memory and it may also affect how well the processor cache is used.
While 32-bit architectures are still widely-used in specific applications, the PC and server market has moved on to 64 bits with x86-64 since the mid-2000s with installed memory often exceeding the 32-bit 4G RAM address limits on entry level computers.
- Go to Start > Settings > System > About.
- Check the bit version under Device specifications > System type.
Better performance when moving data.
Since processors use 64 bits for both addressing and data, the processor can carry twice the amount of data carried by 32-bit processors in every clock cycle. This enables the processor to handle far more data and instructions per unit of time than previous processors.
| 32-bit | |
|---|---|
| Memory Limits | 32-bit systems are limited to 4 GB of RAM. |
| Cons | Less RAM access, less efficiency, fewer security features, PC's starting to get rid of 32-bit compatibility. Microsoft no longer making 32-bit copies |
What is the greatest advantage of using a 64 bit computer?
Benefits of 64-Bits:
The main perks gained from installing a 64-bit version of Windows are the ability to access RAM above the 4-GB range and the advanced security features. The access to more memory allows for more efficiency when administering processes and consequently improves performance of the OS.
The biggest advantage to using a 64-bit version is support for more than 4GB of memory (most 32-bit systems can use only about 3GB of memory). You would also choose a 64-bit version if you needed to run 64-bit applications or use hardware that had only 64-bit drivers.
In such cases, because a 64-bit operating system can handle large amounts of memory more efficiently than a 32-bit operating system, a 64-bit system can be more responsive when running several programs at the same time and switching between them frequently.
IMPORTANT: Backup Important Files on 32-Bit OS. As for upgrading 32-bit OS to 64-bit OS, installing 64-bit programs on a 32-bit computer, or daily operations on computers may cause data loss, so do remember to back up your vital data and even the OS before taking action.
Choosing Between 32-Bit and 64-Bit Software
Heavy programs, like video editors and high-end games, run better in their 64-bit versions. Multi-tasking becomes more efficient, too. On a 64-bit system, if you have a choice between 32-bit and 64-bit apps, always go with 64-bit for best performance.
Microsoft has stated that future versions of Windows 10, starting with the May 2020 Update, will no longer be available as 32-bit builds on new OEM computers.

To oversimplify it, you're choosing between compatibility and performance. Windows 10 32-bit is more likely to work with older hardware and software, but you'll miss out on some of the performance and feature benefits that are only available in Windows 10 64-bit.
Microsoft's Windows 11 operating system is 64-bit supported only. This means that only PCs with a 64-bit processor can run Windows 11. Also, because 32-bit Windows 11 is unavailable, PC users running a 32-bit Windows 10 cannot directly upgrade to Windows 11.
Memory in 32 and 64-Bit Architectures
In terms of Random Access Memory, 32-bit architectures can address 4GB of memory, maximum. A 64-bit architecture, in turn, has a theoretical limit of addressing 16 million TB of memory.
How do I know if I am 64-bit?
On the “System” page, look for the “System type” entry to see whether your operating system is 32-bit or 64-bit.
In conclusion, 32-bit operating systems are less utilized nowadays as compared to 64-bit operating systems. However, 64-bit is preferred because it is faster, has more memory, and can present graphics better than 32-bit.
A 64-bit architecture, in turn, has a theoretical limit of addressing 16 million TB of memory. This difference in memory support comes from the number of different addresses expressable in a single memory word. We should remember that a computer fully maps its memory, byte by byte.
To put it in simple words, if you run a 32-bit program on a 64-bit machine, it will work fine, and you won't encounter any problems. Backward compatibility is an important part when it comes to computer technology. Therefore, 64 bit systems can support and run 32-bit applications.
Certainly. In fact, a 64bit OS makes less than zero sense with systems with less than 4GB of RAM. And, 32bit OS's use less resources at idle (or at any other time, for that matter), typically about 150MB less.
A 32-bit OS, for example, has more limitations—the standout being it can only really utilize 4GB of RAM. Installing more RAM on a system with a 32-bit OS doesn't have much impact on performance. However, upgrade that system with excess RAM to the 64-bit version of Windows, and you'll notice a difference.
2GB of RAM is the minimum system requirement for the 64-bit version of Windows 10.
Is 8GB RAM enough for Windows 11? Windows 11 RAM requirement is 4GB. 8GB RAM can run Windows 11 and some other basic software. But if you want to run some productive software, 8GB is not enough.
What are the RAM limits of a 32-bit operating system? All 32-bit operating systems have a 4GB RAM limit.
IMPORTANT: Backup Important Files on 32-Bit OS. As for upgrading 32-bit OS to 64-bit OS, installing 64-bit programs on a 32-bit computer, or daily operations on computers may cause data loss, so do remember to back up your vital data and even the OS before taking action.
Is Windows 11 64-bit?
Has a 64-bit CPU: Windows 11 can only run on 64-bit CPUs. To see if your PC has one, go to Settings > System > About, or search “System Information” in Windows and look under “System Type.” Windows 11 Media Creation Tool creates installation media only for x64 processors.
