Difference Between 32-Bit vs 64-Bit operating system
In computer architecture 32-bit integers, memory addresses and data units are used. 64-bit computing makes use of processors which specify different data path widths, integer size, and memory addresses which have a width of 64-bits. They are the central processing unit for any computer. It also specifies the driver and software program which utilize the particular architecture. There is different software which supports both these architectures and choosing does make a difference if the two were programmed for different systems. The 32-bit hardware and software are often referred to as x86 or x86-32. The 64-bit hardware and software are referred to as x64 or x86-64. Let’s have a look at other differences between 32-Bit vs 64-Bit operating system in detail.

Key Differences Between 32-Bit vs 64-Bit Operating System
Both 32-Bit vs 64-Bit operating system is popular choices in the market. let us discuss some of the major Difference Between 32-Bit System vs 64-Bit System:
- To just begin with the comparison and simply putting it we can say that a 64-bit processor is more capable than a 32-bit one. It can handle more data at once. In addition to this, it has the ability to store more data, storing more computational values, including memory addresses which helps in accessing approximately four billion times the physical memory that a 32-bit processor can access.
- A 32-bit processor can easily handle a limited amount of RAM. This can be considered as 4GB. 64 bit systems, on the other hand, can access much more. It is important to have this as the operating system should be designed in a way by which it can access more memory. The basic version of operating systems has its limitations on RAM which can be utilized by applications. $GB is the maximum which can be utilized by a 32-bit system. The latest versions of the 64-bit system have the capability of increasing the capabilities of the processor. The applications like video games with high performance demand high memory and this is where 64-bit systems come out to be superior.
- If you are a Windows user you would have noticed two folders in Program files. One as Program files and the other as Program Files (x86). The 32-bit architecture though being old has been there for a long time. There are many applications that host and utilize 32-bit architecture. The new systems which have 64-bit systems have the capability of running 32-bit and 64-bit software together. Hence they have two different directories for both. When a 32-bit application is encountered it is moved to the x86 folder and the other folder when 64-bit is encountered.
- By using a 64-bit system a lot of multi-tasking is possible. The user can easily switch between the different applications without any glitches. The games demanding high performance and the applications that consume a lot of memory can run easily on a 64-bit processor.
32-Bit vs 64-Bit Operating System Comparison Table
Below is the topmost comparison between 32-Bit vs 64-Bit operating system:
|The Basis Of Comparison between 32-Bit vs 64-Bit Operating System||
|Architecture||The 32-bit system has general computing which includes IBM System/360 and IBM System/370, the DEC VAX, the Motorola 68000 Family, the Intel IA-32, 32-bit version of x86 architecture are the different versions. These are architectures which are used for embedded computing and include 68000 families.||The registers are divided into different groups like integer, floating, control and often for addresses of various uses and names like address, index or base registers. The size of these registers is dependent on the amount of addressable memory.|
|Hardware||A 32-bit system consists of a 32-bit register. This register is capable of storing 232 or 4,294,967,296 values. A 32-bit system can address up to 4GB of RAM. The actual can be thought of as 3.5 GB. This is because a part of registry stores temporary values with the memory addresses.||A 64-bit system consists of 64-bit register which is capable of holding 264 or 18,446,744,073,709,551,616 values. A 64-bit register has the capability of addressing around 16 exabytes of memory. It can clearly access more than 4GB of RAM. If a computer has 16GB RAM then it is better than the system is a 64-bit system. 64-bit systems remove all bottlenecks that are present in 32-bit systems. They run more efficiently and have data paths and memory blocks already allocated.|
|Software||32-bit programs are compatible with 64-bit systems. But vice versa is not possible. The software is also built for 32-bit systems but is seldom used. It is possible to install a 32-bit system on a 64-bit system. There are utilities or anti-virus software which are specifically written for 32-bit systems. It is advisable to download the ones which correspond to your system. Also, device drivers are also written for specific operating systems and hence it is important to install a 32-bit for its corresponding 32 drivers.||Backward compatibility is not supported by 64-bit systems. This is because 64-bit instructions cannot be recognized by a 32-bit processor. All new systems are 64-bit versions of Windows and OS X. The 64-bit version allows accessing more RAM than 32-bit.|
|Calculations per second||32-bit systems have dual core and quad core versions available.||64bit systems can come with dual core, quad core, six core, and eight core versions. Having these multiple cores available has increased its speed of calculations per second.|
If you are installing any operating system it is very important to know the type of processor your computer has and make sure that you install the right one. With this, it is also important that you know the type of operating system your computer is running. Most modern-day systems have 64-bit processors which provide better performance from many aspects. They provide better memory utilization, speedy functioning of the system. They also have greater memory utilization when compared to 32-bit processors. But in some cases, there will not be 64-bit drivers and that is when a 32-bit system can come to your rescue. It is the best option to buy a 64-bit operating system with 64-bit applications which help in providing the best performance.
This has been a guide to the top difference between 32-Bit vs 64-Bit operating system. Here we also discuss the 32-Bit vs 64-Bit operating system key differences with infographics and comparison table. You may also have a look at the following articles to learn more –
