Advantages of 64 bit OS Over 32 bit OS

advantages of 64 bit OS Over 32 bit OS
|Updated on: December 3, 2020

Did you buy a new computer recently? You might have a noticed a sticker saying 64-bit operating system(OS). You might have noticed that installer files are available in 32 bit and 64 bit or might have seen a note that software supports only 64-bit operating system.

So, what is all about 32 and 64 bit operating system? Is 64 bit operating system better than 32-bit operating system? Let’s understand.

The bits of operating system and processor tells you the amount of information which can be processed by your CPU whenever it operates. The more data that can be processed at any one time, the faster the system can perform. In simple words, more the number of calculations per second that can be performed, can increase the processing power, and help your computer to run faster

Now, applying this logic, the major difference between 32-bit processors and 64-bit processors is the number of calculations per second they can perform, which affects the speed at which they can complete tasks.

64 bit operating system is not something new. All the systems of today use 64 bit processor and that has been the norm since 2003.  Choosing a 64 bit system gives you:

  • Better software performance
  • Increased memory support
  • Better computer performance
  • Enhanced Security features
  • The pride of using the latest and the most advanced technology

Let’s understand of some these in detailed.

Advantages of 64 bit operating system over 32 bit operating system

Addressable memory

32-bit operating systems can address a maximum of 4 GB of RAM. In another way, even if your computer has more than 4 GB RAM, let’ say 8 GB, a 32-bit system can only access up to 4GB. Rest is inaccessible.

On the other hand, 64 bit operating system can address up to 17,179,869,184 GB(16 exabytes). That’s a lot more than 4GB of memory that a 32 bit operating system can handle.

In simple words, a 64 bit computer with a 64 bit processor can access more than 4 GB of RAM. If a computer has 8 GB of RAM, 64-bit compute can make full use of available resource.

Key benefit to the user

The 64 bit operating system can make full use of available system resources as compared to 32 bit system. To simplify, 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.

Computer Performance

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.

Key benefit to the user

You can multi-task, switch between various application etc. seamlessly without hanging issues that you may encounter in 32 bit operating system.

Software performance

Today, more number software’s are written to fully leverage the benefit of 64 bit operating system. If you are using 64 bit operating system and install software of 64 bit, you can up-front notice the increase in performance. This becomes even more critical when you are performing a huge operation that requires system to access more memory.

Key benefit to the user

Increase in software performance leads results in an increase in overall efficiency.
