Difference between 32 and 64 bit architecture, Which one you should choose?

The tendency of a computer’s processor to deal with information on RAM (random access memory) depends upon 32 bit and 64 bit version of Windows. 64 bit version can handle more RAM and apps than 32 bit.

Let’s understand it in a simple way. 64 bit version can deal with physical memory (RAM) above 4 GB and up to 128GB (yes, it exists!) while 32-bit version can address RAM up to 4 GB only. Therefore, if you have a 32 bit version of Windows installed on your computer then installing RAM above 4 GB doesn’t make sense.

The ability to handle large memory makes the 64 bit version more efficient while dealing with processes. Hence, it increases the overall performance of your PC. So 64 bit is more powerful in a nutshell. Now lets check some more things related to these two technologies.

32-bit or 64-bit, What to choose and Why?
Difference between 32 and 64 bit architecture, Which one you should choose?

Advantages of 64 bit computer
  • The main advantage of using 64-bit version of Windows is that it offers better memory accessibility and management.
  • Enhanced security features like Kernel p@tch Protection, support for hardware-backed data execution protection, mandatory driver signing, removal of support for 32-bit drivers and removal of the 16-bit subsystem available.
  • Performance of those programs that are specially written for 64 bit operating system is great.
Disadvantages of 64 bit computer
There is no specific disadvantage of using this version but there are some things you have to take care of before deciding to use it.
  • You should check availability of device drivers because 32 bit device drivers do not work on 64 bit version.
  • Most of the hardware devices are not compatible with 64-bit computer.
  • Device drivers must be digitally signed by the developer.
  • Some programs of 32 bit aren’t compatible with 64 bit.
How to Choose a correct version of Windows

64 bit version
  • Selecting correct version of Windows depends upon your priority and need. If you want to take advantage of large memory (more than 4 GB) then you could go for 64-bit version. But do check for the 64-bit versions of various tools and programs you use everyday before making the switch.
  • Most of new software and hardware are supported by 64-bit version. Check compatibility status of your software and devices.
32 bit version
  • 32 bit versions are cheaper than 64 bit versions.
  • If you are using old software and hardware then you could go with 32-bit version because it can support all your program and devices.
Note: Most programs designed for 32 bit version can support 64-bit version too (except some antivirus programs). But if a program is designed for 64 bit version then it won’t work on 32 bit version.
