Learn how future windows PC shifted toward 64-bits CPU architecture. Here the differences of Windows 32-bits vs Windows 64-bits explained in detail
Windows is the highest profile operating system installed world wide. Million users have this OS installed on their PC, laptop and gadget. Windows operating system offers many different types and versions according their functionality.
The latest common type of Windows run on 64-bit system replacing the old one 32-bit. Many software are also started to shift its compatibility to this sophisticated technology. So, it is a wise to get to know more about the 64-bits system.
So, what are the differences between this type of operating system?
What is Bit?
When you buy a new processor and find a sticker or mark says 64-bit it means your new CPU run on 64-bit base computing. The number refers to the size of data type that it handles. 64-bit CPU is capable of storing 264 number values such as memory addresses. 64-bit CPU is stronger in computing since it able to access four billion times compared to 32-bit.
The more bits CPU can handle the faster computing will be processed. The data process will be handled in larger chunk and accessing physical memory more efficient and accurate. This is why modern CPU is shifting toward 64-bits and starting to leave 32-bits system.
The differences between Windows 32-bits vs Windows 64-bits
1. The number of physical memory able to handle
The basic different is the maximum number of each type Windows physical memory (RAM) can be installed. 32-bits Windows maximum limit for RAM is less than 4GB while 64-bit Windows can be more than 4GB. It will be a waste to install more than 4GB on 32-bits Windows.
Lets take an example two same CPUs built on different base computing 32-bits and 64-bits, which one got faster performance? the answer is depend on what task they processed. For light task which is require less data to store on RAM, both 32-bits and 64-bits will show no difference in performance.
But when processing heavy task such as video rendering, playing modern game that requires storing data more in RAM, 64-bits will come as the winner since the process will be handle in more efficient way than 32-bit system. 64-bits able to access larger data from physical memory since it is not limited to 4GB RAM.
3. Software compatibility
Unfortunately the difference architectures of both system will affect in software compatibility. Here is why 32-bits Windows is not able to run 64-bits based software and not vise versa, 64 bit windows is able to run 32-bits software without problem.
Software developers today will likely shifting their app compatibility from 32-bits to 64-bits because of many benefits offered. If you still own 32-bits CPU, it is wise to upgrade to 64-bits system and update to Windows 64 version.
Wrapping up: Table list of the differences Windows 32-bits vs Windows 64-bits
|16-bits software compatibility||YES||NO|
|32-bits software compatibility||YES||YES|
|64-bits software compatibility||NO||YES|
|More than 4GB RAM||NO||YES|
|Reliable and efficient for light tasks||YES||YES|
|Reliable and efficient for heavy tasks||NO||YES|
|Old computer and driver compatibility||YES||NO|
|Suitable for graphic and video rendering||NO||YES|
