Difference Between 32-bit and 64-bit Processor

We always look for better configuration whenever we purchase computer or laptop for our personal use; there are so many things we have to make sure while buying a computer like RAM size, CPU, the storage capacity of hard disk and processor as well. We always want to have latest specifications and better processors; if you’re using windows on your computer then probably you have noticed that in your windows you have two program files folders in which one is “Program files” and the other one “Program Files (x86)”.Mainly to store the DLL files of 64-bit applications the folder “Program Files” is used and to store DLL file of 32-bit applications the folder “Program Files (x86)” is used which is one of the major differences you can notice while having 32-bit or 64-bit processor assembled in your system. We hardly pay our attention towards this little piece of information but when it comes to performance and efficiency then these little things makes much difference.

What is the 32-bit processor?

We all have been using a 32-bit processor which is known as the primary processor in all our computers, every single processor manufactured by Intel and AMD in early stages were 32-bit. All the operating systems and different software used in 32-bit processors mainly work with data units that are 32 bits wide. Some of the most common operating systems like Windows 95, 98, 2000 and XP are 32-bit operating systems. The computers which have 32-bit processors cannot use 64-bit operating systems; you can install only 32-bit operating systems on that PC.

What is the 64-bit processor?

The first 64-bit computer was manufactured by IBM and its name was IBM 7030 stretch supercomputer, but only in the early 2000s, we have started using 64-bit processors. Even Microsoft has introduced a 64-bit version of Windows XP which is compatible to use with 64-bit processors only after the 2000s. Other popular operating systems also capable of working with 64-bit processors are Windows Vista, Windows 7 and Windows 8, which mainly works with data units that are 64 bits wide. You can even install the 32-bit operating system on a computer which has a 64-bit processor, but it will not work with its full capacity when you don’t install the 64-bit operating system on a computer which has a 64-bit processor.

The main difference between 32 & 64-bit processors

The biggest difference between 32-bit and 64-bit processors is the speed with which they can perform calculations, 64-bit processors work on much faster speed as compared to 32-bit processors. Even 64-bit processors come in dual core, quad core, six core and eight core variants which are mainly used in computers manufactured for home use. With multiple core processors, you can expect an increased number of calculations per second and also much faster-processing speed, which makes your computer runs at a faster speed. Today, we use programs that require faster calculations and processing which we will get only from 64-bit processors.

Even 64-bit processors support more RAM than 32-bit processors, at one end 32-bit processors support only 3-4GB of RAM whereas 64-bit Processors are designed to support 4GB RAM or above as well. So if you need to run applications that require more RAM like graphic design, video editing and engineering programs you need to have 64-bit processors installed in your desktop before installing this high-performance software. But in case if you need to run high graphics game you don’t have to upgrade your processor as you need to have a high graphics card instead of the better processor.


At present we all are using 64-bit processors as almost all computer manufacturers are installing 64-bit processors in their PCs, 64-bit processors are cheap as well and deliver better performance, so it is more profitable to buy 64-bit processor instead of 32-bit processor and soon every computer retailers offer only 64-bit processors in upcoming time. So we finally conclude that 64-bit processors are much better than 32-bit processors and with 64-bit processors, you can expect better performance with multiple layers in it. If we simply calculate the working speed of 64-bit processor than 64-bit processors can access over four billion times the physical memory of 32-bit processors which is a huge difference.
