Difference Between 32 bit & 64 bit Operating Systems

Difference between x64 and x86

It usually refers to x86 for 32 bit OS and x64 for system with 64 bit.

Technically x86 simply refers to a family of processors and the instruction set they all use. It doesn’t actually say anything specific about data sizes. The term x86 started out as a 16-bit instruction set for 16-bit processors (the 8086 and 8088 processors), then was extended to a 32-bit instruction set for 32-bit processors (80386 and 80486), and now has been extended to a 64-bit instruction set for 64-bit processors. It used to be written as 80×86 to reflect the changing value in the middle of the chip model numbers, but somewhere along the line the 80 in the front was dropped, leaving just x86.

When 64 bit processors compatible with the x86 architecture were introduced, they were referred to as x86-64. x86-32 (and x86-16) were used for the 32 (and 16) bit versions. This was eventually shortened to x64 for 64 bit and x86 alone refers to a 32 bit processor. The 32 bit processors are designed to handle a limited amount of physical memory maximum of 4GB but 64 bit can handle high memory utilizing 8,16 and some even32 GB.

The 64 bit computers can run both 32bit programs and 64 bit programs. 32 bit computers cannot run 64 bit programs, because the bit sizes are fundamentally different. Latest Laptops with pre-installed Windows are usually x64 i.e. 64 Bit, old Desktops and Laptops could be having Windows x86 which means 32 bit.

How to determine if Windows OS is 32-bit (x86) or 64-bit (x64)

Open the Power User menu. Press the Windows key + X to open this menu. Click on System.

There is ne another way you can understand that if your PC is running 64-bit Windows, you’ll probably find a Program Files (x86) folder on your hard drive. This stores 32-bit applications, while the other ‘Program Files’ folder contains all the 64-bit apps you’ve installed.

Which is better Windows 7 x86 or x64?

They are essentially exactly the same.

All x86 programs will run on x64 version.

If you have 4GB or more of RAM, you need x64.

x86 will not be able to address more than 3.5GB of RAM.

I have 8GB, so I have Win7 x64.

If you have RAM >4GB and a processor with x64 architecture (most processors in the past few years do), you should go for Windows 7 x64. By personal experience, I can say that incompatibility is hardly an issue, as programs which do not run on x86 architecture get installed separately and run smoothly with no trouble whatsoever. However, you may find certain incompatible software especially DOS programs.

Windows 7 x64 is better in all aspects. It runs all x86 programs and was designed to do so. Getting x86 is pointless. If you get x64 then you have the option of upgrading your RAM at a later date. With x86 you can only upgrade to a little over 3 gigs. With x64 you can upgrade much further. x86 will just inhibit your upgrade potential.

So far for me x64 is better (system below) for a couple of reasons. First off, it’s running my printer without me trying to find non-existent 64 bit drivers (I never got my printer working with Vista Ultimate x64). The only software that didn’t install for me was freeware that I didn’t really need. I still have avast! and a few freeware malware scanning programs. The 64-bit programs that I have installed on 7 RC x64 start up faster and seem to run more smoothly (AutoCAD and a few others). I’m not sure if this is specific to 7 x64, but my DVD burner has been acting up (in XP Pro) and I thought it was dying, but I’ve been able to burn a dozen or so DVDs with no problem (without installing Nero to get the drivers installed). Also, my hard drives are working at SATA II which they were not with RC x86.

Windows 7 x64 is compatible with almost all 32-bit applications so I prefer it. This is my system:

AMD Phenom II X4 940

MSI K9A2 Platinum motherboard

8GB OCZ Reapher HTC PC6400

See, with an x64 system, I can access all of my RAM and therefore use the power of the Phenom II X4 940 more efficiently.

What Is the Difference Between 32 Bit and 64 Bit (x86 vs x64) [Partition Manager]

Summary :

Windows is a widely used operating system in the world. However, there are still a great number of users are confused about x86 vs x64. You may also wonder what difference between 32 bit and 64 bit. Now, MiniTool will explore the answers together with you.

Quick Navigation :

What Does x86 and x64 Mean?

In order to figure out what is the difference between 32 bit and 64 bit, you need to know what does x86 and x64 refer to. Initially, they refer to the type of your CPU and operating system on which Cantabile will run.

According to the technical term, x86 refers to a family of instructions ending in 86. It is one of the most successful processor’s line of Intel. In order to reflect the changing value in the middle of the chip model numbers, x86 used to be written as 80×86. Until now, it is written as x86 after dropping line 80.

In fact, when compatible with the x86 architecture, 64-bit processors were referred to as x86-64 or x86-32 that was used for the 32 (and 16) bit versions. However, 64-bit processors were eventually shortened to x64 and 32 bit was shortened to x86.

Now, term x86 refers to a 32 bit CPU and operating system for 32-bit processors (80386 and 80486), while term x64 refers to 64 bit CPU and operating system for 64-bit processors. So, what is the major difference between 32 and 64 bit? Let’s keep reading the following section “x86 vs x64” to get the answer.

You may notice that they are two program files folders on your Windows PC. What’s their difference? This article will show you the more detailed information.

What Is the Difference Between 32 bit and 64 bit (x86 vs x64)

The biggest difference between 32 bit and 64 bit is that they can access different amount of RAM. X64 vs x86, which one is better? The x86 (32 bit processors) has a limited amount of maximum physical memory at 4 GB, while x64 (64 bit processors) can handle 8, 16 and some even 32GB physical memory.

In addition, a 64 bit computer can work with both 32 bit programs and 64 bit programs. However, a 32 bit computer can only run 32 bit programs. This is because their bit sizes are different from the basic level. Those laptops that have pre-installed Windows are usually x64. On the contrary, the older computers could be Windows x86.

In most cases, 64 bit processors work more efficiently than a 32 bit processor when dealing with data in great chunks. If you are using a 64-bit Windows PC, you can find a folder named Program Files (x86) on the C drive. The folder stores 32-bit applications, while all the 64-bit apps that you have installed are stored in Program Files folder.

Here comes to a question – how to check if your windows OC is 32 bit or 64 bit (x84 or x64)?

What is x86 Architecture and its difference between x64?

Have you ever come across x86 and x64 but do not know what they mean? No worries, as this blog will cover everything you need to know about x86 and its architecture together with x64 and their differences between each other.

What is x86 Architecture?

x86 is a family of instruction set architectures (ISA) for computer processors initially developed by Intel. They refer to the way a computer processor (CPU) handles information.

What is an instruction set architecture?

It is an abstract model of a computer that is also referred to as computer architecture. It is part of a computer that pertains to programming which specifies the behaviour of machine code. The instruction set is the language that a computer’s brain is designed to understand which provides commands to the computer processor and tells it what to do.

Back to the x86…

The x86 is developed based on the Intel 8086 microprocessor and its 8088 variant where it started out as a 16-bit instruction set for 16-bit processors where many additions and extensions have been added to the x86 where it grew to 32-bit instruction sets over the years with almost entirely full backward compatibility.

The bit in both 32-bit and 16-bit is shorthand for a number. For example, for 32-bit, the number will contain 32 bits which are binary digits that are either 0 or 1. For a 32-bit number, it will look like something like this 10101010101010101010101010101010.

Today, the term x86 is used generally to refer to any 32-bit processor compatible with the x86 instruction set. x86 microprocessor is capable of running almost any type of computer from laptops, servers, desktops, notebooks to supercomputers.

What is x64?

Similar to the x86, the x64 is also a family of instruction set architectures (ISA) for computer processors. However, x64 refers to a 64-bit CPU and operating system instead of the 32-bit system which the x86 stands for.

But why does x64 refers to a 64-bit system while x86 refers to a 32-bit system?

That was the question I asked myself too at first. However, this is because as when the processor was first being created, it was called 8086. The 8086 was well designed and popular which can understand 16-bit machine language at first. It was later improved and expanded the size of 8086 instructions to a 32-bit machine language. As they improve the architecture, they kept 86 at the end of the model number, the 8086. This line of processors was then known as the x86 architecture.

On the other hand, x64 is the architecture name for the extension to the x86 instruction set that enables 64-bit code. When it was initially developed, it was named as x86-64. However, people thought that the name was too length where it was later shortened to the current x64.

What is the difference between x86 and x64?

As you guys can already tell, the obvious difference will be the amount of bit of each operating system. x86 refers to a 32-bit CPU and operating system while x64 refers to a 64-bit CPU and operating system.

Does having more amount of bits in each operating system have any benefits?

Of course! This is one of the main reason the number of bits keeps increasing over the years from 16-bits to 64-bits currently. As mentioned above, the bits are shorthand for a number which can only be 1 or 0. This causes the 32-bit CPUs not being able to use a lot of RAM as 1 and 0, the total number of combinations is only 2^32 which equals to 4,294,967,295. This means the 32-bit processor has 4.29 billion memory locations each storing one byte of data which equates to approx. 4GB of memory which the 32-bit processor can access without workarounds in software to address more.

Today, 4GB is enough for basic tasks but if you wish to run multiple programs and other more heavy load tasks, 4GB is not sufficient. In addition, with a 64-bit system, it will be more efficient as it can process data in 64-bit chunks compared to 32-bit chunks. Your 64-bit system can also run 32-bit programs as they are backwards compatible. But, it doesn’t work the other way where a 32-bit computer cannot run 64-bit programs.
