Difference between X86 and X64

Intel processors come in two types: X86 and X64. These processors have different instruction sets that affect how your computer runs. The main difference between the two is that X86 can only address up to 4GB of memory, while X64 can address up to 8TB. In most cases, you won’t need to worry about which processor your computer has, but if you’re interested in learning more, keep reading.

What is X86?

X86 is a family of processors that span several generations of computing. The earliest processors in the x86 family were used in desktop computers, and subsequent generations have been used in everything from servers to laptops. Today, x86 processors are some of the most popular processors on the market, and they are used in a wide variety of devices. One of the key features of x86 processors is their backward compatibility. This means that a processor from one generation can run software written for an earlier generation. This has made x86 processors very popular with both businesses and individual users. Another key feature of x86 processors is their modular design. This allows manufacturers to create different versions of the processor for different needs.

What is X64?

X64 is a 64-bit microprocessor architecture implemented by Intel and AMD. It is an extension of the x86 architecture, which is the most common instruction set used in 32-bit processors. The 64-bit extension allows for more addressable memory, meaning that more data can be stored in physical memory. This is especially beneficial for applications that require large amounts of data, such as video editing or 3D rendering. In addition, the extra registers and wider data paths of the x64 architecture allow for higher performance than its 32-bit counterpart. As a result, x64 has become the standard instruction set for new processors and is backward compatible with 32-bit software.

Difference between X86 and X64

The main difference between X86 and X64 is that the former is a 32-bit architecture while the latter is a 64-bit architecture. This means that X64 processors can handle twice as much data per clock cycle as X86 processors. As a result, they are more powerful and efficient than their 32-bit counterparts. In addition, X64 processors can address more memory than X86 processors, which is important for applications that require large amounts of data. Finally, X64 processors have more advanced features than X86 processors, such as support for virtualization and security features. As a result, they are typically found in high-end servers and workstations.


If you’re still unsure of the difference between X86 and X64, don’t worry. We’ve got your back. The main difference between these two types of processors is that X86 can only process 32-bit instructions while X64 can process both 32-bit and 64-bit instructions. This means that if you have an application that is designed to take advantage of 64-bit architecture, it will run faster on a system with an X64 processor than it would on a system with an X86 processor.
