What is the difference between windows x64 and x86

The difference between windows x64 and x86 is: 1. Different CPU processing capabilities, x86 can process 4 bytes at a time, while x64 can process 8 bytes; 2. Different memory configurations, x86 can support up to 4G , while x64 can support up to 16T; 3. Compatibility differences, x86 cannot run 64-bit programs, while 64-bit systems can run 32-bit programs; 4. Different hardware requirements, x86 hardware requirements are relatively low, while x64 hardware requirements are higher .

The operating environment of this tutorial: Windows 10 system, DELL G3 computer.

Then the 64-bit system processes 2 to the 64th power of bytes, while the 32-bit system processes 2 to the 32nd power of bytes, just like making money. I can earn 2 to the power of 64 (184 trillion billion) in one second, but you can only earn 2 to the power of 32 (4.3 billion) in one second. You can imagine how little the processing power of a 32-bit system is compared to a 64-bit system.

Different memory configurations

32-bit can support up to 4G, while 64-bit can support up to 16T. The latter may reflect higher device configuration performance. This means that if your computer is a 32-bit system, there will be no difference between running 4G memory and 8G memory, which will cause a waste of resources.

Compatibility difference

Regarding software compatibility issues, 32-bit systems cannot run 64-bit programs, but 64-bit systems can run 32-bit programs. Typically, 32-bit systems install 32-bit software, while 64-bit systems install 64-bit software.

Different hardware requirements

The hardware requirements of 32-bit systems are relatively low, while the hardware requirements of 64-bit systems are higher. In other words, a 64-bit operating system can only be installed on a 64-bit configured computer, while a 32-bit system can be installed on a 32-bit (32-bit CPU) or 64-bit (64-bit CPU) computer.

How do you know whether your computer is 64-bit or 32-bit?

Just right-click My Computer (This Computer) and select [Properties] , find the system type column in the interface that appears, and you can see the computer’s operating system number
