Difference between x86 and x64
Main difference
x86 and x64 are used for the Windows operating system. x86 refers to the 32-bit operating system, while x64 refers to the 64-bit operating system. x86 can only access 4 GB of RAM, while x64 can access 8 TB of RAM. The data information handling capacity is greater in x64 than in x86.
What is x86?
x86 is the 32-bit Windows operating system. Refers to the x86 family of microprocessors. Also called IA-32. x86 also refers to the set of instructions that are compiled to run in 32-bit mode. You can access the 4 GB of RAM.
What is x64?
x64 is the 64-bit Windows operating system. Also called Intel 64. x64 also refers to the set of instructions that are compiled to run in 64-bit mode of operation. You can access 8TB of RAM. Most laptops and PCs have x64 as it is the latest version. The data information capacity is comparatively high on x64. Since x64 is much more secure, there is no need to prevent data execution. x64 has twice as many general purpose registers and SIMD registers, so its usefulness is comparatively higher. Hardware periodic routines are switched to software, so it’s quite flexible.
