X86 vs. X64: Know the Difference
By Shumaila Saeed || Published on February 7, 2024
X86 refers to a 32-bit instruction set architecture for CPUs, while X64, also known as x86-64, is a 64-bit extension of the x86 architecture.
Key Differences
X86, originally based on the Intel 8086 microprocessor, is a 32-bit architecture widely used in computers for decades. X64, also called AMD64 or Intel 64, enhances the x86 architecture to 64-bit, allowing for more complex and powerful computing tasks.

X86 systems can address up to 4GB of RAM directly, which was sufficient for computing needs in the past. X64 systems can address a much larger memory space, exceeding 4GB, making them suitable for modern applications that require more memory.
