Processor architecture

Processor architecture

1. x86

   • A 32-bit architecture that processes multiple instructions using a 32-bit address space.
   • An x86 processor uses fewer registers than an x64 processor.
   • Registers are storage areas used by the CPU when performing calculations.
   • An x86 processor can support a 32-bit operating system.

2. x64

   • This 64-bit architecture adds additional registers specifically for instructions that use a 64-bit address space.
   • The additional registers allow the CPU to process instructions much faster than x86.
   • The x64 processor is backward compatible with the x86 processor.
   • An x64 processor can support 32-bit and 64-bit operating systems.
