x86-64 (also called x86_64, x64, or amd64) is the 64-bit CPU architecture that is used in Intel and AMD processors. It is an extension to the 32-bit x86 (i386) architecture. The x86-64 architecture is used in most CPUs for home computers and servers in use today. It is incompatible with the ARM64 architecture, which is in use in smartphones ...
Jan 1, 2024 · x86 Architecture. The x86 architecture has 8 General-Purpose Registers (GPR), 6 Segment Registers, 1 Flags Register and an Instruction Pointer. 64-bit x86 has additional registers. Wikipedia has related information at Processor register.
A 64-bit processor refers to a microprocessor that can process data and instructions in chunks of 64 bits. Microprocessors that can handle 64 bits perform a larger number of calculations per second compared to 32-bit processors. Typical variations of the term include 64-bit CPU, 64-bit computing and 64-bit microprocessor.
