What does x64 mean?
x64 is short for 64-bit processor architecture. It is often contrasted with the x86 architecture, which refers to 32-bit Intel processors, including the 386, 486, and 586 series. However, x64 refers to all 64-bit processors, regardless of manufacturer. The “x86-64” tag specifies a 64-bit x86 processor.

Why is 32 bit called x86?
The nickname x86 comes from the 32-bit instruction set. So all x86 processors (without a main 80) execute the same 32-bit instruction set (and thus are all compatible). So x86 has become a de facto name for that set (and thus 32-bit). AMD’s original 64-bit extension to the x86 set was called AMD64.
What is x64 vs arm64?
x86_64 is the architecture for Intel’s 64-bit CPUs, sometimes also referred to simply as x64. It is the architecture for all Intel Macs shipped between 2005 and 2021. arm64 is the architecture used by newer Apple Silicon-based Macs, shipped in late 2020 and beyond.
What is the difference between IA64, x86 and x64?
IA64 stands for the Itanium 64 architecture, while x64 refers to the 64-bit extension that can be found on the x86 architecture. One of the main differences between the two is that IA64 is only available to Intel users, while x64 can be used by non-Intel users as well.
What is the difference between x64 and IA-64?
IA64 refers to the 64-bit Itanium architecture, while x64 is the 64-bit extension of the x86 architecture. IA64 is exclusive to Intel, while x64 is used by everyone. IA64 was intended for high-end server applications, while x64 was initially intended for desktops but was expanded.
What does x86 or x64 mean?
In short, “x86” and “x64” mean 32-bit and 64-bit respectively. While 64-bit compatible systems are often more powerful, since programs running on them have access to much more memory, installing a 64-bit operating system isn’t as important.
How to determine if Windows is x64 or x86?
Right-click Start, and then click Explore.
What is arm64 v8a?
arm64-v8a. This ABI is for ARMv8-A based CPUs, which support the 64-bit AArch64 architecture. Includes Advanced SIMD (Neon) architecture extensions. You can use Neon intrinsics in C and C++ code to take advantage of the advanced SIMD extension. Arm also offers some portability tips on 64-bit Android development.
