What is am64?
AMD64 is a 64-bit processor architecture that was developed by Advanced Micro Devices (AMD) to add 64-bit computing capabilities to the x86 architecture. It is famous for its ability to support simultaneous 32-bit and 64-bit computing without performance penalties.
Is ARM64 same as AMD64?
ARM64, also known as ARMv8-A, is the 64-bit version of the advanced risc machine (ARM) architecture primarily designed for smartphones and interconnected devices. AMD64 is the 64-bit extension of the popular x86 architecture which was originally developed by Intel.
How do I know if I have x64?
Go to Windows Explorer, right click on This PC and then select Properties. You’ll see the system information on the next screen. In here, you should look for System Type. As you can see in the image above, it says “64-bit Operating System, x64-based processor”.
Is x64 the best?
Simply put, a 64-bit processor is more capable than a 32-bit processor because it can handle more data at once. A 64-bit processor can store more computational values, including memory addresses, which means it can access over 4 billion times the physical memory of a 32-bit processor. That’s just as big as it sounds.

Does Visual Studio run on a 64-bit computer?
However, you probably have a 64-bit computer. When Visual Studio is installed on a 64-bit Windows operating system, additional developer command prompt shortcuts for the 64-bit, x64-hosted native and cross compilers are available.
Does /favor:Intel64 cause performance issues on AMD processors?
Code that is generated with /favor:INTEL64 might cause worse performance on AMD Opteron, and Athlon processors that support 64-bit extensions. Intel64 architecture was previously known as Extended Memory 64 Technology, and the corresponding compiler option was /favor:EM64T.
What compiler does Visual Studio use to build ARM code?
When you install a C++ workload in the Visual Studio installer, it always installs 32-bit, x86-hosted, native and cross compiler tools to build x86 and x64 code. If you include the Universal Windows Platform workload, it also installs x86-hosted cross compiler tools to build ARM code.
