    What is the difference between x86_64 and AMD64?x86_64 is name of specific 64-bit ISA. This instruction set was released in 1999 by AMD (Advanced Micro Devices). AMD later rebranded it to amd64. Other 64-bit ISA different from x86_64 is IA-64 (released by Intel in 1999). +1 Also CPU's have a Data bus and an Address bus - both are 64 bit in x86_64 (aka amd64).

    What is the difference between AMD64 and EM64T?EM64T supports microcode update as in 32-bit mode, whereas AMD64 processors use a different microcode update format and control MSRs. EM64T’s CPUID instruction is very vendor-specific, as is normal for x86-style processors. EM64T supports the MONITOR and MWAIT instructions, used by operating systems to better deal with Hyper-threading.

    What is the difference between arm and ARM64?The ARM architecture is typically used to build CPUs for a mobile device, ARM64 is simply an extension or evolution of the ARM architecture that supports 64-bit processing. Devices built on the ARM64 architecture include desktop PCs, mobile devices, and some IoT Core devices (Rasperry Pi 2, Raspberry Pi 3, and DragonBoard).

    What is AMD's 64-bit architecture?In 1999-2003, AMD extended this 32-bit architecture to 64 bits and referred to it as x86-64 in early documents and later as AMD64. Intel soon adopted AMD's architectural extensions under the name IA-32e which was later renamed EM64T and finally Intel 64.
