Hi code releaser,
Why is the x64 tsvn downloads just labeled as AMD64 Architecture?
Surely this can be confusing to Joe public. Wouldn't x86-64 be more
palatable and seem less CPU vendor specific? or maybe add a asterisk
next to it and an explanation of the newer named AMD64 standard on the
bottom of the downloads page?
Microsoft uses x64 (or x86-64) to refer to CPUs can natively run
programs that run on x86 processors from Intel, Advanced Micro Devices
(AMD), and other vendors.
The generic term x86 refers to the instruction set of the most
commercially successful CPU architecture in the history of personal
computing.[1] It is used in processors from Intel, AMD, VIA, and
others, and derived from the model numbers of the first few
generations of processors, backward compatible with Intel's original
16-bit 8086 CPU, most of which were ending in 86.[2] Since then, many
additions and extensions have been added to the x86 instruction set,
almost consistently with full backwards compatibility.
x86-64 is a 64-bit superset of the x86 instruction set architecture.
Because the x86-64 instruction set is a uperset of the x86 instruction
set, all instructions in the x86 instruction set can be executed by
central processing units (CPUs) that implement the x86-64 instruction
set; therefore these CPUs can natively run programs that run on x86
processors from Intel, Advanced Micro Devices (AMD), and other
vendors.
x86-64 was designed by AMD, who have since renamed it AMD64. It has
been cloned by Intel under the name Intel 64 (formerly known as EM64T
among other names).[1] This leads to the common use of the names
x86-64 or x64 as more vendor-neutral terms to collectively refer to
the two nearly identical implementations.
x86-64 should not be confused with the Intel Itanium architecture,
also known as IA-64, which is not compatible on the native instruction
set level with the x86 or x86-64 architecture.
Regards,
Pierre
