i386 refers to the 32-bit edition and amd64 (or x86_64) refers to the 64-bit edition for Intel and AMD processors. Wikipedia’s i386 entry: The Intel 80386, also known as the i386, or just 386, was a 32-bit microprocessor introduced by Intel in 1985… … x86-64 is an extension of the x86 instruction set.
Is i386 the same as x86?
This is termed x86, IA-32, or the i386-architecture, depending on context. 80386/i386 was the first 32-bit Intel processor. … But the i386 stuck around as a label and is used as an alias to x86 (just like amd is used as an alias to x64 architecture, even though there are Intel x64 processors as well).
Do I have AMD64 or i386 Linux?
To know whether your system is 32-bit or 64-bit, type the command “uname -m” and press “Enter”. This displays only the machine hardware name. It shows if your system is running 32-bit (i686 or i386) or 64-bit(x86_64).
What is i386 and i686?
i386 is for extremely old CPU generation dating before Pentium. i686 is post Pentium generation. … That being said, i386 marks a ‘compatibility’ build and should work on ANY 32bit x86 CPU. i686 may or may not use MMX, SSE and more extensions.
What is i686 in Linux?
i686 means that you’re using 32 bit OS. … i686 code is intended to be executed on processors which are compatible with the 32 bit Intel x86 platform, which includes all Intel 32bit x86 processors up to and including the Pentium 4, etc. as well as processors from AMD and other vendors which make compatible 32bit chips.
What is x86_64 in Linux?
Linux x86_64 (64-bit) is a Unix-like and mostly POSIX-compliant computer operating system (OS) assembled under the model of free and open-source software development and distribution. Using host OS (Mac OS X or Linux 64-bit) you can build native application for Linux x86_64 platform. Linux x86_64.
Is Ubuntu a AMD64?
Ubuntu is currently among the most popular of all GNU/Linux distributions. Since the release the AMD64 architecture, many Linux users have debated whether or not it is worth going to a 64-bit version of their operating system if they have a capable processor.
How do you find out which distribution of Linux is running?

It has amd64 stated as architecture so you can use amd64 on this. Show activity on this post. To find information about your CPU including architecture, execute lscpu in terminal. For Intel systems, the Vendor ID is – GenuineIntel and for AMD – AuthenticAMD .
What is armv71?
armv7l is 32 bit processor. … ARMv8-A introduces 64-bit architecture support to the ARM architecture and includes: 64-bit general purpose registers, SP (stack pointer) and PC (program counter) 64-bit data processing and extended virtual addressing.
What is difference between amd64 and i386?
The difference between amd64 and i386 is that amd64 is 64-bit while i386 is 32-bit. This is the width (in bits) of registers available in the core. … Well written code for a 32-bit system should compile and run on a 64-bit system but not all code is well written.
Is AMD a x64?
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 sometimes referred to as x86-64, x64, and Intel 64.
Why is it called amd64?
The 64-bit version is typically called ‘amd64’ because AMD developed the 64-bit instruction extensions. (AMD extended the x86 architecture to 64 bits while Intel was working on Itanium, but Intel later adopted those same instructions.)

Is x86 a 32-bit?
32-bit is NOT called x86. There are tens of 32-bit architectures such as MIPS, ARM, PowerPC, SPARC which are not called x86 . x86 is a term meaning any instruction set which derived from the instruction set of Intel 8086 processor. … 80386 was a 32-bit processor, with a new 32-bit operating mode.
What is difference between i686 and x86_64?
Technically, i686 is actually a 32-bit instruction set (part of the x86 family line), while x86_64 is a 64-bit instruction set (also referred to as amd64). From the sound of it, you have a 64-bit machine that has 32-bit libraries for backwards compatibility.
