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.
Is i686 32bit or 64bit?
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.
Can i686 run 64 bit?
You CAN run 64bit (=x86_64 in redhat and relatives, =amd64 in debian relatives) or 32bit (i386-i686) software (code, kernel, OS) on 64bit (AMD64,EM64T) enabled x86 compatible hardware (CPU). … You CAN NOT run 64bit software on 32bit hardware unless you use full HW virtualization (like qemu – not KVM).
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.
Is x86 32 or 64 bit?
x86 refers to a 32-bit CPU and operating system while x64 refers to a 64-bit CPU and operating system.

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.
How can I change 32 bit to 64 bit?
How to upgrade 32-bit to 64-bit on Windows 10

Can we install 64 bit OS on 32 bit processor?
You cannot install a 64 bit operating system on a 32 bit Processor. It is quite possible that the machine is both 32 and 64 bit, but the manufacturer put on the 32-bit system.
What is meant by 64 bit architecture?
In computer architecture, 64-bit integers, memory addresses, or other data units are those that are 64 bits (8 octets) wide. … From the software perspective, 64-bit computing means the use of machine code with 64-bit virtual memory addresses.
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.
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.)
Why is 32 bit called x86 and not x32?
The term “x86” came into being because the names of several successors to Intel’s 8086 processor end in “86”, including the 80186, 80286, 80386 and 80486 processors. Many additions and extensions have been added to the x86 instruction set over the years, almost consistently with full backward compatibility.
Is 86x same as 32 bit?
Windows Vista reports x86 for 32bit version and x86-64 for 64bit version. x86 is for 32 bit only. It is sometimes also referred to as x86- 32 .
Which is better x86 or x64?
The main difference between these two platforms is the amount of RAM they can access. x86 has a physical limit of 4GB RAM (although Windows reserves the top 1GB, limiting this further to a maximum of 3GB). x64 can access more than 4GB of RAM – up to more than you’ll ever need.
Is x86 better than x64?
X64 vs x86, which one is better? The x86 (32 bit processors) has a limited amount of maximum physical memory at 4 GB, while x64 (64 bit processors) can handle 8, 16 and some even 32GB physical memory. In addition, a 64 bit computer can work with both 32 bit programs and 64 bit programs.
