What is i686 architecture in Linux?

When you’re installing Linux, you may be offered a choice between i686 and x86_64. In general terms, I686 is the 32-bit version while x86_64 is the 64-bit version of the OS. The 64-bit version is better for memory-intensive processes, but the 32-bit version is acceptable for most uses.

Can we install i686 package on x86_64?

These 64-bit processors are fully backward compatible with their 32-bit predecessors, so if you have a AMD64 or Intel 64 processor, it’s up to you whether to install the 64-bit x86_64 packages or the 32-bit i686 packages.

Is my computer i686 or x86_64?

i686 is the 32-bit version, and x86_64 is the 64-bit version of the OS. The 64-bit version will scale with memory better, particularly for workloads like large databases which need to use lots of ram in the same process.

Is i386 the same as i686?

i386 is for extremely old CPU generation dating before Pentium. i686 is post Pentium generation. No one today have i386, they are at least 15 years old. That being said, i386 marks a ‘compatibility’ build and should work on ANY 32bit x86 CPU.

What is i686 w64?

Mingw-w64 is a free and open source software development environment to create Microsoft Windows PE applications. It was forked in 2005–2010 from MinGW (Minimalist GNU for Windows). Mingw-w64 can generate 32 bit and 64-bit executables for x86 under the target names i686-w64-mingw32 and x86_64-w64-mingw32 .

How do I get 32-bit Linux libraries?

To install 32-bit libraries on Ubuntu 13.04 (64-bit) or later, open Terminal and type: sudo apt-get install lib32z1 (you will need to enter your password). Then just for good measure, let’s make sure your Ubuntu is up to date. Type sudo apt-get update and lastly, restart your computer.

What is the difference between arm64 and x86_64?

ARM and x86 are for 32-bit processors, while arm64 and x86_64 are for 64-bit processors.

Is my computer i686?

On the Linux operating system, access the command line interface and enter the following command. Look for “lm” in the command output. If lm is found in the output, then the CPU is 64-bit. If you don’t see lm or see i386, i486, i586, or i686 in the output, then the CPU is 32-bit.

What is ISO i686?

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.

Can I install i386 on i686?

i386: The 80386 CPU has historically been the bare minimum for running Linux on a PC-compatible system. An “i686” package is designed to run on these systems (and will usually perform better than a “i386” version); an “i686” system can run any i386, i486, i586, or i686 package.

What is i686 PAE architecture?

i686 is the Intel P6 microarchitecture from the late 1990’s. It is 32-bit. PAE is Physical Address Extension and that allows a 32-bit CPU to access more that 4 GB of address space. So on 32-bit x86 CPUs you can use the NX (No eXecute) bit in the page tables and address up to 64 GB of memory.
