Download/Browse Funtoo Linux Subarches
This page provides an overview of Funtoo Linux sub-architectures (also called subarches) designed for quick and easy reference. Funtoo Linux provides optimized installation images for all sub-architectures listed below. Clicking on a particular subarch will bring you to a detail page where you can learn more about that subarch and download a stage3 for installation.

How to Identify your CPU
There are a couple of ways to identify the type of CPU you have. One option is to use the lscpu command:
root # lscpu
If the lscpu command is unavailable, you can get similar information via /proc:
root # cat /proc/cpuinfo | grep "^model name" | uniq model name : Intel(R) Core(TM) i7-2640M CPU @ 2.80GHz
The cpuid command is another option and can provide other interesting information:
root # emerge cpuid; cpuid | tail -n 1
Search is your friend. Take the chip name gathered, then google wiki chipname to find the wikipedia article for your chip. The right hand column of your processors wiki article will list the microarchitecture.
example: searching for "amd phenom wiki" returns this article & the article says its "Microarchitecture K10"
