Editors: While this information is available in other places, such as Wikipedia, it often takes some time to study and cross-reference the various articles to get a good understanding of each type of sub-architecture, and this information generally isn't all collected neatly in one place. When possible, links to more detailed Wikipedia pages are provided. You are encouraged to help maintain this page as well as the Wikipedia articles referenced here.

i know that my system's k10, but how do we figure something out that lines up 1-1 that this subarch is definitely your sub arch? Threesixes (talk) 21:49, February 4, 2015 (UTC)
How do we edit those Descriptions? Would like to make it more clear what they mean to the average user. -grouche
Intel doesn't always support the same extensions for all CPU's within the same subarch. For example Westmere Pentium doesn't support SSE4.1, SSE4.2 and POPCNT. The solution is to query your CPU for supported extensions by booting into linux, note supported flags from "cat /proc/cpuinfo" Choose a stage 3 compiled with march that only has extensions supported by your CPU flags. https://gcc.gnu.org/onlinedocs/gcc/x86-Options.html
