There are two parts to this. The first is that all Fedora RPMs are compiled to x86-64-v1. The second part is that there are programs packaged by Fedora that detect the micro-architecture and run optimised code paths depending on what is detected. You can see what your micro-architecure support is with this command: /usr/lib64/ld-linux-x86-64.so.2 --help Which for my main desktop system reports at the end: This program interpreter self-identifies as: /lib64/ld-linux-x86-64.so.2 Shared library search path: (libraries located via /etc/ld.so.cache) /lib64 (system search path) /usr/lib64 (system search path) Subdirectories of glibc-hwcaps directories, in priority order: x86-64-v4 x86-64-v3 (supported, searched) x86-64-v2 (supported, searched) You can see from this that there is support for searching for micro-architectures specific code. Depending on the software that you care about this may or may not be doing this. For most packages compiling to x86-64-v4 make little or no performance difference. At the moment there is no plan to rebase Fedora on x86-64-v2 let alone x86-64-v4.
