Dear fellow testers,
I am sorry to ask, but I read about the changes on i686 moving to i586
and the i386 packages to i586. I had known prior to this that
i686 ---> Pentium computer PIII, PIV, Intel based CPU i586 ---> AMD athlon, other AMD capable computer x86_64 ---> AMD 64 capable CPU or similar processor
The default 32-bit x86 target in koji would be changed from i386 to i586 http://fedoraproject.org/wiki/Features/ArchitectureSupport
I assume this is only temporary as after this release it will go back to
i686 right?
The other distributions I am familiar with that used i586 packages are
OpenSUSE and Mandriva namely. This only makes me confused as the i586 packages are optimized for AMD processors and the i686 packages for Intel based CPU's like Pentium III/IV.
I am only a bit confused with this and if someone can help me undestand
better I would appreciate it very much :)
ix68 has nothing to do with the cpu vendor (AMD, INTEL, VIA) it just means the minimum required instruction set that is needed for the software to run. i586 means "Pentium or older"
i686 is pentium pro and later (or compatible), i586-only is refered to all other pentium (or compatible), and i386-only is all intel compatible starting with i386 and lower than pentium. see also http://en.wikipedia.org/wiki/I686
however it may be interesting to hear what fedora package builders have to say on this matter.
