i386 vs i586

[Kyle D. Harris]

I guess i don't understand what the difference with these are. Does it matter if i download a i586 or i386 file? Thanks

Yes it does depending on the CPU you have.
i386 is compiled for Intel 80386 type of CPUs. This will work with everything released since then (including the various Pentium iterations, but excluding Itanium). Since it does restrict the available optimisations performance on newer CPUs is usually not as good as it could be. Enters i586. This does require a Pentium class CPU and will not work with earlier chips like the 80386 and 80486 variants. Therefore it does use Pentium specific optimisations and runs faster on these. On any reasonably modern system i586 should be fine
