The i686 vs i586 difference is cmov. Is dropping hardware worth this instruction? I suggested some benchmarking and demonstrated that it's a very small improvement for Theora. I'm not sure if anyone got around to testing freetype, firefox, or any of the other couple CPU heavy desktop apps. It would probably be most interesting to perform that test on the x86-only ATOM, since I can see CMOV being a bigger win on an in-order CPU. (I can't personally protest: I think all the x86 stuff I have has CMOV). -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
