Hi there, I don’t normally intrude on the developers list, but I’ve seen something I believe to be factually wrong, and don’t want Fedora to make a decision based on it:

This is right for Intel processors, but AMD processors introduced these extensions later. http://www.amd.com/us/products/technologies/amd-64/Pages/amd-64.aspx says (about AMD processors): “SSE instructions were brought on board with the AMD Athlon XP processor” and “the AMD Athlon 64 and AMD Opteron™ processors offer strong performance, thanks to the addition of SSE2 support” This means that there are non-SSE i686 processors with speeds of up to 1400 MHz, and non-SSE2 processors with speeds of 2.2 GHz. Thanks for your attention, James. -- E-mail: james@ | [Computer] chips consume power, and in return they give aprilcottage.co.uk | you heat and a few electrons in the right places. or James.Wilkinson | Occasionally they also give you a flash of light and @sparex.co.uk | smoke as well, but few chips do that twice. | -- Charlie Demerjian, The Inquirer -- fedora-devel-list mailing list fedora-devel-list@redhat.com https://www.redhat.com/mailman/listinfo/fedora-devel-list
