My ancient Atom netbook identifies as "bonnell".
[aa1][waltdnes][~] gcc -c -Q -march=native --help=target | grep -i march=
-march= bonnell
According to a post on the Arch forum gcc ignores "-march=atom"...
https://bbs.archlinux.org/viewtopic.php?pid=1423395#p1423395 This is
very important if you're trying to optimize for an Atom netbook.
