I'm pretty sure AMD (or nvidia, for that matter) themselves don't really much care for it either - the pressure to rebrand mostly comes from big box OEMs like Dell, HP, Lenovo, etc... they'd very much like to keep putting the same el cheapo die in their boxes, but "keep up" with the latest gen at the same time . Can't have it all, so the next best thing is to keep up with the naming scheme.

Either way, since when does XS give a rat's ass about low end crap?
