ATI Radeon video cards?

Ati radeon rage 6 and a ATI RadeonR600 are this the same card or totally different?|||As far as I can find there is no difference.|||No different, ATI renamed RAGE 128 Pro (rage 6) to radeon R100|||R600 is ATI's chip series used in there HD2000 and 3000 series cards. I think the lastest R700 used in there HD4000 series cards. Rage 6 (R100) is a much slower and older technology.
