AMD announced yesterday (via IDG News/Businessweek) that it will be dropping the ATI brand and will attach the AMD name to the Radeon, FirePro and Eyefinity offerings.
ATI's graphics products have long been used in Apple's Macintosh line, most recently with the 2010 Mac Pro and the Radeon HD 5870 Card. AMD acquired ATI in 2006, but has kept the ATI brand until now.
The company says the change in brand name won't affect any graphics product offerings or plans. The brand transition should be completed by the end of the year.
