Radeon X1800 XT, formerly known as R520, is the new high-end chip from ATI, directly competing with GeForce 7800 GTX from nVidia. We've got a reference sample for this model from ATI, so we will compare its performance to other members of the Radeon X1000 series, to previous ATI chips and also with competing products from nVidia. But don't get too excited: video cards based on Radeon X1800 XT will only reach the market in one month from now..
