Performances in a nutshell
We calculated the average of all benchmark results, gave the same weight to all games, and attributed 100 to the GeForce 7800 GTX in 1600 x 1200.
If the GeForce 7800 GTX without antialiasing was already slightly ahead of the Radeon X1800 XT, the new one increases this situation and is 26.3% faster!
Asus´ dual 7800GT is in the lead with 5 to 10% higher performances than the GTX 512. A single 7800 GT is almost 15% faster than the X1800 XL. Average performance gains of 15% due to the new architecture aren´t enough!
With antialiasing activated, the X1800 XT is 18% faster than the 7800 GTX. The GTX 512 catches up and even takes the lead by being 20% faster than the X1800 XT. The X1800 XL finishes at the same level as the 7800 GT. X1K architecture improves performances by an average of 20% in this mode.
In HDR, the X1800 XT is comparable to the 7800 GTX. The 7800 GTX 512 is just in front. X800 XT performances are strongly reduced as it only supports HDR in Half-Life 2.
In HDR and AA, the Radeon X1800 obviously dominates because it’s capable of using it in three games compared to only one for other cards.
