NVIDIA’s new card is not so much faster than its rival in this RPG-like test. The memory subsystem performance is not a key factor here because the scene is limited in space. To be exact, the GeForce 7800 GTX 512 is not more than 1fps faster than the RADEON X1800 XT 512MB.
The cards behave here in nearly the same way as in the first test. The GeForce 7800 GTX 512 is increasingly farther ahead of the RADEON X1800 XT 512MB as the resolution grows. Moreover, even the less advanced GeForce 7800 GTX manages to overtake the senior RADEON X1800 model in the hardest video mode.
So, the total score of the GeForce 7800 GTX 512 in this benchmark seems quite correct, but we should note that the gap between it and the RADEON X1800 XT 512MB would be wider if 3DMark05 used a resolution higher than 1024x768 to calculate the total performance score of a card.
