Colin McRae Rally 2005

Compare the results of the Radeon X1800 XT and the Radeon X1900 XT and you will see that Colin McRae Rally 2005 is rather indifferent to the number of pixel processors. The larger Z-buffer helps the Radeon X1900 XT win the resolution of 1600x1200, though. On the other hand, the results of the ASUS EAX1800 XT suggest that the game reacts eagerly to any increase of the graphics processor clock rate, so there must be some limitations from the TMUs section, too.

As for the “eye candy” mode, the graphics cards with ATI’s chips are in the lead there, the Radeon X1900 XT making its way to the top with the help of its architectural innovations while the ASUS EAX1800XT TOP, by its increased clock rates. The ASUS is even quite far ahead of the Radeon X1900 XT in 1280x1024: the difference is over 10%.
