Performance in Simulators

Colin McRae Rally 2005

The number of pixel processors and their working frequency exert the most influence on the graphics cards performance in Colin McRae Rally 2005 . It doesn’t matter that much how efficient they are with complex shaders, because there are none in this game. RADEON X700 features 8 pixel processors, while RADEON X1300 PRO has only four of them. And even though higher working frequency makes up for it in a certain way, it is still not enough for the newcomer to win the first prize, so RADEON X1300 PRO has to put up with being the second fastest. Unfortunately, we haven’t answered the question about what prevents RADEON X1300 PRO from winning in high screen resolutions: in 1600x1200 its speeds almost drops down to the level of GeForce 6600. As for the eye candy mode with enabled full-screen anti-aliasing, the performance gap between RADEON X1300 PRO and RADEON X700 is minimal in this case, at least in low resolutions. You should also keep in mind that the new ATI solution offers smaller “safety factor” than the predecessor: just look at the numbers for minimal performance.
