The second test puts a heavy load on the vertex processors when generating the vegetation. The vertex processors count is in favor of the Sapphire card (8 against the GeForce 7800 GT’s 7) and the Sapphire’s are also clocked at a higher frequency (500 against 440MHz), That’s why the Sapphire RADEON X1800 XL is confidently ahead of its rival in this test, the gap increasing even more in high resolutions.
In the third test, which stresses mercilessly the pixel processors of the card, the Sapphire RADEON X1800 XL shows better results in low resolutions, but the GeForce 7800 GT catches up with it in higher ones.
Thus, the total scores of these two cards are only true for low resolutions. If the scores were based on the results in high resolutions or with enabled full-screen antialiasing, the GeForce 7800 GT wouldn’t be so far behind. And like in 3DMark03, we can’t see any performance growth from our using the new Catalyst.
