Game 3

The third test is intrinsically the same as the second, so all the above-said things apply here as well.

There’s no gain from the larger memory amount even with full-screen antialiasing enabled.

Well, there’s no difference between the two RADEON X800 XL models even at the maximum-level antialiasing.

Game 4

The fourth test contains complex pixel shaders but doesn’t operate with large amounts of graphical data, so there’s again no difference between the 512MB and 256MB versions of the RADEON X800 XL.

The same is true for the “eye candy” mode. The RADEON X850 XT/XT Platinum Edition, with high core frequencies, show their best in the fourth test.

Even with enabled 6x FSAA, the RADEON X800 XL 512MB has no advantage whatsoever – it performs exactly like the model with 256MB of memory. Thus, the separate tests agree with the overall scores: 512 megabytes of graphics memory don’t give any bonus to a graphics card in 3DMark03.
