Quake 4

Despite the turned-on full-screen antialiasing, all the graphics cards behave alike in resolutions below 1600x1200. Only the Radeon X1800 XT stands out among the rest because it has better frequency characteristics and twice more of graphics memory. It wins 1600x1200 resolution, too.

Thanks to its overclocked frequencies, the EN7800GT Top Silent is only a little slower than the Radeon X1800 XL while the reference GeForce 7800 GT is 15% slower than the ATI solution although Quake 3 runs on a modified OpenGL-based engine from Doom 3. It’s not very important, however, because every card makes the resolution of 1600x1200 playable here.

Serious Sam 2

We tested the game using a demo supplied with it; speed was measured with Fraps.

The Radeon X1800 XT is the single graphics card that can provide an average frame rate of 55fps and higher here – it’s just because it is the single card among the tested ones that has 512 megabytes of graphics memory on board. The other cards come with 256MB of memory which is not enough for Serious Sam2 at its maximum graphics quality settings.

Anyway we can see that the GeForce 7900 GT works much better than the GeForce 7800 GT or the ASUS EN7800GT Top Silent. The latter two cards have 20 TMUs whereas the G71-based card has 24 and this game makes wide use of pixel shaders with multiple texture lookups and appreciates high scene fill rate.
