Quake 4

Despite full-screen antialiasing and OpenGL, the Gigabyte Radeon X1900 XTX and Gigabyte GeForce 7900 GTX have the same performance in a normal gaming situation with lots of shots and action. Their average performance is over 100fps in all the resolutions. The minimum of speed is quite high, so you won’t be disappointed when playing Quake 4 on a top-end graphics card.

Serious Sam 2

The game employs a large number of pixel shaders with multiple texture lookups and prefers graphics cards with more TMUs on board. In other words, GeForce 7900-based solutions have a certain advantage in this test over Radeon X1900-based ones.

Although the average performance of the Gigabyte GeForce 7900 GTX is quite high in 1280x1024, its min speed is as low as 13fps, making impossible to play the game’s most complex scenes normally. So, you have to limit yourself to 1024x768 in Serious Sam 2 if you insist on using FSAA. Note also that the Gigabyte Radeon X1900 XTX has a better minimum of speed than its opponent, but a worse average performance. The bigger reserve of speed must be due to the card’s having two times more pixel processors, even though they may not be getting as many textures as they could process.
