Quake 4

The results of this test are similar to those we’ve seen in Prey. That’s expectable since Quake 4 runs on a modified version of the Doom 3 engine, too. But Quake 4 is older and graphically simpler, so the speeds are higher here, and the mainstream cards allow using full-screen antialiasing in the resolution of 1280x1024.

Serious Sam 2

The Radeon X1950 Pro and the GeForce 7900 GS deliver the same performance in 1280x1024, but the ATI solution provides a somewhat higher speed in the higher display modes.

Overclocking gives an edge to the Nvidia card, but the game is so heavy that you get a mere 35fps at best, which is not sufficient for a first-person shooter, especially as action-rich as Serious Sam.

The lack of difference between the results of the GeForce 7900 GT and the GeForce 7900 GS points at the fact that their performance is limited either by the number of ROPs (each card has 16 ROPs on board) or by the memory bandwidth (both cards use 1320MHz GDDR3 across a 256-bit bus).
