Call of Duty
The Sapphire Toxic X1900 XTX and the GeForce 7900 GTX both allow using resolutions up to 1280x1024 at the “eye candy” settings. In the higher resolution, the results of both the cards are far below 60fps, so you cannot play the game normally. Like in the previous cases, the higher clock rates of the Sapphire card don’t provide any real performance boost relative to the standard Radeon X1900 XTX.
The senior members of the GeForce 7800 and 7900 families are slightly ahead of the Sapphire Toxic X1900 XTX in Doom 3 because the engine of this game is oriented at the GeForce 6/7 architecture. Anyway, even with a lower fill rate and lack of UltraShadow-like technologies the Sapphire card is still capable of providing a good frame rate in all the standard resolutions, including 1600x1200. It is the high-efficiency ring-bus memory controller than helps it nearly reach the level of the GeForce 7900 GTX in the highest resolution despite the considerably lower memory frequency.
