With a higher GPU clock, the GeForce GTX 550 Ti has 15% more processing power than the GeForce GTS 450 with a 70% higher bandwidth thanks to its larger memory bus!
For this test, we opted for 3 resolutions: 1680x1050 without and with MSAA 4x and 1920x1200 without MSAA, with the exception of Crysis Warhead and Far Cry 2 which were tested in more modes. We set the graphics options high but not at maximum in the most demanding games.
We have also decided to stop showing decimals in game performance results so as to make the graph more readable. We nevertheless note these values and use them when calculating the index. If you’re observant you’ll notice that the size of the bars also reflects this.
The Radeons and the GeForces were tested with texture filtering at the high quality setting. All the Radeons were tested with the Catalyst 11.4 beta (8.84.3 beta 2) driver and the GeForces with the beta 267.59 drivers.
