Aliens vs. Predator (2010)
The Radeon HD 6790 is ahead of the GeForce GTX 550 Ti by 17 to 20%, which is quite a lot considering that they come at the same recommended price. The HD 6790 is 10-14% faster than the HD 5770
Lost Planet 2
Nvidia’s products are unrivalled in Lost Planet 2. The Radeon HD 6790 cannot match the GeForce GTX 550 Ti here, although the gap is rather small (4 to 10%).
StarCraft 2: Wings of Liberty
The Radeon HD 6790 is as fast as the GeForce GTX 550 Ti in the FSAA-less mode but loses its ground as soon as FSAA is enabled. This is a peculiarity of the game engine.
The Radeon HD 6790 is again superior to the GeForce GTX 550 Ti, yet both are too slow for playing the game comfortably. The Radeon HD 6790 is also 2-6% ahead of the HD 5770 and 20-21% behind the HD 6850. So, the new card is not exactly midway between the two older products here. The Radeon HD 6870 stands out among the faster solutions although the overclocked HD 6850 and GTX 460 are but slightly slower.
