Half-Life 2: Episode Two

Joining two RV770 chips on a single PCB by means of a PCI Express switch is unrewarding in Episode Two. It is only at a resolution of 2560x1600 that the single-PCB implementation of CrossFire technology has a 5% lead over the two-PCB implementation. The Radeon HD 4870 X2 maintains its winning reputation because the GeForce GTX 280 has a considerably lower average frame rate at the highest resolution. The tradeoff of the highest performance is power consumption. As you remember, the new card consumes over 200W under 3D load.

S.T.A.L.K.E.R.: Shadow of Chernobyl

The game doesn’t support FSAA when you enable the dynamic lighting model, but loses much of its visual appeal with the static model. This is the reason why we benchmarked the cards in S.T.A.L.K.E.R. using anisotropic filtering only.

The Radeon HD 4870 X2 doesn’t show anything exceptional in S.T.A.L.K.E.R. because this game doesn’t make use of 1 gigabyte of memory whereas the other parameters of the new card are the same as those of the Radeon HD 4870 CrossFire configuration. Anyway, it takes the top position, delivering comfortable average and bottom speeds at 2560x1600.
