NVIDIA GeForce GTX 780 Ti: Taking GK110 To The Max

CrossFire vs. SLI: AvP and Hitman

We also had the privilege of pairing up a couple of GeForce GTX 780 Ti cards to test in an SLI configuration. For these tests, we’ve compared the GeForce GTX 780 Ti SLI setup to a pair of original GeForce GTX 780s and a pair of Radeon R9 290X cards running in CrossFire mode. We’ve got frame rates, scaling percentages, and FCAT results from AvP and Hitman up first...

The Radeon R9 290X CrossFire configuration no only offered up higher frame rates at both resolutions, but doubling-up the cards showed better scaling as well.

Technically speaking, frame times were also more consistent on the Radeons in this game, though the variations on the GeForce cards were very, very small. The highest spike on the plot was right around 20ms, and typical variations were only a couple of milliseconds at worst.

Hitman Absolution also scaled better on the Radeons when doubling-up on the cards. And frame rates were higher on the Radeons too.

The Radeon’s frame times, however, were far more variable in this game than the GeForce’s. All of the configurations we tested offered up frame times that were consistently below the 22ms mark, but the variations between frames on the Radeons were much larger.
