AMD Radeon HD 7990 Review: 7990 Gets Official

Bioshock Infinite

Bioshock Infinite is Irrational Games’ latest entry in the Bioshock franchise. Though it’s based on Unreal Engine 3 – making it our obligatory UE3 game – Irrational had added a number of effects that make the game rather GPU-intensive on its highest settings. As an added bonus it includes a built-in benchmark composed of several scenes, a rarity for UE3 engine games, so we can easily get a good representation of what Bioshock’s performance is like.

We knew from the moment the first reviews came out that we wanted to use Bioshock Infinite as one of our new games, but we weren’t quite sure what to expect. In the end there’s almost a clean split between the relative performance of single-GPU cards and multi-GPU cards. As such while the 7990 and 7970GE CF are clearly in the lead over their NVIDIA counterparts at 2560, the GTX 680 slightly edges out the 7970GE.

In this case AMD is seeing better multi-GPU scaling than NVIDIA, giving the 7990 the edge here in all resolutions, with the 7990 besting the GTX 690 by 6% at 2560 and a very sizable and unexpected 20% at 5760. It will be interesting to see what the FCAT results are like once we have those back in order to confirm whether Bioshock is as smooth on AMD cards as it appears at first glance.
