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.

There's a typo on the Specification Comparison chart, you put 7970 instead of 7990 for the first one.Great review!

There is no typo. It IS 7970 CF. CF stands for CrossFire, which means two 7970s. Therefore the comparison makes sensedeestinct - Thursday, April 25, 2013 - link
Ah sorry ignore my previous comment....i misunderstood what you saidjust4U - Wednesday, April 24, 2013 - link
One thing that bother's me about this and Nvidia's offering. You sort of "hope" (expect.. would be better..) that these types of cards would bring something more to the table besides just a dual stack of their top end card. Higher clocks, better memory.. something.jeffkibuule - Wednesday, April 24, 2013 - link
Power savings compared to 2 cards in SLI/CrossFire. Ability to fit in a smaller chassis. Use of the best binned chips possible. But yeah, it really is for the 1%.mr_tawan - Wednesday, April 24, 2013 - link
Single card also means no need for SLI/Cross Fire mainboard (which save money a bit).Rookierookie - Wednesday, April 24, 2013 - link
I don't know if you are spending $999 on your graphics card that saving money is really an issue. You are not likely to be using a low-end motherboard, and many of the high end motherboards support SLI/Crossfire anyway.just4U - Wednesday, April 24, 2013 - link
The power draw appears to be (in my opinion) partially due to the lower speeds. The cards are for a select crowd but I don't see the draw. There should bring something new to the table which would help to entice buyers.Ktracho - Wednesday, April 24, 2013 - link
There is a fair amount of variability in power consumption from one chip to another. Always choosing two chips that are on the low power side makes a significant difference compared to two chips chosen at random, because in the latter case, the design has to account for the worst case - two chips that are on the high power side.stren - Wednesday, April 24, 2013 - link
5 real monitor outputs and SFF is what it's about for those with unlimited cash, otherwise you'd be better off with mulitple lightnings or matrix cards. Until they support 2D lightboost then I'll be sticking with Nvidia.
