AMD CrossFire Vs. Nvidia SLI Scaling Analysis

Benchmark Results: Crysis

At 1920x1080, Crysis performance scales alongside relative cost, although the Radeon HD 5830s in CrossFire perform a little better than expected. This is the cheapest solution to provide a minimum frame rate of 30 frames per second (FPS) at very high graphics settings.

When the resolution increases to 2560x1600, the story remains the same for the most part. The only solution able to provide over 30 FPS minimum at this demanding setting is a pair of GeForce GTX 480s in SLI.

    Nvidia wins this war thanks to the larger standard framebuffer. ATI needs to pick up in this area a bit, as 1GB framebuffers have been around for a while now. Looking foward to another article based on the next gen cards a few months from now. Should be interesting. =)

    Good job to both ATI and Nvidia on this generation.

    BUT.. i would have preferred 2-3 way SLI with GTX460's.

    gtx 460 can only do 2 way sli

    The SLI scaling is one place where Nvidia wins almost all the time, but ATI has improved a lot though, it still need to work harder if they want to have a complete win over Nvidia...

    yeah it a shame that it can only do 2 way sli. We would get 3 way gtx 470 sli level performance at amd radeon power consumption

  • Nice article. I've made some charts, based on the data in this article, that reflect SLI and CrossFireX scalings. Nvidia's victory is clear cut at 2560 x 1600.

    Also, when it comes to GPU discussions, the comment sections of Tom's and Fudzilla are swarmed by fanboys of 1 certain team. (Can you tell which? It's already obvious here, but much more so at Fudzilla.) Competition is good. Don't downrank comments just because they favor the "other" team.

    12 million people with WoW subscriptions, new expansion due 12/7/10, lot's of vid cards being bought for that purpose . . . I know its not easy, the format may have to be different, but can you guys consider including WoW in the benching runs?

  • Yet another reason AMD would be happy to never have board of theirs allow SLI
