Sapphire AMD RX 470 Crossfire Graphics Card Review

Doom

Currently, Vulkan doesn’t support multi-GPUs either and despite my best intentions, no benchmarking runs could be recorded. When authorising Crossfire with Vulkan, the game refuses to start and you’ll be greeted with a black screen.

  1. Well we might see better multigpu support now that Microsoft is trying to push it by giving free examples and code on Github.
    Thanks for the review.

    1. You’re welcome! Yep, I hope so but not expecting any change for a while, considering doing a similar article with the RX 460 but could require some tweaks with the games.

      1. I don’t know how many will be interested for an RX 460 CF setup. Two RX 460 will have less stream processors and still cost more than one RX 470. Probably for that reason there are not going to be enough or any reviews out there, testing a CF setup with two RX 460. eteknix could end up as one of the few having such a review.

  2. FYI Ashes of the Singularity mGPU only works if Crossfire is disabled since it uses the cards independently rather than “synced”

    1. I go into detail why that’s the case to show the current state of Crossfire/SLI in the usual test bench including DX12 and Vulkan. Then I included Shadow of Mordor to show that there is cases when the scaling works pretty well. Surely, the issue is that many games don’t support multi-GPU and changing the testing to show ones which do seems to give an unfair reflection.

        1. I can only benchmark so many games within a certain time period and I once again state that the idea of changing the games doesn’t show how Crossfire works in our test bench. If people prefer to see the benchmarks for Crossfire only games even if they’re old and doesn’t show the experience people will have with modern games then that’s something to look into. Please don’t make demands, I’m only trying to produce honest content and reviews are a length process especially with NDAs.

      1. Also , where’s the full comparison vs other cards on shadow of mordor? Can’t help but get the feeling that the review is done in such a way as to trash and downplay the idea of crossfire in favor of subsequently recommending a higher specced, higher price Nvidia gpu…..

  3. Someone pointed this out and the comment was removed. This is from the oxide developers specifically:

    “For best performance, disable Crossfire/SLI directly in the AMD or Nvidia Control Panels”
