    so this single game shows that Two 480 beat marginally 1080 and save plenty of bucks.so is it worth to have 2 cards? Because we know SLI or Crossfire have their own issue.some games give bad performance or other problems on two cards.so can someone please tell that is it worth to have Two 480 than one 1080 in my pc?because i gonna buy new card this month.

    sorry for bad english.It is my third language.

    If you want to play Ashes all day then perhaps, otherwise no.

    Less hassle with 1080 really and more consistent. 2x 480 might give you similar performance for less bucks. But in reality you won't see it always.

    It just depends on what you are after anyway. And well if that is your current motherboard you cannot even have two gpus.

    Yeah nothing beats single GPU solutions. Dual GPU solutions have too many cons.

    Aost isn't a good example of average gaming performance when comparing AMD to NVIDIA. Pinch of salt comes to mind.

    The graph is a complete nonsense from multigpu point of view.

    2 480 GPUs in CFX at only 51% usage equals the performance (fps) of a single 480 GPU at 102%.

    That means a single 480 at 102% gives a little more fps than a 1080 at 98.7% 62.5 fps vs 58.7 fps. LOL In which world a single 480 perf is equal to a single 1080?

    If we equal usage in both , a single 480 vs a single 1080 GPU performance at 100% the FPS we will get from each will be more or less equal.

    A complete nonsense.

    Even if this was true a CFX scaling of 51% in 2 gpus is A BIG S****.

    ya i m agree with u guys two cards always have their own issues.Thats why i never went for two cards whether its cheaper or whatever.so we need full Benchmark for SLI 480.

    I could get 3 way for less than a 1080 lol.

    3 way nvidia works well enough, drivers are top notch, just wish they had AMDs scaling.

    We previously hard a chart showing the results of unannounced AMD cards. In those, we saw that two "C7" cards in crossfire gave 93% the result of a single 1080 in 3DMark. We now know that the C7 is the AMD 480.
    I edited my post as the forum wouldn't allow linking this chart here. (website was censored)

    If you buy two 8gb 480, it would cost you 460$ instead of 600$ for a 1080.
    This means you are paying 80% of the price.

    93% the performance for 80% of the price is a better offer. BUT. Crossfire and SLI are both troublesome. I personally do not like using two cards together.

    If you have enough money, it might be better to buy a single 1080 instead. Keep in mind that this doesn't take into account DX12, where two 480 will almost certainly beat a single 1080. But DX12 games are gonna take a bit to come.

    ... really dude?

    Also surprised at the comments from non multi gpu users about multi gpu. Once you go multi and taste the power of a 30k firestrike or 35k+ 3dm 11 score it's hard to go back.

    Nvidia mostly flawless and amd is just late with profiles.

    Guru3d please Full benchmark of 480 single and SLI.Specially SLI because AMD bet their money on SLI 480 against single 1080.Its fine strategy against expansive Nvidia.

    Two of 480's in aots are comparable to dual 390's in aots. That is a good reference point anyway. The cards ain't slow for sure. 1080 won't win two of these in aots. But will in most of the other games where xfire won't kick in anyways.

    Good reference point would be xfire/sli of 290x/290/390x/390/980/970 or 295x2.

    I have no clue what that random number 51% was on the chart. I've seen single getting 34-35fps on aots extreme preset and two getting 58-59 on aots extreme, where 1080 gets 55.

    And on crazy 45 for two 480s and same for 1080. All stock of course. Talking about heavy batches here.

    REALLY...dude. :)

    Start any game who gives you a 50% GPU usage on both GPUs using CFX and run it again in single single gpu mode with 100% GPU usage.

    Compare FPS....

    Dude 3d mark,firstrike or any mark gives proper performance for SLI or 3 way SLi but its not like that for FPS in games.Gamers have nothing to do with Benchamrk firstriker or any.

    I didn't notice this during the event for some reason. 2 480's in CFX at 50% scaling is equal to a single GPU but beating a 1080? Something fishy going on there.

    When they stopped with CAPs it just went downhill and I really don't understand why they compared to the 1080 like that in that game.

    How many DX12 games are utilizing both your gpus?

    Don't assume a direct correlation with the performance and utilization.

    Currently not playing any DX12 games. The only DX12 game I have is Tomb Raider. If I were to play that, it would be on my nVIDIA SLI rig.

    While nVidia basically tries to go away from SLi. AMD tries to make CF better. They have practically 100% scaling for VR.
    On normal games it is not that great. But we do not know yet what kind of CF improvements on HW level Polaris has. (if any)

    But, there was already hinted card with 2x Polaris 10.

    While GTX 1080 would be huge upgrade for you, that price tag is totally not justified for 16nm Maxwell.
    RX 480 will be nice upgrade and will last for quite some time. +You can get pretty good Freesync monitor with cash you save.

    And even if you happen to be dead set on gtx 1080, wait till there are full Polaris reviews and it is on store shelves as it will likely force nVidia to reduce GTX 1070/1080 price.

    If both GPU's are running at 50% load, then it would equal to a single GPU, right?

    Loads are a bit more variable than that for both CPUs and GPUs. What does a 51% "load" mean? Shaders? Pipelines? ROPs? Memory controller? It all depends really on where the bottleneck lies. If that GPU is reporting 51% of its transistors doing "something", that doesn't mean that it actually can use the rest that are in a state of waiting. NVIDIA cards wait for their pipelines for context switches and GCN cards wait for the tessellator etc.
