Would a crossfire Rx480 support 4K display?

Just curious, I am looking to upgrade my GPU, and was wondering if a crossfired 480 would be able to display 4k tech, even if it is at medium settings or so.

Thanks!

A single RX480 can also drive a 4k TV very well. My son has a RX480 displayed on his 4k 60hz for about three months and everything works smoothly. The display is native 4k or automatically up-scaled to 4k to sync with the tv. When you're in a game you can go to game settings and it will tell you what resolution the game is playing at. It's usually selectable, so you can play around with different resolutions.
No, unfortunately.

Not even two GTX 1080 in SLI are able to hold 60 fps + in 4k, with nice settings.
GPUs in general still have to advance some more to be able to support decent 4k.

The sweet spot right now for gaming is 1440p 144Hz, which i believe a Crossfired RX 480 can handle!

But just to point out, a single strong GPU is much better than two weaker ones working in SLI/Crossfire, because not all games are optmized to support it, what can cause visual glitches in-game.
 


Ok, that is good to know.

On a side note, I am thinking of upgrading my GPU for my PC. Right now I have a GTX 660, and while it can play the newer games on medium settings, I would like it to be higher. Would the GTX 1070/80 be overkill, or would I notice a big difference with the RX 480?

Right now I use the FX 6350, would it bottleneck a rx 480 if I upgraded?

 


Thats not true, GTX 1080s in SLI have no problem with 60fps 4k in very many titles:

As for the RX 480 in 4k, no it won't do high settings at 60 fps but hes asking about low settings which yes it should not have much of a problem with at all.

If you are playing on a 1080p screen the 1070 or 1080 are overkill. The RX 480 is killer at 1080p. Your CPU is not a major bottleneck on it at all and will not cause playability issues.
 


so is this benchmark wrong, or does a crossfire 480 really outperform a 1080? If so, whats the point of the 1080, if the two cards will outdo it for 2/3rds of the price?

The benchmark is not wrong. Check the ones I linked too.

The difference is 2 cards have the following drawbacks

1) Louder
2) More power needed
3) must support crossfire to get this performance
4) crossfire can be glitchy, and sometimes micro stutter
5) Add a second 1080 and you demolish the RX 480s, at 4k.

Single cards are always better than two. It will perform consistently in all games, and not need tweaking or specific settings just to work right.
 


It's not wrong, but does deserve several caveats. Multi-GPU support in games is better than it ever has been, and is getting better all the time, but it is still a far-from-ideal solution. For the best game experience every time, you should always go for a single-card setup if possible.

If you're buying one card now (whatever that card is) due to budget, and want to have the option to add another later to help with higher resolutions or frame-rates (perhaps because games have gotten more demanding since you purchased the first one, for instance, and are now really taxing that first card), or upgrade monitors and want to buy the inexpensive second to help, then multi-gpu can really help......knowing that it sometimes will be imperfect (stutter-y, texture/lighting flickers, or just not work at all).
 


Thanks for the tip! Right now I am considering upgrading my PC because my GTX 660 is slowing me down (or not giving me quite as crystal clear graphics as I would like). At the same time, in the future I know I would like to do 4K gaming. It seems like the best solution is to get the Rx 280 now, and next year when I do a further upgrade to my PC than get a second one and crossfire it.

As much as I agree with having one powerful GPU, at the same time I cannot justify spending $600 on a GPU that will be outperformed by 2 $200 GPU's connected (even with the issues that may come up).
 


Ok, one last question for you guys. How important is it to have a high amount of memory on the GPU? Like, should I invest in a RX 480 8gb to crossfire with another 8gb, or would 2 4gb also work well?
 


If you're planning on 4k 8gb is essential. As you get to those high detail textures you will need that extra memory.
 


If you haven't already purchased the monitor (it sounds like you haven't), give a good bit of research to high frame-rate 1440p monitors with adaptive sync:

Fast and smooth with great detail and post settings trumps higher native resolution (in my opinion, of course), and with even two RX 480....the setup will still struggle. With a great 2k monitor that setup will certainly have an easier time of it, and it will look fantastic during game-play.
 


Honestly I haven't purchased a 1440p monitor yet, and I probably won't. I have a 1080p monitor which works well, and love the display, and just purchased a 4K UHD samsung TV for my room. I am considering using my 1080p monitor when I feel like playing RTS or keyboard/mouse games, and using a controller and connecting directly to my TV.

But I may look into a 1440p monitor in the future.
