RX480 crossfire 4K maybe?

Already asked about a PC build but wondered what people thought about crossfirring RX 480's and if it could achieve higher resolutions at playable framerates at 4K based on the released specs. Thinking about the future. Cheers.
 
Solution
It looks like the RX 480 drivers need some work to me. Some games it beats gtx 980, other games its behind a 970 slightly. Especially odd that in some games the RX 480 performs almost identical as r9 390x and others it loses to 390x by a decent margin. Seems inconsistent and hopefully will improve over next month or two with driver updates. I fully expect this card to perform more like a GTX 980 as opposed to the 970 after the driver updates improve to reflext GCN 4.0 architecture changes.

But yes as gokitty says its the card to beat for $220 range at 1080P. At 1440P gotta go with 1070 for now.

i wouldnt bother, it comes around the 970/390 in performance in ashes of singularity which is amd's best title, when benchmarks come out for other titles it will be lower than the 390/970 in performance, so compare the 390 in crossfire at 2160p benchmarks
 


You sure? I mean waiting for benchmarks to come out in like a couple of weeks time will show more but I'm planning on buying one card for 1080p gaming which I'm assuming the 480 would do comfortably on good FPS. Then buying a second like 6 months later to crossfire when I want to put it on a 4K TV for skyrim SE etc. Pretty games, not fast paced stuff obviously there's no need.

I wouldn't trust gokitty's advice that it's going to perform like a 390. The RX480 has a gpu clock speed that is 26.6% faster @1266 stock vs 1000 stock, with 2304 stream processors which is only 10% less than 2560 sp on 390. Add in the enchancements made to GCN 4.0 microarchitecture and 14nm overclocking potential reported to be around 1500mhz and maturely updated drivers and this 480 will leave the 390 in the dust. Most expect it to perform like an overclock gtx 980, not 970. We will know for sure in a week with reviews. I'm buying one because I only have a gtx 770 and for 229 dollars I can't justify spending around $400 for a 1070. If I gamed at 1440p a 1070 would be tempting, but the price difference to RX 480 is almost double....

Like Sleepybp most seem to be expecting the RX 480 to perform between around the GTX 980 / R9 390X not the GTX 970/R9 390. Although I'd still wait the 8 days for benchmarks before making a decision due to the uncertainty. But I'd imagine it would be about as good at 4K as two R9 390X's except without the heat and power consumption that goes with it.

Personally I'm also looking to upgrade to the RX 480 mainly though because I'm sitting on an HD 7870 and I don't want a card that is much more expensive or uses more power than what I have which left me with little to no choices for an appropriate upgrade.

yeah i agree here, wait for the benchmarks see what we get , wait for the AIB cards from MSI gigabyte ect, might find these "beast mode versions" with clock of 1500mhz or more who knows at this point. but yeah i and most people expect GTX 980 overclock type performance or r9 Fury like performance depending if we can get 1500mhz and if beast versions give us another 50-75w of power to push the overclocks beyond 1500mhz we don't know much in regards how well they overclock and what the beast mode version will be like, just got to wait and see.

so you wouldnt trust my advice eh? on paper specs dont mean anything and thats been proven multiple times before, why does the 390 with a 512 bit bus lose against a 980 with a 256 bit bus and a 980ti with a 384 bit bus? in pretty much all of the benchmarks the 480 is a lower performer compared to the 970 and 390 execpt in dx 12 titles where it edges out the gtx 970 but is still behind the 390, granted both cards are not stock reference cards. however for $200-230 it has my +1 vote, im happy with its performance for the price, however i dont think it performed how most people speculated it would

Apparently it's performing at 980 levels I just wondered how good crossfire is and if it will be able to put out at 4K at a good framerate.

i think the hype was just amped up by users more than amd meant to, great card for the price, really wondering what vega can offer. is the 480 the fastest polaris gpu?

It might be partly due to the use of AA that makes inconsistent. The THG review shows that the 480 performs worse than other AMD cards with AA on. Otherwise, it's not unexpected to have different uarch's perform differently from game to game.

good point about the AA-
Probably due to the lower ROP count of 32 on this, i think half of r9 390 before it.
At this price I think I will pick one up when after market coolers arrive in few weeks. And then use this at 1080P until second generation VR comes out or upgrade to 1440P monitor and get Vega/1080ti
