Beating the GeForce GTX 1080 at 4K How do two AMD Radeon RX 480 video cards perform in CrossFire?

I thought this is worth a discussion thread on it's own as there is quite a price difference between a pair of RX480s and a GTX1080.

As usual it's great when crossfire/SLI works well but if there were for example 10 DX12 games in that review, only about 1-2 of them would scale at all unfortunately. SLI is also awful for DX12 support. That's fine for some people but I prefer to have all the performance all the time.

ditto. I wouldn't even consider SLI/CF unless 80%+ of games support it fully. A lot of my games are Unity engine games which has no support. So no chance I'm getting 2 GPUs

i would be quite happy to swap out my fury for 480 crossfire but my problem is if the game does not support xfire/sli i would be worse off than a single fury, im keeping a close eye on multigpu to see if things improve

flopper · 6 Jul 2016 at 08:40

expected but no one in their right mind recomends sli or crossfire.
Unless the games you play constantly support it well

Same here, however we are all in the hands of the developers and those developers see CF/SLI as a very small percentage of users. If Adored TVs Masterplan videos are to be believed and Raja has hinted that they are going to be pushing for better mGPU support with their cards (Hence all the development with the developers recently and giving them Fury Pro Duo boxes) then hopefully it will pan out and be more successful. Nvidia would have to respond in kind and we would all get better mGPU support.

I certainly would entertain 2x RX480 as they are reasonably cheap to do this with. I think the guy at hardware unboxed did a crossfire 480 review and approx 4/5 of the games worked and around about 6 titles didnt due to bad implementation or no support for mGPU at all.....so a little better than I first thought.

its just seems to be the way of things lately, back in the day my 5770 crossfire matched the 5870 and was cheaper and worked on pretty much everything i played.

if the support was there i would have no worries about using crossfire

I have been running Crossfire/SLI systems since around 2006. My next upgrade will be to a single card solution. I'm fed up of a lack of support / late support for many games and I don't see the situation getting any better.

Multi card systems are almost becoming a benchmarking tool and little else.

Crossfire is pointless, as we all know they simply won't work/scale in Nvidia titles...which is lots of games.

People are probably point out that SLI don't work too well neither on Nvidia games, but the ironic thing is for the so-called "AMD titles" where Crossfire works well, SLI work and scale quite well too.

So basically...what-da-hell's wrong with the Nvidia titles?

Open source vs closed source. Basically.

Read much about AMD being open source and Nvidia Closed source. It's hardly new or secret information. I though this was well known?

JanM · 6 Jul 2016 at 09:57

I'd avoid crossfire or SLI just because so few games support it. I just go with the most powerful graphics card I can afford.

JediFragger · 6 Jul 2016 at 10:04

Given the current state of Crossfire I wouldn't have 2 of them given to me!!! Utter pish

I am certainly not a programmer but SLI and CF is down to the developer and what engine and libraries are being used and as far as I am aware, some engines just don't like mGPU but this isn't down to the fact that NVidia or AMD sponsor the game. The UE4 for example isn't great for SLI and it uses the deferred rendering technique and as such, doesn't play nice with SLI or CF. The Unity Engine is the same I believe but not really looked into it but as for NVidia being closed source and AMD open source, whilst again I would disagree for the most, it won't make a difference if the developer goes with those engines who sponsors the game.

Those minimum figures. So bad

Yes, it is well known and no secret that GW's gets in the way especially when it comes to AMD game optimisation/mgpu.

Witcher 3 had to implement a tess slider for Nv users(as AMD could override in the CCC).

Nv don't have a problem nerfing a higher percentage of their own customers performance never mind the lower amount of AMD users.

Yet when AMD stamp their name on a title, there is zero black box AMD specific code getting in the way of any vendor hence why they usually run well for all.

And we all thank them for being so nice about it

nVidia would rather beat you with a stick rather than give you something for free

tommybhoy · 6 Jul 2016 at 14:18

Agreed.

We can't get enough of their products no matter even when they ridiculously price them.

If AMD want to get back in the game, they need to get down n dirty like the rest of them, Nv didn't get where they are playing Mr nice guy.

We were talking about how SLI and CF don't play nice with some of the modern games. GameWorks breaking SLI and CF is a new one but go for it
