Even Nvidia is running away from SLI as fast as it can even for them it's not worth the money to maintain it I believe they are phasing it out. Dual 480s do pack a punch when the program using them can use them properly but the moment you get some old game you're down to single 480 performance.
Unless your 1080 suffers one of the 5-7 issues present in Paxwell and it affects you, you shouldn't switch to dual 480s. While I would happily convert ya, you wouldn't be happy probably having 50%? less performance from a card that costs 30% when running in single GPU in unsupported games.
No offense but ... you don't really have a proper bead on things.
Roughly 99% of games you'd ever think of playing on your dual 480 setup ... will make use of Crossfire & SLI beautifully.
It's not 'old' games that have an issue with multi-gpu (unless you're talking REALLY REALLY old), the 'issue' (a very minor one) is that there's no SLI/Crossfire support for the DX12 pipeline.
However, I don't know if even a single game exists that doesn't have DX11/DX12 cross-compatibility (the main DX12 titles out now, RoTR, AoTS & Hitman, all have both iirc), and there probably won't BE such a game out (at least not a AAA one) for many years (like 3, minimum). So to use your Xfire, you have to play in DX11 mode. So what?
IOW just because these are 'DX12' cards, and there's no support for Crossfire & SLI in DX12 (yet ... not sure it's impossible though) that doesn't mean these cards aren't going to work just as well in XFire as all the older AMD/ATI cards did, when playing DX11 (and below) games.
So ... you don't have to 'wait' for devs to start making use of multi-gpu low-level API coding in DX12 games to make use of two 480's in Xfire ... but you'll have to wait for games that'll make use of multi-gpu in the new DX12 NON-crossfire (i.e. non-AFR) mode. I.E. something basically none of us have even seen 'done' yet ... and hence have little idea as whether it'll be significantly better than AFR-mode, nor 'how' it will be better if it is.
Also, NV isn't running away from SLI, they're just not offering it on the GTX1060, and I can almost guarantee you that's because of issues related to the remaining stock levels of cards like GTX970, 980, and 980Ti. Not to mention, they've probably learned their lesson about putting out a $500 SLI setups that easily compete with their $650 (GTX1080) top-end part. That setup would also cut into GTX1070 sales a bit as well, being definitely faster for not that much more. Don't be surprised though when, in about 6 months ... there's suddenly a 1060 "SLI edition" or perhaps a dual-gpu on one board part.
Rumors of the demise of SLI/Crossfire are being greatly exaggerated, IMHO.
They won't 'die' unless/until the Consoles switch to DX12 or some equivalent.
Also IMHO, that might never happen, because the notion of developers writing a bunch of special code to take advantage of multi-gpu rigs specifically (code which is VERY simple when you're talking AFR, but the DX12 equivalent is not nearly as much so), when the market share for multi-gpu's is SO friggin' low ... strikes me as 'highly unlikely to take off'. I think it's far more likely we'll eventually see SLI/Xfire support ... for DX12.
BTW, Xfire support in the 480 is a MAJOR selling point vs. the 1060, and AMD should be pimping the heck out of that.
I think 8MB is overkill on a single card of this performance level, but 2 of them in Xfire? NOW, you're probably talking about enough horsepower to make some use of a framebuffer of that size ... you can probably rock some 4K games w/very high res textures and such with 2 of these cards.
If one of the AIB's comes out with a, say, $400 dual-gpu version of the 480 8MB, with everything in the power section tweaked well, so there's minimal throttling, one that holds a solid OC ... they could have themselves a monster seller on their hands ... a card that competes well with the 1080 on most titles ... for $400? There'd be a BIG market.
Then again ... maybe Vega is gonna fill that role ...Edited by brettjv - 7/21/16 at 1:20am
