[AnandTech] GeForce+Radeon: Previewing DirectX 12 Multi Adapter with Ashes of the Singularity - Page 11

post #101 of 326
this looks propa fun I cant wait till I can try it out, I just got this 960 4gb not that impressed by it so im gona get a fury, still got a 470 gtx and 660, wonder if I can run with all of them and get ashes running at 4k max settings biggrin.gif

this is actually an interesting question. the one to benefit this the most are laptops. Could set a new standard minimum performance lines for select dx12 games for mobile space if this could work with IGPUs. Would also help intel in the way that the minor CPU gains could be offset by adding the igpu to the dgpu's performance(as intel has increasingly been leaving more die space for the gpu nowadays since cpu efficiency is barely budging). Of course, this only affects games that will utilize AFR

I wouldn't count on it. I'd sacrifice them all for a good single card. Huge power draw, plus you'd need at least 24 pci e lanes on the cpu to run them 8x/8x/8x

In 2016 there will still be way more DX11 games than DX12. Games you either got earlier, or not AAA games which are not DX12 compatible.
So if you buy GPU only based on DX12, you will cripple your performance overall. In 2017, it might start to change. In that point, then, it will be wise to start thinking forward. And by that time, both AMD and Nvidia will switch GPUs, and you have no idea what will happen then.

Right now, FuryX+980TI is great for AoS (I don't know about fable though, of batman, or any other DX12 game coming), because it uses furyX for async compute and the raw power of the 980TI. But next year, this might change with pascal being more compute oriented than maxwell, because of HBM2, and AMD going with 14nm but most likely won't change overall tech.

So right now, concentrating only on DX12, is a bad idea to those who plan to buy their GPUs in the coming year.

Nobody is looking for a fight here.

I agree with pretty much everything you just said. Further I agree with what others have posted along these lines.

HOWEVER; it doesn't mean that this shouldn't be pursued. In five years, it would be nice not to have to buy GPUs in "sets" for SLI or Crossfire to get multi-gpu power. Somebody like me, who switches vendors frequently absolutely sees a benefit to this coming together and working out.

Saying about this feature, "I don't really see a point to this" or that it's "a waste of time" or however some have verbalized it is really shortsighted and/or reveals that some feel threatened by the loss of superiority for their respective GPU camp of choice.

There really isn't much else to say. If people feel "threatened" or that I'm somehow trying to start a "fight" (a laughable assertion on a forum); then that's on them.

Don't forget that this feature is kinda old.
Remember Lucid?
It was a nice idea. It showed increased performance. But it died.

Currently the idea is nice, but the question is when games are out of alpha/beta and drivers are fully ready, how much it will really matter? Especially if when both nvidia and amd roll out new hardware next year, when DX12 will actually start to matter, we will see the same thing?

Also, a small note, that choosing the main GPU might be more of an issue. When you have to switch which card is the main card between games, and how it works, having to switch the cables, suddenly you lose g-sync or freesync, those things will also matter whether people will actually go to multi vendors, or stay on the same boat.

This isn't comparable at all.

But...how about 2xRadeon - 1x Geforce or the other way around? Or quad? biggrin.gif:D

I was wondering if someone can test Intel +AMD+Nvidia when the bench is out. Does it support iGPU?

If anything, Lucid Hydra demonstrated the difficulty of getting cards of different performance levels to work well together. Heck, even AMD's Crossfire, which allow mixing of for example 290 and 290X, force the faster card to run at the speed of the lower card. Sure, it may be easier with DX12 due to more direct programming, but that doesn't mean it's going to be a walk in the park.

I would rather prefer that game developers work on getting split frame rendering to work with very good scaling and no tearing on identical cards than futz around with combining cards of different performance levels in alternate frame rendering. SFR would have much better latency than AFR, especially with more than 2 GPUs.

I don't deal with multi GPU and prefer to have a single card in my system.
