+Gamers Nexus said they think multi-make like AMD and Nvidia together would be extremely rare, but I don't think so. AMD cards and Nvidia cards are slightly different and do different things, and the performance here in Ashes is testament to this. AMD cards crush raw computing which is why they're selling out for crypto mining. Ashes of Singularity is an extremely computation-heavy game with tons of objects. It would not surprise me if it's actually optimal for many games to run an AMD card and an Nvidia card.
You guys really should be testing this Discrete Multi GPU with two 970s *not* in SLI against two 970s in SLI, as well as two of 390X. Otherwise the data just doesn't really tell us that much other than SLI possibly having bad scaling for this game in particular.
i'm actually really exited for this Dx 12 feature. the world all ready has a multitude of older cheaper gpus. now they just being made useful. honestly im surprised something like this is being developed because well people wont have to go and buy better gpu's as time goes on and have no other option. in a way this feature is very economically friendly and would suit allot of budget gamers like myself. i recently brought a gtx 970 and gtx 980 for just under $500 AUD. im sure using multi explicit gpu rendering it could easily outperform some of other top of the line graphics cards now and in the future
hey odd question, is there a limit on how far back you can go between gpu generations, i was wondering (because AOTS crashes when i turn on the mixed gpu funcxtion) if i could (just for laughs) mix my R9 380 with my RX480?
Does anybody know if I can SLI a gtx 970 EVGA card with a gtx 970 MSI card without any problems? Have been watching this card this guy has up on craigslist for like a month now and it has gone from $200 all the way down to $125 but I wanna be sure it will work with my EVGA card before buying it.
You should test for those guys out there with something like an A10-7800k Apu (or even AM1 platform) & an dedicated card like an 750ti & 360 or something to see if they get noticeable gains including the on die chip into the equation.
Did you guys have any issues installing both GPU's in a single system ? Any Driver conflicts or anything like that ? I'm about to get a GTX 1080 and I want to leave my Fury X in the system I'm wondering if they'll actually play well together even if one GPU isnt being used. (Have both of them in the system just in case there are anymore games that come out supporting Explicit multi adapter in the future).
Or would you guys just recommend I sideline the Fury X for now ?
http://imgur.com/b7f9LBo Yeah theres no issues with having them both installed, all tho its a bit pointless. I tried playing a game through the Fury X with a monitor connected to it and the game still rendered on the GTX1080, lol dont know how that works but yeah. I eventually just took the fury X out.
If you maybe render videos or do computational things on your PC I can see both the 1080 and Fury X in the same system possibly being a benefit but other than that not worth.
can you guys update this video with the Pascale? i.e. pairing an older 980ti in sli with a 1080 vs two 1080's. this is now a possibility with dx12 and gives consumers more options when upgrading hardware.
I have a gtx 970 as my main card, and a ton of old graphics cards that I have laying around for the sake of collecting. Do you have any information on what would happen if I for instance had my 970 in the mainslot, and used a gt 430 secondary? Would that do any difference giving that additional gig of mem or would that actually hinder performance?
+Renan Zacaron It doesn't matter DX12 manage the cards with their drivers so it knows how to access each card.
If it can already mix 2 diferent brands each card with diferent architecture i think it won't be an issue to access the vram :)
8:12 Yeahhhh, I would say that if Ashes is at ALL representative of what is to come with DX12, then my (and many other gamer's) dreams very well may come true!
I REALLY wish you had Crossfired 390x's though, to compare against the multi vendor dual GPU setup..
Also, I thought the 390x compared to the 980 regular in both price and performance (in DX11) currently. Oddly enough if you compare just prices on Newegg today - the 390X is a good deal cheaper than their 980 price, but elsewhere not only is the 980 cheaper, but the 390x is more expensive as well - making them both close to even on pricing as the mean average, though the 390X Newegg price is lower than any I have seen for the 980 regular...
I wonder if AMD gave them a discount on said GPUs or something - as Newegg is pretty much the default for most people looking at PC parts cost...
IF Implicit multi GPU becomes FULLY supported on basically every DX12 title, IT MIGHT actually make sense to build with a 980ti and Fury X for example!
The 980ti would allow for G-sync which DOES perform better than FreeSync, also the 980ti has MUCH more tessellation than the Fury X, where the Fury X has more RAW compute power, as well as Async compute AND that HBM memory!
It is my SINCERE hope that I will be able to build a system that utilizes the BEST OF BOTH COMPANIES when it comes to graphics!
Ashes of the Singularities approach seems to be combating the gpu war's and even nvidia's dickishesness in their approach to sharing proprietary whatever-have-u kind of shit that amd has always been forthcoming with
I don't see it as a weird thing to do. This way you don't have to worry so much about Nvidia's bullshit because you'll actually have one of their cards in your system. My question is whether you'll be using Radeon Settings or Nvidia Control Panel with a setup like this. Or maybe both?
I think anything below a 7970 will just be a hindrance for most things. Also keep in mind that the AMD card needs to be in slot one, and the Nvidea card needs to be in slot two to get the most out of a combo. Well unless the Nvidea card massively outperforms on a head to head basis, then you need to experiment with both and see which is better.
Any way you could throw 2 390x into the equation? I'd love ot see it how it stacks up.
Also there is a HUGE reason to have a version of each brand. It will eliminate the retarded gameworks bottleneck you have for AMD cards and also remove the bottleneck on nvidia cards for dx12 performance. Also once the next gen cards come out it will be better for MantleVR vs gameworksVR or whatever they will call the nvidia version.
explicit multi-GPU, after DX12 becomes popular, could become exceedingly popular. It's strange now because it's extremely hard to do, but being able to use two different cards means you can reap the benefits of both vendors.
It means that Nvidia users can purchase an AMD card and see better results with cross GPU support, rather then buying another Nvidia card. I will be doing that... and hopefully be able to still use Shadowplay! :D
Amd ACE has been around for a very long time. That is quite the headstart on nvidia... shit happens. My fury kicks ashes of the singularities ass, and I don't see any response from nvidia. Probably won't until they have a hardware level answer.
+Argoon1981 That what fanboyism does man... Nvidia doesn't even have to try, and their market dominance does the rest. The only reason the hardware is even faster at this point is solely due to the fact nvidia gets more machine time from developers when optimizing, that and gameworks. AMD has more powerful hardware technically speaking.
I think if developers feel too subjugated by nvidia, they will not use it. Developers are getting really tired of nvidia fucking up their games if they run better on amd.
+Richard Smith Unfortunately i'm afraid game developers will avoid using asynchronous compute because only AMD truly benefits from it now and Nvidia has the bigger market, so as always, the bigger market is the lower comum denominator.
GOD BLESS YOU SIR! I have been after a review of this magnitude for ages now. I have the option to get a 380x to pair with my 970 and am totally thrilled to see that cards such as these work together!
Bless you, BLESS YOU SIR!
NVIDIA is too far behind regarding DX 12 support. I don't see them even remotely attempt to catch up for at least 6 months and even then updated driver support for DX 12 is not just the only problem they have. The basic structure of their video graphics cards is geared to more limited threading compared to AMD. NVIDIA will try to market their hardware to gaming software they previously had an advantage in bench marking but those numbers will not hold up either. They will even try to simply re-issue previous games with enhanced graphics quality and those games will have problems most likely due to rendering differences from their own coding changes and not because of DX 12 problems or A synchronous processing. I would be very surprised if any of their pre DX 12 hardware performs well in DX 12 even with any type of drivers they issue because I suspect they purposely make their own cards under perform in the long run to sell their newest hardware.
"Lack of driver support", no. It's been 6 months since they said that and, for a group that releases a lot of drivers and very fast (Game Ready) that is really weird isn't it? It's like they can't do anything because Maxwell is crap for dx12 and are just waiting to release the new cards that actually are dx12.
New tests with the AOTS latest update put the Fury X > GTX 980Ti by about 13fps in 1440p. 380X getting same performance as 970. 390X beating the 980Ti in some cases.
"Wouldnt buy a fury x and an nvidia card" what if i want better physx?, i have a 960, and i have a 660TI dedicated to physx, and in some games i get a 40% boost in frame rate with the same settings, and the 660TI is the bottleneck at 99% usage. Sure someone is probably not going to go out and buy a FuryX and a 980TI, but they might want to get a 390X, and a 950 for physx
What i want to know is if the explicit shared GPU function effectively scales your vRAM and frame buffer, would be very intersted to have a quad 1080p video wall powered by 960/950s and games scaled across them at an effective resolution of 3840x2160p, and then independent on the desktop.
+Tomislav Mladenov That is the common consensus. If you look at RedGamingTech they do a few videos on the subject.(don't let the name fool you they cover Nvidia a lot also) Maxwell doesn't support Async on a hardware level so They would have to use Drivers to work around it if they even can. It is also believed that Pascal won't fair much better in dx12 but we won't know that until the new line releases.
+VaultDad Well yeah you're going to get better performance with crossfire 390x's they are the more powerful card. No different than you're going to get better performance with sli 980s vs a 980+970. This video was nothing more than a demonstration that this practice can even be done across the different companies, and I doubt it has much deeper meaning than that.
ok, so I will ask.... Is there a legit reason to combine a 390x and a 970? Or would I get a superior experience with my current set up of crossfire 390x? That is the question that this video creates, but does not answer, And yes I did watch this video, A month ago when I made this comment. I want to know would I see a benefit in dx12 by adding a Nvidia card to my system, say for Physx? That is all, and you have not answered that. nor have they, the people who created the question.
So then am I to assume you are conceding that there is no benefit to pairing a 970 with a 390x? A pair of 390x in crossfire would be a superior option? all the 970 would do is add another layer of problems with no noticeable gains?
+VaultDad I already explained. SLI 970s: "Here are the results you would get with two cards of the same category" then slifire it with a more powerful 390x to show the contrast of what you get with a card that's stronger paired with a weaker card.
+Gamers Nexus Neither do I, but I almost invested in two 390's or one 980 so went with the 980... I'd be curious how the 390's in Xfire would do against the SLI 970's... I could probably google it so no worries...
"lack of driver support"
they just made a driver update that RAISED the performance in DX12 a while ago. They desperately needed it because in some earlier tests they were SLOWER in DX12 over DX11.
Nvidia's strategy has always been really strong driver support instead of simply having really strong hardware; DX12 makes it harder to have a driver advantage.
Good explanation/demonstration of multiple disparate GPUs in AoS. I very much want to see a demonstration/benchmark of the benefits of discrete GPU plus iGPU use. I think virtually everyone nowadays has a CPU with an onboard iGPU and I've always been frustrated that for me it was sitting there doing nothing. Now that DX12 allows it to function in tandem with my graphics cards I'm very curious about how it will affect performance. Intel has put a lot of resources into developing the onboard graphics for the tablet and laptop market and soon I'll finally get to put it to use as well. Please do a review.
390x easily beating the 980 and allmost on paar with a 980ti and the fury (none x) taking the top... yeap AMD's old architecture was ahead of it's time implementing directx 12 features on hardware level, unless NVİDİA doing some shady buisness with forcing gameNOTworks to the mayor games i see only an angry mob of Nvidia owners. Can't fix something with drivers what is needed on a hardware level.
P.S. 380x allmost matches the 970.. just crazy
+danjal07 ive seen more issues from nvidia users then amd migrating to 10 sounds like you had issues ie didnt go to amds site and install the proper crimson drivers like they stated im running a 390x absolutely love it have little issues with it under windows 10 :)
+DanusMax agreed id swap a 970 for a 390x that card is defective at launch what aggravates me is people defending it no the card has 512 megs of its ram crippled that isnt a good thing at all and there is no reason for it other then poor binning
Will you be doing any test for different GPUs from the same brand? For example, the 980 and 760 or something? If you mentioned whether you'll be doing that content, my bad - wasn't paying attention throughout the entire video.
