I am a pc gamer/pc enthusiast.
I like AMD but I dont like dual gpu solutions crossfire (or the one from the green team). I think both are unstable (especially when you are hooking up a multi monitor setup).
I have seen my fair share of crossfire builds fail. I pointed and laughed at my friends who wasted their hard earned $ on it.
Besides unstablity of drivers, to me it feels more like a design flaw.
I dont like the way work is divided between gfx cards and how there is a "primary" card that all monitors plug into...

Now let me say this 'I just love eyefinity...' I will never go back to one monitor gaming again.
Problem is that one cant do 4k eyefinity with a single gpu (atleast with gpus in the market right now) therefore I need multiple GPUs...
Now, I want multiple gpus but I dont want crossfire?
As a result for my next build I am planning (hoping for) what I call a dedicated gpu eyefinity solution.
3x1 4k monitors with 3 dedicated amd gfx cards.

My question is... will eyefinity support three 4k monitors in 3x1 configuration plugged (using displayport) into 3 seprate AMD gfx cards (no crossfire)?
My expectation with "Dedicated GPU Eyefinity" solution is that gfx workload for each monitor in the eyefinity group will be managed by its own dedicated gfx card its plugged into, there by eliminating the need for crossfire 'witchcraft'.
I think that this is a proven approach in technology... performance and stability through simplicity...:cool:
In future I am planning to mostly play Mantle based Games not sure if that is relavant to this question.

PS: incase this is not possible with current drivers/games I hope AMD is taking notes...:D


Your input and opinions are appreciated!

No, it will not support it. To use eyefinity they all must be plugged into one single card to display it. You must use crossfire in order to get the added support from the other GPU cards while gaming.
 
The only way that would work would be if a game was coded to allow for multiple discrete monitors. Maybe some flight simulators?

Eyefinity/NV Surround work because they present the game with a single virtual screen for the game to render and the cards/drivers handle the rest.
 
What you are proposing is not a very good solution. The reason the systems work the way they do is that you are displaying a single image across three separate monitors. What you are suggesting is that you display 3 separate images, but how do you keep them sync'd? Currently that is why you have Xfire and SLI solutions done the way they are. The primary card is responsible for maintaining the full image, it sends jobs down to the secondary cards to process, then they report back to the main card that puts it all together so you get the single large image. It is more efficient than trying to get 3 different cards producing three different images all sync'd up at the same time to show the proper full picture.
 
NoOther,
I think you have done the best job at explaining what is going on so I do have to give you special credit. However I want you to think about crossfire/sli technologies once again.
You see these technologies were developed before multi-monitor gaming was even a thing. These were developed for for conventional one monitor gaming designed to push frame rates up on ONE monitor and enable HD gaming at the time.
Obviously, when you have one monitor with one DVI connector, you want ONE GPU as primary to "handle" and "stitch" the work done by various gpus. Now with multimonitor pc gaming entering mainstream why can’t we rethink our multigpu approach? :cool:

I do thank you all for your input so far. :D

From the comments above it looks like this is a 3 part engineering problem:
1. Eyefinity monitors all need to be plugged into the same card for "sync" reasons.
2. Video Games themselves are not written to use multiple individual gpus and sli/crossfire wizardry will be required until games learn how to do that (they probably won’t).
3. Eyefinity can’t do "virtual display emulation" when monitors are plugged into different cards.
I think guys n gals at AMD are innovative enough to figure it out but atleast for now I kind of understand where the limitations lie.
IMO for problem 1 I think it might be possible to repurpose the existing crossfire bridge connections for Eyefinity to keep the images displayed by the cards in sync.
And for problem 2 I think it might be possible to enable multi gpu support at the API level (direct x, openGL, Mantle) without having to modify the games themselves.
And for problem 3 I think eyefinity might just need a simple patch to allow "virtual display emulation" across monitors connected to different cards once problem 1 is worked out.
I know that this is likely all wishful thinking. :p

Your input and opinions are appreciated.

1. It's not to sync, it's how the drivers are written.
nVidia Surround uses multiple inputs on different cards. Drivers.
2. They could do that, but they won't. The drivers could do that, but they won't.
3. It already exists in the form of software. Search for virtual monitor software or something of that nature.
4. What in the fuck....?

That is not really true. There have been multi-monitor setups for a long time, not so much for gaming but for other applications. The technologies were developed using the same theory, you give various cards different parts of the picture to compute, then you put the full picture together. The number of monitors isn't the issue at all, its the single picture aspect of it. Whether you have 1 monitor, 3 monitors or 21 monitors, its all the same single picture. That is where your limitation is, you have to keep that single picture synchronized which is why you always have a master GPU to handle that.

Also there is nothing wrong with having multiple DVI connectors on one GPU. Separating out the DVI connectors to other GPUs does not give you anything extra. You are limited by the bandwidth of the DVI spec, not really the card.

1. Not specifically true, it makes it easier. You have a master card for sync purposes, but they might be able to develop a system to spread that signal out other ports on other cards. The question though, is why would you do that? There isn't really much to gain from that and you introduce more engineering and complexity.
2. That isn't the way the system works. The game simply has graphics to compute, these aren't the same processes that get sent to a CPU, they are simple and are broken up by the GPU into smaller tasks to compute. That GPU can then separate the jobs and send some of them to other GPUs to help compute, which return the finished product to be put together by the master card. There is nothing really for the game to be programmed to do here. As for the API, not sure what you are getting at, there is already Multi-GPU support, that is what Xfire, SLI and other technologies are all about. If you are specifically wanting multi-GPU output support for a one card to one monitor scenario, they won't do it because it is inefficient as mentioned in the reply above.
3. As was mentioned by Master Pain, there are a number of software solutions for doing this already. The problem with doing these things through software is it is much slower, which is why AMD and Nvidia are using the systems they have now, they work far better for many applications.


If you look at it like this, how does distributed computing work? You have a lot of different systems connected together that help process a larger problem, but you still have a master system that collects and collates that data. You might have any number of people that use that system and get that information, but you still have a master system divvying that out. That doesn't mean that the master system is using all its own resources to display or send that information. You aren't losing any resources by having all your monitors connected to one card. All the processing is done by all the cards in the SLI/XFire setup. Only the divvying out and collating of the processes and putting together the final display is being done by the master card. The overhead isn't so large that it's breaking anything. They also aren't severely limited by the number of outputs you can use. There are many people with 5-9 displays being powered by these setups. Sure there are some limitations, but ultimately your main limitation is going to be the sheer size of the resolution, not really the outputs for the displays.
 
Thanks a bunch.

I conclude the only way to stay ahead of the curve is xfire/sli. I know I will have little patience for a crappy xfire set up. I cant have my games crapping out.... I will stick to 3 HD monitors eyefinity and single kickass card.

From what I have heard dual gpu cards are also xfire/sli. Are you suggesting xfire/sli is more stable in dual gpu cards vs building an xfire set up with separate single gpu cards on your own?

Yes, dual GPU cards are SLI/X-fire, they use a PLX chip on the PCB to do the pci-e work that would otherwise be done by your mobo/bridge. No, they are not "more stable" versus a configuration using discrete cards. However, for the goals you're targeting (3x 4K displays), x-fire/sli is what you need to be looking for. Even if you're willing to shell out for the highest of the high-end single card and then put it on water with a raging overclock, it's probably not going to cut the mustard :(
 
As I mentioned earlier I will stick with 3 x Full HD monitors 1920x1200 and single GPU card.

But I am curious to know as to why there are no proponents of xfire/sli here? Does any one believe that an xfire system can be as stable as a single gpu system? In addition to having stable drivers, does 'stability' of these dual gpu systems vary from game to game and other hardware factors? I have seen xfire/sli "certified" boards/ram/psus in the market. From what I have read online, the topic of xfire stability seems to be very subjective, with too many variables.

Sorry, I missed the additional info on your display config. I just remembered your op :)

I have very little experience with X-fire configurations and despite the obvious similarities it's my understanding that (at least in the past) that X-fire has some issues with things like micro-stutter that are possibly more prominent than in SLI configurations. I would classify myself as a proponent of SLI. The sheer insane amount of power that you get from dual cards (or more :p ) when you're dealing with a game that scales well means that your game experience can go from really good to holy tap-dancing shizzle screws this is amaze-balls. Those things being said, I still consider an extremely powerful single card superior in some regards. Having dealt with the miscellaneous oddities that can crop up with SLI for so many years, using my 780 (outside of a slight bummer RMA situation) has seemed like nothing but smooth sailing.

I guess I would classify SLI/X-fire thusly: If you want the absolute max out of your gaming, and you're playing what's new right now, then multiple cards at any given time is the way to go. If your gaming "scope" is somewhat limited in that you're very application focused (like the SC2, DOTA2, or CS:GO crowd for instance) or you're working your way through an extended Steam back-list of older gaming titles, then you probably only need a single good card even if you're doing it up with multiple displays (outside of 4k at this point anyway).

To add: I pretty much fall into the latter of the above situations right now, so I'm thrilled with the performance of the single 780. However, if some new-gen Elder Scrolls single player game gets dropped, I will probably go right back to SLI for that if the 780 doesn't cut it.

I have a similar build.
3 1920x1080 monitors with tri 680s.
yes, there are problems. but these issues are minor and are more desktop related than gaming.
the only time i have problems with games is on the developer end when they break sli.
for instance when bf4 broke sli for a week.
but, all you do is play on a single monitor with a single card until the issue is fixed.

i really think people blow the xfire/sli stability out of proportion.
yes, xfire/sli will never be as smooth as single card gaming, but when running a setup such as eyefinity or surround what other choice do you have?

there is no way you can play triple a titles such as bf4, on surround or eyefinity with just one card. at least not at a playable fps, imo.
through my experience, three cards is the sweet spot. i had two 680s and the third made all the difference.

as far as 4k surround goes, i dont think this is realistic even with a quad setup.
its hard enough to push a single 4k monitor let alone three.

There are many proponents here of both Xfire and SLI. Personally I have used both and have not had any major issues with them. Probably a lot of people just feel you are trolling with so much hate towards those setups. And people are giving you information and advice based on what you asked. You seem to have made it abundantly clear over and over that you hate Xfire and SLI, so why would anyone want to suggest it or talk its merits with you?
 
My first surround system was (2) GTX 480s with the giant Arctic 3 slot air coolers. It worked pretty good for Bad Company 2.

I then went to a pair of 680s when they came out and last year I upgraded to a pair of 780s.

I have no idea what you're talking about when you harp on the problems of SLI. I've heard Xfire has issue, but I don't know much about it first hand so I don't comment on it.

My best guess about people having issues with microstutter is that they don't know what they're doing and/or they made some very poor choices when they put their system together.

I try to build for performance and I don't cut corners and I've never had a problem with "microstutter" in any game, ever.

Personally, I don't see any reason to run a 4k screen in a game, let alone in Surround/Eyefinity. The purpose of a three screen system is immersion and in my opinion, smoothness and high frame rates contribute far more to immersion than pixel density or resolution (within reason).

The part of the eye that detects motion does not not detect detail. We all like to see the eye candy, but when you're trying to play soldier or whatever, you need to engage the motion detecting aspect of your vision.

In my opinion, anyone who proposes 4k Surround with anything less than 4 over clocked, water cooled top tier cards is fundamentally unserious or uninformed.

Dunno about you, but I've been doing just fine driving 5760x1200 with a single GTX 780 :p

I'd rather drop a setting or two than deal with all the headaches associated with SLI / Crossfire. I'm not just talking about software issues, either. It's pretty much impossible to keep a multi-GPU system within noise limits that I find even remotely acceptable.

I'm afraid your anecdotes are directly contradicted by observable and repeatable evidence. However, when using some of the most powerful GPUs available the problem is largely alleviated. This has nothing to do with "poor choices" when someone is putting together their system (unless by 'poor' you simply mean 'not enough money'). You just happen to be among those fortunate enough to not notice and/or not be bothered by microstutter when it occurs ;)

yes, im the opposite.
i like playing on high settings with a constant 65fps in bf4.

the weird thing is that my system is quieter now with three cards then it was with just two.:confused:

You asked what other choice there was, not what was preferable :rolleyes:

And as for BF4, "high" settings are do-able at 5760x1200 on a single card. Maxing every single slider isn't going to happen, but high settings are quite do-able. Better still, I don't have to listen to a pile of fans blaring away while I game, that alone is worth it (I'm sorry, but I've never heard a multi-card setup that I would want to sit next to, they're all too loud).

If you can live with FXAA (rather than insane super-sampling settings) the game also becomes extremely easy to run :p

Kind of funny since I have been running multi-card setups for years and not had the ultra loud scenario you picture. They are hardly ever much louder than a single GPU, unless I am maxing out the cards with a benchmark. But noise is pretty subjective, what bothers some does not always bother others.
 
Personally I think you are irrationally negative towards CrossFire/SLI (multi-GPU acceleration) for gaming. When setup properly, it works just fine. It is also the only way to get optimal performance on 4K, especially multiple 4K.
 
I am glad to see some very confident proponents of the multiGPU solutions here and needless to say it is a popular solution in the gaming / enthusiast community.

As for me - Professionally I work on mission critical IT systems that are expected to run for 5 years without fail and my definition of stability is a little different and naturally expectations are higher.

Looks like multiGPU works but it is not exactly convenient enough for everyone.
Besides stability few other factors mentioned in posts above are:
- Cheaper cards have more issues in multigpu configurations
- Heat from multiple cards is harder to manage (may need air conditioning)
- Noise is harder to manage
- Mistakes and poor choices during builds lead to issues
- Some people are more sensitive to flaws such as Micro Stutter
- Nvidia has had more success with their multi gpu solution
- Time consuming?
- Slightly lower detail settings in games is a easier trade off for most people as motion (fps) is more relevant than detail when it comes to gaming.

I'm not "picturing" anything. I've tried multi-card before, it's never quiet enough. I'm not sure how you think two fans could ever be as quiet as one fan, especially when adding a second card will increase ambient temps (thus forcing both fans to run marginally faster across the board).

Glad that you can stand it, but I certainly can't. Trying to keep one high-end card quiet is already bad enough, two is a total nightmare scenario.

I have worked with mission critical systems for my entire career. What that has taught me, is that my home gaming system is simply not mission critical.

As for your list, most of the things you mentioned seem to be nitpicking and almost all of it is fixed with proper installation and setup. The first comment about cheaper cards, is not really relevant. Cheaper cards are cheaper cards and may have problems on their own. I have had zero issues cooling my multi-gpu setups, that is just a matter of using proper air flow. I have had very few issues with noise, which I have mentioned before is subjective so mileage may vary on that one. I have experience micro stutter here and there, but often times that can be fixed with some simple tweaks. Time consuming is also a little bit relative, how much time is too much time? Takes me maybe a few hours max dedicated specifically to the multi-gpu setup to get it all working (installation, heat/noise cancellation, drivers, settings, etc.). As for the motion, that is neither here nor there for single vs multi. In fact, that works against you since you are talking about doing a single GPU solution for surround gaming. You will automatically be sacrificing both detail and FPS. Multi-GPU solutions will only help enhance your FPS. Remember there are a lot of people doing XFire/SLI for improved performance on single monitors as well, its not just a solution for surround gaming.

All that said, obviously its a hobby. Not everyone requires surround gaming, or enhanced FPS/Details. Some people are content just to use a single card and that works for them. No reason to try and sell them something they don't need or care about.

The OP was talking about microstutter resulting from running multiple GPUs - something I say I have not seen, and to disprove that, you point to a review using Metro Last Light?

Did you even read it?

article you didn't seem to read very carefully said:
On this 30 Second run the graphics cards all show massive spikes. and thus indicate stutters, we can confirm these as visible on screen. This happens with ALL cards tested at any resolutions, so it is A4 game-engine or system related.
Click to expand...

PCPer did some great work researching microstutter with their FCAT frame thingy - from what I saw when it first came out, it seemed to be a much larger problem with AMD and their frame scheduler - which they have apparently improved since then, but I don't follow AMD much.

See: http://www.pcper.com/reviews/Graphi...ils-Capture-based-Graphics-Performance-Test-2

And generally: http://www.pcper.com/category/tags/microstutter

For the OP and others worried about heat and noise, I run two 780s in an mATX case - they stay within temp spec and the noise is pretty mild.

When I said I suspect some people make mistakes and poor choices, this is the type of decision I'm referring to:
1. Using a low end motherboard or running a strange configuration (16x + 4x)
2. Cutting corners on your power supply
3. Making poor choices when it comes to your case and cooling
4. Using more lower end cards when you could have used fewer high end cards
5. Poor CPU choices including unstable overclocks

I'm not "insensitive" to stutter or hitches in a game - the other night I was backing up my NAS to my PC and was getting just a little bit of hitching in BF4 but it was driving me crazy.

I wish I was less sensitive - I've seen good players use systems I would consider unworkable - I usually run multi player games on medium settings to ensure smooth/high frame rates. Everyone has a bias, but I would choose 100+fps on medium over a solid 60fps on high settings. The choice is usually not that stark, but I do like fast more than pretty.

:eek: *shrug* apparently I picked a bad example. Switch over to another part of the same set of FCAT specific reviews and the same thing I said before still holds true. I'm not decrying the use of multi-gpu as a result of the issue, and it's great that your config isn't causing apparent issues, but OP asked about microstutter with multi-GPU. It does exist, but it is alleviated for the most part on high-end gear. It's also definitely been more prominent with AMD's multi-card solution vs NV's but it's not like it's not there at all in an NV config.

Sorry I didn't make it more apparent about the "poor choices" bit that I was being tongue in cheek :p I didn't really consider it from the actual practical level you did ;)

It's also definitely been more prominent with AMD's multi-card solution vs NV's but it's not like it's not there at all in an NV config.

Sorry I didn't make it more apparent about the "poor choices" bit that I was being tongue in cheek :p I didn't really consider it from the actual practical level you did ;)
