SLI is manageable, if you are willing to tweak things to avoid the microstutter. Or maybe your FPS is high enough that you'll never notice it. For myself, it's not worth dealing with... I just always get the fastest single card I can afford nowadays. So to me, the Titan looks like a better buy than 2x1080 today.

If Nvidia/AMD can somehow come up with a solution that fixes it completely then I'd be fine with going multi-GPU again. I remember reading that SFR rendering was not prone to microstutter at the cost of scaling. I'd prefer that, but there's probably a reluctance to do so as benchmarks would look less impressive then.

DX12 will address this, the problem is the way DX11 works. Vulkan will fix this too.

Yes, DX12 proper multi-adapter support will probably actually fix micro-stutter. I will be very happy once DX12 multi-GPU support is normal but I will buy the second GPU after it happens. thumb.gif

I had SLI Titans but I swapped to a single 980 Ti as soon as I could, it was a bit slower in raw FPS but it was a better experiance in everything I was playing at the time (Tomb Raider 2013 with G-sync wasn't good with SLI but it was great with a single GPU, I believe this was improved later with some patches/drivers). Fallout's engine always feels bad with SLI too.

I think how well SLI works for you really depends on what games you play but also, if there is increased frame time variation, it bothers some more than others.

SLI sucks and blows. I have never been satisfied with a multi-gpu solution. Titan X SLI was the last for me, even with high frames and gsync displays it still did not deliver as smooth an experience as one card with the games I like to play.

I had the unfortunate experience of stutter with a GTX 590 and it was unbearable. I returned it and later bought a 580 and it was a much smoother experience despite being much slower. That was 5 years ago and I'm still surprised they haven't addressed this issue.

The reason we have the Titan XP with 3584 cores is GP102 yield and binning. They didn't get a sufficient yield of GP102 chips with all 3840 cuda cores working. So to produce their Titan XP, they reduced their required number of working cores to 3584.

Competition from AMD is not the factor that will give us the 1080Ti. Yield and binning is. If they are getting large quantities of GP102 chips with more than 2560 operational cuda cores, but less than the 3584 the Titan XP has, than rather than have them sitting there going to waste, they'll package them up into a new GPU and call it the 1080TI. They'll drop the price of the regular 1080 by $50 to $100 and slot the 1080Ti in at around the $800 price point.

This is a somewhat simplistic explanation to the binning process, because it's more than just about the number of working cores. It has to hold a certain clock speed and they need minimum number of other units on the chip to come out viable. But you get the idea.

They may possibly be getting some perfect GP102's with all 3840 cores working. If there are sufficient numbers, we could see a limited edition Titan XP Black or something down the line. But I wouldn't bank on it.

What nonsense is this? Titan and quadro has been sharing sharing same specs all along since titan existence. This may not apply for first titan but at least they have same amt of memory. Now that the quadro only get 24gb and 3840 cores. Obviously that overprice gpu is the 1080 ti. Go look back in history and stop all these justification for pricing nonsense

Great. Thanks. You've been helpful there. That explains what happens to the perfect GP102's. So to review:
  • The best GP102s (3840 cuda cores) get used for Quadro P6000.
  • Second best GP102s (3584 cuda cores) get used for Titan XP.
  • Third best GP102s (guessing 3072 cuda cores) will eventually be used for the prospective 1080 Ti.

And there WON'T be any kind of limited edition Titan positioned above the XP.

It all fits. Great.

Haven't dropped to a single GPU since the GTX 260 and I can't go back.

So, with my quad 690s (only have a single 690 now, and I no longer play with it since I have other cards that I can use now), I had fewer issues than with my Tri sli and 4 way sli Titans.
I used to swear by sli at one point in time, but I have had enough stuttering issues with Far cry 3, Far cry 4, Witcher 3, skyrim, for me to discontinue using Sli. I don't know if these issues were only related to Tri and 4 way sli, or game engine related, but all I can say is that my single Fury has been pretty smooth in a number of games, including Witcher 3. I must qualify the above by stating that I have never tried a single desktop Nvidia or two way desktop Nvidia sli set up for gaming (my 780 Ti was purchased for benching, and now serves a different tertiary purpose).

I just take a holistic forward looking approach to sli support by Nvidia; If it was hard for Nvidia to provide optimized sli support for Gameworks sponsored DX 11 games , it would be even more uneconomical to spend developer resources on dx12 based sli configurations .

I've always felt ~40FPS on a single GPU feels about the same as 60FPS on a SLI setup. I'm very sensitive to frame times.

Since I tend to game with VSYNC on, SLI does not feel smooth at 60FPS to me. I feel like I am constantly gaming at 40-50FPS (depending on title) even though my FPS is a steady 60.

Some people claim they don't have that problem, but I think it's more they aren't sensitive to it and/or are use to it.

Keyword is alpha there. If a 1080 is getting 41 min, I think the Titan X will achieve 60 at max when the game is actually optimized.

I still believe it is an issue only certain people are sensitive to. I am not sure it can be fixed for those people. The ones that arent sensitive to it should thank their lucky stars.

Can't believe there is so little new info on the Titan XP this thread has turned into a multi-gpu discussion.
