Although, the need for Tri-Crossfire to remove micro stutter is no longer needed thanks to Driver Improvements, took AMD over a decade and it was thanks to nVidia and an Enthusiast website to point it out.

It's too bad Nvidia will be removing 3/4-way SLI support on their upcoming GPUs ... 

I wonder if you can bypass that with DX12 multiadapter API or is that supposed to be handled in the drivers ? 

It's quite a surprising move, right? It makes me think that tweaking the drivers to work with more than 2 cards was too much work for so little users (even if most of them have their high end cards).

sigh... I'm still running a 660ti.
Go on. Laugh at me. I deserve it.

Really? Wow. That is going to seriously impact power user/enthusiast/professional rigs, AMD may be the only solution for those markets. (First time I have heard of this! But I typically focus on AMD/Intel anyway.)

And good point, but I don't think Vulkan/OpenGL has anything similar to that Direct X 12 feature though? All well and good for Direct X 12 to support it.

Possibly. I know that nVidia never had great scaling past 3 cards anyway, AMD's performance on 3 cards was pretty acceptable, but the main benefit was the elimination of Micro Stutter.

nVidia and AMD should open up control of GPU profiles, so that the community can build them, it would likely be faster and remove any development burden then.

Doesn't really matter if it does everything you want.

Isn't the SLI scaling going downhill anyway after the 2nd card or did they improve the multi gpu efficiency?

ATI Radeon HD 5850 owner here. The last gen of ATI branded cards.

And yes, you can laugh if you want, but it still serves me right (tho I'll upgrade to a Pascal or Polaris card).

It should surely be improved now, given the doubling of the bandwith on the 1080/1070, due to the HB SLI bridge.

The old SLI bridges will still work on the new cards. With a bit of luck, someone will make a comparison using the old and the new bridges to see how big is that improvement.

It has been going backwards, I think AMD just don't have the resources at the moment, they are busy re-organizing their GPU, CPU and APU teams, building Zen, Polaris, Vega, Navi plus new chipsets. (Please don't be rebadge 900 series which were rebadged 800 series which were rebadged 700 chipset series, AMD!)

Although, the need for Tri-Crossfire to remove micro stutter is no longer needed thanks to Driver Improvements, took AMD over a decade and it was thanks to nVidia and an Enthusiast website to point it out.

Thing is though its not just AMD that is sucking up the drivers for multi gpu scaling lately. I have friends that have SLI rigs and few games if any lately have supported it. I mean i know there has been a dearth of games that actually push hardware enough to need more than one high end GPU without 4k but for those of us that have taken that step it sure is annoying to not be able to use multi gpu setups because AMD and Nvidia have been lazy on the driver front.

The reason why SLI/CrossFire is so badly supported is that... it's not worth it. Not for you, for the companies. Check the Steam stats for the number of gamers using multiple GPUs - it's laughable. This makes investing money and working hours into perfecting the drivers not worth it. These engineers could be doing something that's actually beneficial. I guess that's what you get for being too ahead of the curve...



Wii U is a GCN 2 - I called it months before the release!

My Vita to-buy list: The Walking Dead, Persona 4 Golden, Need for Speed: Most Wanted, TearAway, Ys: Memories of Celceta, Muramasa: The Demon Blade, History: Legends of War, FIFA 13, Final Fantasy HD X, X-2, Worms Revolution Extreme, The Amazing Spiderman, Batman: Arkham Origins Blackgate - too many no-gaemz :/

My consoles: PS2 Slim, PS3 Slim 320 GB, PSV 32 GB, Wii, DSi.

Steam doesn't show statistics for systems with Multiple GPU's.

3DMark benchmarks with the GTX 1080 have been leaked

http://videocardz.com/59871/nvidia-geforce-gtx-1080-3dmark-firestrike-and-3dmark11-performance

While those synthetic benchmarks don't 100% translate into real life performance, it gives us a comparison point.

And there are also overclocked results, with the GTX 1080 running at 2114MHz: http://videocardz.com/59882/nvidia-geforce-gtx-1080-3dmark-overclocking-performance

So I'm reading a 1080 OC is about 30% stronger across the board compared to my 980ti OC. That's actually really impressive for a X04 Chip.

Still, I really want to wait for Big Pascal which should be quite an impressive boost even above that.
