Let's have a look at DirectX 12's Explicit GPU Functions. Want happens when a GTX 980Ti and a R9 Fury X work together?

Wow didn't think this would be allowed to work, I wonder how long until nvidia stop this
 
The benchmark will go live to the public tomorrow, it would be a big deal if Nvidia removed a feature.

All Nvidia would be doing by disabling the option would be to harm consumers, though they will try to spin it in a positive way for them.

if they remove the feature myself and plenty of other tech writers will flame them for it, as removing a feature is bad for consumers.

they have done it before though right? and Nvidia do genrally get away with a fair share of dodgy sh*t
 
they could force windows BSOD when it detects an AMD card installed side to the nvidia card.... and then blame amd for bad drivers...
 
Haha. Well its unlikely they will do that as they will be some rather dear legal repercussions. Then again I guess that didnt stop them before.

Wouldnt be the first time they invent a new feature that cripples AMD.

'Where is your god now?' LOL Now I see why you'd done that.

Nice read Mark.

I know they tried similar things with Lucids' Virtu a few years ago but I never got it to work completely. Some games were better, most didn't make use of it and some flat out refused to cooperate so the idea isn't out of left field, although Green and Red working together seems as likely as the end of the cold war to someone living in 1983.

Hopefully there are a lot of games that support it. Not necessarily for Nvidia + AMD but for multi GPU setups that aren't identical, EG 980 + 980ti or a 960+970 setup or even better and probably more likely a generational gap with similar specs so a 9 series can work with a similar 7 series without too much of a drop off in performance.

Also looking forward to features such as the VRAM being combined as a big pool instead of 'per card'

Interesting times.
 
Very very good read! IMO you're best one yet Mark:)
Was very informative and you tested basically every possible scenario with what you had to answer as many questions as you could. Keep it up:)

On the other hand, seems they have really optimized this game now. I was definitely not getting those results with my FuryX at 1080p(high settings)

this will be good if they can get it to work properly.

I wondered if the results are down to HBM on the first GPU but that isn't the case for the 380 so it must be drivers or some other AMD magic.
 
Thinking about the whole SLIFIre thing, it's possible to run a FreeSync of the AMD car and G-Sync of the Nvidia card at the same time, right? If one would go for the SLIFire solution in the feature, one could save big money by choosing a FreeSync monitor over a G-Sync one.

Probably not. I suspect you'll get a bunch of driver conflictions. Though personally I haven't tried it but if it is possible it probably won't be conveniently done
 
I'm just excited that we're finally moving away from 28nm ^_^

That maybe true, But i still think people are hyping this up way to much. It's one thing for AMD & Nvidia doing it that is to be expected.

For example what happens when Pascal & Polaris don't live up to what people are thinking that they were going to be, People are going to be very disappointed.

Remember AMD & Nvidia are always hyping up GPU's most of the time it's never that big of an improvement.

All valid points :)

I'm expecting a 20%+ performance increase, Quite conservative and realistic IMO.
