Possible 100% scaling with dual GPU?

@LinusTech @Slick @Whaler_99

Can we have a "Misinformation" tag/upvote ??
Shit like what the poster above posted, which is taken out of context only to tarnish a brand due to personal vendetta is not helpful to other community members. Be it old or new.

 

@The Benjamins already showed and prooved that @zMeul was wrong. Yet the above poster keeps tarnishing this thread with his personal hatred.

That is a form of downvoting and I'm pretty sure it would be heavily missused. 

That and people thinking they are right branding the real corrct answers as wrong. 

The ability to google properly is a skill of its own.

hello!

is it me you're looking for?

Fully maxed out early 2017 Dell XPS 15, GTX 1050 4GB, 7700HQ, 1TB nvme SSD, 32GB RAM, 4k display. 97Whr battery :x 
Dell was having a $600 off sale for the fully specced out model, so I decided to get it :P

 

-Crapbook

Fully specced out early 2013 Macbook "pro" with gt 650m and constant 105c temperature on the CPU (GPU is 80-90C) when doing anything intensive...

A 2013 laptop with a regular sized battery still has better battery life than a 2017 laptop with a massive battery! I think this is a testament to apple's ability at making laptops, or maybe how little CPU technology has improved even 4+ years later (at least, until the recent introduction of 15W 4 core CPUs). Anyway, I'm never going to get a 35W CPU laptop again unless battery technology becomes ~5x better than as it is in 2018.

Apple knows how to make proper consumer-grade laptops (they don't know how to make pro laptops though). I guess this mostly software power efficiency related, but getting a mac makes perfect sense if you want a portable/powerful laptop that can do anything you want it to with great battery life.

then they can make such a button only availible to use with @zMeuls posts. as 85% is biased vendetta filled lies. Intentional so

True. Imagine it as a next level escalation with dozens complaining that they were downvoted. As in new threads. That's how I imagine it.

Not to offend anyone, but most people here are sub 18 years old (if not younger) and many of those are fully addicted to post/upvote ratio. Call it the FB generation if you want. People running this forum probably don't want have to deal with anything related to that. I know sites like Reddit have it, and that gets pretty nasty sometimes.

TBH I don't get the big deal about this agree, informative, funny and thumbs up.

I would not really have a problem with such a downvote or whatever button, because if you comment on something, then you better have facts behind your statement, that you can just link if someone asks. Sure all the fanboys will abuse the living shit out of such a button, but then it would also be easy to see who is a fanboy.

You and me both, I'm just stating how things would work imo. :P

That looks good. But is it an exception? Or will it be the norm?

I don't remember that but is that an AMD or Nvidia title? Saw it plastered on AMD website I guess it's a AMD title.

Personally, better buy a mid-high end instead of two low end and hope for the devs to do their job.

That's great, when it does it though, not always it will be, but yeah very nice. Depends on resolution, game and such sure.

What I find it exciting also is frame timing improvements with multi GPUs too.

If you would look at their video you will see it scales 100% at 1440p but not at 1080p. and AMD article states that.

DX12 more than likely is setup to fully load one GPU then the next so @ 1080p the full compute power of 2 GPUs is not needed. At 1440p it is needed and why better scaling is shown. The way DX12 assigns duties Asyc to different cores makes sense to this.The way DX12 renders graphics is not the same as DX11.

Honestly, mixing different brands graphics cards sounds like a compatibility / driver nightmare to me. Good luck trying to optimize  that.

 

Actually what I would be most interested in is somehow unlocking the ability to use the iGPU on the CPU in tandem with the graphics card. Right now the iGPU is seen mostly seen as a useless afterthought by most gamers, but that would be a gamechanger.

DX12 is the driver that controls the cards work load not AMD/Nivida driver

ya, it could also be that at 1080p the game is too CPU bond but at 1440p it becomes fully GPU bond so it has a chance to scale. I was just pointing out that he missed that the res was different.

pretty shure the dedicated async hardware in the polaris chips is doing some good work getting rid of some of the overhead ,

combine that w/ dx12/vulcan wich take advantage of that and there you go , it only took almost 20 years to fix that issue :P

That has partially been made already: AMD APUs can work in "Dual Graphics" mode together with a discrete GPU.

I don't think it can change the fact that the iGPU is a useless afterthought for gamers, unless they can game on the iGPU alone :P

Well who knows. To be honest I'm not sure what kind of performance it could bring? But with the latest iGPUs being somewhat capable on their own you'd think there's at least some capability there to be tapped in to. Even if the difference is just marginal, it's nice to longer see that piece of silicon go to waste.

Any benchmarks around for that AMD wizardry?

The point is that iGPUs are still below entry level gaming dGPUs, so it's like adding a weak GPU to the mix. It's a bit like physix-dedicated GPUs: if the card is bad enough, it will hold you back, so you end up needing a powerful secondary GPU or you are better off with a single powerful card. Maybe one day we could have physx in powerful-enough iGPUs, but go see what Nvidia tells you about it :P 

Coming back to AMD dual graphics, it's mostly restricted to lower end GPUs that are not that far in specs form the iGPU, so the cards work in some form of hybrid crossfire. Hence, you are not going to find Radeon Fury + iGPU setups, only a limited range of cards (up to HD 7750 I believe, or some R7 equivalent).

 

For example, you can see this A10-7870K review with some benchmarks for single GPU and Dual Graphics. At some point I read some review on Dual Graphics alone, but I don't remember where :P There must be many, though, just google "Dual Graphics benchmark" and skip anyone meaning "dual GPU" ;)

Fair enough... just looked it up and it was all about potato-level cards... although performance seemed pretty good there.

I see your point with the PhysX parallels (where slow cards just ended up bottlenecking). But one can hope... Maybe you could divide the workload somehow and give the iGPU some easy stuff to work on so it can keep up while still lightening the load? Let it render skyboxes or something... those Intels must be named Skylake for a reason!

I remeber when that was a thing. Ah good times.

yes, The same day they forgot to restock the 390X and instead decided to move onwards with a new generation hardware that does not display this issue nearly as often as the last generation did..

Here is PCPer article

https://www.pcper.com/news/Graphics-Cards/DX12-Multi-GPU-scaling-and-running-Deus-Ex-Mankind-Divided

 

They got 55 for 1 and 87 for 2 of them at 1080p Very High

 

In the video they show the same results as AMD 100% scaling at 1440p on Very High

oh they definitely cherrypicked one superawesometotallygonnahappenallthetime stat as the headliner. no doubt.

Every company cherry picks stats. Also the way I see it is that 1080p was probably CPU bound so it was being held back and in 1440p and up it becomes GPU bound and that is when it can scale near perfectly.

Since the PS4 Pro is dual GPU, i guess AMD will push toward multiple GPU configuration. But damn thats some nice scaling :)

It's an AMD title, game was heavily pushed by AMD and AMD cards smashed nVIDIA on release.

 

Either way, I can only hope that this means that later as DX12 gets more and more adoption that it means that multi-gpu becomes more viable.
