AMD Radeon GFX & DirectX 12

[JediFragger]

They wrote Mantle, which large parts of DX12 is based on, and the overwhelming bulk of Vulkan (plus some spicy new stuff) is based on.

Yet they can't seem to write any ****ing drivers!!!!!!! If drivers were an API they'd be done by now

Thank you, couldn't remember the name.

This was all anyone was talking about a couple of years ago and it dropped off the face of the Earth seemingly.

Regarding RAM pooling, there is a glimmer of hope.

That is a PCIe switch with effective ~100GB/s b/w.

Really? Seems to me they have products in stock at ocuk and other etailers.

That aren't selling well which is why their market share is in free fall.

The way I'm reading it, with developers being in control of how multi-GPU performs, there won't be any need (or possibly even ability?) to write Crossfire profiles on AMD/Nvidia's side. It's all going to be in the hands of the developers.



As above, sounds like DX12 should bring the end of us moaning to AMD/Nvidia about multi-GPU not working on release day, instead we'll need to moan to Ubisoft/Dice/EA or the development studios themselves. That genuinely worries me and I really hope I'm wrong on this.



Yup. Aside from the graphics of GPUs (it is an AMD presentation, so fair enough) all the actual info is bipartisan and doesn't say it only applies to one side or the other.

Yes it sounds like the era of moaning to Matt for CF profile is going to end...

meh, split frame rendering has been around since the dawn of multi-gpu gaming, it didn't work well because the workload in different parts of the screen can be vastly different. Nothing has changed, it is just a fundamental limitation. Sure, with DX12 developers probably have better control rather than relying on the drivers to split the screen but that doesn't resolve the situation.

And the shared memory is nice and all except it only has the advantage of preventing duplication of a resource that will only be used by one of the GPUs, which basically never happens. texture and geometry etc are going to be needed on both GPUs because it will be far too slow exchanging resources between GPUs.
This works much better for compute applications.

Sweet sweet common sense.

AMD, the way its meant to be presented

The split frame rendering will be primarily a VR thing where the image is split across 2 screens, but otherwise the content of each image is the same.

I could swear that SFR was first implemented by 3DFX many years ago when they introduced SLI. I remember people saying they had issues whereby the cards would display half the frame at different times!

 

[Orangey]

They're not using SFR for VR, but they do have a technology to use 1 GPU per eye.

It was, the very first SLI implementations all used SFR, including Nvidia. As I said abive, it didn't work then and it wont work well now.

This chap should be fine with it !!!

Just been on a AMD webinar, when questioned about the lack of new GPU products in the recent past, they suggested that with such strong and regular driver updates they have not needed to keep refreshing products.

 

[ginjaninja]

how tight is the relationship between direct x version and gpu hardware design?

is the ley man to expect that relative comparable DX12 performance on latest gen cards will change significantly from DX11? or be much the same?

well with a question like that he was in a difficult position

 

[northwestdakota]

Yeah, thats true. They seemed to really want to back VR, so it could be interesting to see if/how the new cards will take advantage of VR. They confirmed new cards in the next few weeks, but then we knew that.

How was your trip to Bizarro World?

In it's own sad way, they were right. 290x came to fight against 780ti for starters. After time it has surpassed 780ti performance in most games, and even beating 980 in few games, which is very outstanding for such old card.

Games tend to run very well on AMD, their real problem is in crossfire profiles and games that are more cpu intensive.

But we see things differently, for us 290x isn't product to be desired, even despite it being' very good value for money. It's old, and old ain't sexy and shiny.

If that is the way you feel about the 290/x then you wont like the 390/x.

At least they have a sense of humour
h, they were serious. God help them.
