AMD confirms feature-level 12_0 for GCN maximum

[Spjut]

Game studios will obviously want to target as many GPUs as possible, whereas AMD and Nvidia will want to push their latest GPUs.
Nvidia will want to focus on feature level 12_1, probably even at the expense of its older GPUs, whereas AMD will want 12_0.

Having various Kepler GPUs in my PCs, I wonder how badly feature level 11_0 will hurt it. I'd guess Battlefront will be the first test.

Is DX cap viewer delivered by nvidia?

Anyway, we all see how GCN is maturing and kepler got old instantly after maxwell release. featurelevelwhatever doesn't matter when it comes to futureproofing. GCN is in consoles, GCN is mantle, GCN is Vulcan, GCN is DX12... everyone targets GCN.

And some game developers on this very forum thing that GCN is much future looking architecture, even compared to maxwell.

 

[ShintaiDK]

I have no idea what this means.

It means GCN 1.0 doesnt support DX12 featurelist and wont do. You need GCN 1.1, 1.2, Maxwellv2 or Skylake IGP for that.

Its delivered by Microsoft as part of the DirectX SDK.

Hell, even Matt Pettineo the Lead Graphics Programmer for Ready at Dawn which just shipped a technical showcase such as The Order: 1886 seems to be on the same page as I am as he too thinks that Southern Islands support tier 2 of tiled resources ...

The conclusion is this ...

Tiled Resources Tier 2 = AMD_sparse_texture ...

AMD_sparse_texture is already supported on ALL Southern Islands GPU so they MUST be already capable of tiled resources tier 2 ...

ShintaiDK can keep insisting misinformation as he likes since it's pretty obvious I'm the one with the overwhelming evidence here ...

I'll take AMD PR and a high end graphics programmers thought's over a dated pic of DX Caps Viewer ...

 

[ShintaiDK]

You can take a fresh dxcapsviewer today of both Windows 8.1 and Windows 10 with the latest drivers. Doesnt change the fact that GCN 1.0 is DX11.1 only. And all the DX games run will say its DX11.1, because thats what the DirectX API reports.

Computerbase updated their article and confirms GCN 1.0 can't support Feature Level 12_0. See "Update 05.06.2015" section.

 

[ShintaiDK]

Yes, i dont get why people argue against AMDs own facts.

 

[Glo.]

I wonder how many people who defended Nvidia for not fully supporting 11.1 are now criticizing AMD for not fully supporting 12.1, or vice versa.

Its very possible that NVidia payed ME for locking DirectX 12.1 feature(S) for Nvidias architecture, for marketing purposes.

That is the reason why 12.1 is only on NVidia. Also 12.1 feature level In big scheme of things is meaningless as na addition to 12.0.

Not this again.....this must go back almost 15 years when Radeon 8500 had DX8.1 and GeForce 3 only had DX8.0. This stuff doesn't matter like DX10.1 didn't really matter over DX10. By the time games actually use some extended features of DX12.1 over DX12.0, most people on this site will have upgraded to Pascal and 14nm/16nm GPUs. It's the same story for the last 15 years. The GPU power and VRAM bottlenecks will creep up far quicker than the minor differences between DX12 versions. Ever try playing DX9 games with a first generation DX9 cards? GeForce 5 did support it but it was worthless for DX9 games. 9700/9800 series were miles faster of course over GeForce 5 but who really cares because people moves on to GeForce 6-7 and X800/1800/1900 series anyway because DX9 games became to demanding for 1st generation of DX9 GPUs.

Yup. We go through this pissing match every time a new version of DX comes out. Who cares. By the time games utilize DX12 these cards will be in the dust bin of history.

Or the far more logical thing is you just make up FUD.

But I dont see why you have to. Consoles are DX12.0 so any DX12.1 support will be rather minimal.

Because there are TONS of people here including you who can't read the specs ...

No ones arguing the facts ...

There are just people out in the world who is not educated enough to grasp the subject at hand ...

Well if you dont understand it you should just listen to what AMD says. Either via their PR or via their drivers.

Hi Guys

Is my video card supports the Directx 12 , Means Which is one of the features supported ?

Do I need my feet Graphic card for future Games to update.

My VGA: R9 280X (GCN1.0)

Which insider from AMD claimed that ? The PR team ? Robert Hallock ?

If they don't list names or something they'll be labelled shills for Nvidia soon enough ...

 

[Glo.]

Why would I post FUD about platform that I dont care at all, but happened to know something about?

I dont play on consoles, and on Windows, only on OSX. So why would I bother about it.

Of course, I agree with you that if i dont have a source, (or I dont want to show it) I should post it only as a rumor, so take it only that way.

You card supports the DirectX12 API, but the features its capable of is only DirectX11.1 level. It shouldnt be a problem until DirectX 12 featurelist becomes the minimum.

For those of you who don't know Google Translate exists,

In summary, no 12_1 for GCN. Not only did a person of authority from AMD confirm it, but also AMD sourgraped about it much like NVIDIA did about 11_1 for Kepler.

 

[ThatBuzzkiller]

Yeap, I'm done here ...

No arguing when almost everyone is in the dark ...

The entire PC tech community is severely lacking in programmers and engineers ...

Twitter, gamedev, and some others are where it's at ...

No use in trying convince when people can't read the specs or anything extremely technical in this case ...

I can tell you didn't even read the article. I can't read German, but can see one name you mentioned:

"ComputerBase hat in einem persönlichen Gespräch mit Robert Hallock, Head of Global Technical Marketing bei AMD, in Erfahrungen bringen können, dass Graphics Core Next in den bisher verfügbaren Varianten DirectX 12 auch mit dem Feature-Level 12_0 unterstützt"

I can't read German either but for Google translate I got "H has in an interview with Robert Hallock, Head of Global Technical Marketing at AMD, can bring in experiences that Graphics Core Next supports in the previously available versions DirectX 12 with the feature level 12_0"

Which roughly translates to "GCN supports feature level 12_0" so WHERE are people getting that "previous iterations of GCN DOESN'T support feature level 12_0" ...

He is saying that GCN supports DX12 even with feature level 12_0 aka they don't need 12_1 to support DX12.

OK sooo "GCN supports feature level 12_0" =/= "previous GCN iterations does not support feature level 12_0" ...

Got it and thanks ...

Let this be a lesson to those who pushed an agenda for those to READ BETTER next time ...

 

[Noctifer616]

A correct translation would be:

ComputerBase has in a personal conversation with Robert Hallock, Head of Global Technical Marketing at AMD, learned that GCN with its currently available variations supports DX12 even with feature level 12_0.

My German is a bit rusty since I don't use it often but that translations should do (certainly better than google translate).

Hmm, so "currently available variations" which means that ALL GCN GPUs support a minimum feature level of 12_0 since Southern Islands IS currently available ...

Thanks for helping me set that I am on the right track with what AMD PR and high end AAA graphics programmers kept insinuating ...

People who kept insisting that Southern Islands was only capable of feature level 11_1 have some mighty explaining in how they were DEAD wrong ...
