can someone native german can translate this for us? because from what I can understand: Bonaire,Tahiti, Pitcairn and Cape Verde are not DX 12_0 capable; Robert Hallock refused to comment
this is really big if true - extinction level event  :unsure:

DX12_0 mandatory features: Resource Binding Tier 2, Tiled Resources Tier 2 (Texture2D), Typed UAV Loads (additional formats)
 
​other thing that just popped into mind and would explain why MS had said numerous occasion that DX12 on XB1 would bring benefits but nothing exciting; why? the GPU in XB1 is based on Bonaire while the one in PS4 on Pitcairn

Nvidias GPUs based on the Maxwell 2.0 architecture will support DX12 on feature levels 12_0 and 12_1. Older GPUs only support 11_0. About AMD there has only been information so far that all GCN cards are capable of running the reduced overhead of DX12. Until now.
 
ComputerBase had a personal conversation with Robert Hallock, Head of Global Technical Marketing at AMD, and found out that all so far available types of GCN cards also support feature level 12_0 of DX12. Though he didn’t want to confirm if all GPUs of this architecture are able to run it.
Tonga and even the newer Carrizo-APU will do for sure, same goes for the GPU of the Xbox One and due to this probably also the Hawaii-GPUs. On the other hand this is unclear for Bonaire and especially the older chips Tahiti, Pitcairn and Cape Verde. ComputerBase is trying to get for information regarding this.
 
The feature level 12_1 seems to be restricted to Nvidias GM200, GM204 and GM206 GPUs so far.
AMD didn’t want to comment on Fiji.
 
According to Hallock the absence of feature level 12_1 shouldn’t be a problem. From his point of view all relevant features for games are contained in feature level 11_1 and 12_0. On top of that most games would be oriented on consoles and will barely utilize 12_1.
 
However these comments are to be taken with caution. As long as a manufacturer doesn’t have or use a feature it always is irrelevant from his perspective. Same happened with Nvidia for example when Kepler didn’t support feature level 11_1.

the source updated their article with a list with clarifications: GCN 1.0 is limited to DX 11_1 feature level


GCN 1.0 based GPUs:

• Oland
• Cape Verde
• Pitcairn
• Tahiti

as per source, updated again, the complete GPU list with (and without) DX12 support:

this is really big if true - extinction level event  :unsure:

Well Tahiti Pitcairn and Cape Verde are all the original GCN that launched 3 years ago, Bonaire was the next chip, while this is disappointing I don't see the need to be talking about extinctions, i guess the obvious complaint is the fact that all these GPUs are still sold today, but i don't think DX12 is going to be nearly as commonplace as some here think

elaborate, pls.

would be quite big because, if true, AMD lied through their teeth

Some are saying GCN is 12 but not 12.1 compatible according to this document in the OP

[PopReference]

It may have more to do with the new features that DX12 will have then just not being able to run it period, but I can't read the article just guessing based on what I've heard already.

[Sharkyx1]

 

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 . That all GPUs of architecture can deal with it , the manufacturers would not confirm , however .

This is what the article says

[Briggsy]

this is talking about dx12_1. It will be used as much as dx11_1 is, which is to say not very much.

 

We already knew weeks ago the dx12_1 is not supported on current AMD cards, so this isn't really news, just clickbait.

[zMeul]

DX12 is segmented in feature levels

from my understanding: Hallock said 12_1 is not that important for their cards

but 12_0 is another thing, that's the DX12 foundation

[Victorious Secret]

Not all cards will have newest feature support since not all cards will be latest GCN. Similar to the 400-700 series for Nvidia. You will get DX12 but not all parts and certainly not much better going forward into 12.X releases.

It's worse for AMD since the 3XX is largely rebrands of 2XX.

[alamox]

well these are cards out in like 2012, ofc they are not DX12 ready, they are basicaly talking about 270, 280, 250; surprised to see the 260 there though

[Humbug]

 

This has been floating around for a while, is it fake or real?

and most of the 2xx series was a rebrand of the HD7xxx series .. your point?  <_<

[Kurosaki Isshin]

think they will rebrand and leave DX12 out of some?

that would suck. I expect it maybe from the low-end stuff. but mid-high I want DX12 D:

Don't worry, they will all support DX12 and Vulkan. Same for all Nvidia Kepler and Maxwell cards.

There may be a few small feature level differences.

[Briggsy]

It's real, but for dx12_0 only.

 

12_1, which the OP article talks about, is probably about as relevant as dx11.1 was. The reason is because of the Xbone. What it supports (12_0) will effect pc gaming greatly.

They are basically saying that all current GCN cards will support 12.0 but not 12.1, including Hawaii. They are not sure about Fijii yet so so far only Nvidias newset series is known for 12.1 support.

 

Will do a full translation real quick..

ok, what about the passage with:

Fraglich ist es dagegen bei Bonaire, vor allem aber bei den ältesten Chips, Tahiti, Pitcairn und Cape Verde.

ComputerBase versucht diesbezüglich noch weitere Informationen zu erhalten.

[Toddwjp]

sounds like amds constant re-badging might bight them in ass a little with lower end cards, dont think it will be a big issue though

[TheTiger]

They just say, that they don't know yet and will try to get more information about it

Tonga and even the newer Carrizo-APU will do for sure, same goes for the GPU of the Xbox One and due to this probably also the Hawaii-GPUs.

The feature level 12_1 seems to be restricted to Nvidias GM200, GM204 and GM206 GPUs so far.

[WaitForMeImOnDialUp]

all gcn gpus are dx12 capable..will have 100% dx12 usage..not dx12.1 however.

 

but the .1 has never mattered,dx 11 was just as good as 11.1,hell i saw absolutely no benefit from 11 to 11.2.

yes, that part - that's really big

thank you for translating that, that is pretty informative. I was under the impression that GCN 1.1 was only different to 1.0 in regards to Powertune 2.0, true audio, dx11.2 and VSR. Everything else seemed to scale pretty flat from tahiti to Hawaii, so why Hallock is keeping a lid on it could be a marketing thing to get people to upgrade, or it could very well be that GCN 1.0 is missing some feature support.
