What does this table documentsEdit

When I started this page, I intended to document the hardware. But of course, the hardware requires device drivers to be used conveniently. But each operating system needs specific device drivers. What if the hardware could support drivers that comply with say Vulkan 1.0, but nobody bother to write drivers for that? This seems to be the case for the TeraScale 2 (VLIW5) and TeraScale 3 (VLIW4). These GPUs could run Vulkan, but there are no drivers for them. I think in such a case we document, no support.

Direct3D 12.0 feature_level 12.0 is not supported by many AMD or Nvidia GPUs! But instead only Direct3D 12.0 feature_level 11.bla. This is a fact, and should be documented correctly.

A good technical sourceEdit

I'd consider

good and reliable sources for information. There might be huge discrepancies between the facts and the intentions of the AMD/Ndvidia/Intel/etc. marketing departments of course. User:ScotXWt@lk 11:27, 21 February 2017 (UTC)

AMD hardware templatesEdit

Please keep both the templates Template:AMD APU features and Template:AMD GPU features up-to-date. User:ScotXWt@lk 11:47, 15 June 2015 (UTC)

Can we remove the title within both templates? I find it unattractive if there is already a title (header) in the article and then there is a second one from the template. Wikiinger (talk) 19:24, 24 August 2017 (UTC)
Seems reasonable to me. Dbsseven (talk) 20:26, 24 August 2017 (UTC)

Engineering vs MarketingEdit

I will rebuild the table based on the engineering names rather then the marketing names. E.g. the marketing name "AMD Radeon Rx 200 series" encompasses 40nm Terascale 2, 28nm GCN 1.0, GCN 1.1 and GCN 1.2 products. The problem is that all these have very different featutres, e.g. the 40nm Terascale 2 will not receive DirectX 12 support. User:ScotXWt@lk 13:44, 10 August 2015 (UTC)

Polaris/Arctic IslandsEdit

The GPU is composed out of a couple of fairly independent blocks. The GFX = 3D engine = GCA = Graphics and Compute Array of GCN 3rd gen and GCN 4th gen (Polaris) is identical. Since most people actually care about the 3D engine, maybe we should stop calling Polaris GCN4… But the other blocks are different though. Especially the DCE display controller engine received some nice updates. And the GPUs are manufactures in a new process 14nm. User:ScotXWt@lk 11:14, 21 February 2017 (UTC)

Vulkan for GCN 1 and 2 in Windows Full availableEdit

Only in Linux WIP (work in progress) — Preceding unsigned comment added by (talk) 18:21, 25 October 2016 (UTC)

Not sure about Win 7/Linux, but my driver report Vulkan 1.1.70 for R9 290 on Win10, so I assume all GCN cards have support for it now (talk) 19:38, 7 May 2018 (UTC)

Video Core NextEdit

The APU version of Vega is reported to include a replacement for the VCE and UVD, termed the Video Core Next. As this means there are two version of Vega (with UVD/VCE or with VCN), can anyone think of a graceful way to indicate this? ScotXW or Wikiinger, any thoughts? Dbsseven (talk) 22:58, 27 November 2017 (UTC)

Is this already for sure? Anyways, I guess it has to done like in the case of Volcanic Islands, supplemented by a footnote. My 2cts Wikiinger (talk) 21:08, 29 November 2017 (UTC)
Phoronix is a pretty reliable source, in my experience/opinion.[1] This seems like the best we'll get unless this is noted in a programming guide for Raven Ridge, whenever that comes out. Dbsseven (talk) 17:34, 1 December 2017 (UTC)

Template with ParametersEdit

I started working on a template with parameters and conditional logic, to display only certain parts of the table. See here User:Wikiinger/sandbox/AMD GPU features, however it is not quite there yet... Wikiinger (talk) 19:59, 8 May 2018 (UTC)

Forum postsEdit

@Matthew Anthony Smith: We seem to be going back and forth about your recent edit of the Direct3D support level of TeraScale 2 and 3. My issue is not what the source says, but if the source is reliable. Reliable sources are required for citation, and citation is required for inclusion of new information. A forum post is explicitly NOT citable, per wikipedia policy on self published sources. Dbsseven (talk) 17:29, 25 May 2018 (UTC)

To be clear, my point is not if DxDiag is reliable, but if the forum poster is reliable. Dbsseven (talk) 17:34, 25 May 2018 (UTC)
fair enough, but there is no sources of this because no one has looked at DXDiag with their Terascale 2+ series cards and posted about it.. until now, i know the picture wasn't doctored, and because of wikipedia's rules you will never get the up to date information on Direct3D since it changes all the time with windows updates.— Preceding unsigned comment added by Matthew Anthony Smith (talkcontribs)
I understand your frustration with feature sets of older hardware. But unless there is a reliable source, a forum post cannot be used as the source for an edit. A core policy of WP is Verifiability and in this case there is not a reliable source to support the edit. (Verifiability, not truth.) It should be reverted. Dbsseven (talk) 17:46, 25 May 2018 (UTC)
Since the fundamental issue (forum posts cannot be the basis for edits per WP:SPS) is unchallenged, I am going to go ahead and edit accordingly. This can be discussed further here if needed. Dbsseven (talk) 03:51, 2 June 2018 (UTC)
