AMD Confirms GCN Cards Don't Feature Full DirectX 12 Support - Feature Level 11_1 on GCN 1.0, Feature Level 12_0 on GCN 1.1/1.2

AMD Confirms GCN Cards Don't Feature Full DirectX 12 Support – Characteristic Level 11_1 on GCN i.0, Feature Level 12_0 on GCN 1.1/ane.two

There has a lot of talk going on around DirectX 12 and how new and current graphics cards would utilize the latest API to leverage performance in upcoming gaming titles. In an interview with Computerbase regarding DirectX 12, AMD's Robert Hallock (Caput of global technical marketing) revealed that their current GCN cards don't characteristic full DirectX 12 support and are express to Feature Level 12_0 while the rivaling Maxwell graphics cards have total Characteristic Level 12_1 support.

AMD DirectX 12 Support Limited To Feature Level 12_0 - Fiji Might Exist The Only Feature Level 12_1 Compliant Architecture

DirectX 12 volition be the latest API from Microsoft that is built to leverage operation across several platforms. It is designed for PCs, Consoles, Tablets and fifty-fifty phones that are running the Microsoft Windows ten Os. Since its announcement, graphics manufacturers such every bit Intel, AMD, NVIDIA and fifty-fifty Qualcomm have claimed that the hardware they built will fully support DirectX 12 capabilities. We have come up a long manner since the revelation and bits by bits, nosotros go more information regarding the different feature levels and advantages of the API. The first thing nosotros knew well-nigh DirectX 12 API was that it was built for low CPU overhead by reducing the CPU bottleneck faced by the graphics bill of fare and fully utilize the processor to its maximum potential. The other features included more than command over hardware by the developers and a fully asynchronous calculating method which is faster and efficient.

The reference DirectX 12 API (Feature Level 11_0) has performance targeted features while the other 2 level deliver graphical improvement and this is what really matters in improving the games visually. The feature level 12_0 comes with Tiled Resource, Typed UAV Access and Bindless Textures support. Feature Level 12_1 has the Raster Social club Views, Conservative Raster and Volume Tiled Raster enabled on the API. We have talked near these features in previous manufactures detailing the performance improvement, explicit multi-adapter technology and graphical updates. Just to enable these new technologies, the hardware built past companies need to be full compliant with it.

AMD has recently confirmed that their current cards can support Feature Level 12_0 at all-time while NVIDIA'south Maxwell ii.0 architecture has support for Feature Level 12_1. The cards that feature level 12_ 0 back up include Radeon HD 7790, Radeon R7 260 (X), Radeon R9 285, Radeon R9 290 (Ten) and R9 295X2. The older cards such as the ones based on Tahiti, Pitcairn that include all the 7000 series cards (excluding Hd 7790), Radeon R9 270 (X) and Radeon R9 280 (X) characteristic up to Feature Level 11_1 support. Robert Hallock believes that at that place's no trouble with not feature DirectX Feature Level 12_1 support since features are performance enhancing tools are already bachelor in 11_1 and 12_0 and nearly games won't rely on utilization of 12_1.

According to Hallock, the absence of the feature level 12_1 is no trouble in principle. So the key for games features are all included in the feature level 11_1 and 12_0. In add-on, about games would already geared to the console and thus inappreciably rely on 12_1.

This however could injure AMD in the long run against Maxwell (GeForce 900 series) cards that are compliant with DirectX 12 feature level 12_1 and that was proved in their contempo GeForce GTX 980 Ti launch. NVIDIA'south older cards, such every bit Kepler and Fermi come up with Feature Level 11_0 support with partial Feature Level 11_1 support.

This could mean that AMD'south only Feature Level 12_1 compliant carte would be their new Fiji GPU based cards launching this calendar month. However, judging by Robert Hallock'southward statement on how DirectX Feature Level 12_1 isn't of import for them, information technology could also hateful that that they volition also take express support on Fiji but that is even so to be confirmed.

UPDATE :

@Ramzinho @amd_roy DX has always had FLs, but they're for devs. Not meaningful for users. You support DX12 or yous don't. THAT'S what matters
