AMD Reveals Its Graphic Cards Don’t Feature Full DirectX 12
AMD has stayed quiet for the most part about its general support for DirectX 12, and how its current generation graphic cards would handle it.
For the first time, in an interview with Computerbase, Head of Global Technical Marketing Robert Hallock that their current generation GPUs do not feature full DirectX 12 support. According to Robert Hallock, the current line of GCN graphic units available from AMD are limited to Feature Level 12_0, which is a stage below rival Nvidia’s Level 12_1 support with its Maxwell series of cards.
DirectX 12 is the next API set to be the leverage for games across multiple platforms, ranging from PC to consoles, and even supporting the mobile market which run Windows Phone operating systems. DX12 is expected to arrive with Windows 10, and major firms such as Qualcomm, AMD, and Nvidia had claimed that the hardware they build will support the new API.
The breakthrough feature of DX12 is its capability of overcoming the well-known issue of CPU bottlenecking. In addition to this, it was also going to bring fully asynchronous computing methods for faster and more efficient processing.
AMD’s GCN cards that support Feature Level 12_0 are Radeon HD 7790 (non Tahiti), Radeon R7 260 (X), Radeon R9 285, Radeon R9 290 (X) and R9 295X2. All other HD 7000 series cards, R7 250X, R7 265, R9 270 (X), R9 280 (X) support Feature Level 11_1 for DirectX 12.
According to Hallock, there is no real loss or problem in principle in the absence of support for Feature Level 12_1, as all the game-related features are already available in Feature Level 11_1 and 12_0.
This could however hurt AMD on the long run, as Nvidia already has Maxwell 2.0 units that fully support 12_1.
