FUD Zilla learned that AMD's upcoming Sea Islands GPUs will support the yet to be announced DirectX 11.1 API:
Richland A series Trinity successor in 28nm will end up with current generation Northern Islands Radeon HD 7000 cores, while the Kabini gets Sea Island Radeon HD 8000 cores. Many expect to see Sea Islands in discrete and mobile graphics form this year, but this is not something we can confirm at this time.
Despite the fact that some APUs might end up with the same number or graphics cores (shaders) AMD is quick to point out that next generation cores will be different and that e.g. 384 Sea Islands cores won’t be the same as 384 cores of Northern Islands. In a perfect world the new generation should end up significantly faster.
