Red Hat spolu s Nvidií vyvíjí nové obecné API, které bude řešit adresní prostor CPU na GPU. API umožní, po jeho použití v ovladačích GPU, používat uploading textur bez potřeby operací memory copy, stejně jako načítání textur přímo z disku a bude to celé použitelné s OpenGL a výpočetními shadery.

I think at this stage it makes sense for us to develop Mantle, at least in its current form, because nobody knows our hardware at the lowest level best than we do. So for us to have to do that for alternative graphics hardware [would be] almost impossible.

"If a competitor were to approach AMD to make their own backend and drivers for Mantle, AMD would not dismiss them right away."

žádná Nvidia Mantle verze nebude

They're describing Mantle as a to-the-metal API. The API is the language your drivers use to talk to your video card and execute the game rendering. Windows uses the DIrectX API with is hardware agnostic and comes with significant overhead by virtue of being agnostic. A to-the-metal API speaks directly to the hardware circumventing the software API, such as DirectX, resulting in significant performance improvements. This is what you see done in consoles and how such ancient hardware can even run games like BF3 today.

The caveat to a to-the-metal coding is that it is hardware specific and works only with the hardware it is designed for. In this case Mantle will only run on AMD cards using the GCN architecture; 7XXX series and the upcoming R9 2XX series. If you turn on the Mantle API rather than DirectX 11 API in Battlefield 4 and it does provide a to-the-metal performance benefit, it is going to give the AMD cards a big advantage compared to nvidia cards using DirectX11.
