Intel's Skylake-S will feature a new integrated graphics core with support for DirectX 12, OpenGL 5.x and Open CL 2.x. Skylake-S will be a bit of a strong duck, this 14nm architecture is actually the successor of Broadwell, the upcoming 14nm shrink of the current Haswell architecture, but both architectures are expected to coexist and sit on top of each other in 2015.
We cannot guarantee that the DirectX 12 support means that it will support all fixed function hardware features of the DirectX 12 API. It could indicate lower level support, closer to the AMD’s Mantle API.
The new thing that comes from the house of Intel is accelerated media support for the latest generation codecs including HEVC, VP8 and VP9. Intel doesn’t specify what sort of High Efficiency Video Coding it supports as this video compression standards goes all the way to 8192x4320.
Skylake-S graphics supports display resolution up to 4096x2304 which should be enough for everyone. Essentially this is 4K in 16:10. It comes with support for three independent displays. Intel HD graphics features embedded Display Port eDP.
