In order to support the ability for NVIDIA’s Kepler architecture to launch additional workloads a new Grid Management Unit was built that handles the incoming workloads from the host system as well as the algorithmically created workloads and balances accordingly.

Intel Will Not Bring eDRAM to Socketed Skylake

by Scott Michaud |

It seems to have been demonstrated that, in some situations, and ones relevant to gamers at that, that this boost in eDRAM can help computation - without even considering the compute potential of a better secondary GPU.
Since the original claim was that Broadwell-C is better than Skylake-K for gaming, giving a 25% boost to GPU performance (or removing a 20% loss, depending on how you look at it) could tilt Skylake back above Broadwell.
NVIDIA calls its software implementation GameWorks VR and AMD calls its software support LiquidVR.
Things will be tough for developers in this short window of time, but Oculus claims its necessary to "allow them to more rapidly evolve the software architecture and API.
We expect to see official details of the R9 300-series of products of which there have been many leaks as well as the final details of the AMD Fury and Fury X products based on the new Fiji GPU.
