by Slobodan-Simic (Nov, 2013)While CUDA 4 already had unified virtual addressing support which allowed x86 and GPU memory to be addressed together in a single space, it only simplified memory management and did not solve some issues that such a solution had and still required memory copying that will allow GPU to work with it.
by Syed-Muhammad-Usman-Pirzada (May, 2014)The stated official performance figures are on par with the original Mantle figures, with Star Swarm showing a major performance increase and Battlefield 4 showing a small but significant performance increase.
Features Key features of the Radeon Instinct MI6
memory bandwidth Rate at which data can be read from or stored in onboard memory
pixel rate Number of pixels a graphics card can render to the screen every second
texture rate Speed at which a graphics card can perform texture mapping
floating point performance How fast the gpu can crunch numbers
shading units Subcomponents of the gpu, these run in parallel to enable fast pixel shading
texture mapping units Built into each gpu, these resize and rotate bitmaps for texturing scenes

The stated official performance figures are on par with the original Mantle figures, with Star Swarm showing a major performance increase and Battlefield 4 showing a small but significant performance increase.
Now this particular update, along with the various performance updates and bug fixes will include 2 major updates.

Nvidia also revealed that while we are currently seeing software implementation of unified memory with CUDA 6, Maxwell will most likely have some sort of hardware functionality for implementing unified memory thus removing any performance penalties and most likely doing it much better than software solution with CUDA 6.
While it does not resolve technical limitations that require memory copying, like limited bandwidth and latency of the PCIe, it moves memory management to CUDA rather than other toolkit, thus simply making the life of the programmer much easier.

Kicking off next week will be the annual International Conference for High Performance Computing, Networking, Storage, and Analysis, better known as SC.
Maxwell will have some kind of hardware functionality for implementing unified memory (and presumably better performance for it), though it’s not something NVIDIA is talking about until Maxwell is ready for its full unveiling.
