NVIDIA has updated their roadmap for future and the next step after Maxwell would be Pascal expected to be launched in 2016. Since NVIDIA officials themselves declared that the performance leap from Kepler to Maxwell won’t be as noticeable as the one from Fermi to kepler. Therefore NVIDIA has some big plans for the next big thing in the GPU lineup. The stats and features declared by NVIDIA consists of a totally new Graphics interface called NVLink which may replace the use of x16 PCI-E slots and the standard vertical orientation of the dedicated graphics accelerator.

Replacing the Maxwell

As said earlier, NVIDIA® themselves said that Maxwell aims towards a better Performance/watt ratio and efficiency rather than out powering the Kepler chips. Most rumored features of Maxwell architecture is the incorporation of an integrated CPU which would decrease the dependency on CPUmain . The main wave of Maxwell GPUs (except GM-107) is expected to be molded on 20nm nodes and feature UVM for the first time in GeForce lineup. So now let’s see what features Pascal would offer

Now, as far as Pascal is concerned, the list of features goes on and on. NVLink, 3D memory, UVM (would be firstly featured on Maxwell), cache coherency and 20nm nodes. And the two main features are explained below

NVLink: A super fast interface for the Pascal based GPUs replacing the good old PCI-E lane running at x16. The NVLink is said to provide better Multi-GPU scaling than multi PCI-E setups and the difference would be as high as 5 times more.

NVLink Multi GPU scaling : 5x more bandwidth

3D Memory: Stacked piles of memory modules which would replace GDDR5 and provides higher bandwidth than GDDR5 modules.

 

Conclusion

The overall form factor would also be decreased compared to present cards of equal potential. NVIDIA® compared the length of the reference card prototype with a pen’s length. And this would decrease the overall form factor of PCs. Stay tuned for more or if you have a question then feel free to ask in the comment section
