More info about the new Pascal architecture is slowly leaking from NVidia
The first couple of GP100 Pascal GPU have been succesfully fabricated (tape-out) for testing and evaluation purposes.
Up to 32Gig of HBM, up to 80% faster than a GM200 TitanX or Quadro M6000, just a few numbers. The card will mainly be for professional applications first.
It will be launched together with a new bus. The PCIe3 x16 will be replaced by NVidias own NV link. That will allow to pass 5-12x the amount of data. Especially usefull for multi card setups.
The consumer version will probably be a bit more simple. Maybe less ram and a conventional PCI Express most likely. The current video cards can not even use the complete bandwidth of that bus. Probably half.
Chip will most likely be fabricated at TSMC 16nm technology.
Almost insane to think that the just introduced Maxwell generation will become almost obsolete so soon®
Or it must be rebranded, like ATI/AMD is doing now. Bad habits seem to rub off.
The rebranding will in this case mean a smaller production procedure and higher clocks because of that.
The Pascal consumer cards will without any doubt be the fastest new graphics cards in the world.
