    3D stacking manufacturing process, GPU and memory chips are closely stacked and thus better (shorter) connectivity between them => high bandwidth with lower power.

    with first generation of HBM you'll get 2GB at 256GB/s or 4GB at 512GB/s / core. Later versions can scale up to 8GB/core at 2TB/s (2016).

    Edit: Actually it is up to 64GB at 2TB/s with 2nd generation HBM.

    Thanks a lot!

    Also, can they do 8GB at 512 bit with the 1st gen HBM or only 4GB is allowed?

    From these leaked slides it doesn't look like, they show a limit of 4 stacks/128GB/s (4x128=512) with 1GB/stack maximum for the first generation.

    In fact the HBM bus width is 1024bit even for the first generation, so make that 1TB/s

    Bring it on. Anything that makes the competition more fierce is a good thing.

    Mantle V1 is good enough, API doesnt need adjustments like TressFx or Physx :p


    OT; good, hopefully it will be cooler too..

    Luckily, in this case they just need to get the card to run to see the benefits, no special drivers required :)

    I'd be happy if they'd release a Mantle driver that would detect my second screen :bang:

    They should release drivers that are worth a damn instead of releasing a new card...

    Nice!

    Since the ram is stacked how hot will they get and how would they be cooled?
