Sorry for all of these single item news posts I keep making, but this is how the information is coming out about AMD's upcoming Fiji GPU using new HBM (high bandwidth memory) technology. (And make no mistake this is exactly the way that AMD marketing dreamed it would happen.) Below we have an image of Fiji: the GPU die, the interposer and the four stacks of HBM.
That chip is massive, quite simply, measuring about 70mm x 70mm based on the information presented during our HBM technical session last month. That is gigantic when compared to other GPU dies alone but is smaller than previous generation GPUs and the required memories on the PCB separately.
In case you missed it earlier today, AMD also released a teaser video of a CG Radeon card using Fiji. We'll know everything (maybe?) about AMD's latest flagship on June 16th.
