What fascinated me about Fiji and the Fury cards was HBM. I am sure it was mentioned here, but I had a Déjà vu moment last night. Sony's PS2's use of HBM . I remembering it being a radical idea and for the majority of the PS2's life, it was a complete pain in the arse to work with. I give props to AMD for giving it a go, as I think this is the future, not only with GPU's, but CPU's. A 14nm 12 core CPU with 32GB of HBM and hyperthreading would give me morning wood.
