Kaap with more of his ridiculous rhetoric on the demerits of HBM. As many have said before, fiji performance was nothing to do with HBM, get over it.
The only reason GDDR5X is being use in place on GP104 1080's is due to it being cheaper to implement, as you do not need to worry about interposers etc. Nothing to do with HBM's performance.
Indeed NVidia decided that GDDR5X was the best option for a high performance card.
How much faster is the 1080 than any single GPU Fiji/HBM based card again, answer quite a lot.
