10nm parts will need HBM for the mid range. 2018 seems plausible if a little hopeful given the slips we have seen in recent processes ramping up.
Cheap cards will use DDR4 for low cost, or be replaced with integrated graphics and simply not exist.
I do wonder if AMD are being a bit tight-lipped on their future plans for HBM because they're waiting to see what supply will be like. With a single cube of HBM2 giving up to 4GB of VRAM with 256GB/s of bandwidth (slightly better than an R9 280X), high yields of HBM2 could make it viable for mid-range cards in the next generation, but the supply would need to be plentiful and relatively cheap to ensure the kind of volumes that AMD would want for a next-gen card with similar performance to a 380/280X.
Another foible is that use of HBM/HBM2 requires an interposer. The interposer needs to be at a minimum the area of the GPU die PLUS the width of one HBM stack added to one side of the die.
Even on an older process (with amortised setup costs) that means fabbing a pretty big die, and a big fixed cost to add to the manufacturing costs. That means HBM isn't going to be a good fit or low-margin lines.
Isn't the 256GB/s of bandwidth per stack though, I thought the Fury X has 512 GB/s of bandwidth using standard HBM so wouldn't a card with HBM2 have 4x as much bandwidth?Quote:
