Upcoming GPUs (2016)

.... I was just saying.

I completely agree with your simplification; it was just that proposed 48GB card!!. You're going to start rumours.

/e re: HBM
In HBM1, each stack interface was 1024bits wide with 2Gb chips (256MB), 4 chips per stack (1GB per stack), the GPU memory controller interface was 4096bit, so, 4 stacks are needed.

HBM2 looks to be coming in 1024bits (still), with 8Gb chips in 4 or 8 chip stacks (rumours from Samsung), i.e. 4GB per stack (currently), potentially 8GB in a stack! With a 4096bit GPU interface, and it will pave the way for 16GB or potentially 32GB cards.

The math gets harder with HBM as you need to add in the number of chips per stack.
