Nvidia's 'Pascal' set to feature HBM 2.0

Leaked slides from Nvidia's GTC Taiwan Presentation show HBM Memory in their Next-Gen GPU Range

 Nvidia's upcoming next-generation 'Pascal' is expected to feature HBM 2.0 (High-Bandwidth-Memory) in it's product line due to be released sometime in the first quarter of 2016. A leaked slide from Nvidia's GTC Taiwan 2015 presentation shows clearly an illustration of it's next generation GPU with HBM memory on the GPU die. According to the leaked slides, Nvidia will name it's HBM stacked memory as '3D Memory'.

The move to HBM by Nvidia makes sense as their main competitor AMD has recently released it's 'Fiji' range with HBM. If Nvidia were to include HBM 2.0 in it's upcoming GPU lineup, it will have a memory bandwidth of around 1 TB/s, which is double the speed of AMD's current generation 'Fiji' based GPUs.

Current rumors also indicate that Nvidia will include up to 16 GB of HBM 2.0 memory, however looking at the illustration on the slide, it's unlikely that this will be true as the picture shows the GPU with 4 stacked memory modules, AMD have the same setup with 1 GB of HBM on each stacked module, this would mean that each module would have to be 4 GB each. As HBM technology is at it's early stages, it's unlikely that 16 GB can be achieved.

What we do know is that Nvidia will most likely manufacture it's 'Pascal' GPU in 16nm FinFET process by TSMC.
