Focused on low power
Greenland is the successor of Fiji, and we don’t think it will be radically new core. The main goal for Greenland is to bring more performance per watt to AMD GPUs in 2016.
Significantly smaller than GDDR5
We had a chance to see the Hynix HMB memory of the future, and even see a next generation HBM2 wafer with many of these next-generation dies.
Interposer it is
Just as it was easy to figure out from Pascal renders, Nvidia’s new GPU architecture is using the 2.5D memory approach, the same one that is expected from AMD’s upcoming Fiji card.

Pascal is Nvidia’s next generation architecture and it is coming after Maxwell of course. The company says it will launch next year, but details are still sketchy.
Cannot fit more on 2.5D interposer
In early January we heard a thing or two about an AMD card codenamed Fiji, the one that comes with High Bandwidth Memory (HBM).
