AMD confirmed after the CES 2016 that its Polaris architecture based Graphics cards will be in a variety of both mid-range and high-end products. For high-end GPUs they will use the HBM2 and GDDR5 for mid-range products, which allow you to purchase a very powerful graphics (compared to the current generation of AMD and NVIDIA) a succulent saving money along the way about the high-end next generation memory.
Polaris based GPUs Will Feature both GDDR5 and HBM2 memory

“AMD helped lead the development of HBM, was the first to bring HBM to market in GPUs, and plans to implement HBM/HBM2 in future graphics solutions.
At this time we have only publicly demonstrated a GDDR5 configuration of the Polaris architecture.It’s important to understand that HBM isn’t (currently) suitable for all GPU segments due to the current HBM cost structure. In the mainstream GPU segment, GDDR5 remains an extremely cost-effective, efficient and viable memory technology.”
Robert Hallock, Technical Marketing lead at AMD
“We have the flexibility to use HBM or GDDR5 as costs require. Certain market segments are cost sensitive, GDDR5 can be used there. Higher-end market segments where more cost can be afforded, HBM is viable as well.”
This permits AMD to exploit GDDR5 to address cost delicate portions of the business sector with items that can make due without HBM. Conversely, with flagship products where there’s a requirement for high memory transfer speed, generally unattainable by GDDR5, and where expenses can be managed, the upsides of HBM can as effortlessly be utilized.
