Amd polaris would have no hbm2 memory

Along with the new AMD Radeon Duo Pro graphics card, AMD has shown its GPU roadmap until 2018. During this period, the firm will launch three different GPU architectures, the next being the fourth generation of GCN, better known as AMD Polaris. and that it will arrive in the middle of the year although contrary to what was expected, AMD Polaris would not have HBM2 memory.

AMD Polaris without HBM2 memory?

AMD Polaris will arrive manufactured in 14nm FinFET and will represent a dramatic increase in energy efficiency compared to the current GCN 1.2 used in Fiji and manufactured in 28nm, specifically, there is talk of 2.5 times more performance per watt consumed.

Following Polaris we will have the Vega architecture which in turn will improve Polaris energy efficiency by 50% and will include the stacked memory HBM2. From the latter we can deduce that Polaris will settle for GDDR5X memory just like Nvidia's GeForce GTX 1080.

Polaris was supposed to include the HBM2 memory but it seems that it will not finally be so and we will have to wait in mid-2017 to see it with Vega. Another explanation may be that HMB2 is reserved only for the most powerful next generation cards from AMD and Nvidia, these could be the new Titan and Fury based on Pascal and Polaris.

Beyond Vega Navi will come with a new memory successor technology to HBM2. Too soon to think about it? and that it would improve Polaris' energy efficiency by 2.5 times, it will probably come under a new manufacturing process at 10 or 7 nm.
