AMD Next Gen Vega Graphic Cards, GDDR6 Memory or HBM2?

Leaked or rumored, recently LinkedIn page of an AMD technical engineer that mentioned AMD is working on a GDDR6 memory controller. But many believe that even if it is more than a rumor and its a leak. it is not a leak of a significant and determined strategy by AMD and AMD will probably still be sticking to HBM2 for its high end next generation 12nm or 7nm vega graphics cards in 2018 (aka Navi). On the other hand is the new GDDR6 memory technology that Samsung has developed and the most possible potential customer for that is Nvidia for the next generation of Volta or Ampere Geforce gaming graphic cards. So AMD may be under pressure to jump to the next fast memory platform but as we mentioned in our last report on Samsung Gddr6 tech, it has some implementation issues that may delay it from joining to the final product. AMD has experienced the Navi will next-gen HBM memory, so it remains to be seen whether they are talking about HBM2 or the elusive HBM3 standard (which should be still faster than the GDDR6 standard). Samsung GDDR6 just got the CES 2018 awards. Samsung has currently listed a 16Gb GDDR6 DRAM in their portfolio with a transfer rate of 16Gbps, the DRAM will be able to handle 64 GB/s bandwidth (per chip). The memory operates at just 1.35V. Although Samsung has targeted 2018 for GDDR6, new graphics memory usually takes a long time to reach the market, so the estimate may be aggressive. GPUs will need to be designed for the new memory, and components will need to be validated and tested, all of which takes time. Advances in manufacturing have also created the need for new GPU memory. Some of the latest GPUs based on Nvidia’s Pascal and AMD’s Polaris architectures are manufactured with new techniques including FinFET, a 3D structure in which chips are stacked. New memory like HBM and GDDR6 are designed for such new chip structures.
Samsung 16Gb GDDR6 Memory – The fastest and lowest-power DRAM for next generation, graphics-intensive applications. It processes images and video at 16Gbps with 64GB/s data I/O bandwidth, which is equivalent to transferring approximately 12 full-HD DVDs (5GB equivalent) per second. The new DRAM can operate at 1.35 volts, offering further advantages over today’s graphics memory that uses 1.5V at only 8Gbps. via Samsung

Whatever.
Even current ram is ruinous, and there is NO sign of supply keeping up with demand.
Amd have an ecosystem which may let them punch far above their weight with affordable 4GB vegaS.
The single 4GB stack of HBM2, is supplemented/extended by a pool of cache resources including spare system memory and NVME ssdS, all cleverly managed by HBCC.
AMDs claims of an ~indiscernible, simulated boost of 2-3x installed gpu ram are premature no doubt, but plausible in time.
Afaik, gaming needing 6GB+ is extreme and unusual i.e., most can live with 4-6GB now. With a little help as above, 4GB vega could be quite powerful.
AMD are incentivised.
GPU ram shortages limit gpu sales, so half the ram per gpu means double the gpuS sold.
Amd sell gpuS, not ram.
