Samsung delays GDDR6 to 2018
The GTX 1080 and Titan X are the first graphics cards to use GDDR5X memory. NVidia have demonstrated with their latest cards that enthusiast cards be built around GDDR5X instead of HBM or HBM2. Unlike Micron and its investments in GDDR5X, Samsung has chosen to bypass the standard in favour of GDDR6.
Compared to GDDR5X operating at 12Gbps, GDDR6 is expected to offer an internal bandwidth of 16Gpbs. This equates to a memory bandwidth of up to 512 GBps for cards with a 256 bit memory bus, and up to 786 GBps for cards with a 384 bit memory bus. Mobile gamers will benefit greatly from this technology as it has been shown to consume 20% less power than prior implemented standards.
Unfortunately, Samsung announced recently that the highly anticipated technology will not be shipping in graphic cards until 2018, a year later than originally planned.
