GDDR6 promises 20 percent lower energy consumption than GDDR5X but will not be as fast as the more expensive HBM2. Over time you can expect bandwidth of up to 16Gbps, which is double as much as GDDR5 and also quite a bit more than GDDR5X, which spec covers a range from 10Gbps to 14Gbps. GDDR6 will be used for gaming video cards and consoles, but also for high performance computing applications.
The memory company is speeding up the release of GDDR6 to cope with faster PC and console upgrades. GDDR6 will be significantly faster than its predecessor, GDDR5X, which is still reaching GPUs. Micron had originally planned to release GDDR6 next year.
Virtual reality is also driving PC upgrades, but not at the same pace as gaming and e-sports, which are forcing faster development of new graphics memory technologies, said Tom Eby, vice president of the computing and networking business unit at Micron.
