Micron announced that it has begun mass production of next-generation GDDR6 memory chips, and is the last of the DRAM giants. Samsung and SK Hynix have mass-produced and shipped GDDR6.
Not only is the progress slow, but the Micron GDDR6 also lags behind the other two in terms of specifications. At present, the single capacity is 8Gb (1GB), and 16Gb (2GB) will be available later.- The maximum allowable GDDR6 is a single 32Gb (4GB).
In terms of speed, Micron's first offering 10Gbps, 12Gbps, 14Gbps Three options, voltages of 1.25V and 1.35V, are significantly lower than GDDR5 1.5-1.6V, which naturally helps save power.
16Gbps particles are also under development. Micron has even demonstrated 20Gbps ultra high speed internally. Of course, Samsung started mass production of 18 Gbps earlier this year.
However, even with low speeds of 12Gbps, GDDR6 has a high bandwidth of 48GB/s, which is half that of the fastest GDDR5. 14Gbps GDDR6 is up to 17% faster than the fastest GDDR5X.
If it is 20Gbps, that bandwidth is a terrible 80GB/s. The total bandwidth under a 256-bit bit-width can reach 640GB/s, twice the GTX 1080, and even approaching the Titan V of HBM2 memory.
Micron said that in addition to traditional GPU graphics, their GDDR6 memory can also be used in AI artificial intelligence, networking, automotive and other fields.
