The well-known manufacturer of solutions of memory Micron has confirmed that it will be possible to commercialize GDDR6 memory to 20 GHz doing a simple adjustment in the voltage of the same one, which means that this one will have a greater consumption but also a greater yield.

To give us an idea of ​​the difference that marks just remember that the JEDEC standard sets a speed of 14 GHz for this type of memory, which means that we have an increase of nothing more and nothing less than 6 GHz.

Currently a GeForce GTX 1080 TI graphics card has a bandwidth of 484 GB / s thanks to its 352-bit bus and its GDDR5X memory at 11 GHz. Well, a hypothetical GeForce GTX 2080 TI-1180 TI with a slightly increased bus up to 384 bits and GDDR6 memory at 20 GHz would reach a total bandwidth of 960 GB / s.

GDDR6 memory at 20 GHz applied on a 256-bit bus (like the GTX 1080 and GTX 1070) would leave us with a bandwidth of 640 GB / s , a figure that is very close to the 652 GB / s that reaches GTX TITAN V thanks to its 3,072-bit bus and its HBM2 memory.

With these examples we wanted to illustrate the point of inflection that will mark the arrival of GDDR6 memory in the graphic sector, although we must remember that at first its use will be limited to high-end graphics cards and that mid-range will continue to use GDDR5 memory or GDDR5X.

On the other hand it is also important to bear in mind that GDDR6 memory could be the choice of Sony and Microsoft for their next generation consoles. Except surprise we hope that they maintain the unified memory approach that we saw in PS4 and Xbox One, which means that PS5 and Xbox Two will have a certain amount of GDDR6 memory (probably 16 GB) to be distributed between system (RAM) and graphic memory (VRAM).
