The gddr6 memories could go up to 20 ghz

Micron in its latest research article has revealed the full potential of its next GDDR6 memory, which will be equipped with the latest graphics cards from GPU manufacturers, especially NVIDIA. GDDR6 memory has been in Micron's labs for quite some time and it looks like it is almost ready to take its place within mass manufacturers' graphics cards.

GDDR6 memories could reach 20 GHz 960 GB / s

Micron looks at various aspects of GDDR6 memory, including silicon changes, channel enhancements, and performance measurements. Although GDDR6 follows an evolutionary path with respect to GDDR5 and GDDR5X memories, there are still some significant changes to the underlying architecture to increase memory bandwidth while saving energy.

One striking detail is that Micron has already determined in performance measurement that its GDDR6 memory could extend beyond the 16.5 GHz range. The result showed that with a slight, but useful increase in I / O voltage, memory chips can reach speeds of up to 20 GHz, which is a significant jump from the JEDEC- defined 14 GHz target.

If we calculate, a 256-bit card with these speeds would be able to offer a bandwidth of 640 Gb / s that is close to Titan V's 652.8 Gb / s, which uses HBM2 memory. A 384-bit card would almost reach the 1 Tb / s barrier with an approximate bandwidth of 960 GB / s, beating NVIDIA's Tesla V100 solution.

Micron mentions that they are very sure that the speeds that GDDR6 will offer are going to extend beyond the speeds defined by Jedec (14 GHz), so this is just an indication of the overclocking potential that we would see in the next graphics cards. generation.
