Micron has released a GDDR6 memory research paper offering insight on what kind of overclocking potential may be possible with next-generation graphics cards. Initial testing showed the memory hitting 16.5Gb/s, but after bypassing the memory array and adding a small boost in I/O supply voltage, Micron managed 20Gb/s.

So, just what kind of performance could we expect from a 20 Gb/s clock bump? Well, to put things into perspective, a 256-bit card with such speeds would be able to deliver 640 Gb/s bandwidth, which is close to Titan V’s 652.8 Gb/s (HBM2). A 384-bit card would almost hit the 1 Tb/s barrier, with an approximate bandwidth of 960 GB/s surpassing NVIDIA’s Tesla V100 solution.
 
Hmm. Wonder how that would affect hash rate?

Because miners.

;)
 
Less.
It was low watts on a gfx card with GDDR5x.

Do you have a use case that makes it critical?
All the high end cards where the memory would be pulling 100W otherwise and really cut into that 300W window. IO is what burns a lot of power on memory and upping the voltage certainly won't help there and won't be all that useful for smaller form factors and mobile where the market appears to be moving.
