GDDR5X has entered mass production



When Nvidia announced their GTX 1080 with GDDR5X memory many people were concerned that initial supply of this new GPU would be constrained by the availability of GDDR5X memory,  as this new memory type was initially intended for mass production in summer 2016.  

Now Micron has announced that their new GDDR5X memory has already entered mass production, alleviating concerns that this new memory type would constrain the supply of next generation GPUs. 

Nvidia's GTX 1080 will be the first GPU to use GDDR5X memory, allowing the GPU to have almost as much memory bandwidth as a GTX 980Ti with only a 256-bit memory bus. The GDDR5X used in Nvidia's GTX 1080 runs at a quad data rate of 10GB/s, which is 3Gb/s  faster than the GDDR5 memory used on the GTX 980Ti, while consuming a similar amount of power per chip.

GDDr5X memory allows that GTX 1080 to achieve much greater performance per watt, allowing it to achieve high memory bandwidths with a smaller memory bus and fewer memory chips.  Below is a statement from Micron regarding their GDDR5X memory. 


       Designed by our specialized team of Graphics memory engineers in Munich, GDDR5X provides NVIDIA with an unprecedented level of memory bandwidth for their new GeForce GTX1080. The bandwidth delivered by Micron’s GDDR5X memory is the result of thousands of hours of teamwork by some of the most brilliant minds in our two companies.

Right now we do not know if AMD will be using GDDR5X memory in any of their upcoming Polaris GPUs, but as you can see from the table above GDDR5X allows GPU makers to achieve high memory bandwidths with smaller memory bus sizes and with lower power draw, which makes it the perfect memory choice for AMD's efficiency driver Polaris GPU designs. 

HBM 2 memory may be able to achieve faster speeds and lower power draw than GDDR5X, but that memory type has not entered mass production yet and is still a long way from being released in a consumer GPU, leaving GDDR5X as the best memory type for modern GPUs.

Still expect some supply issues. You won't get much volume increase after a couple months of entering mass production. Depending on when they started, if it's less than 2 months, 1080 supply will be limited for a while.Quote
