Micron Says GDDR6 Rumors in 2016 are False

 

Recently rumors have been coming from certain websites that GDDR6 would be arriving with some new GPUs in 2016, but Micron has came out and said that these rumors are false, stating that they have made no announcements regarding GDDR6 and that they will be bringing GDDR5X to market in 2016. 

From what we know about GDDR5X memory we know that it has a very similar memory architecture to currently available GDDR5, with the main change being that the memory has double the pre-fetch from 8 data words per memory access to 16 data words per data access, in theory giving the memory double the theoretical bandwidth while maintaining an architecture that is nigh identical to GDDR5.

 

    The new memory advancements coming from Micron in 2016 are going to be called GDDR5X, not GDDR6. GDDR5X and GDDR6 are not the same product and Micron has not announced any plans involving GDDR6.

 

Nvidia to use GDDR5X memory with next generation GPUs

 

Right now it is rumored that Nvidia will be using GDDR5X memory with some of their upcoming Pascal GPUs, offering double the speeds of existing GDDR5 memory. 

Micron designed GDDR5X and has approached JEDEC to make GDDR5X a memory standard, so that this memory can be adopted into the industry more widely. So far in the first generation of this memory Micron has increased the memory data rates of GDDR5 from 8Gbps to between 10-12Gbps with GDDR5X, with future iterations hoping to surpass 14Gbps mark or even reach its theoretical maximum of 16Gbps.  

Micron expects GDDR5X to be able to hit the market in the second half of 2016, just in time for a new generation of GPUs. With supply of HBM and HBM 2.0 memory being very constrained it is likely that some next generation GPUs will need to run on GDDR5 memory, though with the availability of GDDR5X GPUs can still use GDDR memory and not have as large of a bandwidth disadvantage when compared to HBM. 

When compared to GDDR5X, HBM and HBM 2.0 still has significant advantages, as it consumes less power, reduces the required PCB space for a GPU and HBM 2 offers a significantly higher amount of bandwidth than GDDR5X.

Any word on the power draw of GDDR5X compared to GDDR5 or HBM?Quote

It will definately be higher than HBM, but I don't know how it will compare to GDDR5Quote

Really the only differences are bandwidth. Just doubling essentially. Everything else should be the sameQuote
