JEDEC Solid State Technology Association, the global leader in the development of standards for the microelectronics industry, today announced the publication of JESD232 Graphics Double Data Rate (GDDR5X) SGRAM. Available for free download from the JEDEC website, the new memory standard is designed to satisfy the increasing need for more memory bandwidth in graphics, gaming, compute, and networking applications.

Derived from the widely adopted GDDR5 SGRAM JEDEC standard, GDDR5X specifies key elements related to the design and operability of memory chips for applications requiring very high memory bandwidth. With the intent to address the needs of high-performance applications demanding ever higher data rates, GDDR5X is targeting data rates of 10 to 14 Gb/s, a 2X increase over GDDR5. In order to allow a smooth transition from GDDR5, GDDR5X utilizes the same, proven pseudo open drain (POD) signaling as GDDR5.

"GDDR5X represents a significant leap forward for high end GPU design," said Mian Quddus, JEDEC Board of Directors Chairman. "Its performance improvements over the prior standard will help enable the next generation of graphics and other high-performance applications."

I wonder if it will be more price friendly than HBM. If yes, this could prove useful to bump up mid graphics segment without major price increase. Meaning 4K may become more accessible to wider audience.

Most probably yes. It should not be very far from the price of gddr5 and slapping them to graphics cards are not any different between them either. So no extra manufacturing process is needed... But then again has anyone has any clue how much hbm:s actually costs?

Hmmm..
I'd like to see a Fury made with this as well as a 980ti.

I believe this is the point and to leave HBM to the high end segment.

Difference between CUDA and GCN architecture in cache prefetch size, could mean that nvidia will have to use pseudo-independent memory accesses to avoid overfetch penalty in exchange for some bandwidth ... interesting article: http://monitorinsider.com/GDDR5X.html

So AMD could seriously cheapen a Fury for refresh with minor PCB changes...going from BGA 170 to 190..
Interesting...IMO this should equate to a $300 Fury soon.
