Micron Begins to Sample GDDR5X Memory, Unveils Specs of Chips
 

This past week Micron has quietly added its GDDR5X memory chips to its product catalogue and revealed that the DRAM devices are currently sampling to partners. The company also disclosed specifications of the chips they currently ship to allies and which potentially will be mass-produced later this summer. As it appears, the first samples, though running at much higher data rates than GDDR5, will not be reaching the maximum data rates initially laid out in the GDDR5X specification.
