GDDR5X Memory Now In Mass Production
GDDR5X, the fastest discrete memory component in the world, has already entered mass production.
High-Bandwidth Memory offers 1024Gbps of potential bandwidth per stack, and HBM2 purportedly offers double that data rate. The 10Gbps data rate of Micron's current GDDR5X packages is impressive, though, and the new design is much easier to implement than HBM's complicated through-silicon-via construction. Micron is currently sampling GDDR5X in 11Gbps and 12Gbps flavors, too, which will yield up to 576GBytes/sec on a 384-bit bus.
