Micron Starts Mass Producing GDDR5X Earlier Than Expected
In February 2016, Micron announced it will start mass producing GDDR5X memory chips by summer, but it seems that Micron is starting the production ahead of schedule.
Kristopher Kido, Director of Micron’s Global Graphics Memory Business, posted on official Micron Blog post:
Today, I am happy to announce that GDDR5X, the fastest discrete memory component in the world, has already entered mass production. With gaming and virtual reality driving continuous increases in performance requirements for GPUs, it’s a critical time to deliver higher memory bandwidth and efficiency, and GDDR5X is well positioned to help drive these new efficiencies.
Since the GDDR5X production is started, we can hope that the recently announced GTX 1080 will be available in sufficient quantity for purchase once its launched on June 10. GDDR5X memory is only featured in GTX 1080 while GTX 1070 features GDDR5 memory.
Micron said that it tasked a special team of graphic memory engineers with designing GDDR5X memory, and the end result you see today is the culmination of the thousands of hours of hard work.
It was rumored that Nvidia will ditch High Bandwidth Memory for GDDR5X memory for GTX 1080, and that is exactly how this happened. It is relatively easier to implement GDDR5X memory compared to HBM, and combine it with performance upgrade it offers over GDDR5, it is clear that Nvidia made the right decision.
Nvidia CEO Jen-Hsun Huang said during Pascal’s launch event:
This memory is so fast. It is so fast… G5x, the fastest GDDR5 memory in the world.
It is unclear that AMD will also use GDDR5X memory for it Polaris architecture. A recent road map shows HBM2 with Vega, which will launch in 2017. Right now, there no conformation that Polaris will use GDDR5 or GDDR5X memory, but we will know soon enough.
