Following Nvidia's announcement of the new GTX 1080 with GDDR5X memory, Micron has now announced that its new GDDR5X memory has entered mass production, which suggest that there should be no supply constraints for the new generation GPUs.
According to Micron, GDDR5X memory will allow Nvidia to get an unprecedented level of memory bandwidth on the new Geforce GTX 1080 and is a result of thousands of hours of teamwork between those two companies.
The GDDR5X memory allows Nvidia to obtain a total memory bandwidth of 320GB/s on the GTX 1080 which is almost as high as the one seen on the GTX 980 Ti, despite the fact that the GTX 1080 has a narrower 256-bit memory interface.
AMD will also be using GDDR5X memory on its upcoming Polaris-based graphics cards, as it basically allows them to obtain higher memory bandwidth with a narrower memory interface and lower power consumption.
Currently, Nvidia uses 10Gbps GDDR5X chips but earlier report from Micron suggested that GDDR5X could reach a bandwidth of up to 12Gbps, so we will eventually see those chips as well.
