The new GDDR5X memory standard has gotten one step closer to gamers and ordinary users with Micron now shipping the first working samples of the new memory standard. A while ago the US memory company promised it would mass produce GDDR5X this year and it might just keep its promise. The new memory has come into existence to replace the existing GDDR5 memory, while serving along with HBM and HBM2 memory, which will be kept only for high-end and enthusiast-class video cards.
Currently the company ships three versions of GDDR5X – MT58K256M32JA-100, MT58K256M32JA-110 and MT58K256M32JA-120. All of them feature a 256 Mbit x 32 design with memory density of 8 Gbit. The only difference is in the data transfer speed – the MT58K256M32JA-100, MT58K256M32JA-110 and MT58K256M32JA-120 transfer data at 10, 11 and 12 Gbit/sec, accordingly.
GDDR5X will function pretty much in the same way GDDR5 does but the new memory will offer twice the bandwidth. AMD and NVIDIA will unveil GDDR5X video cards by the end of the year.
