SK hynix unveils GDDR7 memory that’s faster and more energy efficient than its predecessor | Infinium-tech
SK Hynix has announced that it will begin mass production of GDDR7 modules in the third quarter (July-September) of this year. The new modules offer faster bandwidth and improved power efficiency.
GDDR7 can deliver 32Gbps per pin and SK hynix says it can reach up to 40Gbps “depending on conditions.” When used on high-end GPUs with 384-bit memory buses, the new memory modules will be able to transfer up to 1.5TB per second (compared to 1.1TB per second for the previous generation).
Additionally, SK hynix managed to improve power efficiency by “more than 50%” compared to the previous generation, thanks to improved packaging technology. It also increased the number of heat dissipating layers from four to six, leading to 74% lower thermal resistance (all while maintaining the same physical dimensions).
The “G” in “GDDR” stands for “graphics,” but the company expects its modules to be used in other areas as well. “GDDR7 is expected to be adopted by a wide range of applications such as high-specification 3D graphics, AI, high-performance computing and autonomous driving,” said Sangkwon Lee, head of DRAM product planning and enablement at SK hynix.
