SK hynix has introduced that it’s going to start mass manufacturing of GDDR7 modules within the third quarter of this yr (July-September). The brand new modules supply sooner bandwidth and improved energy effectivity.
GDDR7 can ship 32Gbps per pin and SK hynix says that this will attain 40Gbps “depending on the circumstances”. When used on high-end GPUs with 384-bit reminiscence buses, the brand new reminiscence modules will have the ability to switch 1.5TB per second (in comparison with 1.1TB per second for the earlier technology).
Moreover, SK hynix managed to enhance the facility effectivity by “more than 50%” in comparison with the earlier technology, due to improved packaging expertise. It elevated the variety of heat-dissipating layers from 4 to 6, which led to 74% decrease thermal resistance (all whereas sustaining the identical bodily dimensions).
The “G” in “GDDR” stands for “Graphics”, however the firm expects that its modules will see use in different fields too. Sangkwon Lee, Head of DRAM Product Planning & Enablement at SK hynix, stated that “GDDR7 is expected to be adopted by a wider range of applications such as high-specification 3D graphics, AI, high-performance computing and autonomous driving.”
