SK hynix Inc. Introduces Industry-Leading GDDR7 Graphics Memory

SK hynix Inc. announced today that it has launched the top-performing GDDR7, a cutting-edge graphics memory product. The development of GDDR7 in March comes in response to the increasing demand from global customers in the AI sector for DRAM products that offer specialized performance for graphics processing and high speed. The company plans to begin mass production in the third quarter.

The new product boasts an operating speed of 32 Gbps, a 60% improvement over the previous generation, with the potential to reach speeds of up to 40 Gbps depending on the application. When used in high-end graphics cards, the product can process data at a rate exceeding 1.5 TB per second, equivalent to streaming 300 Full-HD movies (5 GB each) in just one second. SK hynix has also enhanced power efficiency by over 50% compared to the previous generation by implementing new packaging technology to address heat-related issues resulting from the rapid data processing.

The company has increased the number of heat-dissipating substrate layers from four to six, and has incorporated EMC into the packaging material to reduce thermal resistance by 74% compared to the previous generation, all while maintaining the product's size.

Sangkwon Lee, Head of DRAM Product Planning & Enablement at SK hynix, stated that GDDR7 is expected to find applications in a wide range of fields such as high-spec 3D graphics, AI, high-performance computing, and autonomous driving. "We are committed to solidifying our position as the leading provider of AI memory solutions by further enhancing our premium memory lineup," Lee added.
