Samsung's latest 32Gbps GDDR7 will further enhance applications such as artificial intelligence, high-performance computing and automotive
GDDR7 delivers 1.4x performance improvement and 20% more energy efficiency compared to previous generation 24Gbps GDDR6
Today, Samsung Electronics announced that it has completed the development of its industry-first GDDR7. It will be validated on the next-generation systems of key customers within the year, driving future growth in the graphics card market and further consolidating Samsung Electronics' technology position in the field.
Samsung GDDR7 Graphics Memory
Following Samsung's development of GDDR6 16Gb at 24 gigabits per second (Gbps) in 2022, the GDDR7 16Gb product will offer the highest speed of Samsung's graphics memory to date at 32 Gbps. At the same time, innovations in integrated circuit (IC) design and packaging technology have improved performance stability at high speeds.
Samsung's GDDR7 products will help enhance the user experience for those who require high-performance graphics memory, such as workstations, personal computers and gaming consoles, and are expected to expand into artificial intelligence, high-performance computing and automotive," said Yongcheol Bae, executive vice president of Samsung's Memory Product Planning Team. The new generation of graphics memory will be brought to market based on demand, and we hope to continue to maintain our cutting-edge technological capabilities in this area."
Notably, Samsung's GDDR7 achieves an outstanding 1.5 terabits per second (TBps) of bandwidth, 1.4 times that of GDDR6's 1.1 TBps, and up to 32 Gbps per data I/O (input/output) port rate.The product utilizes a Pulse Amplitude Modulation (PAM3) signaling method, replacing the Non-Return to Zero (NRZ) signaling method of its predecessors, which results in a This results in a significant increase in performance. The PAM3 signaling method can transfer up to 50% more data than the NRZ signaling method in the same signaling period.
In addition, GDDR7 is designed with energy-saving technologies suitable for high-speed operation, improving energy efficiency by 20% compared to GDDR6. For power-conscious devices such as laptops, Samsung offers a low operating voltage option.
To minimize memory chip heat generation, in addition to integrated circuit (IC) architecture optimization, Samsung uses epoxy molding compound (EMC) materials with high thermal conductivity in the packaging materials. These improvements not only significantly reduce thermal resistance by 70% compared to GDDR6, but also help GDDR7 achieve stable performance even at high operating speeds.
