On July 19, 2023, Samsung has officially announced that it has completed the development of the industry’s first Graphics Double Data Rate 7 (GDDR7) DRAM. The South Korean tech giant will first install it in the next-generation systems of key customers for verification this year.
GDDR7 Key Specifications
- Bandwidth – 1.5-terabytes-per-second (TBps), which is 1.4 times that of GDDR6’s 1.1TBps
- Speed per pin of up to 32Gbps
- The changes are made possible by Pulse Amplitude Modulation (PAM3) signaling method
- 20% more energy efficient
“Our GDDR7 DRAM will help elevate user experiences in areas that require outstanding graphics performance, such as workstations, PCs and game consoles, and is expected to expand into future applications such as AI, high-performance computing (HPC) and automotive vehicles,” said Yongcheol Bae, Executive Vice President of Memory Product Planning Team at Samsung Electronics. “The next-generation graphics DRAM will be brought to market in line with industry demand and we plan on continuing our leadership in the space.”
