According to Samsung, the development of GDDR7 will be completed on July 19, 2023. First of all, it will be introduced to the next-generation system of a major customer and will be verified in 2023.

Samsung has a track record of developing the industry's first 24Gbps GDDR6 DRAM.

Samsung's GDDR7 features a data transfer rate of up to 32 Gbps per pin, achieving a figure of 1.5 TBps, which exceeds the bandwidth of GDDR6, 1.1 TBps. This figure is made possible by adopting PAM3, which can send 50% more data than Non Return to 0 (NRZ).

GDDR7 is 20% more power efficient than GDDR6 thanks to power-saving design technology optimized for high-speed operation. There is also an option for low voltage operation especially for power sensitive applications such as notebook PCs.

In addition, by optimizing the IC architecture and using an epoxy molding compound (EMC) with high thermal conductivity, the thermal resistance is 70% lower than GDDR6, enabling stable performance under high-speed operating conditions. It is said that it became like this.

Bae Yong-chul, executive vice president of Samsung's memory product planning team, said, 'Our GDDR7 DRAM will help improve the user experience in areas that require superior graphics, such as workstations, PCs, and game consoles. It is expected to expand into future applications such as high-performance computing (HPC), automotive, etc. Next-generation graphics DRAMs will be brought to market in line with industry demand, and Samsung will continue its leadership in this area. I plan to,' he said.
