GDDR – Graphics Double Data Rate memory – DRAM from graphics computing units (GPUs). Micron makes GDDR6 memory which pumps out data at 616GB/s of bandwidth to a GPU. Its GDDR7 product, sampling in June 2024, delivers 32 Gb/s of high-performance memory, and has over 1.5 TB/s of system bandwidth, which is up to 60% higher bandwidth than GDDR6, and four independent channels to optimize workloads. Its GDDR7 also provides a greater than 50% power-efficiency improvement compared to GDDR6 to better thermals and lengthen battery life, while the new sleep mode reduces standby power by up to 70%.
