Micron Technology has announced the sampling of its next-generation GDDR7 graphics memory with the industry’s highest bit density.
Leveraging Micron’s 1β (1-beta) DRAM technology and architecture, Micron GDDR7 delivers 32 Gb/s high-performance memory in a power-optimised design. With over 1.5 TB/s of system bandwidth, which is up to 60 per cent higher bandwidth than GDDR6, and four independent channels to optimise workloads, Micron GDDR7 memory enables faster response times, smoother gameplay, and reduced processing times. GDDR7 also provides a greater than 50 per cent 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 per cent.
Micron GDDR7 memory offers performance that increases throughput by up to 33 per cent and reduces response time by up to 20 per cent for generative AI workloads such as text-to-image creation. Moreover, Micron expects that graphics cards built with GDDR7 will provide a greater than 30 per cent improvement in frames per second (FPS) for ray tracing and rasterisation over current GDDR6 and GDDR6X trends across 1080p, 1440 and 4K resolutions. For gaming applications, Micron GDDR7 memory enables AI-enhanced gameplay with adaptable landscapes, players, and storylines through performance and frame buffer scaling.
“Micron is once again at the forefront of memory innovation, developing the highest bandwidth solutions available, built with advanced process and interface technology to enable continued graphics performance leadership,” said Micron compute products group general manager and vice president Praveen Vaidyanathan. “The best-in-class capabilities of Micron GDDR7 memory help bring new levels of realism and performance to the most demanding applications.”
Micron GDDR7 memory will be available directly from Micron and through select global channel distributors and resellers in the second half of the calendar year 2024.
