Micron GDDR7 utilizes 1β (1-beta) DRAM technology and novel architecture to provide 32 Gb/s high-performance memory in a power-optimized design. With over 1.5 TB/s of system bandwidth, which is up to 60% faster than GDDR6, and four independent channels to optimize workloads, Micron GDDR7 memory allows for faster response times, smoother gameplay, and faster processing. GDDR7 also improves power efficiency by more than 50% over GDDR6[4], leading to improved thermals and longer battery life, while the new sleep mode saves standby power by up to 70%. Advanced reliability, availability, and serviceability (RAS) characteristics on Micron GDDR7 improve device dependability and data integrity without sacrificing performance, expanding Micron GDDR7’s applications to include AI, gaming, and high-performance computing workloads.

Micron GDDR7 memory delivers outstanding performance, increasing throughput by up to 33% and reducing response time by up to 20% for generative AI tasks like text-to-image creation. Furthermore, Micron anticipates that GDDR7 graphics cards will give a more than 30% increase in frames per second (FPS) for ray tracing and rasterization over current GDDR6 and GDDR6X trends at 1080p, 1440, and 4K resolutions.With the launch of GDDR7, Micron now has an industry-leading product portfolio for edge AI inference applications on CPU, NPU, and GPU components, including DDR, LPDDR, and GDDR memory options. Micron GDDR7 memory allows for AI-enhanced gameplay with adaptive environments, players, and storylines thanks to 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’s vice president and general manager of the Compute Products Group, 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 has continually achieved world-class performance and quality throughout the past five years of successful high-volume GDDR6X manufacture. These similar characteristics, combined with established technology, design, and testing experience, will help to speed GDDR7 acceptance and provide full spectrum support for the product’s manufacturing ramp. Micron announced PAM4 signaling on GDDR6X, which improved leadership performance by more than 20% over GDDR6.[8] The success of PAM4 serves as the foundation for Micron’s continuing GDDR7 portfolio leadership with PAM3. Engineering improvements, such as measuring the industry’s first 40 Gb/s PAM3 performance, open the way for better performance in future GDDR7 products.

The ecosystem collaborates on the Micron GDDR7 memory solution.

“At AMD, we are dedicated to creating the most immersive gaming experiences. Our collaboration with Micron on GDDR7 promotes our common aim,” stated Joe Macri, senior vice president and corporate fellow at AMD. “We are excited about Micron’s launch of GDDR7, and we look forward to leveraging this technology to make gaming even more responsive and lifelike.” “Cadence has a strong history of collaboration with Micron to develop industry-leading memory IP subsystem solutions for GDDR, HBM, DDR, and LPDDR,” said Boyd Phelps, Cadence’s senior vice president and general manager of the Silicon Solutions Group.

“We are using samples of Micron’s leading 1β DRAM technology-based GDDR7 to test and validate GDDR7 PHY IP operating at speeds up to 36 Gb/s.” Micron GDDR7 memory will be available directly from Micron and through select global channel distributors and resellers in the second half of 2024.
