On June 4th, Micron announced the launch of the next generation graphics memory chip GDDR7 sample with the highest density in the industry, using Micron 1 β DRAM technology and innovative architecture. This product provides a 32Gb/s pin bandwidth through power optimization design, with a system bandwidth of over 1.5TB/s, which is 60% higher than GDDR6. At present, the product has been displayed on the official website of Micron, with an I/O voltage of 1.2V and an available capacity of 16Gb.
Micron GDDR7 improves energy efficiency by over 50%, allowing for better heat dissipation and extending the battery life of mobile devices; The product has a brand new sleep mode, which can reduce standby power consumption by 70%. In addition, the Micron GDDR7 is equipped with high availability and maintainability (RAS) features, which enhance device reliability and data integrity without affecting performance, helping to extend GDDR7 applications to artificial intelligence (AI), gaming, and high-performance computing (HPC) workloads.
According to the official introduction, the performance improvement of Micron GDDR7 can increase the throughput of AI workloads (such as Wensheng Graph) by 33% and shorten response time by 20%. In addition, Micron expects that GDDR7 graphics memory can improve ray tracing and rasterization frame rate (FPS) of 1080P, 1440P, and 4K resolution games by more than 30% compared to current GDDR6 and GDDR6X. In addition to the game field, GDDR7 is also suitable for edge computing reasoning and other applications.
Micron also released the eye diagram of the industry's first 40Gb/s PAM3 signal modulation method. GDDR7 successfully achieved high bandwidth data transmission using PAM3, allowing the industry to continue expanding graphics performance to higher speeds.
AMD stated that their collaboration with Micron in GDDR7 has advanced their common goals and they are very excited to use this technology to make the game more realistic. EDA software company Cadence stated that it has a long history of cooperation with Micron, helping to develop system solutions for GDDR, HBM, DDR, and LPDDR.
