Micron has officially discontinued its entire 2GB GDDR7 memory product line, marking these chips as End of Life (EOL). The affected models include both 28Gbps and 32Gbps variants, specifically the MT68A512M32DF-28:A chip previously used in some GeForce RTX 50 series graphics cards.
Following this decision, Micron will focus its GDDR7 production on 3GB capacity modules. However, these 3GB chips are not direct replacements for the 2GB versions, as current RTX 50 series card designs are optimized for 2GB modules. Using 3GB chips complicates product design and results in irregular memory configurations.
The 3GB GDDR7 modules currently command significantly higher prices than the 2GB versions. Industry reports suggest that high costs associated with 3GB memory have contributed to the slow development of NVIDIA's planned RTX 50 SUPER series, making them an impractical alternative for mainstream consumer graphics cards in the near term.
With Micron exiting the 2GB market, the supply chain for RTX 50 series memory will rely more heavily on Samsung Electronics and SK Hynix. While these two manufacturers currently maintain sufficient supply capacity to prevent immediate shortages, the loss of a supplier could still impact market balance.
Looking ahead, the industry is preparing for the next generation of memory technology. Multiple manufacturers are planning to introduce 4GB and 6GB GDDR7 modules between 2027 and 2028. These high-density chips are expected to debut alongside NVIDIA's upcoming Rubin GPU platform to support AI and high-end computing needs.
