Micron Unveils New 24Gb GDDR7 DRAM with 36Gbps Data Rate for GPUs and AI Chips

Micron is not the first vendor to launch 3GB GDDR7 modules. Samsung and SK Hynix released comparable products as early as last year, with even higher data rates: 42.5Gbps for Samsung and 40Gbps for SK Hynix. SK Hynix is also developing a next‑generation GDDR7 module targeting 48Gbps.

Although Samsung and SK Hynix offer higher‑speed 3GB GDDR7 solutions, NVIDIA has not adopted such extreme speeds in its current products. The fastest implementation so far is 30Gbps in the GeForce RTX 5080, while other models feature 28Gbps or lower.

Theoretically, such high speeds offer limited practical benefits at the current stage, and Micron’s 3GB GDDR7 module has arrived relatively late to the market. Nevertheless, amid the challenging conditions in the DRAM market, a third supplier of 24Gb GDDR7 DRAM remains highly valuable for NVIDIA and other manufacturers, as it expands supply options and improves supply chain flexibility.

Rumors indicate that the upcoming GeForce RTX 50 SUPER series — initially planned to include the RTX 5080 SUPER, RTX 5070 Ti SUPER, and RTX 5070 SUPER — will widely adopt 3GB modules. However, recent DRAM price hikes and supply shortages have put these mid‑cycle upgrades at risk of cancellation. At the very least, they are unlikely to launch within this year.
