Micron readying 3GB GDDR7 modules

Micron has officially entered the high-density graphics memory market with the introduction of its 3GB GDDR7 modules, joining Samsung and SK Hynix in providing memory modules of this capacity for the next wave of high-performance GPUs. Confirmed via a technical blog post, Micron's new ICs operate at a blistering 36 Gbps, representing a 12.5% speed increase over the initial 32 Gbps GDDR7 modules that debuted last year.

While this falls short of Samsung's flagship 42.5 Gbps chips and SK Hynix's upcoming 48 Gbps roadmap, Micron's 36 Gbps (Micron's blog via Wccftech) ceiling is strategically positioned to meet the actual real-world requirements of today's retail hardware.

The timing of this launch is critical, as the industry is currently grappling with a NAND flash and memory shortage. By becoming a third supplier of 3 GB modules, Micron provides much-needed relief to GPU manufacturers' supply chains. Currently, 3 GB GDDR7 chips are primarily used in specialised hardware such as the RTX 5090 Laptop GPU and the RTX Pro 6000 Blackwell workstation cards.

However, the 3 GB density is widely expected to become the new standard for the rumoured RTX 50 Super series, potentially allowing cards like the RTX 5070 Super and 5080 Super to offer expanded VRAM pools (such as 12 GB or 24 GB) without requiring wider memory buses. That is, however, if Nvidia decides to release them.

KitGuru says: Micron's entry into the 3GB space is less about winning the race and more about ensuring it doesn't get left behind during the AI craze. While Samsung and SK Hynix lead in memory speed, Micron is providing exactly what the market needs right now: a stable, high-capacity module that aligns perfectly with GPU manufacturers' plans. For gamers, the most exciting takeaway is that 3 GB modules make “8GB of VRAM” look increasingly like a relic of the past, paving the way for a much more generous mid-range standard later this year.
