Manufacturers are reportedly preparing to launch 4 GB and 6 GB GDDR7 memory chips between 2027 and 2028. This development aims to increase VRAM capacity in GPUs without requiring changes to the existing PCB layout or memory bus width.
Currently, a 128-bit graphics card using four 2 GB modules is limited to 8 GB of VRAM. With the introduction of 4 GB chips, this capacity could reach 16 GB, while 6 GB modules would allow for 24 GB on the same interface. For a 256-bit bus with eight packages, the capacity could scale to 32 GB or 48 GB.
High production costs and strong demand for current 3 GB GDDR7 chips have reportedly impacted the release of models like the RTX 5050 9 GB and the RTX 50 Super series. The industry expects that 4 GB modules may become a practical standard for mainstream cards, while 6 GB chips will likely target workstation hardware.
While these memory chips are expected in the 2027–2028 window, there is no official confirmation regarding their integration into specific future product lines from NVIDIA or AMD.
