Current NVIDIA GeForce RTX 5090 graphics cards utilize 2 GB GDDR7 memory modules. While 3 GB versions exist, their high production costs have limited widespread adoption in the market.
According to reports from Weibo leaker Golden Pig Upgrade, manufacturers are developing 4 GB and 6 GB GDDR7 chips. These components are expected to be available within the 2027 to 2028 timeframe.
The introduction of higher-density chips could significantly increase VRAM capacity without requiring changes to PCB layouts or memory bus widths. For instance, a 128-bit card could reach 16 GB or 24 GB of memory.
Supply chain sources cited by Videocardz indicate that current 3 GB modules are expensive, which has impacted the development of the rumored RTX 5050 9 GB model and potential RTX 50 Super series refreshes.
If 4 GB chips achieve lower production costs at scale, they may become the standard for mainstream GPUs. Meanwhile, 6 GB modules are likely to be prioritized for workstation and high-memory graphics cards.
