NVIDIA GDDR7 Chips: 4GB and 6GB Options Planned for 2027

Hardware enthusiasts tracking NVIDIA’s memory roadmap should watch for a shift in chip density that could reshape mid-range and workstation GPU designs. Supply chain reports suggest the company plans to introduce 4GB and 6GB GDDR7 memory modules by 2027 or 2028. This move matters because current consumer cards rely heavily on 2GB chips, while 3GB modules remain scarce and expensive. Higher density chips would allow manufacturers to build larger VRAM configurations with fewer physical components.

New densities could reshape mid-range and workstation GPU designs

NVIDIA currently uses 2GB GDDR7 chips as the mainstream standard for consumer graphics cards. The 3GB variant exists but stays limited to select high-end products like the RTX 5090 Laptop GPU and the RTX PRO 6000 workstation card. The rumored RTX 5050 9GB configuration, which would have used three 3GB chips, appears canceled due to the high cost of those modules. This cancellation highlights the pricing pressure that the new 4GB and 6GB chips aim to alleviate.

• Planned Densities: 4GB and 6GB
• Availability Window: 2027 or 2028
• Current Standard Density: 2GB (mainstream), 3GB (limited)
• Potential Configurations: 16GB with four 4GB chips; 24GB with four 6GB chips; 32GB with eight 4GB chips
• Current High-Density Usage: RTX 5090 Laptop GPU, RTX PRO 6000

The new 4GB chips would enable 16GB VRAM configurations using only four memory packages. Six-gigabyte modules could provide 24GB of VRAM on a 128-bit interface. Eight 4GB chips would support 32GB of VRAM on a 256-bit interface. These configurations offer a more efficient path to high memory capacities without requiring the expensive 3GB parts.

An anonymous industry analyst told Weibo source Golden Pig Upgrade that GDDR7 will remain a standard for the foreseeable future. The analyst stated, "The GDDR7 is here to stay for long, I'm sure we will see RTX 60, Radeon Next and perhaps even RTX 70 products using this memory type." This suggests the memory type will outlast the current generation of GPUs. We looked at NVIDIA RTX PRO 5500 Blackwell Listed in our earlier Nvidia coverage.

The 4GB and 6GB GDDR7 chips are not yet available and remain unconfirmed by NVIDIA. The timeline of 2027 or 2028 is based on supply chain rumors rather than official announcements. The cancellation of the RTX 5050 9GB SKU is also believed but not officially confirmed. Buyers should treat these specifications as reported plans until the company releases further details.
