RTX 5090 SUPER May Get 48GB GDDR7
Disassembling the RTX PRO 6000 Blackwell revealed an unexpected fact: NVIDIA Starts Using 3GB GDDR7 Chips, previously considered experimental. Marking memory K4VCF325ZC from Samsung operates at up to 28 Gbps and is installed on a board with GPU The GB202-870 is a near-complete version of the RTX 5090 chip, suggesting that future versions RTX 5090 SUPER Will Be Able to Get 48GB of Video Memory, RTX 5080 SUPER - 24GB, without changing the number of microcircuits.
Previously, 3GB of GDDR7 was used only in the RTX 5090 Mobile, where 8 chips provided 24 GB. The video card was spotted at the ASUS booth during Computex 2025, as well as in the StorageReview review. At the same time, all current desktop RTX 50 use 2GB GDDR7 chips (K4VAF), and the maximum capacity is limited to 32 GB. However, the PCB of the GB202-based models already natively supports 3GB GDDR7 - this is confirmed by engineering videos and the official NVIDIA video released 4 months ago.
Physically the ability to upgrade to 3GB GDDR7 is already implemented in existing RTX 5090 and RTX 5080 boards, you just need to change the STRAP configuration and provide access to the chips. According to unconfirmed reports, NVIDIA held back the release of such configurations due to a lack of new memory. Now that 3GB of GDDR7 are already installed in the RTX PRO 6000, we can expect that RTX 5090 SUPER (48GB) and RTX 5080 SUPER (24GB) announced - it's just a matter of time.
