Samsung‘s new GDDR7 memory modules are now available, and more options with higher capacities and faster speeds will be released over time. Currently, 3GB modules are available for purchase in China. These modules are primarily used in the RTX 5090 laptop graphics cards, which offer 24GB of VRAM with a 256-bit bus. However, these modules can also be used to upgrade current desktop graphics cards.
Upgrading the RTX 5090 with 48GB Memory
With the availability of these 3GB GDDR7 modules, it’s now possible to replace the 32GB memory on the RTX 5090 desktop models with 48GB. This configuration is not entirely new, as NVIDIA’s RTX PRO 6000 model already uses 3GB modules to achieve a total of 96GB (48GB per side).
Future Upgrades and SUPER Models
For users looking for even more memory, they can buy these new modules and swap them into their current RTX 50 series cards to increase their memory capacity. A new SUPER version of the current generation is also expected, offering more memory. For example, the RTX 5080 SUPER could have 24GB using these 3GB modules, the RTX 5070 SUPER could reach 18GB, and the RTX 5060 could increase to 12GB.
However, it seems like it’s still too early to think about the SUPER models, as NVIDIA has not yet finished the current RTX 50 series. The final model of this generation, RTX 5050, is expected to be presented in July.
