Against the backdrop of the ongoing AI boom, China is once again demonstrating its path to high performance. According to insider I_Leak_VN, local factories have begun to modify NVIDIA GeForce RTX 5090 video cards, increasing the amount of video memory to 128 GB — four times the standard configuration. Such devices are already on sale for about $13,200, which is more than six times the recommended cost of the original model.
Modified versions are produced in a handicraft way: the chip and memory are removed from the original RTX 5090, after which the components are installed on custom printed circuit boards with support for double-sided mounting of microcircuits. This design allows you to bring the volume up to 128 GB. According to the source, we are talking about prototypes with non-standard GDDR7X chips and firmware that are not officially supported.
NVIDIA has nothing to do with the release of these models — they are created and sold on a semi-legal basis, mainly for AI farms and data centers, where memory is critical. For gaming tasks, this configuration is redundant, but in the context of limited access to professional GPUs, especially in Asia, such “Frankensteins” find their buyer.
Despite the high price, it looks explainable. The RTX PRO 6000 Blackwell with 96 GB of video memory costs about $10,000. The RTX 5090 version with 128 GB will cost 33% more — but it also has a third more memory.
