Upgraded Nvidia RTX 5090 gets 128GB VRAM and $13,000 price tag — 'super limited' GPU is described as a 'prototype'

A modified Nvidia RTX 5090 GPU with an impressive 128GB of VRAM has surfaced, priced at around $13,200, significantly higher than the standard model. This custom GPU is considered a prototype due to its use of GDDR7X memory, not widely available yet. The mod involves intricate custom PCB designs to accommodate the increased memory capacity. Despite the high price tag, the modded GPU demonstrates the potential for enhanced memory configurations beyond what is currently offered by manufacturers. Buyers should be cautious of fraudulent sales of modified GPUs on secondhand markets.
