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

A factory in China has modded an RTX 5090 to sport an insane 128 GB of VRAM, quadruple the amount found in a regular 5090. They've achived so by using a custom PCB and prototype GDDR7 memory that currently no one makes. The card reportedly costs around 13,000 with expectedly limited availability.
