Nvidia Weighs Radical Idea: Less Rubin Ultra Chip Memory

Nvidia is weighing a radical step to deal with a shortage of advanced high-bandwidth memory chips: using less of it than planned in its next-generation graphics processing unit, the Rubin Ultra.

Over the past few weeks, Nvidia has been testing at least three versions of the Rubin Ultra GPU, some of which have less memory than what the company initially announced, according to three people with direct knowledge of the trial. Nvidia is considering the lower-memory versions partly because it may not be able to secure enough advanced memory to supply its original design, according to the three people.
