Summary
Nvidia has reportedly canceled its planned quad-die Rubin Ultra GPU (four compute chiplets) for 2027 due to manufacturing execution concerns, opting instead for a dual-GPU design that is easier to produce. The ambitious Rubin Ultra was intended to double performance over the original Rubin architecture, but complexity and manufacturability issues led to the decision. The report, from SemiAnalysis, highlights the challenges Nvidia faces in pushing chiplet-based GPU architectures to extreme levels of integration.
