According to SemiAnalysis reports covered by Tom's Hardware, Nvidia has cancelled its quad-die Rubin Ultra GPU in favor of a dual-GPU design due to manufacturing execution concerns (Tom's Hardware). The cancellation effectively halves the compute capability of Nvidia's next-generation AI accelerator, making it less competitive against AMD's Instinct MI500 series. The move also reduces demand for advanced packaging and HBM4E, potentially affecting TSMC's packaging capacity and memory suppliers. For AMD, this alleviates a major competitive threat and opens opportunities in the AI GPU market. The information is unofficial but corroborated by industry sources.
AMD is already up +158% over the recent 30-90 day window.
