Nvidia (NVDA.US) quickly denied it! Fubon says next-gen GPU Rubin may be delayed due to redesign

The Zhitong Finance App learned that Fubon Financial Holdings, a financial group in Taiwan Province of China, said in the latest research report that the Nvidia (NVDA.US) next-generation graphics processor Rubin's production process at TSM.US (TSM.US) may be delayed due to chip redesign.

Fubon analyst Sherman Shang said in a research report: “We think Rubin chips are likely to face delays. Although the first version of the design was filmed at the end of June, Nvidia is currently redesigning the chip to better match AMD (AMD.US)'s upcoming MI450 series products.”

Further analysis by Shang said, “Based on the latest progress, the redesigned chip is expected to be filmed in late September or October. Based on this time point estimate, shipments of Rubin chips will be limited in 2026.” In semiconductor manufacturing, flowsheet refers to the final stage of integrated circuit design delivery to fab production after verification.

Nvidia officially denied this. A company spokesperson said, “The content of this report is untrue, and the Rubin project is still progressing according to the original plan.”

Earlier, according to various sources, the Rubin chip was originally planned to be mass-produced at the end of 2025 and officially launched in early 2026.

Nomad Semi analyst Moore Morris revealed on social networking platform X that Rubin GPUs will take over the Blackwell architecture, which is currently in the process of climbing capacity. According to the data, shipments of Blackwell chips reached 750,000 in the first quarter of 2025 and increased to 1.2 million in the second quarter. It is expected to reach 1.5 million and 1.6 million pieces in the third and fourth quarters, respectively.

Morris also pointed out that currently AMD and Broadcom (AVGO.US) are the fastest-growing customers of TSMC's CoWoS (wafer-based chip) packaging technology. In 2025, Nvidia still dominates 51.4% of production capacity, with Broadcom and AMD accounting for 16.2% and 7.7% respectively. However, by 2026, Broadcom and AMD are expected to increase their share of production capacity to 17.4% and 9.2%, respectively, while Nvidia's share will drop slightly to 50.1%.
