Chipmaker Nvidia’s (NVDA) next-generation Rubin graphics processing unit (GPU) may face production delays at Taiwan Semiconductor Manufacturing Company (TSM) due to a redesign, according to Taiwanese financial firm Fubon Financial. Indeed, analyst Sherman Shang explained that the first version of Rubin was completed in late June, but Nvidia is now making adjustments to better compete with AMD’s (AMD) upcoming MI450 GPU. Shang expects the revised version to be finalized in late September or October, which could reduce Rubin’s production volumes in 2026.

It is worth noting that Rubin is set to replace Nvidia’s current Blackwell line, which continues to see impressive growth. In fact, Nomad Semi analyst Moore Morris noted that Blackwell GPU shipments totaled 750,000 units in Q1 2025, increased to 1.2 million in Q2, and are projected to reach 1.5 million and 1.6 million units in Q3 and Q4, respectively. However, competition for advanced packaging capacity at TSMC is intensifying.
Morris pointed out that AMD and Broadcom (AVGO) are the fastest-growing customers for TSMC’s CoWoS (Chip-on-Wafer-on-Substrate) technology. While Nvidia still leads with a 51.4% share in 2025, compared to Broadcom’s 16.2% and AMD’s 7.7%, its share is projected to dip slightly to 50.1% in 2026. At the same time, Broadcom and AMD’s shares are expected to climb to 17.4% and 9.2%, respectively. Originally, Rubin was slated for mass production in late 2025 with retail availability in early 2026, but the redesign could push that schedule back.
