Mizuho’s Asia hardware and semiconductor analysts have raised their 2025 forecast for Nvidia’s AI GPU shipments, projecting an 8-10% increase over their July 2024 estimates. The revision is driven by supply chain improvements, particularly advancements in CoWoS (Chip on Wafer on Substrate) technology.
Shipment Projections and CoWoS Technology
The report suggests that Nvidia (NASDAQ: NVDA) will ship between 6.5 and 7 million AI GPUs in 2025, including 3 million CoWoS-S units. These shipments will mainly consist of Nvidia's Hopper and Blackwell models, with CoWoS-S reaching yields of over 99%. Furthermore, Nvidia's CoWoS-L process is expected to produce between 3.8 and 4 million units, focusing on high-demand GB200 server racks, with around 80-90% of the production dedicated to this line.
TSMC's Production Expansion and Supply Chain Improvements
Mizuho’s revised forecast coincides with the expansion of Nvidia’s production partner, Taiwan Semiconductor Manufacturing (NYSE: TSM), which is doubling its annual wafer capacity. The report notes that CoWoS supply constraints are likely to continue into 2025 but are expected to ease as TSMC's annual wafer capacity surpasses 650,000, a 100% increase year-over-year. Additionally, to mitigate supply-demand pressures, some back-end (on-substrate) processes are anticipated to be outsourced to Advanced Semiconductor Engineering (ASE).
Blackwell GPU and Supply Chain Outlook
Mizuho analysts believe that concerns about potential delays in the rollout of Nvidia’s Blackwell GPUs are “exaggerated.” Both TSMC and SK Hynix Inc. (KS:000660) are expected to achieve sales growth following the planned launch of Blackwell GPUs in the fourth quarter of 2024.
Overall, Mizuho analysts do not foresee any significant delays in semiconductor production, including AI GPUs and ASICs, impacting AI server manufacturing in 2025. They also note that Taiwanese back-end equipment vendors, such as Allring Tech, are likely to benefit from TSMC's efforts to localize its supply chain.
