Apple is facing significant challenges in securing chip production capacity from TSMC, its primary manufacturing partner, as competition intensifies with Nvidia. TSMC's CEO, CC Wei, informed Apple last year of substantial price increases, marking a shift in power dynamics between the two companies. Apple's once-dominant position on TSMC’s client list is waning; sources suggest that Nvidia may have surpassed Apple in client rankings for at least part of last year. As demand for AI chips surges, the footprint required for each GPU has increased, squeezing Apple's access to TSMC's production capabilities. In 2023, TSMC reported a 36% revenue increase to $122 billion, while Nvidia's sales are expected to rise 62%. In contrast, Apple’s product revenue is predicted to grow by only 3.6% through December 2025. The demand for high-performance computing, driven largely by AI, is outpacing growth in the smartphone market. TSMC's sales from its AI segment rose 48%, while smartphone revenue grew just 11%. This trend is likely to continue, with TSMC's capital expenditure projected to reach $56 billion as it expands production to meet AI demand. TSMC is advancing its technology roadmap with new chips like the 2-nanometer (N2) and the upcoming A16, which aims to cater to high-performance computing needs. Although Apple remains a significant customer due to its diverse chip portfolio, the immediate focus on AI by companies like Nvidia and AMD has shifted the industry's landscape. TSMC's business model emphasizes building new fabs for new technologies, which helps maintain output but also means that older technologies remain in production longer. While Apple's breadth of manufacturing at TSMC provides some stability, the current AI boom could alter the balance of power in the chip manufacturing sector, leading to potential challenges for Apple in the near future.
