The Concentrated World of Chip Manufacturing
At the heart of the semiconductor industry’s complexity is an extremely concentrated supply chain. One of the most telling examples of this concentration is the global reliance on a single company, ASML in the Netherlands, for the supply of extreme ultraviolet lithography machines. These machines are crucial for producing advanced semiconductor chips, and without them, the march toward ever-smaller, more efficient, and powerful chips would stall.
Then, when it comes to manufacturing state-of-the-art semiconductors for the AI industry, it turns out that only a handful of companies worldwide have the capability to manufacture chips using the leading edge of today’s semiconductor technology. Among them, TSMC, Samsung, and Intel stand out. However, when we zoom in on the production of advanced chips using technologies below 7 nanometers (nm), only TSMC and Samsung are in the race, selling these cutting-edge chips to other firms. Yet, TSMC distinguishes itself even further as the sole entity capable of reliably producing the most advanced chips, such as Nvidia’s H100 GPUs, which are set to power the next generation of AI technologies.
TSMC’s monopolistic grip extends beyond Nvidia, encompassing the entire advanced AI chip market, including products for tech giants like Google, Amazon, Microsoft, AMD, and other credible alternatives, like Cerebras and SambaNova Systems.
The Financial Capacity Advantage
Producing semiconductors requires access to the purest metals, the deployment of the world’s most expensive and sophisticated machinery capable of etching features less than 100 atoms wide, and the employment of legions of specialized engineers. The production process is so sensitive that a single speck of dust can result in the scrapping of an entire batch of chips, leading to losses in the millions of dollars.
As a result, the financial barriers to entry in this sector are astronomical. For instance, in 2021, TSMC announced its plan to invest $100 billion over three years to expand its fabrication capabilities, highlighting the enormity of the capital expenditure required. The construction of its Fab 18, a facility legendary for producing the world’s most advanced chips, including Nvidia’s H100s, came with a $20 billion price tag. This level of investment has enabled TSMC to create a virtuous cycle of technological advancement and financial return. Companies seeking the pinnacle of chipmaking capabilities, from Apple to Tesla and Nvidia, inevitably turn to TSMC. This demand, in turn, fuels TSMC’s investments in further innovation, thereby perpetuating its leadership position.
Risks from the Potential China – Taiwan Conflict
The concentration of such a critical component of the global AI infrastructure in Taiwan poses a significant risk, magnified by the potential for geopolitical conflict in the region. Just recently, a top US admiral reported to Congress that China is building its military and nuclear arsenal on a scale not seen by any country since World War II and all signs suggest it’s sticking to ambitions to be ready to invade Taiwan by 2027. A China-Taiwan conflict could devastate the global AI ecosystem, a reality that underscores the precariousness of this single point of failure.
In response to these risks and as part of a strategic diversification effort, TSMC announced in late 2022 its plan to invest $40 billion in building two state-of-the-art fabrication plants in the United States, located in Arizona. The first facility should start production of 4-nanometer chips in the first half of 2025, while the launch of the second facility has been delayed and is expected not earlier than 2027. Despite the importance of this diversification move, the output of these U.S. fabs is projected to be less than 5% of TSMC’s total production.
Realizing the risks, the U.S. government provides further strategic support of semiconductor manufacturing through a massive $20 billion package to Intel. This initiative aims to facilitate the construction of advanced chip factories, enhance research and development, and enable the transformation of existing plants into cutting-edge facilities. The deal also puts the U.S. on track to produce 20% of the world’s most advanced AI chips by 2030.
NVIDIA: Pioneering AI Chip Design
With a better understanding of the concentration issues in the semiconductors manufacturing space, we can now turn our attention to the world of chip design, where NVIDIA has established an unrivaled dominance. The company secured an overwhelming majority of the AI chip market with estimates indicating it holds over 70 percent of sales. This dominance is underscored by the impressive volume of chips sold – 2.5 million units last year, each fetching an average price of around $15,000. A testament to NVIDIA’s pivotal role in the AI industry is its clientele, which includes tech giants like Microsoft and Meta; these companies alone accounted for approximately 25% of NVIDIA’s sales in the recent two quarters.
Clearly, the significant financial outlay to NVIDIA, coupled with a high degree of dependence on its technology, has left leading tech companies seeking alternatives. These firms are keen to reshape this dynamic, aiming for greater autonomy and reduced expenditure. However, transitioning away from NVIDIA’s ecosystem presents considerable challenges. We will explore the intricacies of this endeavor and understand the complexities involved.
The Ecosystem Advantage
NVIDIA’s GPUs have become synonymous with AI development, driving the creation and scaling of generative AI applications. The company’s success is underpinned by its CUDA platform, a software layer that enables developers to leverage NVIDIA’s hardware for AI and high-performance computing tasks. This platform has become the de facto standard for AI development, resulting in a significant barrier to entry for potential competitors.
Developers, researchers, and companies have invested heavily in software systems designed specifically for NVIDIA’s architecture. This investment encompasses code development, optimization, and workforce training, among other areas. Once these investments are made, the cost – both financial and operational – of switching to alternative platforms becomes prohibitive. This inertia benefits NVIDIA, creating a self-reinforcing loop where the more developers use NVIDIA’s chips and software, the more entrenched its position becomes.
Emerging Challenges and Competitors
Despite NVIDIA’s stronghold, the landscape is shifting. Efforts to standardize AI development across different hardware platforms are gaining traction, posing potential challenges to NVIDIA’s dominance. Initiatives like the UXL Foundation, which seeks to create an open-source software suite enabling AI code to run on any hardware, aim to reduce the industry’s dependency on a single vendor’s architecture. Such movements are backed by industry heavyweights, including Google, Intel, Qualcomm, and Arm, and strive for broad compatibility, threatening to disrupt NVIDIA’s ecosystem advantage.
Moreover, NVIDIA’s supremacy in AI chip design faces direct challenges from tech giants developing their own AI chips. Companies like Google, Amazon, Meta, and Microsoft are investing in proprietary chip technologies to reduce reliance on external suppliers and gain greater control over their AI infrastructure.
