According to DAI Magister, NPUs disrupting Nvidia AI dominance have emerged as their main rival. The semiconductor market, driven by Generative AI, is worth over $600 billion and is expected to hit $1 trillion by 2030. Nvidia leads with its high-performance GPUs, but their cost and energy use raise sustainability concerns.
The semiconductor market is projected to reach around $400 billion by 2030*, with AI semiconductors expected to constitute over 30% of this market, up from 20% today. AI has recently dominated headlines with the launch of ChatGPT, Claude, and a host of other GenAI platforms. This has prompted countless companies to examine how they can implement AI into their products, from robotics and security cameras to smart factories and electrical vehicles. However, this integration poses challenges. The processes required to implement AI algorithms overwhelm the small central processing units (CPUs) found in many devices, and the graphics processing units (GPUs) that are capable of handling them are large, expensive, and energy-intensive. This problem has given rise to a new type of chip: the neural processing unit, or NPU.
NPUs disrupting Nvidia AI dominance
NPUs are engineered to accelerate the processing of AI tasks, including deep learning and inference. They can process large volumes of data in parallel and swiftly execute complex AI algorithms using specialized on-chip memory for efficient data storage and retrieval. While GPUs are more versatile and can handle a wider range of tasks beyond AI, offering higher performance in terms of raw computing power, NPUs are domain-specific processors optimized for executing AI tasks efficiently. Consequently, NPUs can be smaller, less expensive, and more energy efficient than their GPU counterparts. Counterintuitively, NPUs can also outperform GPUs in specific AI tasks due to their specialized architecture.
Key NPU applications include enhancing efficiency and productivity in industrial IoT and automation technology, powering technologies such as infotainment systems and autonomous driving in the automotive sector, and enabling high-performance smartphone cameras, augmented reality (AR), facial and emotion recognition, and fast data processing. In data centres and machine learning/deep learning (ML/DL) environments to train AI models, NPUs are increasingly being integrated to complement GPUs, especially in scenarios requiring energy efficiency and low latency.
Despite efforts from companies like Microsoft, AWS, and Google to develop their own AI GPU and NPU chips, Nvidia remains the undisputed leader in the AI hardware market due to the superior performance and established ecosystem of their GPUs. This “race for AI” does emphasize performance, but Nvidia’s dominance in the GPU space overshadows two fundamental issues: high capex/operating costs and energy consumption related to running AI.
AI usage incurs significant economic costs
The deployment and maintenance of AI systems involve considerable financial investment. Training sophisticated AI models such as OpenAI’s GPT-4.0, requires extensive computational resources. Sam Altman himself stated that training GPT-4.0 cost over $100 million. These expenses cover the procurement of high-performance GPUs, cloud computing services, and data storage, alongside the costs of specialized human expertise in data science and engineering.
Additionally, operational costs continue to accrue post-deployment. Companies need to ensure continuous updates, maintenance, and monitoring of AI systems to keep them functional and secure. This requires hiring skilled personnel, investing in cybersecurity measures, and regularly upgrading hardware to keep up with the ever-growing data and processing demands. As a relevant reference point, Epoch AI found that the cost of the computational power required to train the most powerful AI systems has doubled every nine months.
AI drives high energy consumption
A single search query on Google, which relies on less computationally intense algorithms, uses approximately 0.3 Wh (watt-hours) of energy. In contrast, a query to an AI model like GPT-4.0 consumes significantly more energy due to the complexity and size of the model. Although precise figures for GPT-4.0 are not readily available, it is estimated that such AI queries consume up to 10 times more energy than a standard Google search. The environmental impact of AI is becoming a growing concern which is driving the development of more energy-efficient algorithms and hardware.
Initiatives are underway to mitigate the costs and carbon footprint of AI whilst remaining competitive with Nvidia’s performance, despite their market dominance and inherent capital expenditure (capex) barriers to entry.

Edge inference: Cost-effective, energy-efficient alternative to server processing
The uses of AI semiconductors are bifurcated into training and inference applications. Whilst training occurs on GPUs in data centers, with Nvidia holding an astonishing 98% market share, inference can be performed on servers or edge devices. Put simply, the AI chip market can be divided into a 2×2 matrix as follows:
The AI-related NPU edge device market, estimated to reach $50 billion by 2026, is particularly noteworthy due to its emphasis on low power consumption, efficiency, and zero latency. Edge AI inference is driven by the need for enhanced data security, as reducing reliance on cloud servers minimizes the risk of data breaches. Moreover, edge devices offer real-time data processing, zero latency, and autonomy, enhancing overall performance. Cost savings are another significant factor, as minimizing dependence on costly cloud AI services can result in significant reductions in the total cost of ownership. Furthermore, reduced power consumption and carbon emissions align with environmental, social, and governance (ESG) goals.
