Nvidia - Nvidia is the leading company in AI chips, primarily through its graphics processing units (GPUs), which are essential for training large language models and running AI inference [2][5] - The company holds over 80% market share in the GPU space, largely due to its CUDA software platform, which allows developers to utilize its chips for various tasks beyond gaming [3][4] - Nvidia's GPUs are critical for AI infrastructure, as demand for AI models continues to grow, necessitating increased computing power [5] - The stock is currently attractively valued, trading at a forward price-to-earnings (P/E) ratio of 27 times 2025 analyst estimates and a price/earnings-to-growth (PEG) ratio of about 0.5, indicating potential undervaluation [6] Broadcom - Broadcom contributes to AI infrastructure through its networking technology, providing essential components like switches and network interface cards (NICs) that facilitate data transfer between GPUs and servers [7] - The company is a leader in ethernet switching technology, benefiting from the increasing demand for high-bandwidth, low-latency switches as AI clusters expand [8] - Broadcom also develops custom chips, known as application-specific integrated circuits (ASICs), for AI, which can outperform standard GPUs in specific tasks while consuming less power [9] - The company has established a serviceable addressable market of $60 billion to $90 billion for its AI chip customers by fiscal year 2027, with a current AI revenue run rate of approximately $16 billion [11] - Broadcom's valuation has dropped to a forward P/E ratio of just over 29, which may be considered inexpensive if it captures a significant share of the AI market opportunity [12]
