Beyond Nvidia: Three AI Infrastructure Stocks Poised for Superior Growth Through 2028

The Shifting Landscape of AI Infrastructure

The artificial intelligence (AI) infrastructure market is experiencing unprecedented growth, with Nvidia firmly established as the industry leader. However, as the world's largest company by market capitalization, Nvidia may face diminishing returns compared to smaller peers in the sector. As the article notes, "as the world's largest company, its stock may not have as much upside as some others in the space." Consequently, investors are looking toward three specific stocks that could outperform Nvidia over the coming years.

Broadcom: The Architect of Custom Silicon

The AI infrastructure market is witnessing a decisive shift toward custom AI chips, a trend that significantly benefits Broadcom (NASDAQ: AVGO). As a leader in application-specific integrated circuit (ASIC) technology, Broadcom provides the essential blueprints and intellectual property required to transform customer chip designs into manufacturable physical products.

Broadcom played a pivotal role in Alphabet's development of its highly successful Tensor Processing Units (TPUs), creating a sustained tailwind for the company. Furthermore, other hyperscalers, including Meta Platforms and OpenAI, have turned to Broadcom to develop their own custom AI ASICs. The financial outlook is robust: "Broadcom projects it will generate more than $100 billion in AI chip revenue alone in fiscal 2027, which is about five times the total AI revenue it produced in fiscal 2025." Additionally, its ASIC business bolsters its data center networking division, where it leads with Ethernet technology via its Tomahawk solution.

Advanced Micro Devices: Strategic Partnerships and CPU Dominance

Positioned as the distant No. 2 player in the graphics processing unit (GPU) market behind Nvidia, Advanced Micro Devices (NASDAQ: AMD) possesses significant growth potential due to its smaller revenue base. Two major partnerships with OpenAI and Meta Platforms are expected to serve as primary drivers for this expansion.

Under these agreements, both customers have committed to purchasing 6 gigawatts of GPUs from AMD, necessitating the integration of AMD's ROCm software platform into their data centers. In return, "both customers will receive warrants representing up to 10% of the ownership in AMD, with vesting contingent on deliveries and AMD's share price." This structure incentivizes OpenAI and Meta to support AMD's success in the inference market.

However, the most significant growth driver for AMD may lie in the data center central processing unit (CPU) market, where it currently holds the leadership position. While GPUs provide computational muscle, CPUs act as the brain; with the rise of agentic AI, demand for high-performance CPUs to coordinate data flow and logic will surge.

Micron Technology: Undervalued Memory Solutions

Micron Technology (NASDAQ: MU) shares recently paused after reporting exceptional fiscal second-quarter results. Despite this, the company remains a top contender in the AI infrastructure space, trading at a forward price-to-earnings (P/E) ratio of below 4.5 times fiscal 2027 analyst estimates.

This low valuation reflects the historically cyclical nature of the memory business. Yet, for GPUs and other AI chips to perform optimally, they require high-bandwidth memory (HBM), a specialized form of DRAM. While Samsung and SK Hynix are also major players, Micron is securing long-term stability by moving away from traditional one-year agreements. "Micron recently confirmed that it has signed its first five-year strategic customer commitment, marking a major shift from its traditional one-year agreements." Although Micron lacks Nvidia's technological moat, it rides the same secular tailwinds, suggesting the valuation gap between them may narrow.

Investment Context and Disclosures
