시장 분석은 브로드컴과 마벨을 맞춤형 AI 칩 설계 및 네트워크 인터커넥트 기회에서 최우선 경쟁사로 비교한다.

Application-specific integrated circuits (ASICs) are custom chips engineered for specific tasks, and demand for them has surged amid the artificial intelligence infrastructure boom. Because custom AI processors are designed exclusively for dedicated workloads, they deliver exceptional efficiency, outperforming general-purpose hardware like graphics cards in both energy consumption and processing speed. This operational cost advantage explains why major hyperscalers and AI firms have increasingly turned to in-house processor development.

Marvell Technology (NASDAQ: MRVL) and Broadcom (NASDAQ: AVGO) stand among the leading providers of custom AI chips, a position that has fueled their rapid expansion. To determine which semiconductor stock offers greater upside for investors seeking exposure to this high-growth sector, a comparative analysis of their business fundamentals is necessary.

Counterpoint Research projects that Broadcom will command 60% of the custom AI chip market by 2027. Marvell operates as a formidable challenger, capturing an estimated 20% to 25% share. Broadcom’s dominant market position directly correlates with its accelerated growth trajectory. In the third quarter of fiscal 2026, which concluded on August 2, Broadcom reported an 86% year-over-year revenue increase to $29.6 billion. The company attributed this top-line expansion primarily to a 221% surge in AI semiconductor revenue, which reached $16.7 billion.

This robust revenue growth propelled earnings per share up 96% year over year to $3.32. Looking ahead, Broadcom anticipates AI chip revenue to climb another 236% year over year in the current quarter, reaching $21.7 billion. This momentum stems from a deep roster of enterprise clients, including OpenAI, Anthropic, Meta Platforms, and Alphabet’s Google. Crucially, Broadcom expects this AI-driven growth to extend well beyond fiscal 2026. The company forecasts AI chip revenue to rise 186% in fiscal 2026 to $58 billion, nearly double that figure to $115 billion in fiscal 2027, and potentially reach $230 billion by fiscal 2028. Correspondingly, Broadcom projects earnings per share could exceed $30.00 in fiscal 2028, a substantial leap from its estimated fiscal 2026 EPS of $11.64.

Marvell, by contrast, reported a 37% year-over-year revenue increase to $2.74 billion in the second quarter of fiscal 2027, which ended on August 1. Earnings per share also grew healthily by 40%. While Marvell’s growth metrics are solid, Broadcom’s figures underscore how its market leadership provides a more pronounced competitive advantage. Furthermore, Marvell’s forward guidance indicates it will not match Broadcom’s growth rate in the near term. The company expects revenue to jump 45% in fiscal 2027 to $12 billion, followed by a 50% increase in fiscal 2028. Management notes that its custom AI division is positioned to more than double in fiscal 2028 and will “accelerate significantly in fiscal 2029.”

While the expanding custom AI chip market serves as a clear tailwind for Marvell, Broadcom’s market dominance grants it a distinct edge. A valuation comparison further reinforces the case for Broadcom. As of this writing, Marvell stock has rallied 163% in 2026, whereas Broadcom has lagged with gains of just 3%. This relative underperformance suggests the market has yet to fully price in Broadcom’s exceptional growth trajectory, rendering it significantly cheaper on a multiple basis. Historical earnings trends indicate Broadcom’s EPS could expand faster than Marvell’s over the long term. Consequently, investors weighing these two AI plays face a straightforward decision: Broadcom’s combination of accelerated growth and discounted valuation presents a compelling opportunity, while Marvell’s comparatively slower growth may pressure shares following its strong 2026 run.

Before committing capital to Broadcom, investors should consider additional context. The Motley Fool Stock Advisor analyst team recently identified what they consider the ten best stocks to purchase immediately, and Broadcom was notably excluded. The selected ten could generate substantial returns in the coming years. For historical reference, when Netflix appeared on this list on December 17, 2004, a $1,000 investment at the time of recommendation would have grown to $421,997.* Similarly, when Nvidia was added on April 15, 2005, the same $1,000 investment would have appreciated to $1,413,876.*

It is worth noting that Stock Advisor’s total average return stands at 978%, representing significant outperformance against the S&P 500’s 213% return.
