Advanced Micro Devices vs. Marvell Technology: Which Artificial Intelligence Stock Is a Better Buy Going into 2027?
The race for artificial intelligence dominance is shifting from experimental software to heavy-duty hardware. Investors deciding between Advanced Micro Devices (AMD +7.32%) and Marvell Technology (MRVL +9.33%) must determine which niche offers the better long-term return.
AMD is a direct competitor in the high-end processor market, challenging incumbents with its CPU and AI-focused GPU semiconductor chips. Marvell specializes in data infrastructure, providing the connectivity and storage solutions that keep information moving within modern data centers. Both companies are essential players in the expanding digital economy, though they serve different corners of the tech stack among semiconductor stocks.
The case for Advanced Micro Devices
AMD designs high-performance computing products for data centers, gaming, and embedded systems. It serves major hyperscale customers like Microsoft and is expanding its compute-for-equity partnership with Meta Platforms. Recently, the company secured a multiyear partnership with OpenAI to deploy its Instinct MI450 series AI accelerators in massive data center environments.
In the fiscal year ended Dec. 27, 2025, revenue reached $34.6 billion, representing growth of 34.3% compared with the prior fiscal year. This expansion helped the company achieve net income of $4.3 billion for the period. Its net margin, which measures the percentage of revenue remaining after all expenses are paid, was 12.5%.
As of its December 2025 balance sheet, the debt-to-equity ratio was 0.1x, a metric that compares total debt to shareholder equity to show reliance on borrowed money. The current ratio, which measures the ability to pay short-term debts with liquid assets, was 2.9x. For the fiscal year ended Dec. 27, 2025, free cash flow was $6.7 billion, though stock-based compensation (SBC) represented 21.2% of operating cash flow, which inflates reported cash generation since SBC is a non-cash expense added back in the cash flow statement.
The case for Marvell Technology
Marvell Technology operates as a fabless semiconductor company, designing hardware for data centers and communications networks. Its product line includes custom chips and storage controllers for high-speed connectivity. The company serves major cloud providers and has expanded its portfolio through the acquisition of Celestial AI and an agreement to acquire Lumentum Holdings.
In its latest annual report, filed for the fiscal year (FY) ended Jan. 31, 2026, revenue reached $8.2 billion. This was a significant increase of 42.1% year over year, resulting in net income of $2.7 billion. Its net margin hit 32.6% for the period, marking a significant shift in profitability compared to the losses reported in previous fiscal years.
Based on its January 2026 balance sheet, the debt-to-equity ratio was 0.3x, while the current ratio was 2.0x to indicate sufficient liquidity for short-term needs. Free cash flow for the fiscal year ended Jan. 31, 2026, was $1.4 billion. Note that stock-based compensation represented 33.8% of operating cash flow.
Risk profile comparison
Advanced Micro Devices faces intense competition from Intel and Nvidia, especially following their recent strategic partnership. The company relies heavily on a limited number of manufacturing partners, creating vulnerability to supply chain disruptions. Additionally, strict government export restrictions on advanced AI chips to certain markets have resulted in inventory charges and limit future market access.
Marvell Technology contends with revenue concentration, as a significant portion of sales comes from a small group of large distributors and direct customers. Like many peers, it depends on third-party foundries in the Pacific Rim, creating risks from geopolitical tensions or regional natural disasters. The company also faces pressure from major cloud providers developing their own proprietary chips, which could reduce long-term demand for its custom products.
Valuation comparison
Based on the Forward P/E, which compares price to future earnings estimates, and the P/S ratio, Marvell Technology appears to be the more attractively valued option.

Which stock would I buy for 2027?
AMD and Marvell have become powerhouses amid the artificial intelligence boom. AMD’s business is firing on all cylinders, as illustrated by its Meta partnership, announced Oct. 27, a $2.5 billion investment in Anthropic stock, and its $13.4 billion in fiscal Q3 sales, representing a 45% year-over-year increase. Even so, I would buy Marvell Technology stock going into 2027.
Because of AMD’s streak of successes in the AI sector, and the recently-revealed investigation into chief rival Nvidia’s CEO by that company’s Board of Directors, shares of AMD have become pricey, as Wall Street shifts away from GPU market leader Nvidia. This makes Marvell stock the better value, evidenced by both its forward earnings and sales multiples.
Marvell is also delivering spectacular results. During its investor day on Oct. 6, management shared updated revenue guidance that exceeded Wall Street expectations. The company raised sales in its 2028 fiscal year, which ends Jan. 31, 2028, to $20 billion, up from its prior guidance of $18 billion, and well above the $8.2 billion generated in FY 2026. It also set a FY 2031 revenue target of $70 billion to $90 billion.
Those figures were before Marvell announced it was acquiring Lumentum, a fast-growing optical components provider seeing massive demand due to AI’s need for speed. Lumentum’s sales of $1.3 billion for its fiscal Q1, ended Sept. 26, represented an impressive 137% year-over-year increase. With Lumentum, Marvell is poised to deliver strong growth in the coming years.
