CRDO vs. MRVL: Which AI Connectivity Stock Has More Upside?

Credo Technology Group (CRDO) and Marvell Technology (MRVL) are benefiting from the AI-driven data center market, with CRDO forecasting over 85% revenue growth for fiscal year 2026 and Marvell reporting a 76% year-over-year increase in data center revenues for Q1, driven by custom AI silicon and electro-optics. CRDO's integrated approach and momentum in optical DSPs are expected to fuel growth, while Marvell's partnership with NVIDIA and focus on optical connectivity present significant opportunities. Despite trade tensions and margin pressures for Marvell, both companies are poised to capitalize on the increasing demand for high-speed connectivity solutions, with CRDO currently holding a stronger Zacks Rank.

Analysis

The rapid expansion of artificial intelligence is a primary growth catalyst for semiconductor firms specializing in high-speed data center connectivity, notably benefiting Credo Technology Group (CRDO) and Marvell Technology (MRVL). CRDO, characterized as a small-cap hypergrowth entity, demonstrated robust financial performance with fiscal 2025 revenues surging 126% year-over-year to $436.8 million and fourth-quarter revenues increasing 179.7% to $170 million, propelled by strong demand for its Active Electrical Cables (AECs) and optical Digital Signal Processors (DSPs). CRDO projects fiscal 2026 revenues to surpass $800 million, implying over 85% year-over-year growth, underpinned by its integrated system-level approach possessing the entire stack from SerDes IP to production, and innovations such as PCIe Gen6 AECs and 3-nanometer 200-gig-per-lane optical DSPs. In contrast, Marvell, a mid-cap leader, reported a 76% year-over-year rise in its first-quarter data center revenues to $1.44 billion, which accounted for 76% of its total revenues, driven by custom AI silicon, electro-optics, and next-generation switches; this segment is guided for mid-single-digit sequential growth in the fiscal second quarter. Marvell's strategic partnership with NVIDIA integrating NVLink Fusion and its advancements in Co-Packaged Optics are key strengths. Despite CRDO's strong stock performance (up 38.2% in the past month versus MRVL's 20.2%), it trades at a significantly higher forward price-to-sales ratio of 17.40X compared to MRVL's 7.36X. This valuation premium for CRDO is supported by significantly upwardly revised analyst estimates and a Zacks Rank #1 (Strong Buy), reflecting strong positive sentiment (0.8 per-ticker). Marvell carries a Zacks Rank #3 (Hold) with marginal upward estimate revisions and a more neutral sentiment (0.4 per-ticker), and faces headwinds from US-China trade tensions and gross margin pressures due to higher costs for custom AI silicon.

Key Decisions for Investors

• Investors should recognize the significant growth opportunities within the AI-driven data center infrastructure market, which serves as a primary tailwind for both Credo Technology and Marvell Technology, supported by an overall 'strongly positive' sentiment for this theme.
• Given Credo Technology's superior revenue growth (fiscal 2025 +126% YoY), strong fiscal 2026 outlook (over 85% YoY growth), significantly positive analyst estimate revisions, and favorable Zacks Rank #1, a more aggressive investment posture could be considered, though its higher price-to-sales ratio of 17.40X and small-cap nature warrant careful attention to valuation and market volatility.
• For Marvell Technology, which has a more diversified profile and a current Zacks Rank #3, investors might adopt a hold strategy, carefully monitoring its data center segment growth (Q1 +76% YoY), the impact of custom AI silicon manufacturing costs on gross margins, and exposure to US-China trade tensions before adjusting positions.
• Key factors to monitor for both entities include the pace of adoption for next-generation connectivity solutions like AECs and optical DSPs, hyperscaler capital expenditure trends, competitive positioning in high-speed interconnects, and the evolution of gross margins particularly for Marvell's custom AI silicon business.
