    Scorpio X-Series Shipping

    late 2025
    CurrentPreproduction volumes
    TargetBegin shipping for customized scale-up architectures

    Why it matters

    Scorpio X-Series is expected to be a major growth driver, significantly increasing silicon dollar content per AI accelerator.

    We look for Scorpio X-Series to begin shipping for customized scale-up architectures in late 2025, with a shift to high-volume production over the course of 2026.

    Q&A highlights

    8

    What are the key differentiators for Scorpio X-Series, and how does it drive higher attach rates for other Astera products and COSMOS software?

    Scorpio's success stems from customer closeness, execution track record, and the COSMOS software suite. COSMOS enables customization for performance (lower latency, higher throughput) and diagnostics. Scorpio acts as an anchor socket, leading to opportunities for Aries and Taurus products in the same platforms, especially for X-Series which leverages PCIe derivatives for optimized performance.

    “So with the use of COSMOS, we can customize our products to deliver higher performance which translates to sometimes lower latency, sometimes higher throughput, sometimes different diagnostic features for our customers.”

    Detailed Narrative

    01

    Q2 Performance Highlights and Product Ramps

    Astera Labs reported strong Q2 FY25 results, with revenue reaching $191.9 million, marking a 20% sequential increase and 150% year-over-year growth. This performance was driven by both signal conditioning and switch fabric product lines. Notably, the Scorpio P-Series switches, supporting PCIe 6 scale-out applications, ramped into volume production and contributed over 10% of total revenue, becoming the fastest-ramping product in company history. Aries 6 solutions also began volume ramp, and Taurus demonstrated strong growth from AEC demand.

    02

    AI Infrastructure 2.0 Vision and Market Opportunity

    The company is actively pursuing the transition to what it terms 'AI Infrastructure 2.0,' characterized by open standards-based AI rack-scale platforms, broad innovation, interoperability, and a diverse multi-vendor supply chain. This transition is expected to create a significant market opportunity, with scale-up connectivity for rack-scale AI infrastructure alone projected to add nearly $5 billion by 2030. Astera Labs aims to be an anchor solution partner, leveraging its expertise across various interconnect protocols.

    03

    Scorpio Product Family and Growth Trajectory

    The Scorpio family, including both P-Series and X-Series, is central to Astera Labs' growth strategy. The P-Series, designed for scale-out connectivity, has seen broad customer adoption and is expected to exceed 10% of FY25 revenue. The X-Series, targeting scale-up networking for XPU-to-XPU connectivity, is engaged with over 10 unique AI platform and cloud infrastructure providers. It is expected to begin shipping in late 2025 and enter high-volume production in 2026, becoming the largest product line due to higher dollar content per AI accelerator.

    04

    UALink Momentum and Open Ecosystem

    Astera Labs is a leading promoter of UALink, an open standard for scale-up connectivity. The company highlighted UALink's robust performance potential, open ecosystem, and multi-vendor supply chain as key differentiators. Early industry momentum is strong, with multiple hyperscalers and compute platform providers exploring its integration. Astera Labs is committed to developing a broad portfolio of UALink solutions, anticipating its proliferation in 2027 and beyond as a significant long-term growth vector.

    05

    Strategic Partnerships and Ecosystem Expansion

    The company expanded strategic relationships to support its vision. Collaborations include NVIDIA for NVLink Fusion, Alchip Technologies for custom ASIC development in AI rack-scale infrastructure, and AMD for showcasing UALink. Industry progress in CXL was also noted, with SAP, Microsoft, and Intel utilizing CXL memory expansion for database optimization. These partnerships aim to foster an open, interoperable ecosystem for AI deployments.

    06

    General Compute and CXL Opportunities

    Beyond AI-specific applications, Astera Labs is tracking opportunities in general-purpose compute. The release of AMD's Venice CPU, supporting PCIe Gen 6, presents new design opportunities for Aries retimers and Taurus modules. The Leo CXL controllers, designed for memory expansion, are also seeing increased relevance as CPUs supporting CXL technology become ready for deployment, indicating future growth in this segment.
