Nvidia Is Opening Its NVLink Technology to Others: But Is That Bullish or Bearish for the Stock?

Nvidia announced NVLink Fusion, opening its high-speed NVLink interconnect technology to systems beyond Nvidia's own chips, including custom ASICs and non-Grace CPUs. This move aims to expand Nvidia's networking market and potentially address the rising adoption of custom AI accelerators by cloud giants, where Nvidia faces competition and margin pressure. While this could lead to incremental revenue, it also signals a potential acknowledgment of slower GPU hypergrowth and market share loss to lower-cost ASICs in the long term.

Analysis

Nvidia's introduction of NVLink Fusion at Computex, opening its NVLink interconnect technology to non-Nvidia chipsets such as custom ASICs and third-party CPUs, marks a pivotal strategic adjustment. This initiative is interpreted as a dual strategy: firstly, to stimulate its data center networking segment, which saw a 9% year-over-year revenue decline last quarter, starkly contrasting with the 116% growth in its data center semiconductor revenue. Secondly, and perhaps more significantly, it serves as a defensive response to the increasing adoption of custom AI accelerators by cloud giants, who can achieve substantial cost savings (around 75% reduction on chip costs compared to Nvidia GPUs, pre-R&D). Market data from The Information Network projects custom ASIC market share in AI to rise from 22% in 2023 to 30% by 2025, while GPU share is expected to contract from 72% in 2023 to 65% in the current year. By allowing NVLink integration with these custom solutions, involving partners like Marvell Technologies, Fujitsu, and Qualcomm, Nvidia aims to capture incremental revenue and maintain relevance in systems even if they don't use its GPUs. This move, while potentially beneficial for expanding its addressable market, also implicitly acknowledges the competitive pressures and potential moderation of its GPU hypergrowth and high-margin dominance, despite a robustly growing overall AI infrastructure market and Nvidia's current software lead.

Key Decisions for Investors

• Investors should carefully track Nvidia's networking revenue in upcoming earnings reports to gauge the adoption rate and financial impact of NVLink Fusion.
• This strategic shift suggests a need to temper long-term expectations for Nvidia's GPU-centric hypergrowth and current margin levels, given the increasing competition from cost-effective custom ASICs.
• Consider the potential positive impact on partners like Marvell Technologies (MRVL), Fujitsu, and Qualcomm (QCOM), as their involvement in NVLink Fusion could enhance their role in the AI hardware ecosystem.
• Monitor the development and adoption of competing open-source interconnect standards, such as UALink and technologies from the Ultra Ethernet Consortium, as these pose a challenge to Nvidia's networking segment expansion.
