Apple just joined a consortium of Big Tech companies to challenge Nvidia’s closed AI hardware ecosystem

Apple has joined the Ultra Accelerator Link Consortium as a board member, marking its formal entry into an industry-wide effort to develop next-generation AI accelerator connectivity standards.

Key development: Apple has secured a board position in the Ultra Accelerator Link (UALink) Consortium, a group of over 65 members working to establish open standards for AI hardware connectivity.

• Becky Loop, Apple’s Director of Platform Architecture, emphasized the company’s commitment to addressing connectivity challenges and expanding AI capabilities through this collaboration
• The consortium includes major tech players such as AWS, Google, Meta, Microsoft, AMD, and Intel
• Apple’s involvement will enable the company to influence the development and adoption of these new standards

Technical context: UALink represents an open alternative to Nvidia’s proprietary NVLink technology, which currently dominates GPU-to-GPU communication in data centers.

• UALink aims to create an open standard for connecting multiple AI accelerators in data center environments
• The technology competes with Nvidia’s NVLink and Infiniband communication technologies
• A parallel initiative called Ultra Ethernet is also challenging Nvidia’s dominance in data center connectivity

Specifications and timeline: The UALink Consortium has outlined specific technical goals and release schedules for its technology.

• The initial 1.0 version specification will support 200Gbps connections
• The technology will enable linking up to 1,000 accelerators within an AI pod
• The specification is based on the IEEE P802.3dj PHY Layer
• Contributor Members will receive access to specifications in 2024
• Public release is scheduled for the first quarter of 2025

Strategic implications: Apple’s entry into the UALink Consortium signals a broader industry push toward open standards in AI hardware infrastructure, potentially reshaping the competitive landscape in data center connectivity.

• This move could help reduce dependency on Nvidia’s proprietary technologies
• The collaboration of major tech companies suggests a unified approach to challenging Nvidia’s market position
• The development of open standards could accelerate innovation and reduce costs in AI infrastructure

Market dynamics: The formation of industry consortiums like UALink reflects growing concerns about single-vendor dominance in critical AI infrastructure components, while highlighting the increasing importance of AI hardware optimization for major tech companies.
