Key Takeaways:
Meta Platforms and Broadcom are significantly deepening their collaboration on custom AI chips, extending their partnership to 2029 in a move that strengthens Broadcom’s position in the AI accelerator market and advances Meta’s push for silicon independence. The multi-gigawatt deployment plan for Meta's custom chips signals a growing challenge to the dominance of third-party hardware providers like Nvidia.
"Meta is building our massive compute infrastructure with Broadcom, collaborating on the chip design, packaging, and networking," Meta Founder and CEO Mark Zuckerberg said in a statement. "We are creating the foundation for the personal superintelligence we are building for billions of people."
The expanded multi-generational agreement announced Monday will support the large-scale deployment of Meta’s custom Meta Training and Inference Accelerator (MTIA) chips. The initial phase commits to a deployment exceeding 1 gigawatt (GW), with plans for further multi-gigawatt expansion. As part of the deal, Broadcom President and CEO Hock Tan will transition from Meta's board of directors to a role as a strategic advisor, focusing on Meta's custom silicon roadmap.
The move underscores the immense infrastructure requirements for generative AI, with Meta aiming to embed real-time AI features across its platforms, including WhatsApp, Instagram, and Threads. For Meta, the custom MTIA chip, supported by Broadcom's full-stack technology, is a core pillar of its strategy to optimize performance and reduce total cost of ownership (TCO) by matching bespoke hardware to specific AI workloads, lessening its reliance on expensive, general-purpose GPUs. For Broadcom, whose stock rose 3.3% in after-hours trading on the news, the deal solidifies a long-term revenue stream and cements its XPU custom accelerator platform as a critical component for hyperscale AI.
The core of the partnership centers on Broadcom providing its XPU custom accelerator platform to support Meta's MTIA chips. This includes comprehensive support from chip design and advanced packaging to network interconnects. Broadcom's XPU platform integrates logic, memory, and high-speed I/O to create a scalable foundation for multiple generations of the MTIA chip.
While Meta's MTIA is primarily designed for inference and low-precision computing tasks, the scale of the planned deployment is significant. The initial 1 GW phase alone represents a massive investment in custom hardware, highlighting Meta's aggressive push to build out its AI infrastructure.
Beyond the custom silicon itself, Broadcom will supply its Ethernet networking solutions to connect the large-scale MTIA clusters. The agreement covers scale-up (in-rack), scale-out (across nodes), and scale-across (across domains) networking needs.
Broadcom’s portfolio of high-radix Ethernet switches, optical interconnects, and PCIe switches will form a low-latency network fabric based on standard protocols. This is crucial for eliminating network congestion in AI workloads that span tens of thousands of nodes. By using a standards-based Ethernet architecture, Meta aims to ensure efficient operation and lower TCO across the lifecycle of its multi-generational infrastructure.
Hock Tan's transition from a board member to a technical advisor signifies a shift in the relationship from a capital-level agreement to a deeply integrated technical and business collaboration. His advisory role will focus on guiding Meta's custom silicon roadmap and infrastructure investment strategy.
"This initial deployment of MTIA is just the beginning of a multi-generational roadmap," Tan stated. "It highlights Broadcom's unrivaled leadership in AI networking and the strength of our XPU custom accelerator platform."
