Meta Orders Custom AMD MI450 Accelerators With 144GB HBM4 Memory

According to MLQ.ai, Meta has submitted orders for custom AMD MI450 AI accelerators, marking the latest sign of large technology companies pursuing tailored AI silicon.

The custom MI450 accelerators feature 144GB of HBM4 high-bandwidth memory, approximately one-third of the standard memory configuration. This memory profile suggests Meta may have optimized the chips for specific inference or training workloads rather than maximizing general-purpose memory capacity.

The choice of HBM4 memory is notable. As the next-generation high-bandwidth memory standard, HBM4 offers significant bandwidth and power efficiency improvements over current HBM3e. AMD's adoption of HBM4 in the MI450 demonstrates its aggressive roadmap in high-performance AI computing.

Meta has previously collaborated with AMD on silicon, including deploying AMD EPYC processors in its data centers. This custom MI450 order deepens that partnership and reflects Meta's strategy of diversifying its AI infrastructure investments.

For AMD, landing a custom order from a hyperscale customer like Meta represents significant market validation for its AI product line. While NVIDIA still dominates the AI chip market, AMD is gaining ground through customization and differentiation.

The order also carries competitive implications for NVIDIA. When a major customer like Meta begins customizing AMD chips, it signals the AI infrastructure supply chain is diversifying away from reliance on a single general-purpose accelerator vendor.

The MI450 accelerators are expected to be deployed in Meta's AI inference and training clusters, though specific deployment timelines have not been announced.
