Arm Joins Nvidia’s NVLink Fusion to Link Neoverse CPUs Directly to Nvidia GPUs

The partnership targets hyperscalers seeking simpler, coherent CPU–GPU integration for custom AI infrastructure.

Overview

  • Announced at Supercomputing ’25, Arm will integrate NVLink IP so licensees can build CPU SoCs that connect to Nvidia accelerators over a coherent fabric instead of PCIe.
  • Nvidia says the move reduces design complexity, cuts development costs, and speeds time to market for specialized server builds.
  • The expansion brings NVLink Fusion support to two major microarchitecture developers and four CPU developers overall, according to Tom’s Hardware.
  • Hyperscalers including Microsoft, Amazon, and Google are developing or deploying Arm-based CPUs, positioning them to pair those chips with Nvidia GPUs.
  • Nvidia already sells Grace Blackwell, which couples multiple GPUs with an Nvidia Arm CPU, and it agreed to invest $5 billion in Intel to enable NVLink with Xeon as part of a broader multi-vendor strategy.
