ARM Embraces NVIDIA NVLink Fusion to Strengthen Neoverse Compute Ecosystem
Arm’s decision to license NVLink IP allows its Neoverse-based CPU designs to communicate directly with NVIDIA GPUs, bypassing traditional interconnects like PCIe.
ARM is integrating NVIDIA’s NVLink Fusion into its Neoverse architecture — a move that could significantly deepen collaboration between Arm CPU developers and NVIDIA’s high-performance GPU infrastructure.
“Arm and NVIDIA are working together to set a new standard for AI infrastructure,” said Rene Haas, CEO, Arm. “Extending the Arm Neoverse platform with NVIDIA NVLink Fusion brings Grace Blackwell-class performance to every partner building on Arm — a milestone that reflects the incredible momentum we’re seeing in the data center.”
NVLink Fusion, announced by NVIDIA in May 2025, is a scalable interconnect technology that enables non-NVIDIA CPUs and ASICs to connect directly to NVIDIA GPUs over a high-bandwidth, coherent link.

Industry experts see this as a potential watershed: by combining Arm’s energy-efficient Neoverse cores with NVIDIA’s GPU compute, data center operators could build highly efficient, tightly integrated AI systems.
“NVLink Fusion is the connective fabric of the AI era — linking every CPU, GPU and accelerator into one unified rack-scale architecture,” said Jensen Huang, founder and CEO of NVIDIA. “Together with Arm, we’re extending this vision across Neoverse to empower innovators everywhere to design the next generation of specialised AI infrastructure.”
For NVIDIA, this broadens its NVLink ecosystem beyond its own Grace CPU line-up — reinforcing its role as a central player in next-gen AI data centers. Arm, meanwhile, gains greater appeal among cloud providers and custom silicon designers who value both energy efficiency and performance.
As adoption of NVLink Fusion grows, companies like Marvell, Alchip, MediaTek, and Astera Labs are already on board — creating an ecosystem where Arm’s Neoverse chips can power tightly coupled, high-bandwidth AI platforms alongside NVIDIA GPUs.
