Nvidia Expands NVLink with Fusion Program and Launches DGX Cloud Lepton

At Computex 2025, Nvidia opened its NVLink interconnect to external CPUs and AI accelerators while unveiling a GPU rental marketplace to bolster its AI ecosystem.

Overview

  • Nvidia's NVLink Fusion program allows non-Nvidia CPUs and custom AI accelerators to integrate with its high-speed NVLink interconnect for rack-scale AI infrastructure.
  • Early NVLink Fusion partners include Qualcomm and Fujitsu for CPUs, and MediaTek, Marvell, Alchip, Synopsys, Cadence, and Astera Labs for accelerators and design tools.
  • NVLink delivers up to 14× the bandwidth of PCIe 5.0, enabling faster communication between GPUs and CPUs in AI data centers.
  • Rivals AMD, Intel, and Broadcom remain absent from the NVLink Fusion ecosystem, backing the open Ultra Accelerator Link standard instead.
  • Nvidia also launched DGX Cloud Lepton, a GPU compute rental platform, now in early access with support from multiple cloud providers offering tens of thousands of GPUs.
