Arm and Nvidia announced at the Supercomputing '25 conference that Arm had joined the NVLink Fusion ecosystem, marking a major advance for the technology, which is now supported by two major microarchitecture developers and four CPUs developers in total. For Nvidia, this means that Arm's customers will develop processors that can work with Nvidia's AI accelerators, whereas Arm will also be able to design CPUs that could compete against Nvidia's own or Intel processors in Nvidia-based systems.
"Arm is integrating NVLink IP so that their customers can build their CPU SoCs to connect Nvidia GPUs," said Dion Harris, the head of data center product marketing at Nvidia. " With NVLink Fusion, hyperscalers can significantly reduce design complexity, save development costs, and reach the market faster. The addition of Arm customers provides more options for specialized semi-custom infrastructure."
