SiFive To Integrate NVIDIA NVLink Fusion For Next-Gen AI Data Centers

In a move that could have major implications for future AI datacenters, SiFive, a leader in RISC-V processor IP, has announced a strategic partnership with NVIDIA to integrate NVIDIA’s NVLink Fusion interconnect technology into its forthcoming silicon platforms. This collaboration marks a significant shift for both companies and the broader AI ecosystem, which brings together SiFive’s customizable, power-efficient RISC-V processor IP with NVIDIA’s industry-leading NVLink scale-up interconnect and OCP MGX rack-scale architecture. NVLink Fusion, which was made available for third-party licensing in Q2 2025, enables high-bandwidth, low-latency, scale-up capabilities at the rack scale, with seamless integration of NVIDIA AI accelerators and the broader NVLink Fusion ecosystem. SiFive now joins other leaders in the space that have also adopted NVLink Fusion, but the partnership also paves the way for the RISC-V open source compute architecture as a whole.
