SiFive is adopting NVIDIA NVLink Fusion in its RISC-V compute platforms to enhance connectivity with NVIDIA GPUs and accelerators, aiming for scalable AI infrastructure. This integration allows for coherent, high-bandwidth connections, reducing latency and improving system utilization for AI workloads.

NVLink Fusion provides a unified interconnect fabric linking CPUs, GPUs, and accelerators, enabling faster integration and simplifying system design. SiFive's designs include support for NVLink, facilitating custom CPU development while aligning with industry trends towards heterogeneous systems. The technology offers up to 3.6 TB/s chip-to-chip bandwidth, reflecting a shift in data center computing architecture.
