SiFive, the industry leader in high-performance RISC-V processor IP and compute subsystems, today announced it is adopting and integrating NVIDIA NVLink Fusion in its high-performance data center-class solutions, expanding options for building tightly integrated AI systems based on the RISC-V open instruction set architecture. As artificial intelligence workloads continue to redefine the requirements of modern data centers, system architects are increasingly seeking open, customizable compute platforms that can scale efficiently alongside advanced acceleration.

AI-driven computing is entering a phase where architectural flexibility and power efficiency are as critical as peak throughput. Training and inference workloads are growing faster than power budgets, forcing data center operators to rethink how CPUs, GPUs, and domain-specific accelerators are connected and orchestrated. In this environment, performance per watt and data movement efficiency have become first-order design constraints.
