SiFive to Power Next-Gen RISC-V AI Data Centers with NVIDIA NVLink™ Fusion

Proven high-performance SiFive compute platforms gain coherent, high-bandwidth connectivity with NVIDIA NVLink Fusion to NVIDIA GPUs and other accelerators, enabling scalable and energy-efficient AI infrastructure.

Santa Clara, CA -- January 15, 2026 -- 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.

SiFive’s power-efficient and highly customizable compute solutions are designed specifically for this shift. By combining wide, out-of-order cores with scalable coherent fabrics and advanced memory hierarchies, SiFive enables cloud providers and system vendors to tailor their CPUs to exact workload requirements while also maintaining the software portability that comes with the RISC-V ecosystem.

With the addition of NVIDIA NVLink Fusion, SiFive computing platforms can connect directly to NVIDIA GPUs and accelerators using a coherent, high-bandwidth interconnect to reduce latency, share data more efficiently, and improve overall system utilization for large-scale AI deployments.

“AI infrastructure is no longer built from generic components, it is co-designed from the ground up,” said Patrick Little, President and CEO of SiFive. “By integrating NVLink Fusion with SiFive’s high-performance compute subsystems, we’re enabling customers with an open and customizable CPU platform that pairs seamlessly with NVIDIA’s AI Infrastructure to deliver exceptional efficiency at data center scale.”

“With SiFive, we’re bringing our coherent, high-bandwidth NVLink interconnect to the RISC-V ecosystem,” said Jensen Huang, founder and CEO of NVIDIA. “This provides the flexibility to combine customizable RISC-V CPUs with NVIDIA accelerators to build scalable, power-efficient and specialized AI infrastructure – and move from innovation to deployment faster than ever.”

NVLink Fusion provides a unified interconnect fabric capable of coherently linking CPUs, GPUs, and custom accelerators at extremely high bandwidth. For SiFive customers, this means faster integration cycles, simpler system design, and the ability to scale AI performance without being constrained by traditional CPU-to-accelerator bottlenecks.

By aligning its long-term roadmap with NVIDIA NVLink Fusion, SiFive is enabling next-generation AI architectures that combine open-compute, energy efficiency, and the world’s leading acceleration technologies. “The adoption of NVlink Fusion reflects a broader industry shift toward heterogeneous, co-designed systems where open CPU architectures and advanced interconnects work together to define the future of AI data center computing,” Little added.
