Custom RISC-V compute solutions for datacenter compute and infrastructure in the agentic AI era

SiFive’s RISC-V Solutions are Ideal for the Datacenter

AI is driving new workloads, such as SLMs, agentic AI, and enterprise RAG, that are ideal for CPUs. SiFive RISC-V solutions deliver the open, power-efficient, and customizable foundation needed for full-stack AI optimization..

Economical AI at Scale: Lower your cost per query and slash total cost of ownership (TCO) with high-density, power-efficient architectures engineered for demanding memory, power, and cooling requirements.
Workload-Tailored Hardware: Break free from rigid, single-vendor roadmaps and tailor silicon and software stacks directly to your specific AI inference use cases.
Full-Stack Innovation & Security: Accelerate time-to-deploy with open-source APIs, and protect your supply chain with a vendor-independent hardware strategy. Whether you are scaling public cloud infrastructure or managing highly regulated enterprise data, WorldGuard and RVA23 deliver the standardized, zero-trust hardware foundation required to protect against the most sophisticated threats.

SiFive Performance Family 2U Development Platform

SiFive Datacenter Solutions

Compute

SiFive high-performance CPU compute complexes, including the P870-D, are designed for modern AI workloads. The Intelligence family adds vector and matrix processing engines for training and inference, enabling flexible subsystem integration.

The BigSky Datacenter Development Platform gives chipmakers and hyperscalers a way to run datacenter workloads, port software, and validate RISC-V in a representative server environment. Demonstrations include Canonical Ubuntu 26.04 LTS, Red Hat RHEL 10, NVIDIA CUDA, and AMD ROCm.

Infrastructure

Datacenter systems depend on more than the main CPU. SiFive configurable RISC-V IP can support the silicon around the compute node, including memory and storage, management and control, networking and connectivity, retimers, and security. Teams can tailor these processors to the requirements of each system.
