Overview

  • SiFive announced adoption of Nvidia’s NVLink Fusion in its high‑performance compute platforms to enable direct, coherent connections to Nvidia GPUs and other accelerators.
  • Reuters reports SiFive is the first RISC‑V chip‑design provider to integrate NVLink, signaling a step toward broader interoperability in AI infrastructure.
  • SiFive CEO Patrick Little said designs using the technology are not expected to reach the market until 2027 or later.
  • Nvidia and SiFive did not disclose financial terms, and both companies presented the collaboration as a multi‑generational roadmap alignment.
  • Nvidia CEO Jensen Huang said bringing NVLink to the RISC‑V ecosystem will let customers combine customizable RISC‑V CPUs with Nvidia accelerators for scalable, power‑efficient systems.
