SiPearl

Positioning

SiPearl is a French private fabless semiconductor designer developing Arm-based CPUs for sovereign HPC, AI inference, and data-center infrastructure. Its Rhea1 processor taped out in June 2025, powered on May-13-26, and is committed to the EuroHPC JUPITER exascale system; the company also has Rhea2 selected for France's Alice Recoque system and is partnering with Semidynamics on a European rack-scale inference platform. The key distinction is strategic European sovereignty and strong institutional anchoring, while commercial volume deployment and third-party performance validation remain open questions.
