European high-performance energy-efficient processors for HPC, AI and Data Centres

Our vision

Philippe Notton, CEO et fondateur de SiPearl, le concepteur du microprocesseur haute performance et basse consommation

Because major challenges for Europe in defense, security, health, energy and climate require processing huge volumes of strategic data in a fraction of a second, SiPearl is building European high-performance energy-efficient backdoor-free & kill switch-free processors dedicated to supercomputing and AI.

In a complex geopolitical context, we are contributing to Europe’s technological sovereignty in scientific, societal and environmental fields with a reduced carbon footprint.

Philippe Notton
CEO & Founder

Currently manufactured by TSMC in Taiwan, Rhea1, our first family of processors, will be available for sampling in early 2026. It will equip JUPITER, the first European exascale supercomputer which is owned by EuroHPC JU and operated by Jülich Supercomputing Centre.
