Spill the wine! Rhea1 taped out by SiPearl!
SiPearl has taped out Rhea1, the company’s 80-core Arm-compatible processor for HPC. The company also has single- and dual-socket Rhea1 reference servers.
SiPearl is an EU-funded company created to foster supercomputing expertise in the region. Among various government and funny-money entities, SiPearl counts a few private investors, including Cathay Venture. That Taiwanese firm joined the company’s recent €130M round.
Based on the Arm Neoverse-V1, the Rhea1 is dated before it even samples. In 2020, SiPearl was the first announced V1 customer. In 2025, it could be the last to tape out a chip. Although SiPearl has sought to balance performance and power efficiency, the newer, faster NeoVerse-V3 would now be a better choice for HPC.
