SiPearl: Rhea1 key features to accelerate HPC & AI inference

Attending ISC tradeshow in Hamburg (booth L22), SiPearl, the company building the high-performance low-power European microprocessor for HPC and AI inference announces the main features of Rhea1, its firstgeneration microprocessor.

Designed with high-performance energy-efficient arm® Neoverse V1 platform, Rhea1 will include in a single package:

80 arm® Neoverse V1 cores ensuring high compute performance and efficient
performance per watt. Each core includes 2 Scalable Vector Extension (SVE) of 256 bits
each, enabling fast vector computations while optimizing area and energy use;

Rhea1 is perfectly suited to traditional HPC workloads – its initial target market – and also to AI inference workloads. Thanks to both the generous memory capacity and high bandwidth of in-package HBM, it will deliver extraordinary performance and energy-efficiency with an unrivalled byte-per-flop ratio.

First samples in 2025.

“Combining the performance and energy-efficiency of arm® Neoverse V1 cores with inpackage HBM and embedding SiPearl patented memory and power management schemes, Rhea1 will fulfill the mission entrusted by EuroHPC JU and the European Processor Initiative consortium: to bring dedicated high-performance microprocessor technologies back to Europe. Rhea1 will be a world class microprocessor for HPC and AI inference. In the fastgrowing generative AI market, it will be a great alternative to existing solutions for AI inference workloads at lower cost while offering higher flexibility to model changes”, concluded Philippe Notton, CEO and founder of SiPearl.
