Socionext today announced a collaboration with Arm and TSMC for the development of an innovative power-optimized 32-core CPU chiplet in TSMCʼs 2 nm silicon technology, delivering scalable performance for hyperscale data center server, 5/6G infrastructure, DPU and edge-of- network markets.

The engineering samples are targeted to be available in 1H2025. This advanced CPU chiplet proof-of-concept using Arm Neoverse CSS technology is designed for single or multiple instantiations within a single package, along with IO and application-specific custom chiplets to optimize performance for a variety of end applications.Leveraging CPU chiplets, and customized application-specific chiplets, multiple target applications can be supported. When new chiplets become available, a cost-effective package level upgrade path can be supported.

"Socionext is a leading provider of custom SoCs for global hyperscale data center, automotive and networking customers. Driven by commercial and time-to-market benefits, there is a growing customer demand for granular compute power. Leveraging silicon re-use to create multiple product platforms enables innovative system architectures. With leading silicon node enablement and our partnership with Arm, we are designing and delivering highly integrated large scale silicon solutions to global customers," said Hisato Yoshida, Corporate Executive Vice President and the Head of Global Development Group at Socionext. "This chiplet complements our customersʼ current SoC designs and provides system architects new degrees of freedom to deliver many platform variants for a product family."

"Arm Neoverse CSS is unlocking greater accessibility to custom silicon and driving innovation across the chiplet ecosystem," said Mohamed Awad, senior vice president and general manager, Infrastructure Line of Business, Arm. "The advanced chiplet proof-of-concept from Socionext is demonstrating what is possible through Arm Total Design and will accelerate the path to custom, workload-optimized solutions for our broader ecosystem."

"TSMC is pleased to support Socionext and Armʼs flexible chiplet design with the outstanding performance, form factor and energy efficiency offered by our 2 nm technology, as well as our comprehensive ecosystem to accelerate time-to-market of customer product innovations," said Dr. Cliff Hou, Senior Vice President of Corporate Research/Research and Development at TSMC. "We have worked with Socionext across many generations of our leading-edge technology, and look forward to extending this collaboration into the 2nm generation."
