AMD Instinct MI430X and 6th Gen EPYC to Power €387.8M LUMI-AI Supercomputer

The European High-Performance Computing Joint Undertaking (EuroHPC JU) signed a procurement contract on August 31, 2026, with systems vendor Bull to deliver LUMI-AI, a next-generation supercomputer built on AMD Instinct MI430X GPUs and 6th Gen AMD EPYC 256-core processors. The contract, valued at 387.8 million euros including acquisition, delivery, installation and maintenance, will be funded equally by EuroHPC JU and the six-country LUMI AI Factory consortium, AMD said. Deployment is scheduled for the second half of 2027.

System Hardware and Architecture

LUMI-AI will be installed at a new data center operated by CSC – IT Center for Science Ltd. in the Renforsin Ranta business park in Kajaani, Finland. The liquid-cooled system is based on Bull’s BullSequana XH3500 architecture, designed for advanced AI workloads. Additional technology partners include IBM, which will provide a storage solution based on IBM Storage Scale, and Nokia, which will contribute data center networking expertise alongside Bull’s BXI high-performance interconnect, CSC stated.

The system will use Bull’s patented Direct Liquid Cooling technology, which uses warm water to cool the hardware, Bull said. The partners expect LUMI-AI to provide 10 times the AI capacity and nearly twice the high-performance computing capability of the current LUMI supercomputer.

CSC attributed the projected capability gap between AI and traditional computing performance to architectural differences. According to CSC, new GPU architectures deliver substantially higher performance in AI-driven tasks, while traditional computing performance measures highly precise floating-point calculations used in scientific simulations; as a result, advances in processor architectures increase AI capacity manyfold relative to traditional computing performance.

A multi-tenant architecture, additional compute and storage resources, and extensive API-based access are intended to support diverse AI communities and modern development environments, according to AMD. The system will also integrate with LUMI-IQ, a quantum computing platform to be delivered by IQM Quantum Computers (IQMX ) and co-located in the same Kajaani data center, forming a hybrid platform combining high-performance computing, AI and quantum workloads, according to CSC.

Contract Terms, Funding and Procurement

The EuroHPC JU release states that Bull was selected following a call for tender launched in May 2025, while Finland was selected as the hosting site in December 2024. The system will be owned by EuroHPC JU and hosted by the LUMI AI Factory consortium of Finland, Czechia, Denmark, Estonia, Norway and Poland.

EuroHPC JU will fund 50% of the total cost from the Digital Europe Programme, with the remaining 50% funded by the consortium, according to the EuroHPC JU. Supercomputing resources will be allocated jointly by EuroHPC JU and the consortium in line with their respective investments. The system is designed primarily to serve startups and small and medium-sized enterprises for research and innovation, while remaining accessible to the wider research community.

“With LUMI-AI, EuroHPC JU has now signed its sixth AI Factory procurement contract for a next-generation AI-optimised supercomputer,” said Anders Jensen, EuroHPC JU Executive Director.

Sustainability Design

LUMI-AI will be powered entirely by renewable energy, according to AMD. Excess heat captured by the liquid-cooling system will be fed into Kajaani’s district heating network, a design CSC said will significantly increase the share of district heating generated using excess heat from its data centers. The partners state the design goal is to make LUMI-AI among the world’s most energy-efficient supercomputers.

LUMI AI Factory Context

LUMI-AI will serve as the computing backbone of the LUMI AI Factory, which has provided AI computing resources and services to European SMEs and startups since April 2025 using the current LUMI supercomputer, according to the EuroHPC JU. Strategic sectors served include manufacturing, health and life sciences, and communication technologies and networks, alongside climate research, materials science and language technology.

“LUMI-AI marks an important next step in the AMD partnership with EuroHPC JU, the LUMI AI Factory consortium and Bull,” said Thomas Zacharia, senior vice president of Global Public Sector and Strategic Partnerships at AMD.

EuroHPC JU, a legal and funding entity combining the European Union and participating countries, has procured 12 supercomputers across Europe, including JUPITER and Alice Recoque, its first exascale systems. The joint undertaking is overseeing the implementation of 19 AI Factories offering free support to SMEs and startups, complemented by 13 AI Factory Antennas selected in October 2025. At the end of July 2026, EuroHPC JU launched a call for tenders to select consortia to build and operate AI Gigafactories in the European Union.
