The next global battle for artificial intelligence will not only take place in American laboratories. It will also unfold in Montpellier. By the end of 2026, CINES is set to host the first AMD Helios rack expected in Europe: a giant computing cabinet housing 72 accelerators, designed to train and operate AI models at a scale previously reserved for a few global groups. Behind this technical feat lies a political and economic message: Europe wants direct access to the machines that will determine the digital power of tomorrow.
The announcement comes as AMD seeks to transform its status from a challenger to Nvidia. For years, the AI market has been dominated by its rival’s chips and the CUDA software ecosystem. Helios represents a much broader response than just a new processor: AMD now offers a complete system, from computing to networking, from cooling to software. France will thus be one of the first European grounds where this strategy can be tested by researchers and industry players.
A Machine of 72 GPUs at the Heart of Montpellier
GENCI, the French public body responsible for providing high-performance computing resources, plans to deploy an AMD Helios rack at the National Computing Center for Higher Education, CINES, in Montpellier. The installation is scheduled for the end of 2026 and is expected to be the first of its kind in Europe.
The rack combines 72 AMD Instinct MI455X GPUs, sixth-generation EPYC processors, the Pensando network, and the open software stack ROCm. AMD announces exaflop-class computing capacity for AI applications, with a massive amount of high-bandwidth memory. These performances remain theoretical data and claims from the manufacturer; their actual value will depend on models, software, and the teams’ ability to optimize their workloads.
Why Helios is a Direct Response to Nvidia
The novelty is not just the power of each chip. In modern AI, accelerators must work together as a single machine. Data exchanges, memory, networking, and cooling become as important as the GPU itself. This is why AMD presents Helios as a “rack-scale” architecture: the relevant product is no longer an isolated card, but the entire cabinet.
This approach directly targets Nvidia’s integrated systems. According to published specifications and initial technical analyses, AMD particularly emphasizes memory capacity and the openness of its architecture. However, some comparisons still give Nvidia an advantage in terms of the total power announced per rack. The real competition will therefore be measured less on a spectacular figure than on operating costs, consumption, availability, reliability, and the ease with which developers can move their models.
France is Already Preparing for the Post-Adastra Era
Montpellier was not chosen by chance. CINES already hosts Adastra, a supercomputer used for climate research, astrophysics, materials, energy, chemistry, and health. French teams therefore have concrete experience with AMD accelerators and environments where classical scientific computing and artificial intelligence converge.
The Helios rack is set to serve as a gateway to Alice Recoque, the future European exascale system led by the Jules Verne consortium under the guidance of GENCI and CEA, with Dutch and Greek partners. Its deployment at TGCC is expected in the second half of 2027. By providing early access to the next technological generation, Montpellier aims to enable researchers to prepare their codes ahead of the arrival of this much larger infrastructure.
A Full-Scale Test for European Sovereignty
The term “sovereignty” is often used in discussions about AI, but it becomes concrete when it comes to reserving thousands of GPUs, securing sensitive data, and mastering the software that powers the models. Europe does not yet manufacture all the critical components it needs. However, it can diversify its suppliers, impose open standards, and retain computing capacity accessible to its universities, laboratories, and certain companies on its territory.
Helios will not make Europe independent by itself: AMD remains an American company, and advanced chip manufacturing depends on a global supply chain. But the arrival of a credible alternative prevents a single player from controlling access to infrastructure, software tools, and the pace of upgrades. For public buyers, this competition can also improve commercial conditions and reduce the risk of technological lock-in.
Electricity and Cooling: The Other Battle
A computing cabinet as dense as this cannot be installed like a conventional server. It requires a significant power supply, liquid cooling, and precise data center design. AMD and Schneider Electric have presented a joint reference design to accelerate the deployment of these “AI factories.” The partnership highlights a reality often hidden by chatbot demonstrations: the race for AI is also a race for transformers, pumps, networks, and energy efficiency.
For France, this aspect can become an industrial advantage. Schneider Electric has global expertise in energy management and data centers. However, it also creates a responsibility: a public infrastructure must demonstrate its scientific and economic utility against its energy cost. Success will not be judged by the number of GPUs installed, but by the discoveries, models, and applications actually produced.
What Researchers Will Be Able to Do with It
The uses far exceed conversational assistants. Such a machine can accelerate climate simulation, design new materials, molecular modeling, medical research, or scientific image analysis. It can also help train European models specialized in languages, industry, cybersecurity, and sciences, with data that does not necessarily need to leave the territory.
The challenge will be software. Many teams have built their tools around the Nvidia ecosystem. ROCm is making progress, but adapting libraries, training engineers, and optimizing codes will take time. Early access to the Montpellier rack makes perfect sense here: it should allow for identifying difficulties before the commissioning of future European supercomputers.
The Signal the Global Market Will Watch
Microsoft has already announced that it will be one of the clients of Helios in the second half of 2026, while several manufacturers and cloud operators are preparing their own offerings. If the systems deliver on their promises, AMD could exert new pressure on prices and the closed model that has structured the AI boom. If the software or deliveries disappoint, Nvidia will retain a significant advantage.
This is why the arrival of Helios in Montpellier goes far beyond the technical specifications of a supercomputer. France will test one of the few architectures capable of shifting the global balance of AI infrastructure. The true verdict will come from researchers: their ability to run complex programs, share resources, and transform this power into useful results will determine whether Europe is truly beginning to regain control.
