How do you build Europe's first sovereign high-performance processor from scratch? What does it take to challenge Intel and AMD with just 200 engineers and €150 million?

In this comprehensive episode of Opening Voices, I sit down with Philippe Notton (CEO) and Craig Prunty (VP) from SiPearl to explore Europe's most ambitious semiconductor project:

🔹 How 200 engineers across 5 R&D sites design a 60 billion gate processor

🔹 Why ARM is becoming the new battlefield for server processors

🔹 The €20 million data center built to emulate Europe's most complex chip

🔹 How hyperscalers like Amazon and Google are driving the custom silicon revolution

🔹 Why AI inference on CPUs can be 70x more energy efficient than GPUs

🔹 The chiplet revolution and Europe's opportunity in post-Moore's Law era

We dive deep into the technical challenges, market dynamics, and geopolitical implications of building sovereign computing infrastructure in Europe.

Why are CPUs making a comeback in the age of AI? And how can Europe build a sovereign compute infrastructure in a world dominated by American and Asian tech giants?

In this final episode of Opening Voices with the SiPearl team, I sit down with Philippe Notton (CEO) and Craig Prunty (VP) to explore the future of processor design and its impact on AI, sovereignty, and Europe’s industrial strength.

We discuss:

🔹 Why CPUs can outperform GPUs in inference workloads

🔹 How SiPearl’s chip design drastically reduces energy consumption

🔹 The growing importance of chiplet architectures for modular compute

🔹 Why Europe needs its own electronic design cloud infrastructure

🔹 How to reclaim industrial skills and build a sovereign value chain

🔹 The difference between SiPearl and ASML in the semiconductor ecosystem

🔹 Why sovereignty isn't about isolation—but about control and resilience

Why are tech giants like Apple, Amazon, and Google building their own processors—and what does it mean for Europe?

In this new episode of Opening Voices, I sit down with Craig Prunty, VP at SiPearl, to explore how processor design is becoming a strategic lever for performance, sovereignty, and efficiency.

We discuss:

🔹 Why ARM is taking over the server market

🔹 The real reasons hyperscalers are going boutique in chip design

🔹 What makes European players like SiPearl competitive—despite limited funding

🔹 The opportunities for Europe to scale its processor ambitions with partners like TSMC

Join the conversation—can Europe reclaim control over its compute infrastructure?
