Breakthrough chip architecture solves the memory wall bottleneck, delivering unmatched performance, efficiency and scalability for large-scale AI inference — and establishing Europe as a strategic player in next-generation AI hardware.
Paris, France – October 22nd, 2025 — VSORA, a French semiconductor company pioneering next-generation AI processors, announces the successful tape-out of Jotunn8, its signature inference chip designed to power the deployment of artificial intelligence inference in data centers at scale. This milestone marks a critical step that derisks the entire development process by validating the chip’s architecture and enabling industrial production. It confirms VSORA’s ability to move from concept to manufacturing and positions the company among the top three global suppliers of AI inference chips — and the only European player at this level.
Jotunn8’s tape out, less than six months after raising €40M, propels VSORA into an exclusive group of global providers, capable of powering ultra-high performance AI data center inference
This milestone marks the end of the design phase and the beginning of fabrication with top-tier global semiconductor partners. VSORA is now preparing for full-scale deployment, with development boards, reference designs, and servers expected in early 2026.
Tackling AI’s biggest bottleneck: the “memory wall”
Traditional processors — even those from today’s market leaders — are limited by the “memory wall,” where compute units stall while waiting for data, resulting in wasted performance and excessive power draw. At the heart of Jotunn8 is VSORA’s revolutionary architecture, built from the ground up to address this computing’s most persistent bottleneck. By rethinking how compute units interact with memory, Jotunn8 eliminates the traditional trade-offs between speed, efficiency, and scalability.
“The industry has been hitting a wall — literally. The memory wall problem has limited the efficiency of AI hardware for years. With Jotunn8, we’ve broken through that barrier. With our solution, cost per query is significantly reduced, making AI inference business models financially viable at scale.”, says Khaled Maalej, founder and CEO of VSORA
Designed for the Future of AI Inference
As announcements of computing center investments and partnerships multiply, the challenge is no longer just training models — it’s deploying them efficiently across millions of applications, from data centers to edge devices. Jotunn8 is purpose-built for this reality.
Key benefits include:
• Breakthrough performance: 3,200 Tflops of compute power with 288 GB HBM3e memory
• Energy efficiency: Uses 50% less power than current market-leading chips
• Effective design: Chiplet-based solution reduces silicon area for cost effective systems
• Deployment flexibility: Scales seamlessly into wide-ranging AI infrastructure
Powered by TSMC’s 5nm process and cutting-edge CoWoS multi-chip packaging technology, VSORA takes Jotunn8’s performance and scalability to new heights. This achievement was made possible through close collaboration with GUC, VSORA’s silicon implementation partner.
“GUC is proud to help bring VSORA’s advanced AI processor to market”, said Alex Huang, General Manager of GUC Europe. “By combining VSORA’s breakthrough AI inference architecture with GUC’s silicon-proven IP and expertise in advanced nodes, packaging, and physical design, we delivered the Jotunn8 with outstanding performance and efficiency — right on schedule. This achievement showcases the strength of our collaboration and proven design excellence.”
A strategic turning point for VSORA and Europe’s innovation in AI
The tape-out represents a critical engineering achievement for Jotunn8, confirming its architectural integrity and marking the transition into manufacturing. VSORA is now advancing from design to full-scale commercial deployment.
“We set out to design an architecture that could sustain AI’s exponential growth”, added Khaled Maalej. “Jotunn8 represents a new class of processors that make large-scale AI deployment truly viable — technically, financially, and sustainably. This achievement also shows that Europe is not just a consumer of AI hardware, but a genuine innovator shaping its future.”
