Intel Invests €5 Billion in Irish Fab to Boost Xeon Processor Production

Intel has announced a €5 billion ($5.7 billion) investment to expand semiconductor production capacity at its Leixlip campus in Ireland, reinforcing its commitment to advanced manufacturing in Europe. The move comes as the company seeks to ramp up output of its critical Xeon processor line amid growing demand for high-performance computing and AI workloads.

The investment will focus on upgrading Fab 34, where Intel plans to install leading-edge manufacturing equipment to produce its Xeon 6 and next-generation Xeon processors built on the Intel 3 process node. Infrastructure upgrades include expanding the automated track system, an overhead conveyor belt that transports silicon wafers between different fabrication environments, enabling more efficient and scalable production.

“This €5bn investment represents a definitive commitment to maximize capacity at our Leixlip campus and increase what we can deliver to Intel Foundry customers,” said Naga Chandrasekaran, Intel’s executive vice president, chief technology and operations officer, and general manager of Intel Foundry. “By investing in our existing fabs with state-of-the-art technology and installing cutting-edge tools, we are not just increasing output of critical products like Xeon 6 and next-gen Intel Xeon processors built on Intel 3, we are ensuring that Ireland remains at the forefront of the world’s most advanced manufacturing ecosystems, while strengthening the region’s role in the global technology landscape.”

Since beginning operations in Ireland in 1989, Intel has invested more than €30 billion ($34 billion) in the region. The Leixlip campus now employs approximately 4,900 people, though the company offered voluntary redundancy packages to workers there in 2024 as part of a broader $10 billion cost-cutting initiative.

The announcement follows Intel’s repurchase of a 49 percent stake in Fab 34 in April 2026 for $14.2 billion. The chipmaker had originally sold that equity stake to an Apollo Global Management joint venture in 2024 for $11.2 billion. Together, these moves signal Intel’s strategic focus on regaining full control of its most advanced fabrication facilities while scaling production to meet market needs.
