Intel Shifts Fab Capacity From Client to Server CPUs as AI Demand Outruns Supply

By Grace Kim, Chip Dispatch

Intel generated $7.3 billion in Data Center and AI revenue in the third quarter of 2026, up 17% sequentially and nearly 80% year over year, and it is now moving manufacturing capacity out of its shrinking client PC business to feed that growth. The company is converting Oregon lines originally set for Intel 18A client processors to Intel 3 server production, expanding Fab 24 in Ireland, accelerating tool installation at Fab 62 in Arizona, and adding advanced packaging capacity in New Mexico and Malaysia.

CEO Lip-Bu Tan framed the pressure plainly on the earnings call. "The industry continues to navigate one of the most significant supply shortages in history, driven by the unprecedented demand for Super Intelligence," Tan said. "Against this backdrop, I am pleased by the progress we made growing our server supply in Q3. I am mindful about the ongoing challenges we face in the future quarters to keep pace with server demand."

Which fabs are being redirected?

Intel's immediate priority is raising output of Xeon 6 'Granite Rapids' processors, built on the Intel 3 node. The company has begun expanding capacity at Fab 24 near Leixlip, Ireland, though that volume will not come online until the end of 2027 unless the schedule can be pulled forward.

The faster lever is Oregon. CFO Dave Zinsner said Intel will take Intel 18A wafer capacity offline there and retool it for Intel 3, freeing output for data center products instead of the Panther Lake client processors those lines were built to make.

"What we are taking offline to put Intel 3 into Oregon is 18A wafers, which we are generally going to build Panther Lake products," Zinsner said. "We see the opportunity with some of that capacity freed up to go produce more data center wafers."

The additional Oregon Intel 3 capacity should enter production in the second half of 2027. Weaker PC demand made the trade possible; the consumer market is contracting and will keep contracting over coming quarters, according to the company.

Granite Rapids is already Intel's fastest-ramping server processor family, yet demand still exceeds supply. Intel is also lifting yields and cutting cycle times. The company said Intel 3 manufacturing costs have fallen roughly 15% since the first quarter of 2026.

What about Arizona and future nodes?

In Arizona, Intel is ramping Intel 18A at Fab 52 and has accelerated equipment installation at the adjacent Fab 62, which will become its second high-volume site for 18A, 18A-P, and derivative processes. The company has not disclosed how Fab 62 capacity will split between client and data center products.

On the client side, Intel expects to gain share with Core Ultra 400-series 'Nova Lake' CPUs, which will require high-volume production. Intel says data center CPU demand will stay strong through 2027 and 2028 as AI infrastructure operators deploy more CPU-intensive agentic and inference workloads.

Why are wafers not the whole problem?

Intel is also short of advanced organic substrates for its multi-chiplet packages. It has worked with substrate suppliers and expects roughly 40% more substrate capacity in the second half of 2027.

"We are not only constrained on the wafer side, we are also constrained on the substrate side," Zinsner said. "So, it is important we get the substrate piece of this ramped up to be able to meet the demand."

The packaging buildout matters beyond Intel's own chips. Granite Rapids uses EMIB to connect compute dies. Clearwater Forest Xeons combine EMIB with Foveros Direct 3D and hybrid bonding to stack Intel 18A compute dies on Intel 3 base dies. Intel is expanding EMIB, EMIB-T, Foveros 3D and hybrid bonding capacity in New Mexico and Malaysia for internal products and external customers.

"On Advanced Packaging, we are pleased by the progress we are making with EMIB and EMIB-T for our internal products," Tan said. "Both continue to see significant external customer traction as well."

Tan added that Hybrid Bonding Interconnect readiness shows robust progress, calling it an enabler of 3D chip stacking for upcoming server products.

How much capital is required?

Intel expects capital expenditure of approximately $20 billion in 2026, rising significantly in 2027 without a firm figure disclosed. Firm purchase orders to equipment suppliers grew nearly 40% sequentially in Q3. The company is also evaluating ways to accelerate its Ohio manufacturing complex, where the first major structural truss was recently installed.

"We have made good progress securing the equipment required to support our growth plans with firm purchase orders to equipment suppliers increasing nearly 40% sequentially," Zinsner said. "We are also accelerating clean room build-outs, including Fab 62 in Arizona and exploring opportunities to accelerate in Ohio."

Expansion takes time. Tools must be installed and qualified, wafers must pass through long manufacturing cycles, and substrate makers must add their own output. Intel therefore expects supply constraints to remain particularly severe through the first half of 2027, even as the client PC market keeps contracting. The company expects added capacity, higher yields and better substrate availability to let it capitalize on AI infrastructure demand in the second half of 2027 and beyond.
