Intel said during its Q1 2026 earnings call that the ratio of CPUs to GPUs deployed in data centers could tighten by as much as 1:1 in agentic scenarios as AI workloads shift from training to inference. Currently, one CPU is needed for every four to eight GPUs in an AI server, but with Agentic AI, that shifts dramatically to one CPU per GPU. That shift has driven server CPU prices up by as much as 20% since March, with Intel already having confirmed back in October that it’s prioritizing data center chip production over consumer CPUs to meet demand it can’t currently fulfill.

One of the standout details from the call was how CFO David Zinsner described server deployments as shifting, with the ratios of CPUs to GPUs in data centers having already moved from 1:8 to 1:4. He added that as workloads continue migrating towards inference and agentic AI, that ratio could converge to 1:1 or even tilt further in favor of CPUs. “As you think about the growth rate now going forward, it’s [CPU demand] going to become a significant part of the AI [total addressable market],” Zinsner said.

At 1:8, a rack filled with eight GPUs needed a single server CPU to manage orchestration and data handling. But at 1:4, that same rack needs twice as many CPUs, and eight times as many at 1:1. Intel is already supply-constrained on Xeon, with Zinsner stating during the call that the unmet demand “starts with a B. So it’s meaningful.” Server CPU lead times are currently around the six-month mark, with both AMD and Intel acknowledging the demand spike at last month’s Morgan Stanley conference, where Zinsner called the CPU “cool again.”

This supply crunch is translating directly into price increases, with the Commercial Times reporting earlier this week that server CPU prices have risen 10% to 20% since March, with consumer CPUs up 5% to 10% over the same period. Intel raised PC CPU prices in March and adjusted server CPU pricing again at the beginning of April. Analysts expect another round of increases of 8% to 10% in the second half of 2026.

On the call, Zinsner confirmed that higher average selling prices contributed to Intel's Q1 results. "As core count increases, we get the lift on the ASPs from that, and that obviously is meaningful," he said. Intel posted Q1 revenue of $13.6 billion, beating its own guidance midpoint by $1.4 billion, with its Data Center and AI group up 22% year over year to $5.1 billion.

To keep server customers supplied, Intel has been shifting wafer capacity away from client CPUs. The company has been prioritizing data center output since at least October, when Zinsner first acknowledged that capacity constraints on Intel 10 and Intel 7 were limiting the company's ability to serve both markets simultaneously.

Intel says it expects full-year PC unit volumes to decline by low double-digit percentages, and that client revenue should flatten from Q2 onward. Q1 revenues were also partly aided by sales of previously reserved inventory, including older chips that were shipped to meet demand despite their age, adding that supply will increase every quarter going forward, but that the same inventory benefit is unlikely to repeat in Q2.
