The CPU market—especially for servers—is about to grow nearly fivefold in the next five years. UBS says ARM will benefit most, AMD next, with Intel trailing. For investors, this shift means huge new opportunities in AI-related stocks beyond GPU champions.

What UBS Says

UBS Global Research released a deep-dive report on the US semiconductor sector. Their top analyst, Timothy Arcuri, argues that the market is underestimating how AI agents will dramatically boost server CPU demand. They forecast the server CPU total addressable market (TAM) will jump from about $30B in 2025 to $170B by 2030—a fivefold increase.

Why CPUs Will Surge

• AI Agents Shift Workloads:

Traditional AI workloads mainly run on GPUs (about 70–80% compute). But as agent-like AI takes over, CPUs do most of the heavy lifting (reversing to 70–80% CPU).

• Huge Increase in Cores Per GPU:

Previous workloads paired each GPU with 8–24 CPU cores. Agent AI setups require 80–120 cores per GPU—up to 10x more.

• Parallel Task Pressure:

Complex agent tasks may spawn dozens of sub-agents, each needing CPU power.

This fundamental shift opens massive new incremental space for CPUs.

Market Size Estimates

UBS Forecasts: Server CPU TAM (Total Addressable Market), 2025–2030

UBS uses both bottom-up (cloud deployment, ASP, units, core ratios) and top-down (overall AI market) models. CPUs will be needed for traditional servers, head-node orchestration, and agent AI racks (standalone).

Who Benefits Most? UBS Ranking

Arm Holdings(ARM.US):

ARM’s server CPU market share is expected to rise from 15% in 2025 to 40-45% by 2030, with revenue share reaching 50-55% due to higher AI CPU prices. ARM’s strengths are better power and memory efficiency, and broad adoption by top cloud providers. However, it still faces challenges with multicore performance and software support. Analysts raised ARM’s 12-month price target to $245 and kept a “Buy” rating.

Advanced Micro Devices, Inc.(AMD.US):

Best suited for high-core, multi-thread workloads. Projected server CPU market share >50%. The current analyst forecast for AMD’s 2030 EPS is $25.27. If the market develops as expected, the revised 2030 EPS could reach $28.14, representing an upside of about 11%.

Intel Corporation(INTC.US) :

Holds x86 lead in traditional servers but is losing ground in AI head nodes. Intel’s upgrade cycle for PCs may benefit from agent AI, but its server CPU gains lag. The bank’s revised upside potential for Intel’s 2030 EPS is about +7%, the lowest among the three companies.

Target Prices (UBS 12-month outlook):

Important Differentiators

• Not all CPUs are equal: Large cloud buyers balance high-core/low-frequency CPUs (good for throughput) versus low-core/high-frequency CPUs (better latency for orchestration).
• Vendors with broad product ranges (varied core counts/frequencies) will outperform single-sku players.
• Utility is measured by transactions per watt, not peak performance.

Cloud vs. Edge: The Wild Card

Agent AI is moving some workloads from cloud to local devices (PCs, phones), which could reduce data center CPU demand by 25%. PC CPU demand could surge instead, benefiting both AMD and Intel.

Investor Takeaway:

Watch for ARM and AMD as top picks for explosive CPU growth driven by AI agent adoption. Intel may still gain, but mostly from PC upgrades. If you’re investing in US tech, allocation beyond Nvidia (the GPU star) is increasingly vital—look for AI CPU winners!
