Investment Summary

My core conclusion is simple: In the AI PC battle, don't bet on camps; bet on toll collectors. Make TSMC your foundation, AMD your offensive play, ARM a small position to follow, Intel just a lottery ticket, wait for Qualcomm's repricing, and don't chase FOMO after NVIDIA's news pulse.

NVIDIA and MediaTek's entry into AI PC appears on the surface as a new chip combination for consumer PCs, but the essence is the Windows on-device AI ecosystem moving from isolated pilot projects to multi-player competition. My assessment is that this war shouldn't be simplified into a religious "x86 vs. Arm" standoff. What's truly worth studying is who can transcend the replacement cycle, sustainably capture gross margins, cash flow, and pricing power within the industry chain.

I view AI PC as a three-tiered opportunity: The first tier is the advanced process toll collector. No matter who wins, TSMC more easily collects the tolls. The second tier is the overflow of computing power and platform, where AMD and NVDA represent the x86 offensive and the extension of the GPU software stack, respectively. The third tier is architectural diffusion and turnaround plays. Both ARM and INTC have elasticity, but position discipline must be stricter.

1. Industry Judgment: AI PC Moves from Concept to Shipment Verification

In 2024, Gartner forecasted 2025 AI PC shipments to reach 114.225 million units, accounting for 43% of the PC market. After an update in 2025, impacted by tariffs and procurement rhythm disruptions, the forecast was revised down to 77.792 million units, representing 31%. However, 2026 shipments are still expected to reach 143.113 million units, with a penetration rate of 54.7%. The insight I gain from this data isn't that "AI PC demand is falsified," but that short-term rhythms fluctuate, but the long-term direction towards standardization remains unchanged.

From an investment perspective, the real challenge of AI PC isn't "having an NPU or not," but whether users are willing to upgrade their devices for a local AI experience. If application layers stagnate at meeting notes, image generation, and simple assistants, the upgrade elasticity will be lower than the market's most optimistic expectations. However, if enterprise users begin adopting private computing, low-latency inference, and local knowledge base deployment as standard configurations, AI PC will transform from a consumer electronics narrative into an enterprise IT upgrade story.

2. Competitive Landscape: Chip Makers Fight, TSMC Collects Tolls

The surface narrative of AI PC is Arm challenging x86, but I'm more concerned about where the profit pool migrates. NVIDIA's strength lies in its GPU and AI software stack, AMD's in its x86 CPU and GPU combination, Qualcomm's in low power and communications, and Intel's in its legacy ecosystem and enterprise channels. Each has advantages, but they also share a commonality: High-end chips cannot bypass advanced process nodes.

TrendForce reports that global wafer foundry revenue in Q2 2025 was approximately $41.7 billion, with TSMC holding a 70.2% share. In Q4 2025, global wafer foundry revenue was about $46.3 billion, with TSMC's share around 70.4%. This means as long as AI PCs, AI servers, mobile APs, and edge AI chips continue to compete for advanced processes, TSMC is not merely a cyclical stock; it's more like the tollgate for the entire AI hardware era.

I don't believe every new product launch warrants a chase, but I do think that every instance of intensifying industry competition should prompt a reverse question: If the winner is still uncertain, who can charge all winners? In the AI PC realm, my answer remains advanced processes, packaging, key IP, and platform software, rather than simply betting on a single architectural slogan.

3. Target Ranking: Base Position on TSM, Offensive on AMD, Elasticity on Intel/ARM

Over the past year, semiconductor stocks have already priced in AI PC, on-device AI, and computing spillover effects. Daily price data from Yahoo Finance shows that within the sample period, AMD, Intel, ARM, and TSM all exhibited strong elasticity, but they represent different risk-return profiles. My approach isn't to buy all AI PC-related targets together, but to layer them based on certainty, valuation discipline, and industry chain position.

My core conclusion is straightforward: This isn't a war to only bet on the winner; it's a war to bet on toll collectors, platforms, and predictable cash flows. If the market prices in a full runup on the day of a news announcement, I'd rather wait. If a pullback brings the risk-reward of good companies back into a reasonable range, my priority is TSM and AMD, followed by the elastic opportunities in ARM and Intel.

4. Risk Disclaimers

The risks of this theme cannot be ignored. First, AI PC applications may fall short of expectations, leading to a weaker-than-anticipated replacement cycle. Second, if Windows on Arm compatibility improvements are too slow, the narratives of Qualcomm and new entrants will be suppressed. Third, tariffs, paused corporate procurement, and macroeconomic uncertainty can dampen PC demand. Fourth, if there is a temporary mismatch in advanced process supply and demand, TSMC could also face valuation pullbacks. Fifth, the entire AI chain is highly valued; if US stock risk appetite declines, the most elastic targets are often the fastest to correct.

Therefore, I prefer to view AI PC as a long-term industrial migration rather than a short-term news trade. The truly professional approach isn't buying slogans on product launch day, but waiting for sentiment to cool before buying into the ecosystem, the toll collectors, and companies that can consistently deliver cash flow.
