Investment Summary

My core conclusion is just one sentence: In the AI PC war, don't bet on camps; bet on toll booths. TSMC is the foundation, AMD is the offensive play, ARM is a small position to follow, Intel is just a lottery ticket, Qualcomm awaits repricing, and NVIDIA should not chase the FOMO after news pulses.

NVIDIA and MediaTek's entry into AI PCs, on the surface, adds a new chip combination to consumer PCs, but fundamentally, it represents the Windows on-device AI ecosystem moving from single-point pilots to multi-player competition. My assessment is that this war should not be simplified into a religious "x86 vs. Arm" standoff; what's truly worth studying is who can navigate the upgrade cycles and sustainably secure gross margins, cash flow, and pricing power within the industry chain.

I view AI PC as a three-tier opportunity: The first tier is the advanced process toll booth. Regardless of who wins, TSMC more easily collects the toll. The second tier is the spillover of computing power and platforms, 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 upside potential, but position discipline must be stricter.

I. Industry Outlook: AI PC Moves from Concept to Shipment Verification Phase

Gartner estimated in 2024 that AI PC shipments would reach 114.225 million units in 2025, accounting for 43% of the PC market. After a 2025 revision, influenced by tariffs and procurement pace disruptions, the forecast was lowered to 77.792 million units, representing 31%, but 2026 is still projected to reach 143.113 million units, with a penetration rate of 54.7%. My takeaway from this data is not that "AI PC demand is falsified," but that short-term rhythms will fluctuate, but the long-term direction of 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 the local AI experience. If the application layer only stays at meeting summaries, image generation, and simple assistants, the upgrade elasticity will be lower than the market's most optimistic expectations. However, if enterprises start adopting privacy 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 narrative.

II. Competitive Landscape: Chipmakers Fight, TSMC Collects Toll Fees

The surface-level narrative of AI PC is Arm challenging x86, but I'm more concerned about where the profit pool is shifting. NVIDIA's strength lies in its GPU and AI software stack; AMD's strength is in its x86 CPU and GPU combination; Qualcomm's strength is in low power consumption and communication; Intel's strength is in its legacy ecosystem and enterprise channels. Each has its advantages, but the commonality is also clear: High-end chips cannot escape advanced manufacturing processes.

TrendForce disclosed that global wafer foundry revenue was approximately $41.7 billion in Q2 2025, with TSMC holding a 70.2% market share. In Q4 2025, global wafer foundry revenue was approximately $46.3 billion, with TSMC's share around 70.4%. This means that as long as AI PCs, AI servers, mobile APs, and edge AI chips continue to compete for advanced process nodes, TSMC is not simply a cyclical stock but more like a toll gate for the entire AI hardware era.

I don't believe every new product launch is worth chasing for gains. However, I believe that every time industry competition intensifies, one should ask the reverse question: If the winner is still uncertain, who can charge all winners? In the AI PC sector, my answer remains advanced manufacturing processes, packaging, key IP, and platform software, rather than simply betting on a single architectural slogan.

III. Asset Ranking: Core Holdings in TSM, Offensive Play in AMD, Upside in Intel/ARM

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

My core conclusion is simple: This is not a war where you only buy the winner; it's a war where you should buy toll booths, platforms, and companies with certain cash flow. If the market gets overly excited on the day of a news release, I'd rather wait. If a pullback brings the risk-reward profile of good companies back into a reasonable range, I will prioritize TSM and AMD, followed by the elastic opportunities in ARM and Intel.

IV. Risk Factors

The risks of this theme cannot be ignored. First, AI PC applications may underperform expectations, leading to a weaker-than-expected upgrade cycle. Second, if Windows on Arm compatibility improvements are too slow, the narratives for Qualcomm and new entrants will be suppressed. Third, tariffs, corporate procurement pauses, and macroeconomic uncertainties can affect PC demand. Fourth, if there is a temporary mismatch in advanced process supply and demand, TSMC could also experience valuation pullbacks. Fifth, the valuation of the entire AI chain is high; once US stock risk appetite declines, the most elastic assets often experience the fastest pullbacks.

Therefore, I prefer to view AI PC as a long-term industrial migration, rather than a short-term news trade. A truly professional approach isn't to buy slogans on launch day, but to wait for the emotional tide to recede and then buy ecosystems, toll booths, and companies that can consistently deliver cash flow.
