Huang Rengxun declares the beginning of a new era of PCS! A deep dissection of NVIDIA's ARM ecosystem, a full list of US stocks from upstream to downstream

I. The New PC Era: ARM Architecture Challenges the Traditional X86 Ecosystem (Keywords: AI PC, ARM Architecture, X86, NVIDIA CUDA)

II. Upstream of the Industry Chain: Core Technology and Hardware (Keywords: Chip Architecture, EDA, Advanced Process, Packaging & Testing, Storage, US Stock Upstream Stocks)

1. ARM (Stock Code: ARM) — Core Chip Architecture Licensor

    

   As the holder of the ARM architecture, both NVIDIA and MediaTek rely on ARM's underlying architecture license for chip design. ARM not only charges fixed licensing fees but also receives ongoing royalties for every mass-produced chip. As the penetration rate of ARM architecture PCs continues to rise and the unit price of high-end AI chips increases, ARM's revenue and profits will steadily grow, making it the most stable core target in this sector.
2. EDA Tool Duopoly: Synopsys (SNPS), Cadence (CDNS)

    

   High-end AI PC chips integrate CPU, GPU, and NPU, with extremely high design complexity that must rely on EDA design tools for simulation, verification, and iteration. Both leading companies have incorporated AI-assisted design features to accelerate the rollout of ARM architecture PC chips. Regardless of competition among downstream chip manufacturers, EDA companies continue to collect licensing fees, making them long-term beneficiaries in the chip sector.
3. TSMC (TSM) — Leader in Advanced Process and Packaging

    

   The new generation of ARM AI PC chips depends on 3nm and even 2nm advanced processes for production, and also requires TSMC's unique CoWoS advanced packaging technology to integrate multiple chiplets. Currently, very few companies globally can meet these production requirements. As the manufacturing foundation of global hard tech, TSMC deeply benefits from the capacity expansion of AI PCs and is the core cornerstone of the entire industry chain.
4. ASE Technology (ASX) — High-End Chip Packaging and Testing Leader

    

   After chip production, advanced packaging and testing are indispensable. As AI chip complexity increases, the technical threshold for high-end packaging and testing rises significantly. ASE, as the global leader in packaging and testing, handles the follow-up process for CoWoS packaging. The AI PC upgrade cycle will bring massive orders, providing strong earnings growth certainty.
5. Micron Technology (MU) — Core Memory Stock

    

   Running local large models imposes high demands on memory. Traditional 16GB memory is gradually being upgraded to 32GB, 64GB, or even 128GB, and devices are standardizing on high-speed LPDDR5X memory. AI PCs are driving both volume and price growth for memory chips. As a global memory giant, Micron directly enjoys the benefits of this upgrade cycle, with a hard and clear logic.

III. Midstream of the Industry Chain: Chip and System Competition (Keywords: NVIDIA, Qualcomm, AMD, High-Speed Connectivity Chips, PC Brand Manufacturers, US Stock Midstream Targets)

1. NVIDIA, Qualcomm — Architects of the New ARM PC Order

    

   Leveraging its powerful GPU and AI ecosystem, NVIDIA is bringing data center computing power down to terminal PCs, expanding into the consumer market through the ARM architecture and continuously widening its technological moat.

    

   Meanwhile, the market generally underestimates Qualcomm's value. Its Snapdragon X Elite has already been validated in the ARM AI PC market and is deeply integrated with Microsoft. As the ARM PC pie continues to grow, Qualcomm, as an established player in edge AI computing, also fully enjoys the industry's growth dividends. Combined with valuation advantages, it offers high investment cost-effectiveness.
2. AMD — Guardian of the X86 Ecosystem

    

   AMD is currently the only company with both high-performance X86 CPUs and discrete GPUs. Its Ryzen AI processors integrate specialized AI engines capable of smoothly running local large models. Before the ARM ecosystem becomes fully pervasive, a large number of enterprise applications still rely on the X86 architecture, making AMD a core target spanning both architectures. Any stock price pullback presents a buying opportunity.
3. Astera Labs (ALAB) — Invisible Champion in High-Speed Connectivity Chips

    

   Under the multi-chip integration architecture, high-speed data transmission between CPU, GPU, and memory becomes critical. Astera Labs specializes in high-end intelligent connectivity chips that solve data transmission loss issues in high-computing-power devices. Originally focused on the data center field, as PC hardware moves toward server-level performance, this technology is rapidly being ported down, providing strong earnings flexibility for the company.
4. Dell, HP — Global PC Brand Leaders

    

   Upstream chips and components eventually materialize in terminal systems. Dell and HP, as long-established global PC manufacturers, directly benefit from the AI PC super upgrade cycle. The commercial market is the first to initiate upgrades, with enterprise demand for AI office tools driving both PC shipments and average selling prices higher. Both companies have stable business models and attractive valuations.

IV. Downstream of the Industry Chain: Software Application Ecosystem — The Ultimate Gold Mine (Keywords: Operating System, Office Software, Cybersecurity, AI Applications, US Stock Downstream Targets)

1. Microsoft — Core of the Operating System Ecosystem

    

   After NVIDIA and Qualcomm complete the hardware link, Microsoft's Windows Copilot+ PC becomes the key to deployment. Microsoft not only collects system licensing fees but also drives growth in Office 365 subscriptions and Azure cloud services. Through hardware-software synergy, AI PCs become a market necessity, serving as the "anchor" of the entire ecosystem.
2. Adobe (ADBE) — Creative Software Leader

    

   Previously, creative tasks like image and video editing were highly dependent on cloud services due to limited local computing power. Now, with AI PCs, generative AI models like Firefly can run locally, eliminating network latency and privacy concerns, significantly enhancing the creative experience. This continuously stimulates user paid subscriptions, directly benefiting from AI PC adoption.
3. CrowdStrike (CRWD) — Endpoint Cybersecurity Leader

    

   Every AI PC carries a local large model, storing large amounts of enterprise core data on the endpoint, which simultaneously escalates cybersecurity risks. Traditional antivirus software cannot meet the protection needs of the AI era. AI-based behavioral recognition endpoint security has become an industry standard. As AI offense and defense enter a new phase, enterprise security budgets continue to grow, and CrowdStrike, as the industry leader, enjoys long-term incremental benefits.

V. Lazy Configuration: Three Levels of ETFs — One-Click Layout for the Entire Sector (Keywords: Semiconductor ETF, Technology ETF, Software ETF, US Stock ETF)

1. VanEck Semiconductor ETF (SMH) — Pure Hardware Track

    

   Focuses on AI semiconductor hardware. The top ten holdings include core upstream and midstream companies like NVIDIA, TSMC, Qualcomm, AMD, and Micron, fully covering the AI PC hardware industry chain. For those bullish on the chip sector, this is suitable for long-term regular investment.
2. iShares U.S. Technology ETF (IYW) — Balanced Hardware and Software Allocation

    

   Holdings include both software companies like Microsoft and Adobe, and hardware giants like NVIDIA and AMD, covering the entire technology industry chain. Its performance is stable, making it suitable for investors seeking balanced returns.
3. iShares Expanded Tech-Software Sector ETF (IGV) — Focus on Downstream Applications

    

   If you believe the hardware segment is overvalued, you can allocate to the downstream software ecosystem. This ETF heavily weights application leaders like Microsoft, Adobe, and CrowdStrike. The wider the AI PC hardware penetration, the greater the profit potential on the software side.
