TSMC is a pure-play foundry: it makes chips designed by customers and does not sell semiconductor products under its own name. Intel is an integrated device manufacturer (IDM) that designs and sells its own chips while also building a foundry business for outside customers. The key practical difference is that TSMC’s business is organized around external customers, while Intel’s manufacturing capacity still primarily serves Intel products.
What “pure-play foundry” and “IDM” mean
A foundry manufactures chips from designs created by other companies. A pure-play foundry focuses on that customer-manufacturing role rather than competing with customers by selling its own branded semiconductor products. TSMC describes its business this way and says that not selling products under its own name helps it avoid competing with its customers. TSMC 2025 Annual Report

An IDM, or integrated device manufacturer, combines chip design and product sales with manufacturing. Intel designs and sells processors and other semiconductor products through Intel Products, while Intel Foundry manufactures for those internal product groups and offers manufacturing-related services to external customers. Intel products may also be manufactured by third-party suppliers. Intel 2025 Form 10-K

| Question | TSMC | Intel |
|---|---|---|
| Who is the manufacturing business built to serve? | External customers designing their own semiconductor products; TSMC reported 534 customers in 2025. | Intel’s own product groups remain the primary users of its manufacturing capacity; Intel also seeks external foundry customers. |
| Does the company sell its own chips? | It says it does not design, manufacture, or market semiconductor products under its own name. | Yes. Intel designs and sells its own semiconductor products as well as offering foundry services. |
| How established is the external foundry business? | TSMC reported 12,682 different products manufactured and 305 process technologies deployed in 2025. | Intel said in its 2025 Form 10-K that it had few external customers to date; the filing does not give an equivalent customer or product count. |
| What manufacturing services are identified? | Wafer manufacturing across process technologies, alongside investment in advanced technologies and packaging. | Wafer fabrication, advanced packaging, chiplet integration, and design enablement; some packaging services can be used with wafers made at other foundries. |
The figures in the TSMC column are company-reported 2025 measures, not a like-for-like comparison with Intel: Intel’s filing does not report matching customer, product, or process-technology counts. TSMC 2025 Annual Report Intel 2025 Form 10-K
Why customer relationships are different
TSMC’s customer-facing model
TSMC’s operating model is designed to serve companies that bring their own chip designs. It reported 534 customers and 12,682 products manufactured in 2025, across markets including high-performance computing, smartphones, IoT, automotive, and digital consumer electronics. Those company-reported totals indicate a broad customer operation, but they do not establish how TSMC compares with Intel on customer experience, yield, pricing, or market share.
TSMC’s stated position is that the pure-play structure reduces the risk of competing with customers in semiconductor products. That is a corporate description of its business model, not a guarantee that every customer’s commercial interests or supply needs are identical. TSMC 2025 Annual Report

Intel’s internal demand and external ambitions
Intel Foundry has two roles: manufacturing for Intel’s own product groups and seeking business from outside companies. Intel’s 2025 Form 10-K says nearly all Intel Foundry capacity was dedicated to its Client Computing Group and Data Center and AI products, and that the company had few external customers to date. Intel calls an external foundry business a key long-term strategy, but the filing makes clear that strategy is not yet equivalent to TSMC’s established customer-facing model. Intel 2025 Form 10-K
Because Intel competes in products as well as manufacturing, an outside customer may weigh potential commercial conflicts differently than it would with a pure-play foundry. Intel has described steps intended to provide services and separate data and intellectual property; the practical assessment should rest on current contractual protections and execution, not just the company’s stated organizational intent. In 2023, Intel announced a manufacturing-group profit-and-loss structure and internal market-based pricing as part of its internal foundry model. Those were announced organizational goals; Intel’s 2025 filing is the more current source for the state of its external business. Intel Provides Update on Internal Foundry Model Intel 2025 Form 10-K
Manufacturing scale and reported figures
TSMC reported 15.0 million 12-inch-equivalent wafer shipments in 2025 and more than 17 million 12-inch-equivalent wafers of annual capacity that year. Shipments measure output over the year; annual capacity is a measure of manufacturing capability, so the two figures should not be treated as interchangeable. TSMC also reported that 74% of its wafer revenue in 2025 came from advanced technologies, defined in its report as 7-nanometer and beyond. TSMC 2025 Annual Report
Intel’s 2025 filing describes a different stage of business development: external foundry work is limited, and leading-edge process development is capital intensive. Intel reported that 18A entered high-volume production in 2025 and said it was seeking to establish the node as significant for government and enterprise foundry customers. The stated production milestone does not by itself show how much external customer volume Intel has secured.
Rank #4
Intel also says 14A, its first process designed from inception for external customers, requires wafer volumes beyond what it expects from its own products to achieve economic efficiency. It may pause or discontinue 14A and later leading-edge development if it cannot secure a significant external customer. This links the roadmap to the commercial challenge: a node’s technical development and production plans need enough committed demand to support its economics. Intel 2025 Form 10-K

TSMC’s 2025 report describes operating manufacturing in Taiwan and through subsidiaries or affiliates in the United States, Japan, and China; it describes the Dresden, Germany fab as under construction. The company also discusses fab expansion plans in Arizona, Japan, and Germany. Planned projects should not be counted as operating capacity. TSMC 2025 Annual Report
Best Value
Intel’s 2025 filing reports changes to its expansion plans: construction of its Ohio fab was slowed, and planned expansions in Germany and Poland were discontinued. Those adjustments matter to customers evaluating geography and supply resilience, but they are not a direct measure of current output or an apples-to-apples comparison with TSMC’s capacity.

What a chip designer should compare before choosing
Neither company should be treated as an interchangeable supplier based only on the word “foundry.” A prospective customer needs to match its design, schedule, and risk requirements to the specific services and production status on offer.
- Process and design ecosystem: Confirm that the required process node is available for the design and that design-enablement support fits the project.
- Production readiness and volume: Establish the expected production schedule, the volume the supplier can support, and whether the relevant process has reached the required manufacturing stage.
- Packaging and chiplet needs: Compare wafer fabrication with the packaging and integration services required; Intel lists packaging and chiplet integration among its external offerings.
- Geography and resilience: Distinguish operating sites from announced or under-construction facilities, and assess the locations relevant to the customer’s supply plan.
- Commercial and information safeguards: For a supplier that also sells chips, examine the actual contractual, data, and intellectual-property protections relevant to the design.
The cited company disclosures describe business structures, reported offerings, and stated plans. They do not independently compare customer experience, yields, prices, design portability, or market share. Financial figures also need care: TSMC’s 2025 consolidated revenue and gross margin are company-wide, while Intel Foundry is a segment within a company that also sells products. Those measures do not, by themselves, establish which foundry is more profitable. TSMC 2025 Annual Report Intel 2025 Form 10-K
The business-model distinction in one sentence
TSMC is a dedicated supplier built around customers’ designs; Intel is a chipmaker that manufactures primarily for its own products while trying to grow an external foundry business. That difference shapes customer breadth, potential competitive conflicts, service scope, and how much of each company’s manufacturing model depends on outside demand.
