TSMC’s public disclosures show greater reported operating scale and a more specific near-term leading-edge schedule, while Samsung describes a broad portfolio spanning advanced GAA and FinFET logic, specialty processes, design services and integrated 2.5D/3D packaging. A chip company should choose only after matching its design to a qualified process, design kit, IP set, package flow, production date, location and binding commercial terms. Node names alone do not establish which option will deliver the lowest cost per good die or the safest launch.
The short answer for a chip company
TSMC and Samsung Foundry are both credible options for manufacturing advanced and specialized logic, but the public information available for each company is not symmetrical. TSMC’s 2025 annual report gives shipment, capacity, customer and process-roadmap figures. Samsung’s public foundry materials concentrate on process families, specialty capabilities, design enablement and packaging rather than period-matched operating metrics. That difference supports a clear conclusion about how to evaluate them, not a blanket ranking.

For a design that needs a specifically scheduled leading-edge node, a large existing production network and extensive reported customer volume, TSMC may be the easier starting point for an RFP. For a project that values Samsung’s GAA or FinFET options, specialty devices, ASIC services, or a tightly integrated package flow, Samsung may be a strong fit. The correct decision still depends on the actual chip, tape-out date, qualification requirements and supply agreement.

What TSMC publicly offers
Leading-edge roadmap
TSMC’s 2025 annual-report letter says, “Our 2-nanometer technology successfully entered high volume manufacturing in 4Q’25, with good yield, and we expect a fast ramp in 2026.” This is TSMC’s own statement about its process and outlook; it is not an independently audited comparison with Samsung. The same disclosure schedules N2P and A16 for second-half 2026 volume production and A14 for 2028.
TSMC also reports that 3-nanometer technologies generated 24% of its wafer revenue in 2025. A revenue share is not the same as a share of physical wafers, available capacity or a guarantee that a new customer can obtain a slot. A buyer must verify the exact process version, design-rule manual, process-design-kit maturity, IP qualification and committed ramp date.
Scale and breadth
For calendar 2025, TSMC reported 15.0 million 12-inch-equivalent wafer shipments, 305 distinct process technologies, 12,682 products and 534 customers. It said advanced technologies—7 nanometers and below—accounted for 74% of total wafer revenue. These figures use TSMC’s definitions and reporting period; they should not be compared with an unstated Samsung denominator.

TSMC also said its annual manufacturing capacity exceeded 17 million 12-inch-equivalent wafers in 2025. The company identifies manufacturing operations in Taiwan and subsidiaries in China, the United States and Japan, and discusses a planned specialty fab in Germany. Capacity at the corporate level does not tell a buyer how many wafers are available on a particular node, in a particular fab, during a particular quarter.
Advanced packaging
TSMC lists development and production work involving CoWoS, InFO, SoIC and COUPE. These names represent different package and integration approaches rather than interchangeable products. A chiplet or high-bandwidth-memory design must confirm package capacity, substrate supply, memory integration, thermal limits, assembly and test ownership, and the date on which the complete package flow is qualified.
What Samsung Foundry publicly offers
Logic and specialty process families
Samsung describes a portfolio that includes gate-all-around (GAA), FinFET, fully depleted silicon-on-insulator (FD-SOI) and planar process categories. It also lists specialty options for radio-frequency designs, embedded nonvolatile memory, high-voltage devices, BCD power-management circuits, image sensors and fingerprint sensors. The presence of a category on a public page does not prove that every variant is available for a new design, at the required voltage, temperature range or production location.
SAFE design ecosystem
Samsung’s SAFE resources are described as including electronic-design-automation and design-methodology support, semiconductor IP, a cloud-based design environment and ASIC design services. Those services can reduce the integration burden for a company without a large internal physical-design or manufacturing team. The practical questions are which IP blocks are qualified on the selected process, which EDA tool versions are supported, how much porting is required, and what engineering and non-recurring costs are included in the engagement.

Packaging and heterogeneous integration
Samsung describes integrated 3D and 2.5D packaging and heterogeneous integration. For a multi-die product, the foundry decision therefore includes more than front-end transistor fabrication. Ask whether the proposed package supports the required die-to-die interface, memory stack, power delivery, thermal design, assembly sequence, known-good-die strategy and electrical test coverage. Public capability descriptions do not establish package capacity or a customer’s guaranteed delivery date.
Why “2 nm” and “3 nm” are not a head-to-head score
Process-node labels are manufacturer names, not a normalized measurement of transistor dimensions. A 2-nanometer designation from one foundry cannot be treated as physically identical to a 2-nanometer designation from another. Density, performance, leakage, SRAM behavior, design rules, standard-cell libraries and usable voltage ranges can differ substantially.
Compare the data that affects the finished design instead:
- Target frequency, active power, standby leakage and thermal-design power at the intended voltage.
- Standard-cell density, SRAM bit-cell options, analog behavior and available design-rule pitches.
- Design-kit revision, model accuracy, library characterization and sign-off requirements.
- Qualified CPU, GPU, accelerator, interface, memory and security IP for the exact process.
- Expected yield at the chip’s die size and redundancy strategy, supplied as a contractual planning assumption rather than a marketing adjective.
- Mask count, reticle limits, wafer cost, packaging cost and cost per good packaged die.
A credible comparison requires running the same design or a carefully normalized test vehicle through each foundry’s approved flow. Neither company’s public pages provide such a benchmark.

Capacity, geography and supply resilience
TSMC’s reported network gives a buyer several named manufacturing geographies, but the relevant question is not how many countries appear in a corporate report. It is where the selected process is actually manufactured and whether a second qualified source exists. Moving a design between fabs can require a new qualification, altered design rules, different models or a new package and test flow.
Samsung’s public description of a global network and its identification of Samsung Austin Semiconductor similarly do not establish that every process family is available at every site. Request the exact fab, clean-room capacity, planned tool additions, utility constraints, logistics route and business-continuity plan for the product.
Supply resilience should be measured at the product level. A company can have a large corporate capacity figure yet offer little near-term allocation on a fast-growing node. Conversely, a specialty process with modest total volume may have a dependable long-term slot. Require a written capacity commitment, ramp milestones, allocation rules during shortages and remedies if the schedule slips.
Design enablement can outweigh a nominally newer node
Foundry selection becomes expensive when a design team discovers late that an interface, memory compiler, analog block or safety requirement is not supported. Before choosing a node, build an IP and tool matrix covering:
Do these 3 things before closing this tab:
1Fix the driver behind crashes, sound loss and screen glitches2Clear out junk files and repair common Windows errors3Scan for outdated or missing drivers - takes under a minute- Standard-cell, SRAM, nonvolatile-memory, high-voltage and analog libraries.
- SerDes, PCIe, USB, networking, display, security and other interface IP needed by the product.
- Third-party IP licenses, ownership of modifications and responsibility for silicon validation.
- EDA versions, extraction decks, timing and power models, physical-verification rules and sign-off reports.
- Cloud or on-premises design-environment requirements, data-residency rules and access for external contractors.
Samsung explicitly describes SAFE support across EDA, methodology, IP, cloud design and ASIC services. TSMC’s reported breadth of process technologies and customers indicates a large ecosystem, but the only useful measure for an individual project is whether the required blocks are qualified and supported on the selected process revision.
Packaging is part of the manufacturing choice
For advanced accelerators, networking silicon and chiplet products, package availability can determine the launch date. Compare the complete flow:
- Define die count, die-to-die protocol, memory type, bandwidth, power delivery and thermal envelope.
- Confirm whether the foundry or a partner owns substrate procurement, assembly, burn-in and final test.
- Obtain package design rules, interposer or bridge limits, warpage specifications and known-good-die requirements.
- Check package and memory capacity quarter by quarter, not only at the corporate level.
- Model cost per shipped package, including assembly yield, test time, substrate, reticle and rework exposure.
TSMC’s named CoWoS, InFO, SoIC and COUPE work and Samsung’s described 2.5D/3D integration show that both companies address advanced packaging. Neither set of public descriptions, by itself, proves that a particular configuration has open capacity or production qualification.
Economics: the quote must be broader than wafer price
A lower quoted wafer price can still produce a higher product cost if yield, die size, masks, package losses or engineering work differ. Request a cost model that separates:
- Wafer price by process revision and committed volume.
- Mask set and reticle costs, including engineering lots and revisions.
- Design enablement, IP, cloud, ASIC and non-recurring engineering charges.
- Expected wafer sort, assembly, final-test and package costs.
- Yield assumptions by die size, with learning milestones and the definition of a good die.
- Capacity reservation fees, minimum commitments, take-or-pay terms and cancellation rights.
- Expedite charges, schedule penalties, quality remedies and allocation treatment during shortages.
TSMC and Samsung’s public disclosures do not establish comparable prices, yields, customer-specific delivery performance or commercial terms. Treat any estimate from a sales discussion as a project-specific quotation, not a general foundry ranking.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.How to run a fair TSMC-versus-Samsung evaluation
1. Freeze the product requirements
Write down die size, transistor and memory needs, performance, power, voltage, temperature, reliability grade, interfaces, package, annual volume, launch quarter and target markets. Include export-control, automotive, medical or defense requirements that may restrict a fab or supplier.
2. Shortlist process candidates by capability
Map the design to each candidate’s process family rather than comparing marketing node names. Eliminate any option lacking qualified SRAM, analog, RF, high-voltage, security or interface IP that the product requires.
3. Request matched design kits and test vehicles
Obtain the current process-design-kit revision, design rules, libraries, models, reliability data and test-chip results under appropriate confidentiality terms. Record the date and revision because schedules and collateral change.
4. Verify the tape-out-to-production path
Ask for milestones from design enablement through mask release, engineering wafers, wafer sort, package qualification, reliability testing and volume ramp. Distinguish a company’s announced schedule from a date contractually committed to your program.
5. Compare the entire supply chain
Identify the actual fab, wafer source, package house, substrate and memory suppliers, test locations and logistics routes. Require a continuity plan for earthquakes, power events, export restrictions, transportation disruptions and single-source components.
6. Normalize the financial model
Use the same volume, die size, package, yield curve, mask revisions, test coverage and exchange-rate assumptions for both quotations. Compare cost per good shipped unit over the product’s life, not the first wafer invoice.
7. Negotiate measurable commitments
Put capacity, ramp dates, quality limits, change-control procedures, notification periods, failure analysis, confidentiality, audit rights and remedies into the supply agreement. A process announcement is not a capacity reservation.
Which choice fits common project profiles?
A leading-edge high-volume logic product
Start with the foundry whose required node has a verified design kit, qualified IP and a production slot aligned with the launch. TSMC’s reported N2 status and 2026–2028 roadmap provide concrete dates to investigate. Samsung should remain in contention if its offered process meets the performance, power, IP and schedule requirements, but the buyer must obtain a directly comparable commitment.
A specialty or mixed-signal product
Evaluate device options first. Samsung’s listed RF, embedded-memory, high-voltage, BCD, image-sensor and fingerprint-sensor categories may be relevant. TSMC’s mature-node specialty work may also fit. The deciding evidence is process-specific qualification, analog performance, reliability and lifetime support—not the smallest advertised node.
A chiplet or advanced-package product
Compare package architecture, memory integration, thermal design, substrate allocation and test ownership at the same time as front-end silicon. A foundry with an attractive transistor process is not the right choice if the package cannot be qualified or supplied when needed.
A company with a small semiconductor team
Give extra weight to design-service scope, IP availability, cloud access, methodology support and escalation paths. Samsung’s SAFE description directly addresses these categories. Any comparable TSMC engagement should be evaluated by the same checklist and priced transparently.

Samsung’s public material does not provide a like-for-like number for TSMC’s 2025 shipments, annual capacity, customers, advanced-technology revenue share or process count. It also does not establish comparative yields, wafer prices, customer satisfaction, allocation priority or delivery performance. That absence is not evidence that Samsung lacks capacity, customers or competitive technology; it means the metrics are not presented on a matching basis here.
Likewise, TSMC’s statement that N2 entered high-volume manufacturing with “good yield” is a company claim about its own process. It should not be converted into a claim that TSMC’s yield is better than Samsung’s. Independent, period-matched test data or customer-specific manufacturing results would be needed for that conclusion.
Bottom line
TSMC offers the stronger publicly documented picture of 2025 scale and a dated near-term leading-edge roadmap. Samsung Foundry presents a broad alternative built around GAA and FinFET logic, specialty processes, SAFE design support and integrated advanced packaging. Neither profile alone answers the procurement question.
Choose the foundry that can prove, for your exact design, that the process kit and IP are ready, the package is qualified, the fab has committed capacity, the geography works for your supply chain and the contract protects cost, quality and schedule. Until those items are documented, declaring TSMC or Samsung the universal winner is not a technically defensible decision.
