TSMC says its N2 2nm process entered volume production in the fourth quarter of 2025, with good yield and a fast 2026 ramp. Samsung Foundry’s SF2 reached mass production in 2025, and Intel Foundry’s 18A entered production in 2025 and high-volume manufacturing late that year. All three are credible 2nm-class competitors, but their node names are not directly equivalent measurements.
The practical distinction is manufacturing maturity and breadth. TSMC publicly reports a much larger customer base, product count, technology portfolio and wafer-capacity footprint than either rival. Samsung and Intel have technically ambitious leading-edge processes, yet the public evidence supplied for this comparison does not establish equivalent external-customer volume or independently comparable yield data.

The short answer: TSMC leads on demonstrated scale
There is no single statistic that proves which foundry makes the “most advanced” chip. A process can be impressive on a transistor diagram but still be difficult to qualify, yield or supply in volume. For a chip company, the winning foundry must combine a leading transistor technology with predictable yield, design tools, packaging, capacity and the ability to ship large quantities to many customers.
On the public evidence available through 2025 and early 2026, TSMC has the clearest lead on that complete manufacturing proposition. Its N2 process started volume production in 4Q25 as planned. TSMC’s 2025 annual report says N2 “successfully entered high volume manufacturing in 4Q’25, with good yield,” and that the company expects a fast ramp in 2026. The same year, TSMC reported 12,682 products, 305 distinct technologies, 534 customers and more than 17 million 12-inch-equivalent wafers of annual capacity.
#1 Best Overall
Samsung and Intel should not be dismissed. Samsung labels SF2 as having started mass production in 2025 and bases it on a second-generation MBCFET gate-all-around architecture. Intel identifies 18A as its most advanced leading-edge node, says it entered production in 2025 and reports that high-volume manufacturing began in late 2025. Those milestones make both genuine challengers. They do not, however, provide the same public proof of broad external-customer scale that TSMC provides.
Therefore, the defensible ranking depends on the question:
- Most proven combination of advanced process and customer-scale manufacturing: TSMC N2.
- Most advanced Samsung process in production: Samsung SF2.
- Most advanced Intel process in production: Intel 18A.
- Smallest physical transistor or best yield: not established by a consistent public comparison.
Why “2nm” and “18A” cannot be ranked by the label alone
Foundry node names are generation labels, not standardized measurements of one physical feature. A “2nm” designation from one supplier does not mean every transistor dimension is 2nm, nor does it automatically correspond to another company’s “18A.” Density, libraries, transistor design, interconnects, power delivery and design rules all affect the resulting chip.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
TSMC calls its generation N2. Samsung calls its leading process SF2, short for its second-generation 2nm-class family. Intel calls its process 18A, using its own angstrom-based naming system. Comparing those names as if they were measurements from the same ruler can produce a false winner.
A fair comparison asks what each node can deliver in a real product: performance at a specified power envelope, energy efficiency, usable logic density, memory and analog options, design enablement, packaging, yield and available wafer capacity. The supplied official disclosures do not provide one audited table covering all of those metrics for all three companies.
Production status at a glance
| Foundry | Leading process discussed here | Public production milestone | What the evidence establishes | What it does not establish |
|---|---|---|---|---|
| TSMC | N2 (2nm) | Volume production began in 4Q25; high-volume manufacturing with good yield reported by TSMC | A planned 2025 volume start and a fast 2026 ramp expectation | An apples-to-apples yield, price or density comparison with Samsung and Intel |
| Samsung Foundry | SF2 (2nm-class) | Mass production started in 2025 | A second-generation MBCFET gate-all-around process is in production | Independently comparable yield or external-customer volume figures |
| Intel Foundry | 18A | Production began in 2025; high-volume manufacturing began in late 2025 | Intel’s most advanced leading-edge node reached production and HVM | The same external-foundry customer scale TSMC reports |
“Mass production,” “volume production” and “high-volume manufacturing” are closely related business milestones, but the terms are used within each company’s reporting system. They should not be treated as proof that the three lines were shipping identical quantities to identical types of customers.
TSMC N2: the strongest case for manufacturing maturity
What entered production
TSMC’s official 2nm information says, “TSMC’s 2nm (N2) technology has started volume production in 4Q25 as planned.” Its 2025 annual report adds that N2 successfully entered high-volume manufacturing in the same quarter, with good yield, and that TSMC expects a fast ramp in 2026. Those statements answer the most important risk question for a leading-edge process: it moved beyond an announcement or pilot line into volume manufacturing.

Why the ecosystem matters
TSMC’s reported 2025 scale is unusually detailed. It made 12,682 products using 305 distinct technologies for 534 customers and had annual capacity above 17 million 12-inch-equivalent wafers. Those figures cover the company’s overall manufacturing operation, not N2 alone, so they should not be read as N2-specific shipment totals. They do show the breadth of the organization that supports a new node: many product types, process variants, customer programs and fabs operating across a large base.
That breadth reduces a customer’s dependence on a single design pattern. A chip team may need a leading-edge logic die, a less advanced companion die, specialized input/output, analog functions or a package assembled from several process generations. A foundry with a broad portfolio can coordinate more of those requirements. TSMC’s 305-technology figure is evidence of portfolio breadth, not a guarantee that every design will receive the same economics or schedule.
Business momentum and capacity context
TSMC’s shareholder letter says that, concluding 2025, the Foundry 2.0 industry increased 16% year over year. TSMC also reported 35.9% revenue growth in US-dollar terms for 2025. These are company-reported figures and describe market and financial performance rather than transistor quality. They matter because leading-edge manufacturing requires sustained capital investment, engineering staffing and the ability to expand capacity as customers move from tape-out to shipment.
The more than 17 million 12-inch-equivalent wafers of annual capacity is also an all-company figure. It should not be interpreted as the amount of N2 capacity available to one customer. Nevertheless, it is the clearest public scale indicator among the three companies in this comparison.
Rank #2
Samsung Foundry SF2: a real 2nm-class challenger
Production milestone and transistor architecture
Samsung’s logic-node information labels SF2 “Started mass production in 2025.” Samsung describes SF2 as building on a second-generation MBCFET foundation. MBCFET is Samsung’s name for its gate-all-around transistor approach, in which the gate surrounds the active channel more completely than in a conventional fin-based transistor.
Gate-all-around designs can provide tighter control of the channel and help manage leakage as dimensions shrink. That architectural choice is technically significant, but architecture alone does not reveal how a process performs in a customer’s product. The relevant outcomes still include usable libraries, design-rule stability, yield across different circuit types and the ability to supply wafers consistently.
What is known and what remains unproven publicly
Samsung’s public pages establish that SF2 reached mass production in 2025 and that the company’s foundry portfolio extends from 180nm to 2nm and beyond, with EUV and GAA milestones. The cited pages do not provide a directly comparable, independently audited yield table or an external-customer volume breakdown.
That limitation does not mean SF2 is unsuccessful. It means a reader should avoid claiming that Samsung has the best 2nm yield, the highest density or the largest customer shipment volume based only on the available official material. Samsung has a credible production node; the scale and quality comparison remains less transparent than TSMC’s published overall figures.
Where Samsung can be strategically important
A second supplier with a production-ready 2nm-class process can be valuable even when it is not the volume leader. Customers may seek a negotiating alternative, geographic diversification, a different transistor implementation or access to Samsung’s own logic, memory and packaging capabilities. Those are strategic reasons to evaluate SF2, but they do not substitute for product-specific qualification data.
Intel Foundry 18A: ambitious technology with late-2025 HVM
Intel’s stated production timeline
An Intel VLSI Symposium update says, “Intel 18A, Intel Foundry’s leading-edge process node, entered into production in 2025.” Intel’s 2025 Form 10-K says 18A “first went into high-volume manufacturing in late 2025” and calls it Intel’s most advanced leading-edge node.
That is a meaningful change from a process that exists only on a roadmap. Intel’s disclosure establishes production and HVM timing. It does not, by itself, show how many external foundry customers were shipping products on 18A or how its yield compares with N2 or SF2.
Why Intel’s evidence is harder to compare
Intel has historically designed and manufactured many of its own processors, while its foundry strategy also seeks external customers. A company’s internal product ramp and an open-foundry customer ramp involve different qualification, support and volume patterns. Intel’s public 18A statements confirm technical and manufacturing progress, but the cited evidence does not establish TSMC-like external-customer scale.
For a prospective customer, the practical questions are whether the required process design kit is ready for the intended product, whether intellectual-property blocks have been validated, what package options are available, and what capacity and yield commitments can be documented for that program. Those answers are contract- and product-specific rather than inferable from the 18A name.
Yield: who has the best 2nm process?
No defensible public answer ranks all three companies’ 2nm-class yields. TSMC is the only one of the cited sources to explicitly describe N2 as entering high-volume manufacturing “with good yield.” That is positive evidence, but it is not a numerical yield percentage and it is not measured under a common test-chip methodology.
Samsung’s SF2 production announcement and Intel’s 18A production disclosures establish manufacturing status, not a comparable yield number. Yield can also vary by design: a simple test structure, a dense cache, a large AI accelerator and a mixed-signal chip stress different parts of a process. Early yields may improve as equipment, recipes, libraries and defect learning mature.

- Samsung and Intel have not supplied, in the cited material, a directly comparable public yield result.
- “Best yield” cannot be awarded as a numeric cross-company fact from these disclosures.
Which foundry makes the smallest chips?
The node labels do not support that claim. N2, SF2 and 18A represent competing process generations, but each company defines and markets its nomenclature differently. A smaller label is not proof of smaller gate pitch, metal pitch, standard-cell height or total transistor area.
If “smallest” means the most advanced commercial generation, all three have a credible claim to 2nm-class or equivalent leading-edge production in 2025. If it means the highest transistor density in a specific logic library, the supplied evidence does not provide a common measurement. If it means the smallest finished chip package, that is primarily a product-design and packaging question rather than a foundry-node label.
Performance per watt and density: why the public record is incomplete
Leading-edge announcements often discuss performance, power and area improvements relative to a company’s previous generation. For this comparison, however, the cited official material does not provide one consistent table of density, maximum frequency, energy per operation or performance-per-watt results for N2, SF2 and 18A.
Even when two vendors publish numbers, the comparison can be distorted by different voltage targets, libraries, SRAM assumptions, interconnect stacks, test circuits and baseline nodes. A process may be excellent for a high-performance CPU but less advantageous for a very large accelerator or a design with extensive analog content.

Customer scale, tape-outs and volume shipments
TSMC’s disclosed breadth
TSMC’s 2025 totals—12,682 products, 305 technologies and 534 customers—are the strongest public indicators that its manufacturing platform operates at broad commercial scale. They describe the whole company rather than N2 alone, but they demonstrate a mature customer and technology ecosystem around the introduction of new nodes.
Samsung and Intel’s public gap
The supplied Samsung and Intel sources do not disclose an equivalent table of external customer counts, product counts and annual wafer capacity for their leading-edge foundry operations. That absence should be treated as an evidence gap, not proof that no customers or volume exist. It does mean that a reader cannot responsibly infer parity with TSMC’s reported scale.
“Tape-out” is another term that needs care. A tape-out shows that a design was finalized for manufacturing; it does not prove high-volume shipment, profitable yield or long-term supply. A volume-shipment comparison would require customer-specific disclosures or independent shipment data that are not provided here.

Modern AI processors are systems of dies, high-bandwidth memory, interposers or bridges, power delivery and thermal solutions. The most advanced logic wafer is only one part of that system. Foundry selection therefore includes the ability to connect multiple dies, test known-good-die, manage warpage and thermal constraints, and coordinate package qualification with wafer production.
Advanced-packaging integration is an important comparison axis, but the cited company disclosures do not provide a consistent set of packaging capacities, package yields, customer volumes or delivery dates for all three foundries. It would be inaccurate to declare one company the universal packaging leader from the cited evidence alone.
Rank #4
For AI-chip buyers, the practical evaluation should cover the complete stack:
- Logic-node qualification for the compute die and any companion dies.
- Memory interface capability and validated package construction.
- Reticle-size and die-size limits for the planned accelerator.
- Package and test capacity at the required shipment rate.
- Thermal, power-delivery and reliability qualification.
- Ability to expand from engineering samples to sustained production.
TSMC’s scale and broad customer ecosystem make it the safest general answer for an AI designer seeking a proven leading-edge manufacturing platform. That is a manufacturing-confidence conclusion, not proof that every AI chip will perform better on N2 than on SF2 or 18A.

Geographic capacity and supply resilience
Geography matters because customers may need supply outside a single region, continuity during disruptions and a second source for selected products. TSMC’s reported annual capacity above 17 million 12-inch-equivalent wafers indicates a very large global manufacturing footprint, although the cited figure is company-wide and does not identify the location or allocation of N2 wafers.
Samsung and Intel also operate substantial manufacturing organizations, but the supplied material does not give a like-for-like geographic capacity table for their leading-edge foundry output. A customer should ask each vendor for the exact fab location, qualified node, expansion schedule, export-control implications, backup capacity and rules for transferring a design between sites.
Roadmap resilience and execution risk
A roadmap is credible when milestones move from research to process qualification, design enablement, risk production and then high-volume manufacturing. On that sequence, all three companies have reached a significant 2025 milestone: TSMC N2 volume production, Samsung SF2 mass production and Intel 18A production with late-2025 HVM.
Execution risk remains different from announcement risk. A customer still has to confirm:
- Whether the exact process variant needed is available, rather than only the headline node.
- Whether the design kit and third-party intellectual property are production qualified.
- Whether wafer starts and package capacity match the forecast.
- Whether yield learning is sufficient for the customer’s die size and defect sensitivity.
- Whether the next process generation can be introduced without forcing a disruptive redesign.
TSMC’s stated good yield and fast 2026 ramp provide the clearest public evidence of near-term execution. Samsung and Intel have reached production milestones, but the available disclosures reveal less about the breadth and repeatability of external-customer ramps.
Decision guide: which foundry fits which priority?
| If your priority is… | Most defensible choice from the available evidence | Why | What to verify before committing |
|---|---|---|---|
| Highest confidence in a leading node already at customer-scale volume | TSMC N2 | Volume production in 4Q25, good yield reported by TSMC and the broadest disclosed ecosystem | Allocation, product-specific yield, wafer pricing and package capacity |
| A second 2nm-class source with GAA architecture | Samsung SF2 | Mass production began in 2025 and SF2 uses second-generation MBCFET | Independent yield data, design-kit maturity, customer references and capacity |
| Intel’s newest leading-edge process | Intel 18A | Production in 2025 and HVM in late 2025; identified by Intel as its most advanced node | External-customer ramp, package options, capacity commitments and yield by die type |
| Lowest physical dimensions or best performance per watt | Not established | Node labels and the cited disclosures are not directly comparable | Common test-chip data using the same definitions and conditions |
| Large AI accelerator production | Start with TSMC, then qualify alternatives | TSMC has the strongest public evidence of scale and ecosystem breadth | Advanced packaging, memory integration, thermal limits, test throughput and supply allocation |
How to compare the three foundries for a real design
- Define the product, not just the node. Document die size, transistor mix, SRAM content, frequency targets, voltage range, package type, expected annual units and acceptable defect rate.
- Request equivalent technical data. Ask each foundry for process design kits, standard-cell libraries, memory compilers, design rules, reliability limits and performance models for the same design assumptions.
- Separate wafer evidence from package evidence. Confirm wafer yield, package yield, test coverage and final-good-unit yield independently.
- Check the ramp plan. Get dates for risk production, qualification, engineering samples, first customer shipments and high-volume allocation. Confirm whether the dates apply to the exact process variant.
- Model total cost. Include masks, engineering wafers, wafer price, test, packaging, reticles, redesign risk, inventory and the cost of a second source. A lower quoted wafer price can be outweighed by weaker yield or delayed capacity.
- Qualify supply resilience. Verify fab locations, backup sites, export restrictions, allocation rules and the process for moving a design to another qualified facility.
- Use independent silicon evidence when available. Compare chips built under matched conditions, not marketing claims based on different libraries, voltages or workloads.
Answers to the questions readers ask most
Is Intel 18A ahead of TSMC N2?
The public evidence does not support a blanket “ahead” verdict. Intel 18A entered production in 2025 and high-volume manufacturing in late 2025; TSMC N2 entered volume production in 4Q25 with good yield reported by TSMC. The node labels are not equivalent, and the cited sources lack a common density, performance, power and yield test. TSMC leads on demonstrated ecosystem scale; Intel 18A is a credible technical and manufacturing challenger.
Can Samsung 2nm compete with TSMC?
Yes. Samsung SF2 started mass production in 2025 and uses a second-generation MBCFET gate-all-around architecture, so it is a genuine 2nm-class production offering. The available public material does not show that Samsung matches TSMC’s disclosed customer count, technology count, wafer capacity or externally comparable yield evidence.
Who can manufacture the most advanced AI chips?
TSMC is the strongest general answer because N2 is in volume production and TSMC reports the broadest manufacturing and customer ecosystem. An individual AI product could still favor Samsung or Intel after evaluating its die size, package, memory interfaces, design kit, capacity contract and yield. No cited source proves that one foundry delivers the best performance for every AI architecture.
Does TSMC’s 17-million-wafer figure mean it can supply 17 million N2 wafers?
No. The more than 17 million 12-inch-equivalent wafers figure is TSMC’s total annual capacity across its manufacturing operation in 2025. It is not an N2-only allocation or a promise to any individual customer.
What should a buyer ask for before choosing a foundry?
Ask for product-specific yield and capacity commitments, process-design-kit readiness, validated intellectual-property blocks, wafer and package pricing, qualification schedules, advanced-packaging capability, fab location, backup capacity and the conditions for a second source. Those documents are more useful than comparing “2nm” and “18A” as isolated labels.
