TSMC unveiled its A14 logic process on April 23, 2025, with production planned for 2028. The company says A14 could deliver up to 15% more speed at the same power, up to 30% lower power at the same speed, and more than 20% higher logic density than its N2 process. Apple is a plausible early customer, but neither TSMC nor Apple has confirmed an A14 iPhone, iPad, Mac, or Apple-designed chip.
What TSMC actually announced
At its North America Technology Symposium, TSMC announced A14 as a future manufacturing process for logic chips—not as a finished processor or consumer product. TSMC’s current roadmap targets production in 2028 and positions the process for smartphones, artificial intelligence, high-performance computing, automotive systems, and internet-of-things devices.

The announcement describes a foundry technology that customers can use to design their own chips. A product must still be designed, validated, manufactured in volume, packaged, and integrated into a device before consumers can buy it. TSMC’s announcement is available at TSMC’s April 23, 2025 release.
What the “1.4nm” label means
“1.4nm” is an industry shorthand for A14’s process generation. It does not mean that every transistor gate or other feature is literally 1.4 nanometers wide. Modern node names are commercial and generational identifiers rather than a single measurement that describes the entire transistor.

TSMC’s official name is A14; the company’s technology page is at tsmc.com’s A14 overview.
TSMC’s claimed gains over N2
TSMC compares A14 with its N2 process and gives three headline figures. They are company projections under specified comparison conditions, not independent benchmarks from shipping chips.
| Comparison with TSMC N2 | TSMC’s stated A14 result |
|---|---|
| Speed at the same power | Up to 15% higher |
| Power at the same speed | Up to 30% lower |
| Logic density | More than 20% higher |
These figures cannot be translated directly into a 15% faster iPhone or 30% longer battery life. Actual results depend on a chip’s architecture, workload, memory system, software, packaging, voltage targets, and thermal limits. “Logic density” also describes logic circuitry, not necessarily the density of an entire finished chip containing cache, memory, analog components, input/output, and other blocks.
How A14’s technology is intended to work
Second-generation nanosheet transistors
A14 uses TSMC’s second-generation nanosheet transistor structure. Nanosheets are a form of gate-all-around transistor in which the gate surrounds the conducting channel more completely than older FinFET designs. That stronger control can reduce unwanted leakage and help the manufacturer continue scaling performance and efficiency.
Recommended Free Tools
This is not TSMC’s first nanosheet process: the N2 family already uses the company’s first-generation nanosheet technology. A14 is described as a subsequent generation. TSMC’s 2026 shareholder materials provide the roadmap and transistor description in this PDF.
NanoFlex Pro standard cells
TSMC also introduced NanoFlex Pro, an evolution of the standard-cell architecture used to build digital logic. Standard cells are reusable circuit building blocks that chip designers assemble with electronic-design-automation tools and intellectual-property libraries.
TSMC says NanoFlex Pro is designed to improve performance, power efficiency, and design flexibility. Those libraries and design tools matter: a transistor process cannot deliver its full benefit unless customers can efficiently design, verify, and manufacture a real chip on it.
Why Apple is part of the story
Apple designs its own A-series and M-series processors and has historically been one of TSMC’s most important advanced-node customers. Its high-volume launches can help justify the cost of adopting a new process, while iPhone and Mac chips place a premium on performance per watt, die area, and thermal efficiency.

It is still an inference, not a product announcement. TSMC has not named Apple as A14’s first customer, and there is no public confirmation of an A14-based iPhone, iPad, Mac, or Apple-designed chip. MacRumors’ original coverage made the same distinction.
Do not confuse TSMC A14 with Apple A14 Bionic
Apple’s A14 Bionic is the processor introduced in 2020 and manufactured on a 5nm process. TSMC’s A14 is a future foundry node. The shared name does not indicate a technical or product connection.
Rank #3
When could Apple products using A14 appear?
TSMC’s 2028 target is a production milestone, not a guaranteed consumer shipping date. A realistic sequence is:
- 2028: TSMC aims to begin A14 production, subject to its roadmap remaining on schedule.
- Late 2028 or later: A customer would need design validation, process qualification, manufacturing ramp-up, packaging, and inventory preparation before broad product availability.
- Specific Apple timing: Unknown. No Apple product, chip, or model has been publicly tied to A14.
“In production” can also mean that wafers are being made before capacity is sufficient for a major iPhone launch. Apple could use A14 first in a high-margin processor or specialized component, adopt it selectively, or skip it for a product if cost, capacity, or performance gains do not justify the change.
Where A14 sits in TSMC’s roadmap
TSMC’s roadmap includes several process branches and enhancements rather than a simple annual replacement cycle.
| Process | Current roadmap timing or description |
|---|---|
| N2 | TSMC reported high-volume manufacturing in the fourth quarter of 2025. |
| N2P and A16 | Volume production is scheduled for the second half of 2026. |
| A14 | Production is planned for 2028. |
| A13 | Described as a direct A14 shrink, with production scheduled for 2029. |
The later A13 announcement does not establish that Apple will move from A14 to A13 immediately. A customer may prefer an earlier full-node design, a more mature derivative, or a different branch depending on performance, cost, capacity, and product schedules. TSMC discusses A13 in its 2026 roadmap update.

Performance and thermals
If a design achieves TSMC’s projected characteristics, Apple or another customer could put more compute into a similar power envelope, or maintain performance while reducing heat. That could help sustained workloads, but final behavior depends on cooling, software scheduling, memory bandwidth, and the architecture chosen by the chip designer.
On-device AI
TSMC positions A14 for AI and high-performance computing as well as smartphones. More efficient logic could allow additional neural-engine capacity or more frequent local inference without a proportional rise in power. AI performance also depends heavily on memory bandwidth, specialized accelerators, packaging, model software, and the workload itself.

Battery life
A lower-power chip could support longer battery life, higher performance at the same battery capacity, more on-device processing, or a thinner device. It could also be offset by a brighter display, a more demanding modem, heavier software features, or Apple choosing to spend the efficiency gain on performance. TSMC’s 30% figure is a same-speed chip-power claim, not a promise of 30% longer device battery life.
Cost and product segmentation
New-node wafers, design tools, intellectual property, validation, and early capacity are expensive. Higher transistor density does not guarantee a smaller final die if a manufacturer adds more CPU, GPU, neural-engine, cache, or connectivity functions. Apple could reserve A14 for premium products rather than deploy it across its entire range, and manufacturing savings do not automatically become lower retail prices.
What has not been announced
- The first A14 customer.
- The first Apple chip or product using A14.
- A specific iPhone, iPad, Mac, or launch year.
- A14 wafer pricing, available capacity, or independent benchmark results.
- Whether Apple will adopt the A13 derivative soon after A14.
Bottom line
A14 is a real TSMC process milestone with a 2028 production target and ambitious company-stated gains over N2. Apple is strategically well positioned to use it, but “Apple’s 2028 1.4nm chips” remains an expectation rather than a confirmed product plan until Apple or TSMC identifies a specific commitment.
