TSMC’s 2 nm production: The next clock generator for Apple, NVIDIA and AMD’s chip future?

Taiwan Semiconductor Manufacturing Company (TSMC) seems to have struck a nerve in the industry once again with its upcoming 2 nm production line. Even before mass production of the so-called N2 processes has taken off, demand is apparently exceeding that of previous generations – including the much-praised 3 nm node (N3), which currently forms the basis of numerous mobile SoCs and GPU solutions. It is therefore less of a surprise than a logical consequence of technological development with an industrial policy tailwind.

Demand at record level even before series production

According to Taiwanese sources (Ctee), clear trends are already emerging: The purchase contracts for the 2 nm wafers are filling up faster than planned. Customers such as Apple, AMD, NVIDIA and MediaTek are reportedly already in the queue. Apple is planning to integrate it into the iPhone 18, NVIDIA is to use the new process for its future Vera Rubin GPU architecture and AMD will be the first publicly known user with the Zen 6 series (Venice). The fact that three of TSMC’s largest customers are therefore relying on the new technology should also put pressure on the rest of the industry – with corresponding effects on pricing and margins.

Technological switch to GAAFET: more scope, less consumption

What makes the new production technology so interesting is the switch from FinFETs to so-called gate-all-around field-effect transistors (GAAFETs), implemented in the form of nanosheet transistors. These allow for more flexible optimization: either for increased performance or lower energy consumption. TSMC speaks of an increase in performance of around 10-15 percent compared to the current N3E process – with comparable or even reduced power consumption. The defect density, i.e. the error rate during production, is also reported to be on a par with 3 nm or 5 nm, which indicates a high level of process maturity.

Capacity bottleneck: wafer production expected to triple by 2027

Production capacity is once again likely to be a key bottleneck during the start-up phase. Towards the end of 2025, TSMC expects a monthly output volume of around 50,000 wafers. If everything goes according to plan, this figure could triple by 2027. In addition to expanding existing capacities in Taiwan, the company is also planning to start 2 nm production at its US plant in Arizona from 2028. The expansion outside Taiwan is likely not only a response to geopolitical risks, but also to pressure from Western governments for localized high-end chip production.

Price effects: Higher chip costs as a logical consequence

The change in technology is also likely to result in higher production costs for chip developers. Industry experts assume that companies such as Qualcomm, MediaTek and Apple will have to purchase their SoCs much more expensively in future – and, as usual, will pass on at least some of these costs to OEMs and end customers. While top-end smartphones have already reached prices above the 1,000 euro mark, the new 2 nm node could result in a further price shift upwards – provided the industry does not find itself in a margin battle.

Evolution, not hype

Although the terminology in many places is already tending towards a “gold rush”, it remains to be said that this is not the case: The introduction of 2nm technology at TSMC is an evolutionary step, not a disruptive one. The technological shift to GAAFETs was long expected, the performance gains are tangible but not revolutionary. The fact that demand is nevertheless so strong is less due to exuberant enthusiasm than to a clear economic calculation: if you want to be at the forefront, you have to book early – even if not every machine is calibrated yet.
