Intel is bringing out the heavy guns in the form of third-generation Core Ultra processors, known as Panther Lake, which are based on 18A, or 1.8 nanometre, technology. On the other side of the market barricade is AMD with its Ryzen chips, baked in TSMC ‘s Taiwanese factories using a 3nm process. On paper, Intel’s advantage seems crushing, suggesting a technology almost half the size and more modern. However, in the CFO’s portfolio, this difference may prove to be a statistical error. In a world where ‘nanometre’ has become a brand rather than a measurement, business must learn to look at what really drives performance, ignoring the labels on the boxes.
When IT managers look at the specifications of new laptops or servers, their gaze naturally goes to the numbers, because in the technology industry, smaller usually means better, faster and more economical. Manufacturers are well aware of this, which is why the arms race in the semiconductor sector has moved from the physics labs to the marketing departments. To make an informed purchasing decision for 2025-2026, you need to understand where the engineering ends and the wordplay begins.
The grand illusion of the nanometre
For decades, the IT industry has operated with a simple and understandable currency. Back in 1995, when we talked about the 350 nm technology process, it meant that the gate of a transistor on a silicon wafer was actually 350 nanometres long. The engineer and the salesman spoke the same language, and the node name was a direct reflection of physical reality. However, this order broke down in the late 1990s with the introduction of new technologies for building microtransistors, which broke the direct link between the node name and the physical dimension of the components.
Today, names such as ‘Intel 4′, ’18A’ meaning 18 Angstroms, or ‘TSMC N3’ are predominantly trade names. Treating them as a technical measure of length is a mistake that can lead to misleading business conclusions. It is a situation analogous to the automotive market, where the model designation of a car, for example the BMW 330, no longer necessarily denotes a three-litre engine. The number now serves to position the product in the range, rather than to describe its technical parameters precisely.
For business, this means that the approach to analysing offerings needs to change. The fact that one processor is labelled ‘1.8 nm’ and another ‘3 nm’ does not automatically mean that the former is physically much smaller. In fact, the differences may be minimal and, in extreme cases, the packing density relationship may even be the opposite of what the numbers suggest.
The hard currency of silicon
Since nanometres are conventional, an informed investor or IT manager should look at other metrics. If we look under the hood of Panther Lake processors or the latest Ryzen processors, we find objective parameters that PR departments are reluctant to talk about, but which are crucial for engineers. These are, first and foremost, Gate Pitch, which is the minimum distance between individual transistors, and Metal Pitch, denoting the minimum distance between the copper paths connecting these components.
Analysis of this hard data leads to surprising conclusions. Comparing the current generation of processes, it appears that the Intel 4 technology and the competing TSMC N4 have almost identical physical characteristics, with a gate pitch oscillating between 50 and 51 nanometres. Despite the different trade names, the packing density of the technologies is very similar. The future looks even more interesting, with Intel promoting an 18A process suggesting 1.8 nm, while TSMC is preparing to implement a 2 nm process. Paradoxically, according to many technical analyses, it is the Taiwanese ‘2 nm’ that may offer higher transistor density than the US solution. Intel is making up for it with marketing, suggesting leadership, but in practice the two giants are going head to head and their nodes will meet each other halfway in terms of real-world performance.
Physics translates into costs
Although the labels are confusing, the technological advances are real and central to the cost of doing business, or TCO. Regardless of the nomenclature, the drive towards denser transistor packing is driven by the inexorable laws of physics, as a smaller transistor with a shorter path between source and drain requires a lower voltage to switch its logic state. For the company, this translates directly into energy efficiency and thermal performance.
The chip, made using a newer, denser process, uses less power for the same load. On the scale of a single laptop, this means an extra hour of battery life during a business trip, while on the scale of a data centre, it translates into thousands of zlotys of savings on electricity bills. The thermal aspect is equally important, as less power consumption means less heat generated. This allows the processors to run at higher frequencies without the risk of thermal throttling, ensuring more stable operation of demanding applications. Therefore, Intel Panther Lake will be inherently better than its predecessor not because of the name ’18A’, but because the engineers have actually improved the physical structure of the chip, which is also true for AMD using TSMC improvements.
The strategic trap of the single supplier
There is another element of business risk in this technological jigsaw puzzle, related to incompatibility. Intel’s, TSMC’s and Samsung’s manufacturing processes have diverged dramatically, with each giant using different chip production methods, deploying technologies such as FinFET or RibbonFET at different times. This means that chip designers such as AMD and NVIDIA are firmly tied to their chosen factory and cannot move production to a competitor overnight. Adapting a design to another factory is a process that takes up to a year and incurs huge costs. When choosing a hardware platform for a company, decision makers are therefore choosing not just a processor, but the entire supply chain, where the stability of the manufacturing partner becomes a strategic factor, more important than the marketing name of a nanometre.
We are approaching the point where comparing processors solely on the basis of lithography becomes pointless. Intel Panther Lake and the upcoming Ryzen generations will be powerful chips, but their value to business is not based on the labels on the box. When planning infrastructure purchases, the key indicator should be the performance-per-watt ratio. It is this parameter that determines whether an investment in new hardware will translate into real productivity gains and reduced operating costs for the business.
