Intel recently stated that it is completely changing the way in which generations of its microprocessors have been defined, discussed, and evaluated, paving the way for chips to be measured in angstroms, not nanometers.
Specifically, Intel is rewriting the terminology associated with its process technology, it said at an “Intel Accelerated” presentation. Going forward, Intel’s 10nm “enhanced SuperFIN” technology will now be called “Intel 7,” mentally placing it on the same tier as the same 7nm process technology AMD uses for its Ryzen chips. Intel began signaling this shift in March (go. pcworld.com/sgnl), but now it’s official.
It’s a branding exercise, but with technical reasons behind it. For years, one way in which chip giants like Intel and AMD have defined the evolution of their products has been through process nodes or process generations: first in terms of microns, then nanometers, such as the 14nm process Intel has struggled to move past. But what defines a 7nm process has become increasingly abstract, to the point at which some, like Intel, would argue that the term has become essentially meaningless. Instead, Intel will distinguish process nodes by a new metric: performance per watt.
Intel’s announcement includes three important components. For one, Intel is simply abandoning the traditional way of defining new process nodes, changing the way in which you’ll talk about its products. Second, the announcement charts the end of the nanometer era, and looks forward to defining chips based on angstroms. Finally, Intel has made a bold claim that it will regain what it calls “manufacturing leadership” by 2025.
THE NEW LANGUAGE OF INTEL’S CHIP MANUFACTURING
Intel’s manufacturing technologies will now be known as Intel 7, Intel 4, Intel 3, and then—moving on—Intel 20A. They will be primarily defined by how much they improve in performance per watt over the prior generation. An Intel representative added that they will also be defined with an “area improvement as a key technical parameter,” but said that the company wouldn’t be providing those numbers.
Traditionally, what we call the “process node” or “process technology” was just the length of the individual transistor gate, the fundamental building block of integrated circuits. As semiconductor manufacturing improved, the sizes of the individual gates shrank. That enabled Moore’s Law: the axiom that the number of transistors in a fixed area on a chip doubles every 18 to 24 months. But as ExtremeTech noted in a 2019 story (go.pcworld.com/xt19), the last time that the gate length matched the process node was way back in 1997. Instead, over time, chipmakers began essentially replacing actual gate lengths with equivalents, as the ways to compare manufacturing processes became increasingly complex, involving SRAM cell sizes, fin width, minimum metal pitch, and more. None of these factors, however, is ever used in general conversation.

Ask: Tech Support & Techsplanations
Like any new technology, we have much to learn about the working life of SSDs in M1 Macs. Alarming reports of rapid wear must be tempered against use. Take any low–end Intel Mac with limited memory and work it hard with high use of virtual memory, and its SSD wears out faster. Unlike rotating hard disks, which can keep spinning for a decade or more if you’re lucky, the more your Mac writes to an SSD, the shorter its life.
