The processor burning process will change. And this could directly impact users. Here’s why, and how

Apple is already designing its chips engraved with a precision of two nanometers . It was an employee of the company who leaked the information on the social network LinkedIn; This is probably an indiscretion on his part. We know that the manufacturer does not really appreciate seeing its new products published publicly before their official announcement.

Unsurprisingly, we assume that it is once again the founder TSMC which will be responsible for assembling motherboards with this new standard. We know that the company is also working to miniaturize its own production lines. As a reminder, today the latest generation iPhones are equipped with processors engraved in three nanometers. The M3 chips in Macs also display this advantage.

Be careful, however: knowing that Apple is working on this new feature does not mean that the iPhone 16 Pro will be entitled to it. We thus know that it is the previously arrived models which were equipped with three nanometers first (compared to four nanometers for Google’s Tensor G3), but the renewal rate here is several years in general. Sources speculate, however, that TSMC is also preparing 1.4 nanometer technology for 2027, so do the math. Within two to three collections of smart phones, energy consumption could be reduced. This is in fact one of the main advantages of reducing the fineness of the engraving.

Better performance on offer

Reducing the engraving fineness also improves the power of the devices. In theory, we can therefore estimate that possible iPhone 18 Pro will be 20 to 30% faster than their predecessors. To arrive at this figure, simply refer to the usual velocity gains shared by Apple when the manufacturer highlights its new chips. Of course, the name “iPhone 18 Pro” remains to be considered with caution – we do not yet know anything about these potential future high-end mobiles.

On the Mac side, rumors have already made it possible to hear about the generation of M4 chips as recently as this month . Please note, however, that we will have to wait a few more quarters to discover these components, which could also coincide with the transition to two nanometers. Until then, we will probably be able to discover the thirteen- and fifteen-inch MacBook Air M3s which could land in stores next spring. An announcement may be in the pipeline for the period from late March to early May, but the keynote has yet to be confirmed and a simple press release could also be issued instead.

A monstrous scale

In an Apple processor, there are hundreds of millions of transistors, capable of performing billions of operations per second. An engine with artificial intelligence is also included in the SoC ( system on chip ) of the Apple firm, perhaps soon ready to upgrade to thirty-two cores but limited to sixteen today.



The size of microprocessors of this type now reaches only a few tens of nanometers. For comparison, a virus measures about three hundred nanometers, compared to a thousand for a bacteria (one micrometer) or eighty micrometers for the thickness of a human hair.

The M3 processor, for its part, has an eight-core CPU and its graphics card has as many or even ten, depending on the configuration chosen by the buyer. A MacBook Pro already allows you to take advantage of this room, and it is rumored that iPad Pros with OLED panels will also be entitled to it in the coming weeks. Apple has, as usual, not confirmed the file, preferring to remain silent until a formal announcement.
