Much of the evolution of processor power and performance in recent years is due to successive reductions in the size of their transistors. A reduction that allows more power, less consumption and less heat generation by being able to put more in the same processor. A reduction which, according to DigiTimes, will reach 3 nanometers in 2022.

More power and less consumption: this is the importance of the size of the transistors in a processor

While waiting for the announcement of the iPhone 13 presentation event, DigiTimes (via MacRumors) indicates that in 2022, Apple will start using 3nm processors. A change that will affect the future iPhone 14 and the rest of the company’s devices, including Macs.

“TSMC is on track to bring its 3nm process technology to volume production in the second half of 2022 for Apple devices, whether they are iPhones or Mac computers, according to industry sources.

Recall that less than a year ago, Apple presented us the first 5 nm processors, which are mounted on the current iPhone 12. To offer a comparison, it is expected that Intel, in 2022, will continue to be blocked in manufacturing 10 nm. process, which makes TSMC’s feat even more impressive.

Ultimately, the size of processors has a direct effect on the performance of a processor. If we reduce the size of the transistors, we can add more in the same space, so the power increases. By making transistors smaller and reducing the space between them, they require less electricity, thus reducing consumption. And finally, by reducing electricity consumption, less heat is released, which in turn helps to increase its power and reduce its consumption.

More computing power, less energy to operate and less energy wasted in the form of heat.

Getting back to Apple’s 3nm processors, the question that remains to be answered is which product will be the first to use this technology. According to Nikkei collected several weeks ago, 3nm will appear first on an iPad, probably Pro. Meanwhile, according to TrendForce, the 2022 iPhone will use a 4nm process, which DigiTimes also said shortly before switching to 3nm.

Whether it’s an iPad or an iPhone first, the truth is that the new 3nm processor manufacturing system will reach all Apple devices, including Macs with Apple silicon. We don’t know if we’ll be talking about an M1X, M2, or M2X when the jump is made, what we do know is that the awesome power and low consumption that surprised us all with the new Macs with M1 will take a huge step forward.

It’s easy to overlook these details, but the amount of technology behind the processors lithography that we use in our devices on a daily basis is enormous. Let’s talk about four, three or two nanometers, what is clear is that we will notice an important difference.
