Semiconductor development is taking another big step forward. The company IBM introduced the first ever chip technology with a manufacturing process below one nanometer. The new architecture, called 0,7nm Nanostack promises significantly higher performance while consuming much less energy. If the technology can be mass-produced, it could change the way artificial intelligence, data centers, and future iPhones, Macs, and other common devices work.
Instead of growing in width, the chip grows in height
While today's processors place transistors side by side on a single plane, IBM has taken a completely different approach. Nanostack technology stacks transistors on top of each other, similar to building a skyscraper instead of a sprawling city. This allows significantly more computing elements to be placed on the same surface area. According to IBM, a chip the size of a human fingernail can fit almost 100 billion transistors. Their number is one of the main factors determining the performance of modern processors. According to the first laboratory results, the new architecture offers two very interesting possibilities. Manufacturers can gain up to 50% more performance, or conversely, maintain the performance of today's chips and reduce energy consumption by up to 70% compared to IBM's current 2nm technology. Energy efficiency is becoming one of the biggest challenges of the current generation of artificial intelligence. Modern AI models require enormous amounts of computing power and their operation consumes more and more electricity. Therefore, any significant reduction in consumption represents a significant step forward.
More space for AI
IBM has also redesigned the memory cells to take up less space than before. The freed-up space can be used by manufacturers to add more computing units or larger AI accelerators. This opens the way to more powerful processors without having to significantly increase their size. The practical impact could be huge. Future smartphones could handle more complex AI tasks on the device, laptops could offer higher performance with longer battery life, and data centers could handle more demands at lower operating costs. Although this is an extremely significant technological milestone, these chips are not yet available to consumers. IBM emphasizes that this is still a research project, not a product ready for mass production. Before the technology can be used in commercial processors, a number of manufacturing and economic hurdles will need to be overcome. However, if development continues as expected, the first chips using a similar architecture could appear within the next few years.

What does it mean for Apple?
Although Apple uses processors manufactured by TSMC, similar technological breakthroughs often determine the direction of the entire semiconductor industry. Apple has long been committed to the best possible performance-to-consumption ratio, which is essential not only for iPhones and Macs, but also for the development Apple IntelligenceIf sub-nanometer technology really does reach mass production, it could enable the creation of significantly more powerful chips in the future. Apple Silicon with longer battery life and even more advanced artificial intelligence functions right on the device. Just a few years ago, it seemed that further shrinking of manufacturing processes would hit physical limits. IBM is now showing that innovation does not have to lie only in shrinking transistors, but also in completely new chip designs. If the Nanostack concept proves itself in practice, it could become one of the most important technological breakthroughs of this decade.
