start for 3 nanometers at TSMC

Mass production of the first chips engraved at a fineness of 3 nanometers will begin this week at TSMC, DigiTimes reports. Initially planned for 2022, this new stage in the miniaturization of processors should allow an improvement in energy efficiency. Two years ago, the Taiwanese founder promised a 25% to 30% drop in consumption or a 10% to 15% increase in performance compared to 5 nanometer engraving, all on a 42% more compact chip. . TSMC is the only manufacturer of Apple Silicon chips: 3-nanometer chips could notably benefit the iPhone, iPad and Mac.

On the iPhone side, it is unsurprisingly the Apple A17 chip which should benefit from it next September on the iPhone 15 Pro to succeed 4 nanometers of the Apple A16 chip. On the side of the iPad and the Mac, the future Apple M3 chip could equip the first models from the end of 2023 to succeed the 5 nanometers of the Apple M2 chip. There remains the unknown of the highly anticipated M2 Pro and M2 Max chips, which are to integrate the 14- and 16-inch MacBook Pros in the spring: the rumors on this subject are contradictory and the suspense remains.
