An Apple worker on Linked In is supposedly the supply of a brand new report that claims Apple has began designing chips that will likely be constructed utilizing TSMC’s next-gen 2nm course of node. Leaked slides revealed on the Korean web site gamma0burst and posted by way of a tweet on “X” by
leaker Revegnus (by way of MacRumors) the closely redacted Apple slide refers to older 5nm chips such because the A15 Bionic, 3nm chips such because the A17 Professional, and a future 2nm chipset.
As the method node used to construct a chip “shrinks” in measurement, the options of the chip get smaller together with the transistors permitting extra of them to suit inside a chip. That’s essential as a result of the upper a chip’s transistor depend, the extra highly effective and/or energy-efficient that chip is. The iPhone 15 Professional and iPhone 15 Professional Max are presently the one smartphones powered by a 3nm chip.
Closely redacted slide reveals that Apple is designing 2nm chipsets
Later this yr, Apple is predicted to make use of 3nm software processors (AP) for all 4 iPhone 16 fashions. The iPhone 16 and iPhone 16 Plus may very well be powered by the 3nm A18 Bionic AP whereas the iPhone 16 Professional and iPhone 16 Professional Max will sport the extra succesful A18 Professional AP. Each parts will likely be constructed utilizing TSMC’s second-generation N3E 3nm node.
TSMC is supposedly planning to start out manufacturing of 2nm chips throughout the second half of 2025 with the foundry churning out 1.4nm chips in 2027. Apple is predicted to be the primary firm to acquire 2nm chips. The latter ought to ship 10% to fifteen% efficiency upgrades on the similar energy or use 25% to 30% much less energy working on the similar pace when in comparison with 3nm chips.
Apple is TSMC’s high buyer which is why it’s normally in a position to be the primary to obtain chips made by TSMC utilizing its newest course of node. Apple might want to make some design modifications with a view to reap the benefits of TSMC’s 2nm node which is able to characteristic Gate-all-around (GAA) transistors as a substitute of the presently used FinFET transistors.
Utilizing horizontal nanosheets positioned vertically, GAA transistors permit the gate to encompass the channel on all 4 sides decreasing present leak and growing the drive present. This ends in stronger electrical indicators between the transistors enhancing the efficiency of the chip. Again in December, TSMC confirmed off a prototype 2nm chip to each Apple and Nvidia.
