Production of the iPhone 13 chip is about to begin, but if you are looking for game-changing efficiency, you may want to hold off on buying an iPhone this year.

Digitimes reports that Apple's A15 chip for the iPhone 13 will be in production in less than two months. However, since Apple's major chipset development is set for next year, there will reportedly be no major changes from the existing A14 chip.

As Digitimes reports, production of the A15 chip is scheduled to begin in May, giving Apple plenty of time to prepare the iPhone 13 for a September launch. Chipmaker TSMC will manufacture the chip, continuing its long partnership with Apple.

More exciting, however, is news of a 4-nanometer (4nm) chip that TSMC intends to begin manufacturing at the end of the year. This is one step smaller than the current 5nm A14 and the upcoming A15, meaning that Apple will be able to pack in even more transistors and likely offer better endurance.

According to Digitimes sources, Apple has obtained the first batch of these new chips, but they will be used in Mac devices, not iPhones. This appears to be the successor to the Apple M1 chip used in the latest MacBook Air and 13-inch MacBook Pro and could be used in the new iMac and the upcoming 16-inch MacBook Pro. If Apple does not have time to implement the chip in these rumored 2021 products, the new silicon will likely be used in 2022 Mac devices.

If 4nm is not small enough, TSMC is also preparing to manufacture 3nm chips. However, these chips will not appear until late 2022 and will be used by Apple and Intel. Given that Intel is currently using the much older 10nm chips, computers using these chips will see a significant increase in performance and efficiency.

Apple's iPhone consistently beats Android phones in performance benchmarks thanks to its powerful A-series chips, and the A15 chip will no doubt keep Apple at the top of the best smartphone guide. But if you want an even more efficient chip and battery life, you may want to wait until the iPhone 14.
