A16 Bionic Chip in iPhone 14 Reportedly Set to Be Based on '4nm' Process [Updated]

The chip powering the next-generation iPhone will reportedly be based on a "4nm" process, an even smaller process compared to the 5nm process used in the iPhone 12 and iPhone 13 lineups, according to a paywalled preview of an upcoming report from DigiTimes.

Last year, Apple adopted a 5nm process with the A14 Bionic chip in the latest iPad Air and the iPhone 12 lineup. With the iPhone 13, it used an enhanced iteration of the 5nm process. For the iPhone 14, the report claims Apple and its chipmaking partner TSMC are looking to adopt a "4nm" process for the A16 Bionic, the likely name for the chip powering the next-generation iPhone.

A smaller process reduces a chip's physical footprint and offers improved performance and enhanced energy efficiency. A report yesterday by The Information claimed that TSMC and Apple are facing technical challenges in producing a 3nm chip, possibly being a reason the iPhone 14 will feature a "4nm" process instead.

Separate reports from earlier in the year have suggested that Apple has booked all of TSMC's production capacity for the ‌3nm‌ process, which could instead debut in the iPhone 15 and next-generation Apple silicon Mac computers in several years.

With the iPhone 13 and iPhone 13 Pro already released, we now await what Apple has in store for the iPhone 14. While we're still a little under a year away from its launch, rumors suggest that the iPhone 14 will feature one of the most significant iPhone redesigns of the past several years. Get caught up on the latest rumors about Apple's next-generation iPhone using our roundup.

Update: While the ‌DigiTimes‌ report said "Apple will likely adopt TSMC's 4nm process," TSMC refers to the process as "N4P" and describes it as a "third major enhancement of TSMC's 5nm family."

Hmm, back to curves instead of flat edges, I guess?

A4 was 45nm from 45 to 4 in 12 years. or 45 to 5 in 10. Freaking remarkable.

Hate to burst everyone's bubble but there is nothing on these chips that is actually 4nm in dimensions just like the current 5-6-7nm processes that every chip manufacturer is making. It's all a historical node naming convention.

I still don’t understand what is 5 mm. The chip? The tools that made the chip?
Nothing is 5nm. It's a naming convention that hasn't been reality for multiple generations of computer chips.
