The iPhone 14 has not yet been released, and the outside world has begun to circulate news about the iPhone 15.
Recently, it has been reported that the iPhone 15 will completely abandon third-party chips and all carry Apple's self-developed chips.
Today, the topic also quickly rushed to the Weibo hot search list and once reached the top.
According to the Business Times, Apple will use all self-developed chips for the first time on the iPhone 15 released in 2023, including A-series chips and 5G baseband chips.
According to the news, Apple's self-developed 5G baseband chip will support Sub-6GHz and mmWave millimeter wave, using a 5nm process, and will be foundry by TSMC.
In addition, the RF IC supporting the 5G baseband chip will also be foundry by TSMC and will use the 7nm process.
At present, Apple's self-developed 5G chips and supporting RF ICs have been designed, and trial production and sample delivery have recently begun.
The industry predicts that Apple will conduct field testing of 5G chips in 2022 and start mass production in 2023.
In addition, this year's iPhone 14 will use the Qualcomm X65 baseband chip made of Samsung's 5nm process, and the iPhone 14 will be the last generation of iPhones using Qualcomm baseband chips.
As Apple's largest foundry, TSMC has monopolized all orders for iPhone 15 chips, which has also had a great impact on its production capacity and revenue.
According to estimates from the supply chain, based on Apple's 200 million iPhone stock per generation, the 5nm wafer volume equipped with the first generation of self-developed 5G chips on the iPhone 15 will be as high as 150,000 pieces, and the 7nm wafer feeding capacity supporting the IC will reach 80,000 pieces.
In addition, it was previously reported that the A16 chip equipped with the iPhone 14 will use the 3nm process, because TSMC's technology is not yet mature, so it has no choice but to abort.
TSMC's 3nm chip process technology will also be officially announced to be mature in 2023 and put into mass production.
This means that the A17 chip on the iPhone 15 will use a 3nm process for more powerful performance.
Previously, Apple "broke" with Qualcomm, and reached a settlement in 2019, signing a 6-year licensing agreement, and iPhone is still using Qualcomm's baseband chip.
However, for many years, Apple has been working to get rid of the dependence on third-party chips and adopt self-developed chips.
Fortunately, Apple's chip development team did not start from scratch.
Back in July 2019, Apple acquired most of Intel's smartphone modem business for $1 billion, demonstrating its commitment to self-developed basebands.
At present, after three years of development, this research and development has finally borne fruit and begun to trial production and sample delivery.
Apple's pursuit of self-developed chips is not only this, for the Mac and MacBook series computers equipped with Intel chips, Apple has also entered the final transition period.
Today, Apple's Mac and MacBook series have basically moved away from Intel chips and turned to self-developed Apple Silicon processors.
This change will officially complete the transition this year, and the news said that this year Apple will release a number of self-developed chip Mac products, including a new version of the Mac mini and a 27-inch iMac.
Judging from the current news from the outside world, Apple's self-developed 5G chip will be officially put into use in 2023.
The iPhone 15, which is expected to launch in 2023, will be the first iPhone equipped with Apple's self-developed 5G baseband chip.
With the launch of the iPhone equipped with Apple's self-developed 5G chip, perhaps the iPhone signal problem that has been criticized for a long time can be improved.
We'll see.
