Apple launched the new 2021 MacBook Pro models with its all-new M1 Pro and M1 Max chips. The new chips have enormous processing as well as graphics performance. However, it is never too early to begin speculating what the Cupertino giant will have in store for us in the times to come. Apple's chipmaking partner TSMC has already kicked off pilot production of chips based on its 3nm process. Apple's 2023 Macs and iPhone models will use TSMC's 3nm 'M3' chips based on the N3 process. Scroll down to read more details on the subject.

The report from DigiTimes shares details related to the M3 chips based on the 3nm process which will be used in Macs and iPhones. According to unnamed sources in the industry, TSMC will begin mass production of chips in the fourth quarter of 2022. With that said, shipment of 3nm chips will begin in the first quarter of 2023. This gives us a fair timeline of when Apple might release updated Macs but can not be too sure at this point.
