Apple will likely begin selling Macs with its own processors in 2021

This news report from Bloomberg cites sources close to Apple who say that Apple is on track to introduce Macs running in-house CPUs and GPUs in 2021. The chips the company is developing are codenamed Kalamata.

Taiwan Semiconductor Manufacturing Co., Apple’s partner for iPhone and iPad processors, will build the new Mac chips, said the people, who asked not to be identified discussing private product plans. The components will be based on a 5-nanometer production technique, the same size Apple will use in the next iPhones and iPad Pros, one of the people said. An Apple spokesman declined to comment, as did Intel and TSMC.

Apple developing multiple Mac chips may be a clue that Apple may not just be thinking about a single new Mac laptop based on in-house silicon but an entire line. It's not clear from this whether these will be additive to the current, Intel-based lineup or whether Apple will began replacing Macs in its current lineup with computers built with these chips in mind. The report does say that one of the chips Apple is developing will be "much faster" than those used in the iPhone or iPad, though they will not yet be sufficient to replace the fastest Intel chips in the MacBook Pro or Mac Pro. Like those iPhone and iPad chips, though, these Mac chips would be built using a 5-nanometer production technique, and they would be made by TSMC.

iPad and the A4 chip

By now you would have digested enough info about iPad from all the overflowing blogs and sites that are covering Apple's latest announcement. But do you know Apple's A4 chip is a ARM Cortex A9 with an ARM Mali GPU? Now i am curious about the 3G part and HSDPA given the BOM list of iPhone 3Gs. Are the original vendors already out of the window with the entry of PA Semi?
