Bloomberg is reporting Taiwan Semiconductor Manufacturing Co.,  who already produces iPhone and iPad processors, will build the company’s new Mac chips,   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.

Money quotes from the Bloomberg piece:

• this news has negative longer-term implications for Intel, in-line with our concerns around Intel’s future market share (Intel reported earnings after the market close)
• the components will be based on a 5-nanometer production technique, the same size Apple will use in the next iPhones and iPad Pros
• Apple is designing more of its own chips to gain greater control over the performance of its devices and differentiate them from rivals
• The first Mac processors will have eight high-performance cores, codenamed Firestorm, and at least four energy-efficient cores, known internally as Icestorm
• Apple is exploring Mac processors with more than 12 cores for further in the future
• In some Macs, Apple’s designs will double or quadruple the number of cores that Intel provides
• Like Qualcomm Inc. and the rest of the mobile semiconductor industry, Apple designs its smartphone chips with technology from Arm Inc
• The transition to in-house Apple processor designs would likely begin with a new laptop
• Given work-from-home orders and disruptions in the company’s Asia-based supply chain, the shift could be delayed
• Despite a unified chip design, Macs will still run the macOS operating system, rather than the iOS software of the iPhone and iPad
