Apple, which makes its own ARM SoCs for its mobile products such as iPhones and iPads, is planning to include ARM chips in Mac laptops alongside Intel CPUs. The ARM chips will handle various tasks during power conservation modes:

Apple Inc. is designing a new chip for future Mac laptops that would take on more of the functionality currently handled by Intel Corp. processors, according to people familiar with the matter. The chip, which went into development last year, is similar to one already used in the latest MacBook Pro to power the keyboard's Touch Bar feature, the people said. The updated part, internally codenamed T310, would handle some of the computer's low-power mode functionality, they said. The people asked not to be identified talking about private product development. It's built using ARM Holdings Plc. technology and will work alongside an Intel processor.

Although Apple only accounted for 7.5 percent of worldwide computer shipments in the fourth quarter, according to data from IDC, the Mac line has long set the standard for design and component improvements. Its feature additions often start new technology trends that other manufacturers rush to follow. Apple and Intel declined to comment. [...] Apple engineers are planning to offload the Mac's low-power mode, a feature marketed as "Power Nap," to the next-generation ARM-based chip. This function allows Mac laptops to retrieve e-mails, install software updates, and synchronize calendar appointments with the display shut and not in use. The feature currently uses little battery life while run on the Intel chip, but the move to ARM would conserve even more power, according to one of the people.

Do you think we will see Dell, Acer, ASUS, et al. produce mainstream dual-processor laptops? How about big.LITTLE clusters in Chromebooks?

    I fail to see where this fits in the big scope. I was always assuming they'd prepare a seamless move to ARM, if just for negotiating with Intel. Hence buying Lattner and his LLVM. LLVM Intermediate Only in the App Store next. But now, Lattner has left and no signs of such preparations.

    For the described use cases of lower-level processing, they could've just talked to Intel and used the ARC (not ARM) built into the chipsets. Maybe some Three-Letter-Agencies objected to interfering with their backdoor there? Or Apple didn't feel like porting iOS or watchOS - which would probably be required if they want to go as far as pulling mail.

    Or an SMC replacement was due? Last time, I looked, it was some H8 kind of chip. Props to Hitachi for that name, maybe Apple now thought it's P.I., or just underpowered for whatever they wanted to do. So the Touch Bar group lobbied to get the job and turned it into job security until retirement?

    The TLAs will be able to spy on each other.
